Developer Tools & SDK Platforms

Auras Pay exposes a RESTful API that lets developers create payment links, track transaction status, manage invoices, and automate payment workflows programmatically. This API-first design targets SaaS platforms and e-commerce operators that need to embed cryptocurrency acceptance into existing systems without building blockchain integrations from scratch. Supported networks include Solana, Ethereum, Bitcoin, BNB Smart Chain, and TRON, with Solana recommended for latency-sensitive integrations given its sub-second finality and native SPL token support. Beyond the core API, Auras Pay publishes an official WooCommerce plugin on WordPress.org that adds a multi-cryptocurrency selector to the checkout page and handles real-time on-chain payment detection automatically. Webhook notifications keep merchant backends in sync with payment confirmations. The platform's non-custodial architecture means developers integrate a pure payment-routing layer rather than a wallet or custodial service, reducing the compliance surface for applications built on top of it.

PassimPay provides an API-first integration architecture for developers building crypto payment flows into applications and e-commerce storefronts. Its public GitHub organization (github.com/Passimpay) maintains 11 repositories including official PHP and Python API wrappers and CMS plugins for WooCommerce, PrestaShop, OpenCart, and Joomla. The documented API at passimpay.io/api-doc covers payment initiation, webhook-based transaction confirmation, and withdrawal automation, with Solana among the supported networks. For teams that prefer minimal code, PassimPay also offers hosted invoice pages and QR-code payment requests requiring no developer setup. The combination of maintained SDK libraries in PHP and Python, ready-made CMS plugins for major e-commerce platforms, and webhook infrastructure for event-driven payment confirmation gives development teams flexible integration paths suited to their stack and deployment model.

CryptoCloud provides a developer-oriented cryptocurrency payment integration suite with multiple connection methods: a REST API that supports webhook callbacks on payment confirmation, a Host2Host server-to-server connection for high-volume or enterprise workflows, embeddable HTML widgets and payment buttons, and a WordPress WooCommerce plugin. A built-in test mode lets developers validate the full invoice and confirmation flow before switching to live payments. The platform's API documentation quality and integration speed have drawn consistent praise in developer reviews on Trustpilot and aggregator sites. All integration paths share a unified API surface that abstracts 40+ cryptocurrencies and multiple blockchain networks behind a single set of endpoints. On Solana, CryptoCloud exposes SOL, USDT, USDC, PYUSD, and TRUMP as payment assets, with Solana's low fees and fast finality making it particularly attractive for developer use cases that require rapid settlement. The REST API also supports bulk payouts, scheduled withdrawals, and customizable fee structures for higher-volume merchants, enabling complex automated payment workflows. By handling wallet address generation, on-chain confirmation logic, and AML compliance at the infrastructure layer, CryptoCloud lets developers add multi-chain crypto payment capabilities without building blockchain-specific confirmation pipelines for each supported network.

CryptAPI provides a developer-focused REST API and accompanying client libraries that give engineering teams a fast path to integrating cryptocurrency payment acceptance without requiring account registration or API keys for initial setup. Developers call a single endpoint with a destination wallet address and a callback URL to generate a unique payment address; webhook notifications then handle payment confirmation asynchronously, enabling event-driven order fulfillment in backend systems. The company publishes open-source client libraries for PHP and Python (Django) and maintains 13 repositories on GitHub covering API integrations and e-commerce plugins. Beyond the core API, CryptAPI ships maintained plugins for WooCommerce, Magento, OpenCart, and PrestaShop — all open source and auditable on GitHub. The WooCommerce plugin, which carries over 400 active installations on WordPress.org, supports 30-plus fiat currencies with CoinGecko-sourced exchange rates refreshed every five minutes and includes built-in QR code payment support. Recent plugin releases have focused on bug fixes and security hardening. This developer toolset spans more than 90 cryptocurrencies across 11 chains including Solana, and has been in production since 2018, providing a well-documented, low-friction integration path for teams building crypto payment flows.

Neglect exposes a public REST API at api.neglect.trade that gives developers access to enriched Solana on-chain data including token metadata, real-time market data, historical price and market cap snapshots, liquidity metrics, holder rankings, wallet holdings, and per-token profit/loss calculations. The endpoints are purpose-built to power bots, portfolio trackers, research tools, and alert systems, with authentication handled via API key bearer tokens. The platform also ships a Model Context Protocol (MCP) server, enabling large language models and AI agents to query token and wallet data through natural language — positioning Neglect at the intersection of on-chain data infrastructure and the growing AI agent ecosystem on Solana. Both the REST API and MCP server share the same authentication system, making Neglect a versatile data layer for teams building automated trading strategies, dashboards, and AI-powered tools across the Solana ecosystem.

Jocc is a no-code creation platform on Solana that provides self-serve tooling for minting NFT collections and deploying SPL tokens without writing a single line of code. It targets digital artists, project founders, and token issuers who want a direct path onto Solana Mainnet through a wallet-connected browser interface built in React and TypeScript. The platform is backed by a custom on-chain program (JoccK5zEaqtCqpfUmAtqmFTNJ35sk1z4D5a47yBJDAT) that enforces minting rules and handles fee collection, while metadata is pinned to IPFS for decentralized, domain-independent persistence. For NFT creators, Jocc handles the full deployment workflow: artwork upload, per-token attribute configuration, royalty settings, supply cap, and a one-time 0.025 SOL creation fee. Collections are formatted for compatibility with MagicEden and Tensor out of the box, meaning minted assets are immediately tradeable on the two dominant Solana NFT marketplaces without additional migration steps. The SPL token generator works similarly — users supply a name, symbol, decimal precision, and initial supply, then deploy a standards-compliant token for a 0.01 SOL fee, making it natively tradeable on any SPL-compatible Solana DEX.

Xyra Labs exposes its multi-chain DeFi infrastructure to builders through a JavaScript and TypeScript SDK alongside enterprise-grade REST APIs targeting sub-100ms response times and 99.9% uptime. The APIs give development teams programmatic access to swap routing, liquidity aggregation, and cross-chain bridging capabilities, enabling them to embed Xyra's infrastructure in their own applications without rebuilding the underlying multi-chain logic from scratch. This developer-first approach underpins the platform's role as a building block for other dApps across the Solana, Aptos, Sui, and EVM ecosystems. The Kana Paymaster, a gasless transaction service for Move-VM chains, illustrates the depth of the developer offering: it processed 396 million sponsored transactions by end of 2025 and served 15 or more dApps, with peak daily activity of 2 million transactions. Account abstraction features — including social login and sponsored transaction flows — layer on top of the SDK to reduce non-custodial wallet friction for end users. With documented quickstart resources, a MiCAR-compliant whitepaper, and security coverage from a Movebit audit, Xyra Labs positions its tools as production-ready infrastructure for teams building multi-chain applications.

The STEM protocol (Solana Trustless Encrypted Messaging) is an open-source, decentralized wallet-to-wallet messaging protocol built with Solana's Anchor framework in Rust, published by the cherry.fun team as a contribution to the Solana ecosystem. The cherrydotfun GitHub organization ships supporting libraries including a stem-sdk, a miniapp-sdk, a chat-embed-sdk (MIT licensed), and an analytics package. These tools allow Solana developers to add wallet-native encrypted messaging and embedded mini apps to their own products. Raffle.sol embedded cherry.fun chat natively using the chat-embed-sdk, and Jupiter Swap integrated into the cherry.fun interface via the miniapp-sdk. By open-sourcing both the protocol and SDKs, cherry.fun positions STEM as shared communication infrastructure rather than a closed application stack.

Tender provides an API-first integration layer for developers embedding crypto payment capabilities without managing their own blockchain infrastructure. Its four API categories — Payment, Agent, System, and Webhook — cover initiating transactions, managing sub-merchant accounts, querying supported chains and exchange rates, and configuring real-time event delivery. All requests use HMAC cryptographic signatures and webhook delivery logs expose failed notification histories for debugging. Two integration paths serve different developer profiles: a JavaScript/React library for custom web applications and a WordPress WooCommerce plugin for e-commerce stores without dedicated development resources. The Agent API supports multi-tenant structures where developers manage downstream merchants under a parent account, suited for marketplace and platform operators. Tender's GitHub organization also forks FacilitatorX402, implementing the x402 HTTP payment protocol for autonomous machine-to-machine micropayments, signaling active development toward agent payment flows.

ICPay ships two primary developer packages: icpay-sdk, a TypeScript library for creating payment intents, fetching token lists, and querying prices and balances using human-readable shortcodes; and icpay-widget, a set of framework-agnostic Web Components with optional React bindings. Eight pre-built UI components cover common commerce patterns including a tip jar, article paywall, donation thermometer, premium content gate, and a simple storefront. A Payload CMS plugin is also available for content-platform integrations. Authentication follows a publishable-key-for-frontend and secret-key-for-server pattern familiar from SDKs like Stripe. Developers initialize the SDK with a chain-specific provider and the API handles transaction construction differences across Solana, Internet Computer, and Base. Token lists are fetched dynamically so new assets can be added without requiring SDK version bumps, and all widget components accept CSS variable theming.

machines.cash exposes a developer and AI-agent infrastructure layer alongside its consumer virtual card product. The platform offers a Claude plugin, MCP connectors, Codex integration, a CLI, and a consumer API at api.machines.cash/consumer/v1 so that developers and AI assistants can execute purchases programmatically. The API uses short-lived scoped session tokens with granular permission scopes covering cards, balances, deposits, and transactions, and requires idempotency keys for financial writes. Agents must gate purchases with explicit user confirmation before execution, making machines.cash one of the earlier payment platforms designed with AI agent use cases as a first-class concern.

Knit (useknit.io) is an API-first digital asset payment infrastructure platform that gives developers a unified REST API to integrate crypto payment capabilities into any business application. The API exposes four core modules — Collections for one-time deposit address generation, API Wallets for persistent customer-specific ledgers, a Business Services Wallet for outbound liquidity, and Payouts for programmatic on-chain withdrawals — all accessible through a single base endpoint. Authentication supports both legacy API keys and OAuth 2.0 client credentials, enabling engineering teams to phase migrations between authentication models without a hard cutover or service disruption. Developer-facing capabilities include event-driven webhooks with persistence and replay functionality, ensuring missed or delayed notifications can be recovered without manual reconciliation. Payment Links allow developers to generate shareable payment URLs without exposing raw wallet addresses to end users, while IP whitelist enforcement on payout requests provides an additional security layer at the API level. Supporting six blockchain networks with a FINTRAC-registered compliance backbone, Knit supplies the infrastructure rails for developers building fintech products — exchanges, neobanks, or marketplaces — that require regulated, multi-chain crypto payment capabilities without building the underlying blockchain plumbing themselves.

PayPerQ provides developer tooling for building pay-per-query and metered API access applications on Solana, enabling developers to monetize API endpoints or data services on a per-request basis. The platform's infrastructure handles the payment processing, access control, and metering logic that would otherwise require custom smart contract development, giving builders a ready-made layer for launching token-gated or usage-based API products on Solana. By abstracting the complexity of on-chain micropayment coordination, PayPerQ makes it practical for developers to build products where consumers pay only for what they use — a billing model that traditional web2 infrastructure supports but that requires significant custom work to implement reliably on-chain. The SDK and API tooling reduces time to deployment for developers building metered access products in the Solana ecosystem.

Bullring Finance exposes its entire cross-border settlement stack — collections, stablecoin routing, and payouts — through a single unified REST API, enabling developers to embed global payment capabilities without building corridor-by-corridor banking integrations from scratch. Supporting infrastructure includes real-time webhooks for settlement event notifications, a sandbox environment for integration and testing, and SDKs and client libraries for multiple programming languages. The API abstracts multi-chain routing logic across Solana, Ethereum, Celo, Polygon, Stellar, and Base, selecting the optimal network for each corridor based on cost, speed, and reliability without requiring the integrating developer to manage chain selection directly. The developer-facing dashboard provides multi-currency virtual accounts, centralized treasury visibility, and real-time liquidity monitoring across all active corridors. This API-first architecture positions Bullring as embedded payment infrastructure rather than an end-user product: fintech companies and payment service providers are the intended integrators, building their own cross-border user experiences on top of Bullring's settlement rails. The platform's early client base — including SUPA, Bluum Finance, Cray Finance, DominiPay, Vector, and Vesicash — reflects this developer and fintech integration model.

Fuse provides a comprehensive developer toolkit called FuseBox, an SDK for building gasless, account-abstracted Web3 applications on iOS and Android. The stack is designed to abstract blockchain complexity from business developers with fintech backgrounds, enabling them to build consumer applications without requiring users to manage private keys or hold gas tokens. Complementary tools include the Smart Wallets API for non-custodial wallet creation, the Trade API for on-chain swap routing, and the Notifications API for real-time transaction alerts. Additional infrastructure components include Fuse Console, a management dashboard for APIs and deployed smart contracts, and a GraphQL API for indexed blockchain data queries. The network is fully EVM-compatible, allowing developers to port Ethereum, Arbitrum, or Polygon smart contracts to Fuse without modification. By late 2025, the ecosystem had grown to more than 150 active projects and 63,682 verified contracts, reflecting strong adoption of the developer tooling layer.

Hotburo functions as a design infrastructure provider for early-stage Web3 and Solana ecosystem teams that lack in-house design capacity. The studio's structured service model covers the complete design lifecycle — from initial brand discovery and competitive research through wireframing, high-fidelity UI design, interactive prototyping, and developer handoff — effectively operating as an outsourced design department rather than a single-engagement vendor. For protocols and applications building on Solana, professional design is a prerequisite for user trust, investor confidence, and developer attention, placing studios with proven crypto experience inside the practical build stack of serious projects. The retainer-based design support offering further positions Hotburo as ongoing infrastructure rather than a one-time resource, maintaining design systems and iterating on product interfaces as client projects scale.

Team Finance offers a suite of developer-oriented tools that allow crypto projects to deploy tokens and launch infrastructure without writing a single line of smart contract code. Token creation uses pre-audited, pre-configured contract templates supporting Solana's SPL standard and the newer Token-2022 standard, covering projects that need transfer fees, confidential transfers, or programmable metadata. White-label portals let teams host branded vesting and staking dashboards on their own domains, a feature popular with larger launches that need a cohesive community experience. A DEX aggregation widget is also available for embedding directly in project dashboards without leaving the platform. The platform's multi-chain approach means the same tooling and UX that works on Ethereum, BNB Chain, Arbitrum, and Base also works on Solana, lowering friction for teams operating across networks. Team Finance supports 26 blockchains and reports serving over 40,000 projects since its launch under TrustSwap. Security coverage includes audits from CertiK, Hacken, BailSec, and Zokyo across its V2 contract suite, with a $50,000 bug bounty program and open-source contract publication across all supported chains. These credentials matter for developer teams evaluating infrastructure they will point their communities toward.

MegaYours describes itself as the "NPM for Web3," offering a module publishing system where developers write reusable blockchain logic once and make it available for any token or project to attach. Modules work with fungible tokens, semi-fungible tokens, and NFTs, and can be added at mint time or dynamically after deployment without asset migration or contract rewrites. Solana developers access the platform through a TypeScript SDK (@megayours/megadata) with Metaplex integration, exposing createMegadata and updateMegadata functions for dynamic NFT metadata. The MegaYours GitHub organization maintains seventeen public repositories spanning the core protocol, Solana bridge, gateway layer, and API service. Teams can compose audited, shared modules rather than rebuilding common patterns — lowering the cost of adding cross-chain utility, staking, or governance to existing token deployments.

Heima Network provides a developer SDK and Agent Hub that let Solana-native and multichain applications integrate chain abstraction without rewriting their core logic. The PumpX case study shows the SDK in practice: the Solana-based meme token DEX adopted Heima's layers and gained the ability to accept liquidity and user accounts from any supported chain, with gas management and cross-chain routing handled automatically by the protocol's infrastructure. The Agent Hub is a permissionless marketplace where autonomous agents register trading, arbitrage, and position management capabilities across chains. Agents access live on-chain data through Heima's APIs and can integrate off-chain signals for complex strategies, with staking-based guarantees backing each participant. AgentKeys extends these capabilities to paired devices, allowing voice or text requests to trigger on-chain actions through permissioned agent channels without the user directly managing transactions.

Automata Network ships modular Rust and Solidity SDKs that give developers a unified interface for attesting computations across Intel SGX/TDX, AMD SEV-SNP, AWS Nitro Enclaves, and NVIDIA H100 hardware families. The toolkit includes ZK-proof compression for on-chain quote verification, reducing million-gas attestation costs to affordable proof sizes through integrations with RISC Zero, Succinct, and Brevis. The DCAP Dashboard automates certificate collateral management and security-patch monitoring, removing a significant operational burden for teams running SGX or TDX environments. Deployments span ten EVM-compatible networks as of November 2025. Production users include Uniswap and Flashbots, and Scroll and Linea integrate the Multi-Prover AVS to distribute proving trust across different mechanisms as part of their Stage 2 decentralization roadmaps. Enhanced multi-prover rollup support shipped in January 2026.

StaFi 2.0 introduced Liquid Staking as a Service (LSaaS), a platform that lets other projects and developers launch their own liquid staking or liquid re-staking tokens without building the underlying staking infrastructure from scratch. LSaaS handles validator management, reward distribution, and smart contract scaffolding across Ethereum, EVM-compatible networks, Bitcoin, Cosmos, and Solana, while the deploying project controls its own branding and configuration parameters. The platform was extended in April 2025 with AI-powered tools under a direction called Staking AI Finance. The Staking Code Agent uses large language models to generate staking-related smart contract code from natural language inputs, lowering the technical barrier for developers building on LSaaS. A companion Staking Assistant Agent provides a conversational interface for optimizing yields, executing staking operations, and receiving personalized recommendations without manual protocol configuration.

Amp, built by Edge & Node, provides a developer-facing blockchain data layer with multiple query interfaces designed to fit into existing engineering workflows. Its most distinctive developer feature is automatic ABI-to-SQL translation: a single call to eventTables(abi) converts smart contract event definitions directly into queryable SQL tables, eliminating the manual parsing work that typically consumes significant engineering time when building on-chain data pipelines. The platform also handles blockchain reorganizations natively, removing custom reconciliation logic that teams would otherwise need to maintain when consuming raw RPC feeds. With Solana support added in April 2026, developers can query Solana events through the same API used for other chains, using familiar SQL, GraphQL, or REST tooling without dealing with chain-specific indexing complexity. Data is stored as Apache Parquet files in object storage such as S3 or GCS, with metadata in PostgreSQL, making it compatible with standard data engineering infrastructure. Ampersend, Edge & Node's second product, extends this developer utility into AI agent infrastructure, providing an SDK and dashboard layer on top of the x402 payment protocol so developers can instrument, control, and monitor agent payment flows programmatically.

The Guru Framework is an open-source developer toolkit published under the dex-guru organization on GitHub, designed to help teams build blockchain workflow automation and AI-powered applications. It includes smart contract templates, a graphical interface for workflow construction, and integration libraries that allow decentralized applications to embed transaction widgets and automated workflows into their own interfaces. The toolkit is built around BPMN (Business Process Model and Notation), an established standard for modeling complex workflows. An Application Wizard tool enables communities to build custom multi-agent applications targeting specific user groups or use cases. For cross-chain coordination, the Guru Framework integrates Chainlink's Cross-Chain Interoperability Protocol (CCIP), enabling workflow steps to span multiple blockchains within a single orchestrated process. Production deployments include Burning Meme, which transitioned from testnet to mainnet using GURU tokens as a liquidity mechanism, demonstrating the toolkit's viability for live applications.

DappLooker provides Python and JavaScript SDKs alongside a RESTful API suite designed for developer and agent-first workflows. The AI API layer includes endpoints for trading intelligence, wallet intelligence, yield and treasury data, and agent infrastructure, all returning structured JSON without additional parsing overhead. The platform supports x402 payments, allowing autonomous agents to purchase data access without requiring human authorization in the loop. Developers can embed DappLooker charts in external applications via the charting API, subscribe to dashboards via API keys, and pay for service access in USDC or USDT. The Agent Infrastructure product line includes a CLI interface that gives developers and autonomous systems direct terminal access to the platform's intelligence outputs, reducing integration work for teams building AI-driven data pipelines.

Ping provides a layered developer toolset designed to integrate cross-chain payments into applications without requiring builders to manage blockchain-specific complexity directly. The Ping API exposes a headless payments interface for programmatically preparing, submitting, and monitoring transactions in any supported asset, with a full OpenAPI specification published at pay.pingpay.io/api for teams building automated payment flows. Embeddable checkout widgets and a hosted checkout option complement the API for applications that prefer a pre-built UI, and webhook notifications keep merchant systems synchronized with payment and subscription lifecycle events. The Ping Dashboard at pay.pingpay.io/dashboard centralizes API key management, payment link configuration, and integration settings across all products. The Pingpay CLI adds a scriptable command-line interface covering wallet management, checkout session creation, payment execution, and payment link management, giving developers a terminal-based path alongside the REST API and browser dashboard. The onramp SDK allows application developers to embed a fiat-to-crypto conversion flow directly in their product, handling Coinbase Onramp integration and NEAR Intents routing behind a single SDK interface. The subscription product's underlying service is open source in the ping-subscription-service GitHub repository, and Ping's public GitHub organization includes a peer-to-peer point-of-sale demo as an additional reference implementation. A structured onboarding process for wallet providers and onramp providers further extends the ecosystem of integrations available to developers building on the platform.

Orynth's AI no-code builder lets anyone deploy Solana applications and tokens by describing their idea in plain language. The platform handles generation, deployment, and hosting entirely, compressing development timelines from weeks to minutes for a first deployment. Supported outputs include websites, decentralized applications, and token launches, with token creation integrated through the Bags API for a full path from concept to live Solana asset without writing code. The builder targets creators who understand the problem they want to solve on-chain but lack the engineering depth to execute without technical support. Workflow utilities including chat history, undo, revert, and editable dashboard elements make the tool practical for iterative development rather than one-shot generation. Orynth integrates Blowfish wallet security scanning to reduce user exposure to malicious transaction prompts, and the platform is transparent about which features remain in beta.

J Tools consolidates more than 40 on-chain Solana operations into a single connected workspace, targeting token creators, project teams, and active traders who would otherwise authenticate across a dozen separate sites during a token's launch-to-market cycle. The platform is organized into eight functional categories covering token creation, liquidity, trading and bundles, marketing utilities, security operations, wallet management, token metadata, and analytics, each grouping related tools under one wallet session. No custom smart contract knowledge is required. The toolkit supports both the SPL and Token-2022 token standards, giving builders access to features such as transfer fees and confidential transfers without writing code. Security-oriented tools handle authority revocation (mint, freeze, update), account freezing, and making tokens immutable. Transparent fee infrastructure reads platform fees from on-chain records rather than calculating them client-side, reducing the risk of front-end fee manipulation. The dual-language interface and regularly updated blog with practical guides reflect a platform built around ongoing builder education alongside its core tooling.
