Overview

Composer for creating a compute budget set compute unit price instruction.

This composer resolves and orders the required accounts for a SetComputeUnitPrice instruction, sets up their access permissions, and delegates construction to the appropriate instruction builder (Instructions::ComputeBudget::SetComputeUnitPriceInstruction).

It is used for attaching a priority fee to a transaction.

Required accounts:

  • Program: Compute Budget program (readonly, non-signer)

Examples:

Compose and build a set compute unit price instruction

composer = ComputeBudgetProgramSetComputeUnitPriceComposer.new(
  micro_lamports: 50_000
)
