PANews reported on November 23 that Port3 Network released an incident report on its X platform regarding a hacking attack. Port3 Network stated that it used NEXA Network's cross-chain token solution, CATERC20. However, CATERC20 has a boundary condition verification vulnerability. After token ownership was relinquished, the function returned a value of 0, which happens to match the ownership verification condition. Therefore, the ownership check failed, making unauthorized access possible. This issue was not mentioned in the CATERC20 audit report. Because Port3 tokens had previously relinquished ownership to achieve greater decentralization, they were in this vulnerable state.PANews reported on November 23 that Port3 Network released an incident report on its X platform regarding a hacking attack.

Curve Finance Pitches Yield Basis, a $60M Plan to Turn CRV Tokens Into Income Assets
The post Curve Finance Pitches Yield Basis, a $60M Plan to Turn CRV Tokens Into Income Assets appeared on BitcoinEthereumNews.com. Curve Finance founder Michael Egorov unveiled a proposal on the Curve DAO governance forum that would give the decentralized exchange’s token holders a more direct way to earn income. The protocol, called Yield Basis, aims to distribute sustainable returns to CRV holders who stake tokens to participate in governance votes, receiving veCRV tokens in exchange. The plan moves beyond the occasional airdrops that have defined the platform’s token economy to date. Under the proposal, $60 million of Curve’s crvUSD stablecoin will be minted before Yield Basis starts up. Funds from selling the tokens will support three bitcoin-focused pools; WBTC, cbBTC and tBTC, each capped at $10 million. Yield Basis will return between 35% and 65% of its value to veCRV holders, while reserving 25% of Yield Basis tokens for the Curve ecosystem. Voting on the proposal runs from Sept. 17 to Sept. 24. The protocol is designed to attract institutional and professional traders by offering transparent, sustainable bitcoin yields while avoiding the impermanent loss issues common in automated market makers. Diagram showing how compounding leverage can remove risk of impermanent loss (CRV) Impermanent loss occurs when the value of assets locked in a liquidity pool changes compared with holding the assets directly, leaving liquidity providers with fewer gains (or greater losses) once they withdraw. The new protocol comes against a backdrop of financial turbulence for Egorov himself. The Curve founder has suffered several high-profile liquidations in 2024 tied to leveraged CRV purchases. In June, more than $140 million worth of CRV positions were liquidated after Egorov borrowed heavily against the token to support its price. That episode left Curve with $10 million in bad debt. Most recently, in December, Egorov was liquidated for 918,830 CRV (about $882,000) after the token dropped 12% in a single day. He later said on…
