Secure Near's Chain Abstraction with Liquid Restaking

NEAR‘s Chain Abstraction comprises social authentication, account aggregation, and multichain intent relay. These elements collectively allow users to transact across various blockchains using a single account and interface, without the need to understand the underlying infrastructure or switch networks.

To realize this vision, two new decentralized infrastructures are required: the Chain Signature MPC network and the Intent Relayer Network. The Chain Signature MPC network, primarily composed of NEAR nodes, functions as a decentralized signer of users’ NEAR accounts, controlling all other accounts on different blockchains. The Intent Relayer Network consists of off-chain relayers that listen to and compete to execute users' intents on different chains. Both infrastructures operate externally to any existing blockchain, including NEAR.

LiNEAR Protocol's role becomes critical here, as it provides a robust security model through multichain liquid restaking, avoiding the pitfalls of centralized and permissioned solutions in pursuit of improved web3 user experience. Restaking secures Chain Abstraction infrastructures for three key reasons: it offers instant security by leveraging existing blockchain security mechanisms, ensures capital efficiency by allowing nodes and stakers of a blockchain to participate with minimal additional capital, and promotes base layer alignment, closely bonding the networks with the blockchains which they serve from which they derive security.

With LiNEAR's liquid restaking solution, the Chain Signature MPC network can become permissionless, mitigating the risks of centralization. Similarly, intent relayers can operate in a trustless manner with restaked verification, removing embedded trust assumptions and enabling users to confidently delegate executions to the relayer network. This entire security framework is supported by $NEAR and $LiNEAR, and other assets such as SOL, ETH, and more in the future, ensuring alignment with different blockchains connected through Chain Abstraction.
