Smart accounts enable advanced features like gas sponsorship, batched transactions, and session keys. Para supports two standards for implementing smart accounts: EIP-4337 and EIP-7702.

​
EIP-4337 vs EIP-7702

UserOperation-based Account AbstractionEIP-4337 introduces a new transaction type called UserOperations that are processed by bundlers and executed via an EntryPoint contract. Your EOA (externally owned account) acts as a signer for a separate smart contract wallet.Key Characteristics:
  • Creates a new smart contract address separate from your EOA
  • Transactions are bundled as UserOperations
  • Requires bundler and paymaster infrastructure
  • Works on all EVM chains today
  • Mature ecosystem with multiple providers
Best For:
  • Applications requiring a dedicated smart wallet address
  • Maximum compatibility across all EVM chains
  • Production applications needing proven infrastructure
