**APIs profiled:** 4

Syndicate is a web3 Transaction Cloud that abstracts blockchain transaction infrastructure for developers. Its REST APIs let teams broadcast transactions across EVM-compatible chains without managing private keys, nonces, or gas — with wallets and private keys secured inside HSM enclaves, guaranteed idempotency, managed gas, EIP-191 personal signing and EIP-712 typed-data signing and attestations, contract and function-signature authorization, IP allowlisting, and reliability-focused signed webhooks for real-time transaction status updates. Syndicate is backed by a16z crypto and ships an official Node.js SDK and a hosted MCP server for AI agents.
