Create Custom User Operation
Enables you to create custom user operations with full control over transaction parameters. User Operations are the transaction format used in Account Abstraction, they are blockchain transactions executed through smart wallets. This endpoint allows you to execute any smart contract function, transfer native tokens, or perform complex operations by defining your own method signatures, call data, and more.

}Create Batch Operation POST
An operation that can join transfers and swaps into a single operation.
Execute User Operation POST
This endpoint queues to execution a user operation on the blockchain, like a swap quote or a transfer. The execution occurs asynchronously as it waits to be included in a block. You can check the status by using the returned hash in the history endpoint or with our webhooks.
