Fund the sub-account

Trades reference the sub-account's collateral balance on the Symmio core. You need balance there before you can open anything.

Signed by: Owner EOA, two transactions.

Function: First, approve(spender = AccountLayer, amount = max) on the collateral token, then depositForAccount(subAccount, amountWei) on the AccountLayer.

depositForAccount (note: not depositAndAllocateForAccount) pulls the collateral from your EOA and credits it to the sub-account's balance on the Symmio core. The AccountLayer signs the inner deposit call to the core on your behalf via its globalSigner mechanism, so from the core's perspective the sub-account is the depositor.

You can re-run this any time you want to top up. You can also withdraw and re-deposit: the sub-account is sticky, the balance isn't.
