Changelog

0.4.0

Known Issues

Features Added

  • Multi-key signing: Ethsigner is initialised with a directory containing a number of TOML metadata files, each of which describe a key which may be used for signing. Upon reception of a Transaction, Ethsigner loads the corresponding metadata file, and signs the Transaction with the key defined therein.
  • Relaxed definition of 'optional' when parsing eth_SendTransaction (empty string, null an "0x" are deemed a missing optional parameter).
  • All endpoints (not just "/") are proxied to the downstream web3j provider (eg. "/login")
  • CI moved from Jenkins to CircleCI
  • Updated to Web3j 4.5.5
  • Updated to JUnit 5

Bugs Fixed

  • When a private transaction is submitted without a nonce, a nonce is generated and inserted. However, if the supplied nonce is too low, the transaction is not resubmitted with a new nonce. Rather an error is returned to the caller (resolved in Besu 1.2.5).
  • Removed intermittent "out of memory" failure during integration testing.
  • Resolved an issue whereby a missing optional field in eth_SendTransaction would fail

0.3.0

Known Issues

  • When a private transaction is submitted without a nonce, a nonce is generated and inserted. However, if the supplied nonce is too low, the transaction is not resubmitted with a new nonce. Rather an error is returned to the caller.

Features Added

  • Updated to use Web3j 4.5.0
  • Accepts Private Transactions addressed with "PrivacyGroupId", not just "PrivateFor"

Bugs Fixed

  • Private Transactions without nonces are now accepted and the nonce populated (see "Known Issues")

0.2.0

Known Issues

  • When a private transaction is submitted without a nonce, then transaction will be rejected. Ethsigner is unable to derive an appropriate nonce for a private transaction, as such the nonce field of eea_SendTransaction is mandatory - if a private transaction is submitted without a nonce an error will be returned. DApps can use the priv_getTransactionCount JSON RPC to determine the correct nonce prior to transaction transmission.

Breaking Changes

  • Command line reworked to specify the source of the key used for transaction signing.
  • EthSigner is supported on Java 11+ only; Java 8 is no longer supported.

Features Added

  • Created EthSigner documentation
  • Allow EthSigner to be deployed as a Docker image
  • Support signing transaction with a key stored in an Azure KeyVault (cloud based software/HSM signing service) (thanks to jimthematrix)
  • Added an Upcheck endpoint
  • Support signing transactions with a key stored in a Hashicorp vault
  • Sign private transaction submitted via eea_SendTransaction
  • Jar files are available from the EthSigner bintray repository.
