# Solana Programs

> 6 Anchor programs deployed on Solana devnet — identity, epochs, wallets, reputation, gas, and zkML verification

Lucid deploys 6 Solana programs that form the on-chain truth layer:

| Program               | Devnet ID                                      | Purpose                                       |
| --------------------- | ---------------------------------------------- | --------------------------------------------- |
| `thought_epoch`       | `8QXiFjguJT4PLVzH6BYNMHXZ3eLRaoF8cwx23EBc44Q6` | MMR root commitment (single/batch/v2)         |
| `lucid_passports`     | `38yaXUezrbLyLDnAQ5jqFXPiFurr8qhw19gYnE6H9VsW` | AI asset registry + x402 payment gating       |
| `gas_utils`           | `EzuUhxtNAz1eRfAPypm6eAepe8fRQBrBPSo4Qcp1w3hm` | Token burn/split CPI                          |
| `lucid_agent_wallet`  | `AJGpTWXbhvdYMxSah6GAKzykvfkYo2ViQpWGMbimQsph` | PDA wallets, policy, escrow, splits, sessions |
| `lucid_zkml_verifier` | `69cJRFGWijD1FdapQ2vz7VP6x2jcXRQyBws9VzzPpqAN` | Groth16 zkML proof verification               |
| `lucid_reputation`    | `4FWEH1XQb7p1pU9r8Ap8xomDYVxdSdwk6fFT8XD63G3A` | On-chain reputation (feedback, validation)    |

All programs are built with [Anchor](https://www.anchor-lang.com/) and deployed to **Solana devnet**.

## Authority

Programs are controlled by a single authority keypair. In production, this will transition to a multisig or DAO governance.

## Verification

Every epoch root committed by `thought_epoch` can be independently verified:

```bash theme={null}
curl https://api.lucid.foundation/v1/epochs/{epoch_id}/verify
```

This checks the on-chain PDA against the off-chain MMR root.
