What is chA(chain abstraction)?

The chA(chain abstraction) is a technology for users which use one chain's entity to integrate with the execution chain, or use entity on the other chain's entity to integrate on the chain. It uses the bridge technology to abstract the tokens, and it can also put additional logic like send the TX relaying one entity.

The chain abstract does not have a certain standard. So the protocols or chains already deployed have a various structure. We will not deep-dive all the projects of the chA(which does not currently supports the paymaster or the gas fee payment by proxy.

The chA is not inspired from the development of the paymaster. But it can be used for the paymaster to manage the pays on the single chain. If you are new to the chain abstraction, please read this first.

Integrating with Paymaster

The chA can integrate by allowing the token on other chains to bridge into other chains, and use it as an gas fee. This can be implemented by the cross-chain(EX: CCTP) or omnichain(EX: LayerZero) and etc. We will deep-dive the integration of the chA and the paymaster by the examples below.
