CAT V1 & V2

Implementation Types

The Chain-Agnostic Token standard has two implementations when being transferred from one chain to another.

  • CAT V1: Burn & Mint

  • CAT V2: Lock & Mint

Token TypesDescription

CAT V1: Burn & Mint

  • New tokens (ERC20)

  • New NFTs (ERC721)

Not yet deployed on any chains

Each time tokens are transferred from one chain to another, it will burn the amount on the origin chain, and mint the amount on the destination chain.

CAT V2: Lock & Mint

  • Existing tokens (ERC20)

  • Existing NFTs (ERC721)

Currently deployed on one chain

When tokens are transferred from the Home Chain to Chain B, it will lock the amount on Home Chain, and mint the amount on Chain B. When tokens are transferred from Chain B to A, it will burn the amount of Chain B, and unlock the amount on Home Chain.

With both implementations, additional chains can be added at any stage.
