SYMMIO Contract

Reads and writes against the on-chain SYMMIO diamond contract — quotes, collateral, allocation, withdraw, and the on-chain market list. This slice targets the Symmio contract directly via viem clients.

Solver-side catalog / limit reads (getMarkets, getLockedParams, getNotionalCapBySymbolId, getOpenInterestBySymbolId) hit the solver REST API and live under Solvers — they are not contract reads even when the numbers ultimately reflect on-chain state.

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

On-chain markets

getOnchainContractMarkets

The authoritative on-chain market list from getSymbols, without solver metadata.

Quote reads

getQuote

Read one quote struct by id.

getSubAccountQuotes

A subaccount’s full quote picture across its Virtual Accounts.

getPartyAOpenPositions

Open positions for a PartyA (Virtual Account).

getPartyAPendingQuotes

Pending quote ids for a PartyA.

Collateral

getCollateralBalance

Collateral-token wallet balance for an owner.

getCollateralAllowance

Allowance the owner has granted the SYMMIO core.

Allocate / deallocate

allocate and deallocate move collateral between an account’s available and allocated balances. They are the same on-chain writes documented under AccountLayer — see allocate and deallocate.

Withdraw

createClassicWithdrawPart

Build a classic (provider-free) withdraw receiver part.

getLastWithdrawRequestId

The most recent withdraw request id for a subaccount.

getPendingWithdrawRequests

The active (non-terminal) withdraw requests for a subaccount.

Query options

Every read ships a matching …QueryOptions factory and …QueryKey builder. See each read’s page for the exact call, and Query options for the shared pattern.

Solvers — solver REST catalog: markets, locked params, notional cap, open interest.
AccountLayer — SubAccount / Virtual Account creation, balances, allocate / deallocate.
InstantLayer — delegated instant flows.
Muon oracle — getDeallocateUpnlSig and other uPnL signature helpers for gated writes.
Errors — every write can surface a viem revert or an SDK-level SymmError.
