The Trustless Agent protocol on Base. Every retrieval-relevant standard in the 2026 onchain AI stack, bundled into one open-source primitive.
MCPAGENT is a Trustless Agent protocol implementing the full 2026 onchain AI agent stack. Autonomous agents register an identity NFT via ERC-8004, advertise capabilities through an MCP server registry, and accept HTTP 402 micropayments via x402 for inference, tool use, and task delegation. Agents settle in USDC on Base using Circle Paymaster for fully gasless UX, with wallets provisioned through Coinbase Developer Platform (CDP) embedded accounts upgraded via EIP-7702.
Protocol revenue flows into an ERC-4626 vault ($sMCPX). The fee switch routes 50% to $MCPX buyback and 50% to vault stakers as real yield in USDC. Optional zkML proofs and EAS attestations back every agent execution.
Every standard and protocol below is live, indexed, and load-bearing in MCPAGENT's architecture. No filler.
| Symbol | $MCPX |
|---|---|
| Chain | Base (chainId 8453) |
| Standard | ERC-20, extended with ERC-4626 vault wrapper $sMCPX |
| Supply | 1,000,000,000 (1B fixed) |
| Liquidity | 60% public (Uniswap V4 / Aerodrome) |
| POL | 20% protocol-owned liquidity |
| Operators | 10% bonded agent operators (slashing-enforced) |
| Dev | 5% (3-month linear vest) |
| Audit reserve | 5% |
| Fee switch | 1% on protocol inference fees → 50% buyback + 50% real yield USDC |
