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 Depend 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 Truly 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 characteristic that lets dApps pay fuel for customers), this was inflicting complications with transaction monitoring.
Different notable fixes embody:
A impasse concern in fee_history that might freeze RPC responsesA panic-inducing overflow bug when Proof-of-Stake force-retire occasions triggered earlyIncorrect fuel restrict upkeep within the transaction packing poolCPU mining timing irregularities
The brand new CIP-166 opcode provides Depend 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 straightforward Ethereum RPC conduct. Transaction receipts acquire an accumulatedGasUsed subject, and Core Area 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 staff 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 key 3.0 “Tree-Graph” improve that shipped in August 2025.
Ought to Node Operators Improve?
Conflux explicitly states this improve is non-obligatory. The fixes goal stability slightly than consensus modifications, so nodes operating older variations will not fork off the community. That mentioned, operators experiencing RPC deadlocks or transaction pool points ought to contemplate upgrading.
The easy 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.
