Chainlink has introduced Token Developer Attestation as the fourth feature of its Cross-Chain Token (CCT) standard.​ This security enhancement allows external verifiers to participate in cross-chain verification processes.​

Key updates:

  • Developers can now attest to token burn/lock events
  • Verification occurs before CCIP mints or releases tokens cross-chain
  • Feature builds on recent LI.​FI integration supporting LINK and SHIB as first CCT tokens
  • Transfers use burn-and-mint mechanism with flat fees and zero slippage

The CCT standard continues to expand its capabilities, following previous features like Programmable Token Transfers and Developer Control & Flexibility.​
