Ethereum was the first blockchain to bring the concept of Chain abstraction. It wants to implement social recovery options, soulbound tokens and wants to implement to pay for transactions without using ETH.
The BNB Chain has been implementing account abstraction since last year and has onboarded several partners, such as Trust Wallet, Biconomy, and Stackup.
Account abstraction in the Near Protocol will see the implementation of subsidized gas fees, email-based onboarding, single accounts for multiple chains, and many other implementations.
Chainlink has already implemented account abstraction with the Chainlink Cross Chain Interoperability Protocol (CCIP) where it allows users to send USDC to five different chains without the user explicitly mentioning the chain name or code.
Zeta Chain has already built an ecosystem of chainless Dapps where users can interact with any chain irrespective of the chain they are on.
