InstantLayer

The InstantLayer contract manages delegated signer access for instant actions. SYMM Trading-SDK exposes the delegation reads as separate APIs: one reads the raw expiry timestamp from delegations, one reads the contract’s computed active status from isDelegationActive, and one reads the scheduled revocation ETA from pendingRevocationEta.

Revocation is two-step and not instant. initiateRevokeDelegation only schedules; the contract keeps enforcing the delegation for the whole cooldown, so every “is it active?” read keeps answering yes until the ETA passes. getPendingRevocationEtas is what makes a revocation in flight visible.

Contract reference: SYMMIO perps-core v0.8.6 docs .

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

Reads

getDelegationExpiry

Raw delegation expiry timestamp from the delegations mapping.

getInstantLayerNonce

Sequential replay nonce for a signer account — sign with nonce + 1.

getIsDelegationActive

Whether the contract considers a delegation active.

getActiveDelegations

Which probed (delegate, selector) pairs are live, in one canonicalizing call.

getRevocationCooldown

How long a revoked key keeps signing — the chain’s global cooldown, in seconds.

getPendingRevocationEtas

Scheduled revocations per selector — the only read that shows one in flight.

Writes

grantDelegation

Grant a delegated signer access to selectors until an expiry.

initiateRevokeDelegation

Schedule a revocation. The key keeps signing until the cooldown ETA passes.

finalizeRevokeDelegation

Clear a scheduled grant once its ETA has passed. Callable by anyone.

Types

InstantLayerAccount

Account identity passed to delegation calls.

Query options

Each read ships a matching …QueryOptions factory and a …QueryKey builder for TanStack Query. See each read’s page for the exact call.

Raw ABI

The instantLayerAbi export is available for consumers that want to call the contract directly with viem. The InstantLayer address is resolved per chain from the config (config.getChainConfig(chainId)), not exported as a standalone constant.
