ethers-signers

Abstracts the transaction and messages signing process, allowing multiple signing key sources, such as:

• hardware wallet,
• mnemonic or
• raw private key.

Currently raw private key signer is supported. Functionality can be easily extended to other sources by implementing the Signer interface.

💻 Code Examples

• Sign a message and recover signer address.

  val privateKey = "0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef"
  val signer = PrivateKeySigner(privateKey)
  
  val messageToSign = "ethers-signers".toByteArray()
  val signature = signer.signMessage(messageToSign)
  val recoveredAddress = signature.recoverFromMessage(messageToSign)

• Sign a transaction.

  val privateKey = "0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef"
  val signer = PrivateKeySigner(privateKey)
  
  val transactionToSign = TxDynamicFee(
      to = Address("0x1be31a94361a391bbafb2a4ccd704f57dc04d4bb"),
      value = "1000000000".toBigInteger(),
      nonce = 12425132,
      gas = 2000000,
      gasFeeCap = "210000000000".toBigInteger(),
      gasTipCap = "21000000000".toBigInteger(),
      data = Bytes("0x1214abcdef12445980"),
      chainId = 1L,
      accessList = emptyList(),
  )
  val signature = signer.signTransaction(transactionToSign)

Other signing examples can be found in tests.
