Biconomy MEE supports native Externally Owned Accounts (EOAs) through two orchestration methods:
  • EIP-7702 Delegation (embedded wallets only)
  • Fusion Mode (external wallets)

​
Wallet Type Support

Wallet compatibility depends on how much control the wallet exposes over the EOA.
  • Embedded wallets (e.g. Privy, Dynamic, Magic) allow developers to install smart account logic directly on the user’s EOA address using EIP-7702.
  • External wallets (e.g. MetaMask, Rabby, Trust) block apps from changing code on user EOAs for security reasons. These require Fusion mode.
Choosing Between EIP-7702 and Fusion: Use EIP-7702 if your embedded wallet supports smart account installation on EOAs. Use Fusion Mode for external wallets where smart account delegation isn’t possible.
