The Chain-Agnostic Token Standard
Nexa is a cross-chain interoperability protocol that makes tokens and NFTs truly chain-agnostic and bridge-agnostic.
We have created a new standard for tokens, Chain-Agnostic Token (CAT), where tokens are native to multiple chains and fungible across EVM and non-EVM chains.
Chain-Agnostic Token contracts are compatible with any bridges (i.e. message passing protocols) such as Axelar, LayerZero, CCIP and Wormhole.
This industry-defining standard enables tokens to exist in a connected manner across all blockchains, and allows for:
No funds escrowed in bridging contracts
No vendor lock-in to message passing protocols.
Key features include:
Token contracts are owned by the token-issuer
Flexibility to add new blockchains at any time
Maximum compatibility with message passing protocols to guard against having a single point of failure
Effortless cross-chain transfers using a burn & mint mechanism for new tokens, and using lock & mint in a proxy contract for existing tokens
The same token address on all EVM chains
The Chain-Agnostic Token (CAT) standard can be applied to:
New tokens
Existing tokens
New NFT collections
Existing NFT collections
Our contracts are fully non-custodial, which means that Nexa never takes custody of project tokens, NFTs or end-user funds.
Our core products support the creation, transfer and distribution of Chain-Agnostic Tokens.
CAT Deployment: An interface that allows for tokens and NFTs to be deployed as Chain-Agnostic Tokens (CATs) in minutes.
CAT Bridge: A bridge to transfer Chain-Agnostic Tokens (CATs) between chains, using multiple message passing protocols as the underlying infrastructure.
