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
