Set Transaction Mode

Send transactions now or later.

By default, FunWallets execute transactions inline.

To generate the transaction and execute it later, toggle the sendTxLater parameter in the environment configuration. To execute the generated transaction, call the FunWallet.sendTx method with the previously generated transaction.
