📄️ For Multi-Rollup Apps
Applications that embrace the "fat app" thesis are leveraging rollups as servers for their operations. These apps maintain contract instances on multiple chains, often requiring inter-contract communication for complex workflows.
📄️ For Chain Abstraction
Chain Abstraction protocols are redefining interoperability by combining resource locks and account abstraction (ERC4337). These enable users to lock funds into wallets on single or multi-chains and gain instant spendable balance across rollups. This seamless spending is powered by a network of solvers who front tokens for User Operations.
