Fetch.ai Exploited for $2M via a Leaked Signing Key
An attacker used a leaked signing key to drain Fetch.ai's Ethereum token converter, then reused the same key to hit NuNet, walking away with roughly $2M across the two AI projects in one coordinated attack.
Fetch.ai has suspended its Ethereum bridge while it investigates and works to contain the fallout. The incident pushes September's crypto hack losses past $333M, with a single attacker responsible for much of this weekend's damage.
An attacker used a leaked signing key to drain Fetch.ai's Ethereum token converter, then reused the same key to hit NuNet, walking away with roughly $2M across the two AI projects in one coordinated attack.
Around 8.7M FET (~$1.53M) was swept from Fetch.ai's TokenConversionManagerV3 contract on Ethereum, while on NuNet the attacker minted 408.5M NTX (~$452K), sending the token down about 95%. Security firms Blockaid and PeckShield attribute both hits to the same wallet cluster. Fetch.ai says it is also investigating unauthorized AGIX and WMTX mints, raising concerns over token supply across affiliated projects.

ZetaChain Shuts Down L1, Migrates ZETA to Solana
ZETA holders voted to shut down the Layer 1 and migrate ZETA to Solana as a native SPL token, with the proposal passing 99.4% in favor on 58% turnout, well above the 40% quorum.
A second proposal will set the shutdown block and balance snapshot height once exchanges confirm support, so no firm date is locked in yet. ZETA slipped about 2.5% on the day as another well-funded Layer 1 opts to fold into a larger ecosystem rather than keep going alone.
ZETA holders voted to shut down the Layer 1 and migrate ZETA to Solana as a native SPL token, with the proposal passing 99.4% in favor on 58% turnout, well above the 40% quorum.
The team is redirecting its focus to Anuma, a private AI app it launched in February that now counts over 300,000 users and has served 1 million model requests across 35 models. It argues the project no longer needs its own chain, and pointed to the upkeep and security load of the Cosmos SDK stack, noting that AI tooling is making such vulnerabilities easier to find. ZetaChain raised roughly $27M three years ago. ZETA will convert 1:1 to a Solana SPL token, keeping its ticker, total supply and vesting schedules, though ZETA on Ethereum and BNB Chain is excluded from the move.

Who Led the Rally: Weekly Gainers Among Top 300
Bitcoin broke $85,000 while Ethereum climbed to $2,700, and the rest of the market followed — only 15 of the top 300 closed the week red.
The biggest stories of the week: NEAR (+77%) and Arbitrum (ARB, +63%). Both moved double digits at multi-billion caps ($5.55B and $1.49B), proof the rally reached the majors, not just microcaps like DRV (+173%) and AKE (+160%).

ECB Launches a Wholesale Digital Euro for Banks
The ECB has gone live with Pontes, a settlement platform that lets banks and eligible institutions settle tokenized-asset transactions in central bank money rather than private stablecoins.
ECB board member Piero Cipollone, who leads the project, has argued that tokenised finance needs a risk-free settlement asset and that only central bank money fits, offering a safe anchor as the market grows. The separate retail digital euro for consumers stays in development.
The ECB has gone live with Pontes, a settlement platform that lets banks and eligible institutions settle tokenized-asset transactions in central bank money rather than private stablecoins.
Pontes acts as a bridge connecting DLT-based securities platforms to the Eurosystem's TARGET real-time gross settlement system, so on-chain trades can settle directly in central bank money. An initial group of banks and DLT operators has already onboarded and can use the service right away, with more committed to join. The Governing Council approved the plan back in July 2025, pairing the short-term Pontes pilot with Appia, a longer-term project for integrated DLT-based capital markets.

Coinbase Launches Retail IPO Access With Oura
Coinbase is opening IPO share allocations to US retail traders, letting eligible customers request shares at the offer price before a stock starts trading on the open market.
The move pushes Coinbase beyond crypto into traditional equity capital markets, putting it head-to-head with brokers like Robinhood and SoFi that have raced to give retail investors earlier access to IPOs.
Coinbase is opening IPO share allocations to US retail traders, letting eligible customers request shares at the offer price before a stock starts trading on the open market.
The feature debuts with Oura, the Finnish smart-ring maker that filed to list on the Nasdaq Global Select Market under the ticker OURA, with an IPO of up to 50M shares targeted at $40 to $44. Coinbase says requests may be filled in full, in part or rejected depending on demand, eligibility rules apply, and allocations are not guaranteed.

Arthur Hayes: “Safety First” Could Drive More Liquidity Into Crypto
Arthur Hayes argues that the recent “Safety First” narrative from major US AI labs could have significant implications for credit markets and global liquidity. In his latest essay, Hayes claims that weaker AI compute demand could pressure the debt financing behind data centers, private credit and captive insurance structures.
Hayes outlines two potential responses if AI compute demand falls: the US government could become a buyer of compute through long-term offtake agreements, or financial authorities could provide liquidity if AI-related debt begins impairing insurance-sector balance sheets. He argues that either path could ultimately increase the amount of money circulating in the financial system.
Hayes concludes that the current choppy crypto market could give way to higher Bitcoin and selected altcoin prices if dollar liquidity continues expanding.
Arthur Hayes argues that the recent “Safety First” narrative from major US AI labs could have significant implications for credit markets and global liquidity. In his latest essay, Hayes claims that weaker AI compute demand could pressure the debt financing behind data centers, private credit and captive insurance structures.
• AI labs currently support over $1T of investment-grade debt and hundreds of billions in lower-quality debt and loans
• Hayes cites an estimated $1.54T in captive reinsurance assets, based on research from Nick Nameth
• US banks have created over $100B of additional money since August 14
• Hayes expects continued monetary expansion to support Bitcoin and selected crypto assets

He argues that either path could ultimately increase the amount of money circulating in the financial system.
His broader thesis is that the combination of AI infrastructure debt, private credit exposure and potential government support creates a setup where additional liquidity could eventually flow into risk assets.
