Symmio Trading-SDK — the SDK surface for builders on HyperEVM
CoreAccountLayerOverview

AccountLayer

The AccountLayer contract is where SYMMIO subaccounts live. Each EOA can own multiple subaccounts; each subaccount can route trades into Virtual Accounts (VAs).

This slice also exposes SYMMIO core balance reads for accounts. The account input can be a subaccount or virtual account address depending on what the underlying SYMMIO method accepts.

The money flow in one line: deposit → available balance → instant trading spends it — there is no allocate step in the instant (lowcap) flow. See Balance Model for the full picture of every balance and both flows.

Contract reference: SYMMIO perps-core v0.8.5 docs .

Each method has its own page with the full signature, parameters, return shape, examples, query options, and raw ABI usage.

Query options

Every read ships a matching …QueryOptions factory for TanStack Query — getUserSubAccountsQueryOptions, getAccountBalanceOfQueryOptions, and getAccountBalanceInfoQueryOptions. See each read’s page for the exact call.

Raw ABI

Reads can be called directly with viem using the exported accountLayerAbi and symmioAbi; each read’s page shows the corresponding readContract call. Writes are routed through the AccountLayer _call proxy so SYMMIO core attributes them to the subaccount — use the SDK write functions rather than calling the ABI directly.
