Tachyon API
The agent-native Solidity/EVM engine — compile, test, simulate, deploy, and call contracts; manage chains and artifacts; plus a JSON-RPC endpoint and MCP surface.
Tachyon is the agent-native Solidity/EVM engine. It exposes its compile/test/simulate/deploy workflow as API, RPC, and MCP surfaces rather than a human-first terminal flow.
