Core Methods
| Method | Description |

transfer(from, to, amount) | Transfers tokens between wallets, enforcing KYC and sanctions checks |

Notes on Staking
- Staking is not tied to nodes.
- Tokens staked are earn token authority-defined fees.
- Token authorities define staking yield curves as a monetary velocity throttle, replacing interest rate levers.
Security and Enforcement
All methods automatically enforce:
- Attestation validity (
attestor_idwhitelisted) - Jurisdictional compliance
- Sanctions list checks against (
attestor_id,attestation_id)
Wallets without valid attestations cannot participate in transfers or staking.
