Описание
Custody-free, policy-gated, receipt-backed execution layer for AI agents. 16 MCP tools across 18 chains (Base, Ethereum, Bitcoin native, Starknet, NEAR, Solana, Stacks, BNB, Rootstock, Filecoin, Aptos, Sui, TON, Tron, XRPL, Stellar, Algorand). One NEAR MPC key authority signs on EVM and BTC, no private keys held anywhere. ShadeGuard policy enforcement, Intel TDX TEE attestation, HMAC-SHA256 receipts, Filecoin and BTFS anchored. x402 protocol settlement with 0.25 percent protocol fee. Public discovery with no signup needed: call yaxgetcapabilities without auth. Instant test key (5 USD cap, 7 day) via POST /api/apply. Install via npx agentx402-mcp-server.

This repo hosts the open-source distribution packages. The platform itself (gateway, ShadeGuard policy engine, TEE attestation, orchestrator, Filecoin/BTFS anchoring) lives in a separate private repository — we ship the bits agents need to use the platform here.
