On-chain verification

The paths in this PR were tested in both directions with a dedicated wallet:

• Injective → Initia: C40C07F513DC1398ABA6B9C92869DB4469135765789BCF589CE2F4EC539756D9
• Initia → Injective: 60E2D7F754C82ED688CDEC06E4AA8A3F7154C2D92BAA640C9E178922FE0BC456
• Initia → Echelon, Inertia, and Cabal: 2F57B40562A087F97E7E88D9F2E51AA040AFF7FFA98946FE5A8BFAA803EBBE77
• Echelon → Initia: 62E268659DEA6785F98E6905156F299C325C2825DF6D6D78CA282E7CC476AD7B
• Inertia → Initia: 08E695F250A704F3154F22C312714B215E784F7CB6948E70CD49A9AAF38B215E
• Cabal raw IBC → Initia: 6360F5CD0DC9906C30A3F2BA2BF96BA75EC3E349D0CCAC9C1AF251D1522CB5A2
• Cabal Decimal Wrapper creation/wrap: 8E8F9E5DE6207AA064CA0481047D14BECFFE66BACBFB19145E5E4AAC4AB0122B
• Cabal wrapped USDC.inj → Initia: A318318905B613D202462C978CF2794607CF9D31BA0F0C9510EA3B33DCDD2CFA

All tested IBC packet commitments cleared. Cabal live state confirms localTokens(raw USDC.inj, 6) resolves to the registered wrapper address.

Validation

• repository validate_assetlist.js passed for all four changed files, including the live Cabal wrapper lookup
• all four files pass assetlist.schema.json
• JSON parsing and git diff --check pass
• independent review confirmed the existing Noble USDC entries are byte-for-byte unchanged

Symbol transition

This PR implements the coexistence phase only: Noble remains USDC, and Injective USDC is introduced as USDC.inj. A later migration PR can rename Noble to USDC.n and promote Injective USDC to USDC after conversion liquidity and application integrations are ready.

Summary by CodeRabbit

• New Features
  • Added support for the USDC.inj asset across Cabal, Echelon, Inertia, and Initia.
  • Included asset metadata, cross-chain transfer details, market identifier, and USDC imagery for display and recognition.
