Chains API

The ERC-4337 smart accounts on a chain, optionally one factory's

The chain's account-abstraction smart accounts by address, 50 per page, optionally only one factory's: factory, deployment, user-operation count and smart-account code.

What it returns

The account-abstraction (ERC-4337) smart accounts that have sent user operations on one chain, ordered by address, 50 per page — all of them, or only those one factory deployed (factory). Each row gives the account, its factory and deployment, its user-operation count and the smart-account code it runs. The order is by address, not by age or activity. Keep passing nextCursor back as cursor until it is null. A factory that deployed nothing gets an empty list.

Request

Send your key in the x-dex-data-key header. Replace each <placeholder> with a real value.

Parameters
Parameter	Description
`factory` query · string · optional	Only the accounts this factory contract deployed: 0x followed by 40 hexadecimal characters.
`cursor` query · string · optional	An opaque cursor from a previous response's `nextCursor`, for the next page. It only pages the chain and factory it was issued for; an empty one, or one over 512 characters, is a 400 (enforced after the API-key gate).
`chain` path · string · required	RHC, ETH, OP and SCROLL only; every other chain returns 400.

Response fields

A JSON response. Every field is always present; null means the value could not be established, never zero.

Response fields of The ERC-4337 smart accounts on a chain, optionally one factory's
Field	Type	Description
`factory`	string \| null	The factory filter, lowercase; `null` when not filtered by one.
`accounts`	object[]	Ascending by address. `[]` when nothing matched.
`accounts[].address`	string	The smart account.
`accounts[].factory`	string \| null	The factory contract that deployed it; `null` when no factory did — typically an ordinary wallet that delegates to smart-account code (EIP-7702).
`accounts[].creationOperationHash`	string \| null	The user operation that deployed it; `null` when no factory did.
`accounts[].creationTransactionHash`	string \| null	The transaction that carried that deployment; `null` when no factory did.
`accounts[].creationTimestamp`	integer \| null	Unix seconds of the deployment; `null` when no factory did.
`accounts[].totalOperations`	integer	The user operations it has sent on this chain. The same address on another chain is counted there.
`accounts[].implementations`	object[]	The smart-account code it runs; `[]` when not known.
`accounts[].implementations[].address`	string	The implementation contract.
`accounts[].implementations[].name`	string \| null	Its verified contract name, e.g. `"Kernel"`; `null` when not known.
`accounts[].proxyType`	string \| null	How it points at that code, e.g. `"eip1967"`, `"eip7702"`, `"erc7760"`; `null` when not known.
`nextCursor`	string \| null	Pass back as `cursor` for the next page. `null` on the last page.

The recent ERC-4337 user operations on a chain
The operations one listed account sent.
The recent ERC-4337 bundle transactions on a chain
The chain's account-abstraction bundle transactions, newest first, 50 per page: transaction, block, time, bundler and how many user operations each carried.
The blocks in a rollup settlement batch
Every rollup block one settlement batch carries, newest first, 50 per page: number, hash, timestamp, transaction count, gas and base fee.
The transactions in a rollup settlement batch
Every rollup transaction one settlement batch carries, newest first, 50 per page: hash, block, position, type, status, sender, recipient, value, fee and gas.
How far an L2's settlement on its parent chain has come
