Binance founder Changpeng Zhao said holding cryptocurrencies on exchanges can in some cases be safer than self-custody. In a post on X, Zhao said hacks involving self-custodied assets often go unreported, while exchange hacks are easier to track and tend to become broader market issues. He added some exchanges respond well to security threats, although defunct exchanges can drag down the overall average.

Access restrictions on high-performance AI models are widening a security gap for much of the crypto industry, leaving many firms without the latest defensive tools as AI developers try to curb cyberattack misuse, Cointelegraph reported. Some organizations, including Coinbase and Shielded Labs, a Zcash ecosystem entity, have secured access to Anthropic’s Mitos and conducted security audits, according to the report. Many large crypto companies, including Binance, still do not have access. Security specialists in the crypto sector argue defenders also need advanced AI models to keep pace with increasingly sophisticated attackers. Recent incidents have included suspected AI-assisted vulnerability attacks targeting Boltz, a non-custodial Bitcoin swap platform, and Coinkite, the maker of the Coldcard crypto wallet, as related damage rises.

Galaxy Research said the potential damage from a security flaw in Coldcard hardware wallets could rise to as much as 2,000 BTC ($130 million), according to The Block.

It explained the incident stemmed from a random number generation flaw in firmware used by the Coldcard Mk3 through Mk5 and Coldcard Q, while issuer Coinkite has already deployed an emergency update. Galaxy Research added total losses could reach 2,055 BTC if a fourth attack, which has not yet been fully confirmed, is included. It said the fourth attack follows the same pattern as the earlier incidents, and that it is working with U.S. federal investigators and exchanges on the response. The research also found 90% of the stolen funds have not yet moved.

Solana validators are advancing two governance proposals, SIMD-0550 and SIMD-0553, to reduce new SOL issuance and increase token burns, CoinDesk reported. If approved, the proposals could raise the network’s daily burn from 650 SOL ($47,000) to as much as 9,000 SOL ($650,000), bring forward the date for reaching Solana’s 1.5% inflation target to 2029 from 2032, and cut issuance by about 18.9 million SOL over six years. To be put to a vote, the proposals need backing from 64.89 million SOL, or 15% of the current amount of staked SOL, but they still need support from about 40 million additional SOL. CoinDesk added that some critics argue a deflationary shift would remain difficult even if daily burns rise, as that would still fall short of the 60,000 SOL issued each day.
