CHANGELOG.md

Changelog

All notable changes to this project will be documented in this file.

Added

• SOLANA chain implementation.

Fixed

• Optimized rpc requests in stellar

[1.7.0] - 2024-09-20

Added

• STELLAR chain implementation.

Changed

• Store only the latest Xcall-Pkg-ID in SUI config.

[1.6.0] - 2024-08-12

Added

• SUI chain implementation.
• Add LastProcessedTxStore to store the chain specific information about the last processed transaction.

Changed

• While switching in between multiple relayer wallet address, set admin before saving config.

  • TxInfo to store the information of transaction in which the message is contained in the source chain. This field is opaque to relayer's core and its type is known only in the chain's implementation.

Migration from 1.0.0 to 1.1.0

We have added support for cosmos chains and xcall contract support. To migrate from 1.0.0 to 1.1.0, you need to update the configuration file and add the cosmos chain details. The configuration file is backward compatible, so you can add the cosmos chain details without affecting the existing configuration.

Major changes in this release is the wallet encryption and decryption. Previously we only encrypted the keystore password, now we encrypt the entire keystore file adding an extra layer of security. The relay will automatically decrypt the keystore file and use it to sign the messages.

We have also added the xcall execution contract support. The relay will now listen to the call message event and execute the xcall contract.

Exection will respect the fees set on configuration. The relay will now calculate the fees and execute the contract.

Migrate keystore files to the new format by running the following command:

important: Before running the command, make sure you have the AWS KMS key id. You can get the KMS key id by running the crly config show command.
