You can implement the `Signer` trait to extend functionality to other signers
|
|
such as Hardware Security Modules, KMS etc.
|
|
|
|
The exposed interfaces return a recoverable signature. In order to convert the
|
|
signature and the [`TransactionRequest`] to a [`Transaction`], look at the
|
|
signing middleware.
|
|
|
|
Supported signers:
|
|
|
|
- [Private key](./type.LocalWallet.html)
|
|
- [Ledger](./struct.Ledger.html)
|
|
- [YubiHSM2](./struct.Yubi.html)
|
|
- [AWS KMS](./struct.AwsSigner.html)
|

// create a transaction

let tx = TransactionRequest::new()

.to("vitalik.eth") // this will use ENS

.value(10000).into();
|
|
|
|
// sign it
|
|
let signature = wallet.sign_transaction(&tx).await?;
|
|
|
|
// can also sign a message
|
|
let signature = wallet.sign_message("hello world").await?;
|
|
signature.verify("hello world", wallet.address()).unwrap();
|
|
# Ok(())
