CHANGELOG — Cardano Rosetta Java 2.3.3 → 2.4.0 Add allow.call_methods (including resolve_smart_wallet_addr), document CIP-113 error codes 5062-5067, and update 2.4.0 middleware version example.


This endpoint returns the version information and allowed network-specific types for a NetworkIdentifier. Any NetworkIdentifier returned by /network/list should be accessible here. Because options are retrievable in the context of a NetworkIdentifier, it is possible to define unique options for each network.

Cardano Rosetta Java 2.4.0: allow.call_methods includes resolve_smart_wallet_addr; allow.errors also includes CIP-113 validation errors 5062-5067. version.middleware_version is 2.4.0 when that release is deployed.
