Ccip-8548 deploy and update fee quoter changeset by AnieeG · Pull Request #1641 · smartcontractkit/chainlink-ccip

AnieeG · 2026-02-05T23:58:29Z

New Fee Quoter Update Changeset (deployment/deploy/feequoterupdater.go):
- Introduces UpdateFeeQuoterChangeset that orchestrates the complete FeeQuoter deployment/update workflow.
- Supports deploying new FeeQuoter contracts or updating existing ones
```
 - New `SequenceFeeQuoterUpdate` that deploys or fetches existing FeeQuoter contracts, it also -
                  - Applies destination chain configuration updates - if input provided
                  - Updates gas and token prices - if input provided
                  - Applies token transfer fee configuration updates - if input provided
                  - Manages authorized caller updates  - if input provided
```
- Automatically updates OnRamp and OffRamp contracts to reference the new FeeQuoter address
  - Added support for updating OnRamp and OffRamp contracts with new FeeQuoter addresses
  - Handles source chain configuration updates for OffRamp
- Handles configuration import from v1.5.0 and v1.6.0 versions ( refer to the ccv/chains/evm/deployment/v1_7_0/sequences/SequenceFeeQuoterInputCreation_Mapping.md)

Fee Quoter Update Workflow

Configuration Import (optional): If PopulateConfig is enabled, imports configuration from previous FeeQuoter versions
Input Creation: Creates FeeQuoterUpdateInput from existing contract metadata or imported configuration
Deploy/Update: Deploys new FeeQuoter or updates existing one with:
- Destination chain configurations
- Price updates (gas and token prices)
- Token transfer fee configurations
- Authorized caller updates
Ramp Updates: Updates OnRamp and OffRamp contracts to use the new FeeQuoter address

@RensR could you please review this sequence?

@RensR And this one as well for 1.5

You determine to call 1.5 import or 1.6 import based on the currently active lane, right?

Let's put this somewhere else

chainlink-ccip/deployment/utils/common.go

Line 58 in dcb7f6e

familySelector, _ = hex.DecodeString(EVMFamilySelector)

+	// 1. applies destination chain config updates
+	// 2. price updates


What is the purpose of doing manual price updates?

The existing connectChain changeset does manual price updates, wanted to keep this equivalent to all ops done in connectchain changeset for feequoter

This should account for DA costs now, which makes it tricky to calculate. @matYang is our DA expert maybe he has some wisdom (aka constant multipliers)

Will keep it same as the existing value for now and come back to it when @matYang can get to this

Please move up to constant, no magic values should be hidden in these functions

This means 1.7 is a new deployment, right? Can we make that more clear.

Can we also move this down to the other if isNewDeployment and merge them?

Price updaters can just be all 1.5 commit stores and all 1.6 offramps on any lane, right? That always gives you everything you need

Yes that's a good call, updating it

This is for a remote chain though, remote chain selector not guaranteed to be EVM
