CHANGELOG — Cardano Rosetta Java 2.3.3 → 2.4.0 Add metadata.address_type=CIP-113 smart-wallet derivation, rejection of staking_credential with CIP-113 (5062), new PLB validation errors (5063/5064); correct the existing success schema/example to account_identifier.address (old page incorrectly showed /construction/payloads fields).

Derive returns the AccountIdentifier associated with a public key. Blockchains that require an on-chain action to create an account should not implement this method.

Cardano Rosetta Java 2.4.0 supports metadata.address_type="CIP-113" (case-sensitive). For this type, an edwards25519 payment public key is used to derive a smart-wallet base address: the configured programmable-logic-base script hash is the payment credential, and the hash of the supplied public key is the stake credential. Do not supply metadata.staking_credential with CIP-113 (error 5062). CIP113_BASE_SCRIPT_HASH must be configured for this operation (errors 5063/5064). Other address types Enterprise, Base, Reward are unchanged; the response uses account_identifier.address.
