Conflux (CFX) Community pushes v3.0.3 testnet improve that includes new CLZ opcode, seven bug fixes, and enhanced RPC performance. Node operators can improve optionally.
Conflux (CFX) Community launched its v3.0.3 testnet improve on February 28, addressing seven bug fixes and introducing CIP-166, a brand new Rely Main Zeros opcode that expands sensible contract capabilities on the EVM-compatible chain.
The improve comes as CFX trades at $0.0458, down 9.31% over 24 hours, with the token consolidating round key assist ranges following its February itemizing on Kraken.
What’s Really in This Launch
Essentially the most consequential repair addresses CIP-78 sponsor flags—particularly, incorrect gasCoveredBySponsor and storageCoveredBySponsor receipt fields that had been showing on reverted transactions throughout testnet replay. For builders constructing on Conflux’s sponsorship mechanism (a core function that lets dApps pay gasoline for customers), this was inflicting complications with transaction monitoring.
Different notable fixes embody:
- A impasse concern in
fee_historythat might freeze RPC responses - A panic-inducing overflow bug when Proof-of-Stake force-retire occasions triggered early
- Incorrect gasoline restrict upkeep within the transaction packing pool
- CPU mining timing irregularities
The brand new CIP-166 opcode provides Rely Main Zeros performance—a low-level operation helpful for bit manipulation in sensible contracts. Whereas technical, these opcodes matter for builders optimizing gas-intensive computations.
RPC Enhancements for Builders
The discharge packs a number of quality-of-life enhancements for builders. The eth_blockByNumber name now helps the pending tag, bringing it nearer to plain Ethereum RPC habits. Transaction receipts acquire an accumulatedGasUsed area, and Core House logs now embody timestamps—small additions that streamline debugging.
A brand new dump subcommand lets operators export all eSpace accounts to JSON, helpful for state evaluation and migration eventualities.
Infrastructure Modernization
Behind the scenes, the crew bumped Rust to model 1.90 and up to date core dependencies together with revm and c-kzg. New GitHub Actions workflows now automate builds throughout Linux, macOS, and Home windows—an indication of maturing improvement infrastructure following the foremost 3.0 “Tree-Graph” improve that shipped in August 2025.
Ought to Node Operators Improve?
Conflux explicitly states this improve is elective. The fixes goal stability moderately than consensus modifications, so nodes working older variations will not fork off the community. That mentioned, operators experiencing RPC deadlocks or transaction pool points ought to contemplate upgrading.
The simple course of: cease your node, swap the executable, restart. New operators can seize v3.0.3-testnet immediately from the GitHub launch web page.
For a community positioning itself as China’s regulatory-compliant blockchain gateway—full with Tether’s CNH-pegged stablecoin launched in November—sustaining infrastructure stability issues. Whether or not this testnet launch indicators an imminent mainnet replace stays unclear, however the improvement cadence suggests lively protocol upkeep forward of potential enterprise adoption cycles.
