fxCore v7.5.0 Release Notes

🕐 Timeline

This is a mandatory upgrade for all validators and full node operators.
The upgrade height is 16838000, which is approx. August 17st 2024, 12:00 UTC.

🚀 Highlights

Enhancements and New Features

• Support for Solidity Contract Bridge Call: Added functionality to enable bridge calls to Solidity contracts, enhancing interoperability across different blockchain networks.
• Automatic Refund and bridgeCallback Interface: Introduced automatic refund mechanisms and the bridgeCallback interface to improve the efficiency and reliability of bridge transactions.
• Pre-compiled Contracts Bridge Call: Enabled support for pre-compiled contracts to perform bridge calls, facilitating smoother and more efficient crosschain operations.
• IBC Bridge Call to fxCore-EVM: Added support for IBC bridge calls to fxCore-EVM, expanding crosschain communication capabilities.
• Pending Pool for Low Liquidity: Implemented a system to add crosschain requests to a pending pool when liquidity is low, ensuring transaction reliability even under constrained conditions.
• Added fxcored export-delegates Command: This feature allows users to export all delegation records from the blockchain, excluding contract delegations.
• Precompiled Staking v2 Contract: Introduced a new precompiled staking v2 contract, with v1 version to be deprecated in future releases.
• Updated Interface Contract: Required a minimum Solidity version of 0.8.10. Contracts using versions prior to 0.8.10 will encounter errors when retrieving bytecode.
• Refactored Precompiled Contracts: Improved execution efficiency of precompiled contracts.
• New Governance Proposals:
• MsgUpdateStore: Added to facilitate proposals to modify store.
• MsgUpdateSwitchParams: Added to facilitate the development of precompiled contracts or specific Cosmos transaction types.
• Metrics for Crosschain Module: Introduced new metrics for the crosschain module.

Bug Fixes

• Zero Gas Attack on EVM Transactions: Fixed an issue where EVM transactions could be exploited with zero gas, preventing potential denial-of-service attacks and ensuring network stability.
• State Rollback Error in Precompiled Contracts: Fixed a state rollback error where the on-chain state was not fully reverted when using try-catch for contract rollback.
• Subgraph Contract Status: Fixed an issue where the subgraph was not retrieving contract status in some cases.

Upgrades

• cosmos-sdk: Bumped to v0.47.13.
• cometbft: Bumped to v0.37.9.
• ibc-go: Bumped to v7.6.0.

Removals

• Legacy Rest API: Removed the legacy REST API.
