The People's Bank of China has decided to establish a non-bank large-scale redemption swap facility (BNSF) in the bond market. When asset management institutions face collective liquidity risks and systemic pressure in the bond market, the BNSF will support bank wealth management subsidiaries and public fund managers to borrow central bank bills from the People's Bank of China for market repurchase financing to purchase eligible bonds or product shares of redeemed public products and pledge them to the People's Bank of China.

Ethereum Foundation researcher Toni Wahrstätter stated that due to compatibility and security issues revealed in a ChainSecurity report regarding EIP-8037 and some smart contracts, core developers have decided to postpone the Hoodi testnet upgrade to Glamsterdam. Issues have been identified, including an increase in remaining gas during transaction execution causing gas count logic underflow and triggering rollbacks, and some contracts underestimating gas usage. ChainSecurity has identified 13 real-world cases and is disclosing them. Toni Wahrstätter stated that the relevant contracts will be investigated and solutions evaluated this week, reminding developers to check their contracts for compatibility with EIP-8037 and EIP-8038.

Ethereum Foundation researcher Toni Wahrstätter stated that the ChainSecurity report reveals that EIP-8037 affects contract interactions. Contracts that hardcode the forwarding of Gas are affected by Gas repricing, and some invariants on which the coding pattern depends are broken, causing the gasleft() value to rise, leading to counter underflow or subcall anomalies. Furthermore, the measurement of the GAS opcode may underestimate usage. Toni Wahrstätter calls on application developers and auditors to investigate and report any issues related to EIP-8037/EIP-8038 in their contracts.
