Get an Account's Unspent Coins

Get an array of all unspent coins for an AccountIdentifier and the BlockIdentifier at which the lookup was performed. If your implementation does not support coins (i.e. it is for an account-based blockchain), you do not need to implement this endpoint. If you implementation does support coins (i.e. it is fro a UTXO-based blockchain), you MUST also complete the /account/balance endpoint.

It is important to note that making a coins request for an account without populating the SubAccountIdentifier should not result in the coins of all possible SubAccountIdentifiers being returned. Rather, it should result in the coins pertaining to no SubAccountIdentifiers being returned. To get all coins associated with an account, it may be necessary to perform multiple coin requests with unique AccountIdentifiers.

Optionally, an implementation may choose to support updating an AccountIdentifier's unspent coins based on the contents of the mempool. Note, using this functionality breaks any guarantee of idempotency.

Request body

network_identifierNetworkIdentifier required— unresolved $ref
account_identifierAccountIdentifier required— unresolved $ref
include_mempoolboolean required

Include state from the mempool when looking up an account's unspent coins. Note, using this functionality breaks any guarantee of idempotency.

currenciesCurrency[] — unresolved $ref

In some cases, the caller may not want to retrieve coins for all currencies for an AccountIdentifier. If the currencies field is populated, only coins for the specified currencies will be returned. If not populated, all unspent coins will be returned.

Response

Expected response to a valid request

block_identifierBlockIdentifier required— unresolved $ref
coinsCoin[] required— unresolved $ref

If a blockchain is UTXO-based, all unspent Coins owned by an account_identifier should be returned alongside the balance. It is highly recommended to populate this field so that users of the Rosetta API implementation don't need to maintain their own indexer to track their UTXOs.

metadataobject

Account-based blockchains that utilize a nonce or sequence number should include that number in the metadata. This number could be unique to the identifier or global across the account address.
