# EVM Contracts

> 10 Solidity contracts for epoch commitment, passports, escrow, wallets, and zkML on Base and Ethereum

Lucid deploys 10 EVM contracts that mirror the Solana programs:

| Contract                | Purpose                                           |
| ----------------------- | ------------------------------------------------- |
| `EpochRegistry`         | Epoch commitment (mirrors thought\_epoch)         |
| `LucidPassportRegistry` | Passport registry + payment gates                 |
| `LucidEscrow`           | Escrow lifecycle (create/release/timeout/dispute) |
| `LucidTBA`              | ERC-6551 Token Bound Accounts for agent wallets   |
| `ZkMLVerifier`          | Groth16 verification via ecPairing precompile     |
| `LucidPaymaster`        | ERC-4337 gas sponsorship                          |
| `LucidPolicyModule`     | ERC-7579 policy enforcement                       |
| `LucidPayoutModule`     | ERC-7579 revenue splitting                        |
| `LucidReceiptModule`    | ERC-7579 receipt tracking                         |
| `LucidSessionManager`   | Session key management                            |

Contracts are written in Solidity and target Base and Ethereum networks.

## Chain Parity

Both Solana and EVM implementations provide equivalent functionality. The key difference is architectural: Solana uses PDAs + Anchor constraints, while EVM uses TBAs + ERC-7579 installable modules.
