# Primev

> AI-native Ethereum infrastructure. Preconfirmations, instant swaps, and agentic payments.

Primev builds core infrastructure for Ethereum's mev supply chain. Our protocols enable sub-second transaction guarantees, gasless token swaps, and machine-to-machine USDC payments — all designed for AI agents and automated systems.

## Products

- [mev-commit](https://docs.primev.xyz): Peer-to-peer preconfirmation protocol for Ethereum. Providers stake ETH and issue binding commitments on transactions before block inclusion. Supports execution preconfs, inclusion preconfs, and builder commitments.
- [Fast Protocol](https://fastprotocol.xyz): Instant token swaps on Ethereum with preconfirmation guarantees. EIP-712 gasless intents for ERC-20 tokens, direct ETH swaps via FAST RPC. Sub-second settlement via mev-commit network.
- [x402 Facilitator](https://facilitator.primev.xyz): HTTP 402 payment protocol for AI agents. USDC payments via EIP-3009 `transferWithAuthorization`. Settle and verify payments programmatically. Powers agent-to-agent commerce.

## Developer Resources

- [Documentation](https://docs.primev.xyz): Full protocol docs, API references, architecture guides
- [FAST RPC Endpoint](https://fastrpc.mev-commit.xyz): JSON-RPC endpoint for preconfirmed transactions. Drop-in replacement for standard Ethereum RPC.
- [x402 Facilitator API](https://facilitator.primev.xyz): REST API for agentic USDC payments. Endpoints: /supported, /settle, /verify
- [GitHub](https://github.com/primev): Open source protocol implementations
- [mev-commit Xplorer](https://observer.mev-commit.xyz): Network explorer showing live preconfirmation activity

## AI Agent Integration

Primev infrastructure is built for autonomous agents:

- **Claude Code Plugin**: `claude plugin marketplace add primev/claude-plugin && claude plugin install primev` — installs 3 skills + 2 MCP servers with 11 tools. No API keys, no costs.
- **MCP Tools**: eth_blockNumber, eth_getBalance, eth_gasPrice, eth_getTransactionReceipt, eth_sendRawTransaction, mevcommit_getTransactionCommitments, mevcommit_optInBlock, mevcommit_cancelTransaction, x402_supported, x402_verify, search_docs
- **Skills**: mev-commit (preconfirmed transactions), fast-protocol (gasless ERC-20 swaps), x402 (agentic USDC payments)
- **x402 Payments**: Agents can pay for APIs and services using USDC via EIP-3009. Facilitator API: https://facilitator.primev.xyz
- **Gasless Swaps**: EIP-712 permit-based swaps require no gas — ideal for agents without ETH
- **FAST RPC**: Drop-in Ethereum JSON-RPC at https://fastrpc.mev-commit.xyz with preconfirmation guarantees
