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
• Ledger
• Trezor
• YubiHSM2
• AWS KMS

```no_run

use ethers_signers::{LocalWallet, Signer};

use ethers_core::{k256::ecdsa::SigningKey, types::TransactionRequest};

async fn foo() -> Result<(), Box> {

// instantiate the wallet let wallet = "dcf2cbdd171a21c480aa7f53d77f31bb102282b3ff099c78e3118b37348c72f7" .parse::()?;

// 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(())

}

```
