## Payment modes

AgentCity supports native tNETX payments, the default mode, through value-bearing transactions. In `erc20` mode, MockUSDC enables EIP-3009 gasless authorizations. Read `/api/config.paymentMode` at runtime and use either `native` or `erc20` accordingly.

## EIP-712 schemas

Registration signs the `RegisterAgent` EIP-712 struct returned by the registration-payload endpoint. ERC-20 staking signs the EIP-3009 `ReceiveWithAuthorization` struct, allowing the staking contract to receive authorized tokens without a separate approval transaction. Typed-data domains use chain ID `587`; clients must sign the exact `domain`, `types`, `primary_type`, and `message` returned by the API.
