Accounts

/blockchain-v2/{asset}/accounts

The Account endpoint returns a list of accounts, which have the following fields:

Field	Description
account	Account as described in the Atlas overview
type	Account type (UTXO, Virtual, Account)
balance	Current account balance in native units
n_debits	Number of debits
n_credits	Number of credits
creation_height	Block height at creation of account
creation_block_hash	Block hash at creation of account
creation_time	Block time at creation of account
creation_chain_sequence_number	The positioning of the account creation transaction relative to all other transactions that have taken place on this chain
last_chain_sequence_number	The positioning of the last transaction that took place for this account relative to all other transactions that have taken place on this chain
last_debit_height	Block height of the last debit
last_credit_height	Block height of the last credit
denomination	The denomination of the balance update. Only present for assets that support multiple denominations, and only when the denomination differs from the asset's default. See Multi-Denomination Assets.

Multi-Denomination Assets

Certain Atlas assets track activity across many independent sub-tokens rather than a single fixed denomination. For these assets, the denomination field in each balance update identifies the specific sub-token the update applies to. The sub-token is identified by its contract address.

When denomination is absent from a balance update, the update's denomination is the asset's default (its symbol, e.g. btc).

Morpho Vault Assets

Morpho Vault assets (MORPHO_VAULTS_ETH, MORPHO_VAULTS_BASE, MORPHO_VAULTS_ARB, MORPHO_VAULTS_AVAXC, MORPHO_VAULTS_OP) aggregate ERC-4626 vault token activity across all MetaMorpho vaults deployed on the respective chain. Each vault is an independent ERC-20 token with its own contract address and decimal precision.

For these assets:

• The denomination field contains the vault's contract address as a lowercase 40-character hex string (no 0x prefix).

• The balance fields are expressed in the vault's own share token units (scaled by that vault's decimals).

• Balances across different denominations are not directly comparable because each vault's share token represents a different underlying asset.

Example: The steakUSDC vault on Ethereum (0xBEEF01735c132Ada46AA9aA4c54623cAA92A64CB) appears as denomination beef01735c132ada46aa9aa4c54623caa92a64cb in balance updates for MORPHO_VAULTS_ETH.
