Universal Accounts give users one account, balance, and interaction point to use across any chain—EVM or not. Instead of managing different wallets and bridging tokens to interact with dApps on different chains, users interact through a Universal Account as if the entire Web3 ecosystem were one network. This is possible because Particle Network’s underlying infrastructure automatically routes liquidity, bridges assets, and manages cross-chain logic using Universal Liquidity. Developers can integrate Universal Accounts easily into their dApps using the Universal SDK. UAs are compatible with both social logins and wallet connections and support gasless, cross-chain operations out of the box.
