📝 Walkthrough

Walkthrough

Added three files: a USDC warp-route token config and a CCTP v2 deploy config linking arbitrumsepolia and sepolia, plus a changeset. The config defines two USDC token entries with bidirectional connections; the deploy file specifies CCTP v2 parameters, addresses, and offchain lookup URLs.

Changes

Cohort / File(s)	Summary
USDC CCTP v2 Testnet Config deployments/warp_routes/USDC/testnet-cctp-v2-fast-config.yaml	New token configuration: two USDC entries (arbitrumsepolia and sepolia) with metadata (address/denom, chainName, symbol, decimals, standard) and bidirectional connections mapping between chains.
USDC CCTP v2 Testnet Deploy deployments/warp_routes/USDC/testnet-cctp-v2-fast-deploy.yaml	New deployment config for CCTP v2 on arbitrumsepolia and sepolia: cctpVersion: V2, contractVersion: 10.1.5, mailbox/messageTransmitter/owner/token/tokenMessenger addresses, maxFeeBps, minFinalityThreshold, type: collateralCctp, and offchain lookup urls.
Changeset .changeset/red-dolls-return.md	Added changeset bumping @hyperlane-xyz/registry with a minor release note: “added testnet cctp v2 fast transfer warp route for testing.”

In `@deployments/warp_routes/USDC/testnet-cctp-v2-fast-config.yaml`:
- Around line 3-18: The two EvmHypCollateral entries (addressOrDenom
"0x7f37ca42A1a39f736339CE12FC2eB8e9EA88FFe5" on chainName arbitrumsepolia and
"0xe0F3680b09751b965CFA24f02f5aa58f0E12343a" on chainName sepolia) need explicit
collateral linkage to the deployed USDC collateral addresses from the deploy
file; update each EvmHypCollateral block to include the underlying collateral
mapping (the deployed USDC address and its chain) so the warp token → collateral
relationship is explicit and matches the connections token entries. Ensure you
add the same collateral reference for both entries and keep symbol/decimals/name
consistent.
