v2.6.0-ccip1.2.0

CCIP 1.2.0 Release

Feature Change Log

USDC

• Support for sending USDC via native integration with Circle’s CCTP protocol.
  • Added USDC token pool to interface with Circle's ITokenMessenger and IMessageReceiver
  • Jobspec changes to support USDC information
  • USDC will be burned by CCTP on source chain and minted by CCTP to token receiver on destination chain.

Billing Changes

• TokenPool destination gas and TokenPool data sizes are now factored in billing to cover NOP costs.
• When the destination chain is a rollup, OnRamp additionally charges CCIP Sender L1 data availability fee to cover NOP costs.
  • GasPrice changed to uint224, with higher-order 112 bits being l1BaseFee of dest L2, lower-order 112 bits being dest gas price.
• Token transfer premium fee min/max changed back to be per-token.

Token Pool Data and Gas Cap

• OnRamp limits return data size from source TokenPool to the token-specific destBytesOverhead. For most tokens, this value is 0.
• OffRamp limits gas passed to TokenPools. Current default to 200K gas.

Public OnRamp

• Allowlist functionalities have been removed from OnRamp. OnRamp is now public.

Chain Expansion

• Add Wemix and Kroma support

Other Misc Changes

• LockReleaseTokenPool contract now has the option to reject outside liquidity.
• MessageId hashing scheme is updated.
• 0-amount token transfer is disallowed.
• PriceRegistry now accepts multiple gas price updates in a single update.
• All contracts implement TypeAndVersion. Previously, TokenPool and PriceRegistry were missing.
• Chain selectors moved to a dedicated repo: https://github.com/smartcontractkit/chain-selectors
• A number of offchain performance optimizations allowing for shorter OCR duration.
• Big versioning initiative to enable straightforward 0-downtime NOP upgrades.
• Fixing nil pointer reference from beta0
• Adding logs to debug missing L1 gas price in #217
• commit plugin - set offchain config n #218
• offchain - explicit initialisations in #219
• Add multi-chain telemetry support, exports OCR telemetry from commit and exec plugins.
• Update collision-resistent BytesOfBytesHashing
