Arcium TS SDK DocsgetComputationFeeFromQueueTx
getComputationFeeFromQueueTx(
arciumProgram,queueTxSignature,mxeProgramId,computationOffset,opts?):Promise<ComputationAccount>
Decode a closed computation's raw fee inputs from its queue_computation
transaction.
Fetches the exact queueTxSignature (no signature scanning), rejects a failed
or unavailable tx, and decodes the queue_computation ix matching
mxeProgramId + computationOffset. Reads no current MXE/cluster state, so it
stays correct across cluster migration.
Pass opts.cluster to additionally bind the match to the comp PDA derived
from that historical cluster (rejects a same-tx queue for a different
cluster's PDA). Omit it for the common case of a single queue per tx.
Returns raw queue-time ix inputs, not lamport fees. Exact reconstruction also
needs queue-time state absent from the ix: cluster cu_price, comp-def
cuAmount, and the callback context: when callbackCuLimit is 0 the callback
priority term defaults from customCallbackInstructionCount.
Parameters
| Parameter | Type | Description |
|---|---|---|
arciumProgram | Program<Arcium> | Anchor program instance (Arcium IDL). |
queueTxSignature | string | Signature of the tx that queued the computation. |
mxeProgramId | PublicKey | MXE program the computation belongs to. |
computationOffset | BN | Computation offset. |
opts | { cluster?: number; commitment?: Commitment; } | cluster binds the match to a historical cluster's comp PDA; commitment maps to confirmed/finalized for the tx fetch. |
opts.cluster? | number | - |
opts.commitment? | Commitment | - |
Returns
The queueTx fee variant.
Throws
Error if the tx is unavailable, failed, or carries no matching
queue_computation instruction.
