## Contracts

| Contract                   | Address                                      | Explorer                                                                                    |
| -------------------------- | -------------------------------------------- | ------------------------------------------------------------------------------------------- |
| NumexRegistryV3            | `0xb2110D936573ADE7122333b316863Ca4e5780f64` | [View on BaseScan](https://basescan.org/address/0xb2110D936573ADE7122333b316863Ca4e5780f64) |
| NumexMarketplaceSettlement | `0x8266a80633a4B7f02B19d438cAE37D1E4075216A` | [View on BaseScan](https://basescan.org/address/0x8266a80633a4B7f02B19d438cAE37D1E4075216A) |

## Configuration

* USDC (Base): `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`
* Platform payout: `0x47A42A274c294eeeFEB57fBF0df6102d6E8A483A`
* Operator: `0x4EFe43cE8298c86370C899eA00EBA37b21aB9d17`
* Settlement has OPERATOR\_ROLE on the registry
* Both contracts are unpaused

## Verification

* `NumexRegistryV3.name()` = "Numex Vaulted Coin V3"
* `NumexRegistryV3.symbol()` = "NUMEX"
* Settlement `registry()` points to the correct registry address
* Settlement `usdc()` returns the correct USDC address
* Settlement `platformAddress()` returns the correct payout address
* Both contracts unpaused
* Unauthorized `settle()` calls revert

## Security

* ReentrancyGuard on all state-changing functions
* Admin renounce protection (DEFAULT\_ADMIN\_ROLE cannot be renounced)
* Custody status state machine enforcement (Vaulted, Redemption Pending, Redeemed, Burned)
* Zero-address validation on all address parameters
* Settlement split math enforced (`residualBps + platformBps <= 10000`)
* Idempotent settlement (duplicate `saleRef` cannot settle twice)
* Pull-based curator residuals (CEI pattern)
* 226 contract tests pass including fuzz tests
