Polygon Announces Lisovo Hardfork on March 4 to Boost Performance and Wallet Compatibility

• Polygon will activate the Lisovo hardfork on March 4 before block 83,756,500, with node operators asked to upgrade in advance.
• The upgrade adds PIP-82 gas subsidies, CLZ support, passkey wallet improvements, flexible fees, and stronger transaction checks.

The Polygon Foundation has announced that the Lisovo hardfork will go live on the Polygon mainnet before block 83,756,500, with activation expected at about 2:00 p.m. UTC on March 4. The network update will require node operators to upgrade Bor to v2.6.0 or Erigon to v3.4.0 before the change takes effect.

The upgrade focuses on network performance, wallet support, and broader smart contract compatibility. Polygon said the release will subsidize agent-to-agent payment costs through PIP-82, while also adding support for the Count Leading Zeros opcode, better known as CLZ. The same package also improves passkey wallet support and adds more flexible fee-tuning tools for the network.

Polygon also included changes aimed at smoother transaction handling. These updates cover transaction re-broadcast mechanisms, peer consensus-based witness verification, and stronger validation checks. Bor v2.6.0 also lists security fixes, bug fixes, and upstream updates from go-ethereum v1.16.8.

The Foundation urged all node operators to migrate to the latest supported versions ahead of the hard fork to avoid service issues during and after activation. 

Local-currency stablecoin activity on Polygon has shot up this year, with JPYC and BBRL boosting payment, lending, and wallet apps on the network. As CNF described, JPYC facilitates merchant payments, wallet transfers, card top-ups, and DeFi liquidity, whereas BBRL offers faster forex settlements.

Lisovo Hardfork Targets Polygon Payments Flow and Wallet Support

The Lisovo hardfork comes as Polygon gears up for payment applications. In its 2026 vision statement, the network said it aims to make money movement faster, simpler, and more reliable across on-chain systems, with special attention on payment flow, fee controls, and wallet usability.

Passkey wallet support is one of the more practical changes in the update. Better compatibility in this area will make wallet access easier for users who rely on modern authentication tools, rather than traditional seed phrase-only setups. CLZ support also enables builders to improve compatibility for smart contracts that depend on this function.

Meanwhile, the network expanded stablecoin use cases through instant USDC VAT refunds for eligible non-EU travelers at airports in Milan, Rome, and Venice. The rollout, supported by Global Blue and Shift4 during the 2026 Winter Olympics, uses the network to speed up cross-border refund payouts.

Despite the Lisovo hard fork news, POL fell 11% over the past 24 hours to $0.1011, while its market cap stood at $1.07 billion, and 24-hour trading volume reached $86.05 million.
