Agent Gas Values

Context

Gas estimation is hard. eth_estimateGas calls have historically caused our agents many issues across different RPC providers and networks. Given that we now have a reasonable dataset on how much gas is needed for different contract methods, we are moving to custom-coding our gas limits using estimates from previous gas usage data.

Standard EVM

Home

Update:

  • Take average limit for one message (50k) and double base to 100k

  • Each additional message dequeued is ~5k gas so double that cost to 10k per message

  • 100k + (num_messages * 10k)

Improper Update:

  • Subset of update gas (update calls improperUpdate)

  • Using same estimation as update

  • 100k + (num_messages * 10k)

DoubleUpdate:

  • Signature check is ~50k

  • Double that for two signature checks in double update 100k

  • Double total for safety to 200k

Replica

Update:

  • 70k on average

  • Double that to 140k (constant)

Prove:

  • 100k on average

  • Double that to 200k (constant since merkle proofs always same size)

Process:

  • Minimum 850k required

  • Double minimum to 1.7M

ProveAndProcess:

  • 1.7M for process

  • 200k for prove

  • 1.9M total

DoubleUpdate:

  • Signature check is ~50k

  • Double that for two signature checks in double update 100k

  • Double total for safety to 200k

XAppConnectionManager

UnenrollReplica:

  • 60k average

  • Double that to 120k

OwnerUnenrollReplica:

  • Cheaper version of normal unenrollReplica without signature check

  • Use same estimate of 120k
