TechFlow News: On March 25, Particle Network announced the launch of its Universal Accounts upgrade solution built on EIP-7702, implemented in collaboration with Web3 wallet service providers Privy, Dynamic, and Magic Labs. This solution enables developers to directly upgrade users’ existing Externally Owned Accounts (EOAs) into Universal Accounts—without requiring asset migration or address changes.
Previously, Universal Accounts already supported cross-chain abstraction capabilities, but required users to migrate assets to a new address—a significant source of friction. The introduction of EIP-7702 eliminates this barrier entirely: developers need only integrate the SDK to instantly equip their applications with cross-chain abstraction functionality. For end users, balances across chains—including Ethereum, Base, Solana, and BNB Chain—are aggregated into a unified asset pool, enabling gas payments using any token—eliminating the need for manual cross-chain transfers, network switching, or holding separate gas tokens on each chain.
