# 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.

## 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
