In the realm of blockchain technology, the continuous development of the Solana ecosystem has garnered significant attention. Recently, a multi-signature management tool named Squads, known for its advantages in security and efficiency, has emerged as a market highlight. In an effort to further enhance the user experience and functionality of smart accounts, the Squads team announced the launch of Squads Policy Network (SPN). This innovative move aims to provide more granular transaction strategy options for on-chain smart accounts through a distributed policy execution mechanism. SPN will leverage Jito's (Re)staking support to achieve the core values of trustlessness and decentralization, allowing users to enjoy a wider range of personalized smart contract services while ensuring safety. This action not only reflects Squads' determination in technological innovation but also hints at the potential and prospects of the Solana ecosystem in the field of smart contracts.
