02.10.2025 - `Delegate` & `Revoke Delegation` Support in Transactions API

We’ve expanded our transaction parsing to include delegation actions:

• New act types delegate – records delegation to another contract or address. revoke_delegation – records revocation of an existing delegation.
  • New response field delegations: captures delegation details, including act_id, chain_id, and address.

"acts": [
    {
        "id": "0",
        "type": "delegate",
        "application_metadata": {
            "contract_address": "0x000000009b1d0af20d8c6d0a44e162d11f9b8f00"
        }
    }
],
"delegations": [
    {
        "act_id": 0,
        "chain_id": "ethereum",
        "address": "0x000000009b1d0af20d8c6d0a44e162d11f9b8f00"
    }
]

This makes it easier to identify smart wallet activations, revocations, and other delegation-related flows directly in API responses. Historical data will be replayed progressively; all new transactions already include delegation information.
