depositForAccount

Deposit collateral into a subaccount’s available balance — the balance instant trading spends and withdrawals draw from. Calls AccountLayer.depositForAccount, which pulls the collateral from the connected wallet into the SYMMIO core and credits the subaccount. For the instant (lowcap) flow this is the whole funding step: deposited funds are directly tradeable, with no allocate step afterwards. See Balance Model.

Requires a prior ERC-20 approval of the collateral token to the SYMMIO core (symmioAddress) — the core is the contract that pulls the funds, so approving the AccountLayer address makes the deposit revert. See getCollateralAllowance and approveCollateral under SYMMIO Contract.


import { depositForAccount } from "@symmio/trading-core";
 
const hash = await depositForAccount(config, {
  account: "0xsub...",
  amount: 1_000000n, // collateral decimals (e.g. 1 USDC at 6 decimals)
});
