description: ZeroDev is account-abstraction / smart-wallet infrastructure for EVM
  chains. It runs an ERC-4337 (and EIP-7702) bundler RPC and a paymaster RPC, both
  exposed as JSON-RPC over HTTPS, plus the Kernel smart-account SDK and a meta-aggregator
  (Smart Routing). Apps sponsor gas, let users pay gas in ERC-20s, and submit
  UserOperations through a single project-scoped RPC endpoint.

  description: Kernel is ZeroDev's modular ERC-4337 and EIP-7702 smart-account
    implementation. The TypeScript Kernel SDK (built on viem / permissionless)
    builds and signs UserOperations, then drives the bundler and paymaster RPCs.
    Kernel v3 supports EIP-7702 delegation alongside classic 4337 deployment.

    paymaster providers behind one project-scoped RPC, with Smart Routing that lets
    users deposit and have assets routed across chains. Provider selection is
