Create

The create method on the BiconomySmartAccountV2 class takes a configuration object when creating a new smart account. See chart and example code below for implementation details. The addresses of ERC-4337 smart accounts follow a deterministic pattern. This enables you to identify the address off-chain before the account is actually deployed.
