* remove error when signing with a different chain - a chain_id mismatch between the signer and the transaction is valid since the behavior is the same between two signers with different chain ids - a specified chain_id should be signed regardless of the chain_id of the signer - refactor `sign_hash` to no longer take an `eip155` flag - it now _just_ signs hashes. EIP155 is specific to transactions, so we now normalize the `v` value in `sign_transaction_sync` * use signer chain_id for tx in trezor signer - use the trezor signer's chain_id if the transaction's chain_id doesn't exist - sets the chain_id in both `sign_tx` and the Signer implementation's `sign_transaction` * use signer chain_id for tx in ledger signer - use the ledger signer's chain_id if the transaction's chain_id doesn't exist - sets the chain_id in both `sign_tx` and the Signer implementation's `sign_transaction` * prefer transaction chain_id in aws signer - uses the signer chain_id if the transaction chain_id doesn't exist - refactor `sign_digest_with_eip155` to take an input chain_id, so the signer chain_id is not used every time. If we want to enforce transaction and signer chain ids to be consistent, this should be undone * add private key signing test for an empty chain_id * Apply suggestions from code review Co-authored-by: Matthias Seitz <matthias.seitz@outlook.de> * Update ethers-signers/src/ledger/mod.rs Co-authored-by: Georgios Konstantopoulos <me@gakonst.com> Co-authored-by: Matthias Seitz <matthias.seitz@outlook.de> |

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:
# use ethers_signers::{LocalWallet, Signer};
# use ethers_core::{k256::ecdsa::SigningKey, types::TransactionRequest};
# async fn foo() -> Result<(), Box<dyn std::error::Error>> {
// instantiate the wallet
let wallet = "dcf2cbdd171a21c480aa7f53d77f31bb102282b3ff099c78e3118b37348c72f7"
.parse::<LocalWallet>()?;
// 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(())
# }
