SendAI

SendAI is an applied AI lab building the infrastructure layer for AI agents operating on Solana. Founded in April 2023 and backed by Solana Labs, the organization describes its long-term mission as building "agent harnesses for financial markets" — a vision the team articulates as becoming the equivalent of Cursor, but for trading. The project has established itself as the dominant open-source provider of AI-to-blockchain tooling on Solana, with a growing suite of products spanning agent frameworks, Model Context Protocol servers, rapid application templates, and a curated skills marketplace.

Solana Agent Kit

SendAI's flagship product is the Solana Agent Kit, an open-source TypeScript toolkit released in December 2024 that allows AI agents built on any model to autonomously execute blockchain operations on Solana. Within months of launch it accumulated more than 1,700 GitHub stars and nearly 900 forks, with monthly NPM downloads exceeding 138,000 — reflecting production adoption well beyond experimentation. The repository has drawn more than 44 contributors and operates under the Apache 2.0 license, making it freely reusable in commercial applications.

The toolkit is organized around a modular plugin architecture covering five categories of Solana action:

Token operations (@solana-agent-kit/plugin-token): SPL and Token2022 transfers, token swaps via Jupiter Exchange, cross-chain bridging through Wormhole and deBridge, and rug-check utilities.

NFT operations (@solana-agent-kit/plugin-nft): Collection creation, minting, listing, and metadata management via Metaplex and 3.Land. An integration with DALL-E enables agents to generate and mint AI-produced artwork without external orchestration.

DeFi operations (@solana-agent-kit/plugin-defi): Staking, lending, and borrowing across Solana's major money markets, plus both spot and perpetual trading. Supported protocols include Raydium, Orca, Drift Protocol, Adrena, Manifest, Meteora, and Jito, among others.

Miscellaneous operations (@solana-agent-kit/plugin-misc): Compressed ZK airdrops, real-time price feed queries via Pyth, CoinGecko token data lookups, and domain registration through SNS and Alldomains.

Blinks (@solana-agent-kit/plugin-blinks): Solana Actions expressed as shareable links, enabling agents to trigger on-chain interactions from conversational interfaces and social contexts.

The kit integrates natively with LangChain, Vercel AI SDK, and LangGraph multi-agent systems. Its implementation follows a React Agent pattern with checkpoint-based memory persistence, supporting stateful multi-turn agent workflows rather than stateless one-shot calls. A Python port (solana-agent-kit-py) extends compatibility to the Python developer community.

Solana Agent MCP Server

In March 2025, SendAI released a Model Context Protocol (MCP) server for Solana, enabling direct blockchain interaction from AI assistant interfaces such as Claude. The server exposes Solana Agent Kit's full capability set — token operations, NFT management, DeFi protocol actions, and cross-chain transfers — as MCP tools accessible through a standardized interface that any MCP-compatible LLM application can call. The repository has garnered more than 160 GitHub stars and 50 forks, and the server appears across major MCP directories including PulseMCP and Smithery.

Solana App Kit and Supporting Infrastructure

Beyond agent-specific tooling, SendAI maintains the Solana App Kit — a rapid development template designed to reduce time-to-production for consumer Solana applications to under 15 minutes. The repository has earned 149 GitHub stars and addresses a separate developer audience: builders who need an integrated starting point for user-facing applications rather than programmatic agent infrastructure.

SendAI also operates a public skills marketplace (sendaifun/skills, 125 stars, 79 forks), providing modular and reusable agent capabilities as composable building blocks for the Solana ecosystem. The solana-new repository (164 stars) serves as a structured knowledge base designed specifically for AI agents building Solana applications — addressing the grounding problem that arises when language models reason over rapidly changing blockchain documentation. A safedev tool provides an isolated development environment that reduces risk when executing agent-generated Solana code.

Across all repositories, SendAI's GitHub organization hosts 34 projects and has attracted 251 followers, reflecting a broad and active developer footprint.

Ecosystem Building: The Solana AI Hackathon

Before its toolkit products reached significant scale, SendAI helped catalyze the Solana AI developer ecosystem through the Solana AI Hackathon — the first large-scale event at the intersection of artificial intelligence and on-chain infrastructure. The event drew more than 400 project submissions across seven prize tracks: autonomous chat agents, meme agents, social and influencer agents, agent infrastructure, DeFi agents, trading agents, and agent token tooling. Total prizes exceeded $250,000, with the top award alone worth $60,000. Judges included Solana co-founder Anatoly Yakovenko and Shaw, the founder of ai16z.

The hackathon's downstream effects were substantial: 65 submitted projects built directly on the Solana Agent Kit, and 102 projects from the event subsequently launched tokens with a combined market cap of approximately $700 million. This outcome established a proof point that AI-native applications could generate real market activity on Solana, drawing further developer attention to the ecosystem and to SendAI's tooling layer.

Strategic Position

SendAI occupies a distinctive position in the Solana ecosystem: it is simultaneously an open-source infrastructure provider, an ecosystem developer catalyst, and an applied research organization with stated ambitions in financial market applications. Its backing from Solana Labs anchors it within the core protocol ecosystem rather than as a third-party dependency, giving its tooling choices potential influence over how Solana's AI agent layer evolves.

The organization's stated long-term direction — building "agent harnesses for financial markets" and becoming a vertically integrated operation that shapes how large language models interact with cryptocurrency markets — suggests a trajectory from pure tooling toward application-layer products built atop that infrastructure. Whether that means autonomous trading interfaces, agent-native financial protocols, or something else remains the open question, but the developer adoption metrics and ecosystem footprint SendAI has accumulated since late 2024 give it a credible platform to execute that vision.
