SourceAnalysis
Circle confirmed CCTP V1 (Legacy) deprecation begins October 31, 2026 and finishes December 1, 2026, forcing apps still using legacy contracts to migrate immediately. The move leaves dYdX Chain operations untouched and keeps Noble USDC fully supported. Developers must examine Circle CCTP V1 deprecation reasons and timeline plus CCTP V2 vs V1 technical differences and migration paths to access Standard and Fast Transfer modes plus hooks and new chain support.
