Odaily reports: Toni Wahrstätter posted that ChainSecurity's report indicates EIP-8037 has compatibility and security issues with certain smart contracts, and core developers decided last week to delay the Hoodi testnet upgrade to Glamsterdam. The issues discovered include that remaining Gas during transaction execution may increase, causing some Gas counting logic to underflow and trigger a revert, or triggering code paths that should not have been executed, making transactions appear successful; some contracts may also underestimate Gas usage because they cannot correctly calculate Gas consumption during calls. ChainSecurity previously stated it had found 13 real cases and is conducting responsible disclosure with the affected projects.Toni Wahrstätter said that this week further investigation of the relevant contracts and evaluation of solutions will be conducted, and the work may require coordination among application developers, core developers, auditors, and node operators, and in the worst case may require adjusting the protocol specification. He reminded application developers and auditors to check contract compatibility with EIP-8037 and EIP-8038 and to report issues promptly.
Polygon has officially launched its native liquid staking token, sPOL, designed to enhance returns for POL token stakers. As Polygon’s native liquid staking token, sPOL unlocks approximately 3.6 billion staked POL tokens and grants stakers priority access to transaction fee revenue sharing. Currently, only about 4%–5% of POL is liquid; sPOL addresses the issue of idle capital being unable to participate in DeFi yield opportunities. Users can migrate existing stakes to sPOL via the Polygon Staking Portal—without waiting periods and with uninterrupted rewards—while new stakes will automatically receive sPOL. The initial sPOL redemption ratio is 1:1, increasing as staking rewards accrue. sPOL supports liquidity provision, collateralization, and yield-boosting DeFi strategies, and can be redeemed at any time for POL plus accumulated rewards. The token was initially launched by Polygon Labs and audited by ChainSecurity and Certora; official liquidity will be seeded through an on-chain liquidity pool. Polygon cautions that sPOL carries smart contract risk, validator misbehavior penalty risk, and market volatility risk.
