Tatum

Tatum is a blockchain infrastructure platform that sits between application developers and the raw complexity of running or connecting to blockchain nodes. Rather than requiring teams to manage their own RPC endpoints, write custom indexing pipelines, or stitch together several third-party services, Tatum provides a single unified layer covering RPC access, indexed blockchain data, wallet management, real-time notifications, and token pricing across more than 130 networks. Founded in 2017, the platform has evolved well beyond its origins as a developer toolkit. Today Tatum positions itself as enterprise-grade infrastructure, holding AICPA SOC 2 and ISO 27001 security certifications and ranking in CertiK top 10 percent for code and security standards. Its customer base spans crypto exchanges, fintech companies, and Web3 startups, with named clients including Binance, Celo, and Zengo. At its foundation, Tatum operates an intelligent RPC routing layer that gives developers access to nodes across 130 blockchain networks including Solana, Ethereum, Bitcoin, Polygon, Arbitrum, Base, BNB Smart Chain, Monad, and dozens of emerging L1s and L2s. Rather than hitting a single node endpoint, requests are distributed through a gateway that performs geo-routing, load balancing, automatic failover, and data caching. The result is a claimed 99.99 percent uptime, sub-50ms latency, and throughput of up to 200 requests per second per connection, with WebSocket support for persistent real-time streams. Beyond raw RPC access, Tatum provides a Blockchain Data API, an indexed layer that normalizes data across chains into a consistent schema. Developers can query wallet balances, token holdings, transaction history, NFT metadata, DeFi positions, and staking data using a single API surface regardless of which underlying chain they are querying, eliminating the need to run custom indexers or parse raw block data. The Smart Wallet SDK abstracts away key management and transaction signing. Developers can create MPC wallets, sign transactions, sponsor gas fees on behalf of users, and build custodial or non-custodial flows without exposing private keys to application servers. The platform also ships a Key Management System for enterprise custodial use cases where secure offline signing is required. A fee estimation API lets applications dynamically calculate optimal gas costs before submitting transactions, reducing failed transactions and overpayments across supported networks. One of Tatum historically notable features is its webhook notification system, now expanded with WebSocket support launched in mid-2026. Developers register addresses, contract events, or on-chain conditions, and Tatum delivers push notifications when those conditions are met, eliminating the need to poll nodes or run dedicated event listeners. The platform also added price-change alerts in July 2026, extending real-time monitoring to token price movements by contract address or symbol. The WebSocket streaming layer enables persistent connections for applications that need continuous feeds of blockchain state, covering trading dashboards, portfolio trackers, block explorers, and on-chain monitoring tools. In 2026 Tatum launched AI Builder at ai.tatum.io, a tool that lets developers describe a Web3 application in natural language and have Tatum agent layer assemble the underlying chain integrations, API calls, and wallet connections automatically. Early community demos showed users building wallet trackers, token security checkers, and crypto news digests from single prompts. Alongside the builder, Tatum integrated with the Model Context Protocol, the emerging standard for connecting AI agents to external data sources and actions. Through MCP-native tooling, autonomous agents can read blockchain state, look up token prices, send transactions, and interact with wallets directly, giving AI systems production-grade blockchain infrastructure without requiring manual API wiring. Tatum provides dedicated infrastructure for Solana, including RPC gateway access to Solana mainnet with the platform standard routing and failover guarantees. Through the Blockchain Data API, developers can query Solana wallet balances, SPL token holdings, NFT collections, and transaction histories using the same normalized interface applied to other supported chains. The Smart Wallet SDK supports Solana transaction signing and gas sponsorship flows. Tatum has also tracked Solana slot time reduction from 400ms to 350ms, with a longer-term target of 200ms, as a meaningful improvement for latency-sensitive applications. In April 2026 Tatum announced an integration with Walrus, Mysten Labs decentralized storage protocol, to address the limitations of standard RPC nodes for historical blockchain data. The partnership allows Tatum-connected applications to offload large archival datasets to Walrus distributed blob storage layer, reducing costs for analytics platforms and on-chain archiving tools. Tatum offers a free tier that includes RPC access, the Blockchain Data API, webhooks, and the Smart Wallet SDK with no credit card required. Paid plans scale up request limits, add priority support, and unlock higher throughput tiers. The developer documentation at docs.tatum.io covers all supported chains and APIs with Markdown-native formatting and an OpenAPI specification available for programmatic access. A JavaScript SDK is the primary client library, with additional integration paths through MCP for agent frameworks. Tatum occupies the infrastructure middleware layer of the multi-chain development stack, letting small teams ship multi-chain applications without dedicated blockchain infrastructure engineering. For Solana developers in particular, it provides a production-ready gateway to the network alongside the cross-chain tools needed to build applications that span multiple ecosystems.
