List supported chains

GET /api/supported-chains

List every chain this deployment can relay to, including display metadata, native currency details, and block explorer links. Only chains that are currently enabled are returned. This endpoint requires no authentication.

Each chain includes a capabilities object: {eip7702, flashBlocks, hypercore}. HyperCore chains take signed exchange actions (see the HyperCore endpoints), not EVM transactions.
