Vertex Executes - Websocket and REST API


All executes go through the following endpoint; the exact details of the execution are specified by the JSON payload.




All executes are signed using EIP712. Each execute request contains:

  1. A piece of structured data that includes the sender address

  2. A signature of the hash of that structured data, signed by the sender

You can check the SDK for some examples of how to generate these signatures.

See more info in the signing page.

Sender Field Structure

The sender field is a solidity bytes32 . There are two components:

  • an address that is a bytes20

  • a subaccount identifier that is a bytes12

For example, if your address was 0x7a5ec2748e9065794491a8d29dcf3f9edb8d7c43, and you wanted to use the default subaccount identifier (i.e: the word default) you can set sender to 0x7a5ec2748e9065794491a8d29dcf3f9edb8d7c4364656661756c740000000000 , which sets the subaccount identifier to 64656661756c740000000000.


For DepositCollateral and WithdrawCollateral, the amount specifies the physical token amount that you want to receive. i.e. if USDC has 6 decimals, and you want to deposit or withdraw 1 USDC, you specify amount = 1e6.

For all other transactions, amount is normalized to 18 decimals, so 1e18 == one unit of the underlying asset. For example, if you want to buy 1 wETH, regardless of the amount of decimals the wETH contract has on chain, you specify 1e18 in the amount field of the order.
