Technical Details

Implementation

EIP-7702 introduces a new transaction type (0x04) that allows EOAs to set their code based on existing smart contracts through signed authorizations.

0xef0100 || address // Delegation designation format

Security Considerations

  • • Built-in revocation mechanism
  • • Chain-specific or universal deployment options
  • • Storage namespace protection
  • • Secure delegation patterns

Benefits

EIP-7702 maintains compatibility with existing infrastructure while providing enhanced functionality:

  • Compatible with EIP-4337 account abstraction

  • Works with existing smart account implementations

  • Flexible authorization schemes
