Create Wallet
Create a new Zet-managed smart wallet for one of your users. The wallet address is deterministic — it will be the same across all supported EVM chains.
The wallet is lazily deployed: the on-chain smart contract is only deployed when the first transaction is executed on that chain, with deployment gas sponsored by Zet.
