      • caver.utils.publicKeyToAddress will derive an address from a public key.
  • Supports a method that recovers public keys from a transaction instance. (#267)
    • This method recovers public keys from the signatures or feePayerSignatures field of the transaction.
      • tx.recoverPublicKeys will recover public keys from signatures.
      • tx.recoverFeePayerPublicKeys will recover public keys from feePayerSignatures.
  • Adds a new layer named Validator. (#265, #268)
    • caver.validator is a layer that provides validation methods that are necessary to use Klaytn.
      • caver.validator.validateSignedMessage will validate the signature signed on a message.
      • caver.validator.validateTransaction will validate signatures and feePayerSignatures in the transaction.
      • caver.validator.validateSender will validate signatures in the transaction.
      • caver.validator.validateFeePayer will validate feePayerSignatures in the transaction.
  • Adds a network provider that manages the network connection as a field of Caver class. (#251)

Fixed

  • Fixed a typo in method name. (#256)
    • Fixed the method name generateRolBasedKeys to generateRoleBasedKeys in KeyringFactory class.
  • Fixed an encoding/decoding logic that occurred when if the length of a dynamic array is zero. (#257)
  • Fixed a decoding issue for LegacyTransaction logic. (#266)
    • If a number type field (e.g., nonce, gas, gasPrice, value) has 0 value, it decodes as bigInteger.
  • Fixed a build problem when using an IntelliJ. (#259)
