Unsupported Calls

Smart Wallet implements an Ethereum Provider JavaScript API (as detailed in EIP-1193) and follows the ERC-4337 standard for account abstraction.

This means that apps interacting with Smart Wallet can expect it to behave like a regular Ethereum Virtual Machine (EVM) account. However, there are some calls that are not supported by Smart Wallets for incompatibility or security reasons. This is a list of calls that are not supported:

  • Self Calls: This refers to the ability of an app to use the user's account to call itself.
  • CREATE: This refers to the ability of an app to create a new contract using the OPCODE CREATE.

Self Calls

For security reasons, we do not allow 3rd party apps to make calls to a user's own Smart Wallet address. This could allow apps to change owners, upgrade the user's account, or cause other issues.

CREATE

This is a limitation of the ERC-4337 standard and smart accounts. Currently, we do not support the CREATE opcode for smart contracts deployment. Future versions of Smart Wallet may support it.
