BITGET STARTS PHASED WITHDRAWAL RESUMPTION FOLLOWING $388 MILLION EXPLOIT

Bitget began restoring withdrawals in stages after an exploit on September 24 drained ~$388 million from its hot and warm wallets, the largest reported crypto theft this year. BTC withdrawals resumed September 29 at 8 AM UTC, with ETH following September 29, USDT on September 30, and all remaining assets, fiat, and P2P by October 2. Bitget said an attacker exploited a vulnerability in a third-party security product to obtain internal credentials and send fraudulent withdrawal commands, bypassing risk controls. Private keys, cold wallets, and user balances weren't affected. Losses will be fully covered by Bitget's 5,500 BTC User Protection Fund. Bitget said it suspects the attackers were "sophisticated" and "state-backed," pointing to North Korea.

STRATEGY PROPOSES DAILY DIVIDENDS TO BRING STRC BACK TOWARD $100

Strategy is seeking shareholder approval on October 28 to implement daily dividend accrual across its four US-listed preferred stocks (STRF, STRC, STRK, and STRD), a timing-only change that leaves existing dividend rates and total payouts unchanged. STRC has traded below its $100 stated value since May, fell to $71 during bitcoin's June correction, and has failed to recover to par despite a 12% annual yield and roughly $1 billion in preferred share repurchases. Daily accrual, paid each subsequent business day, is designed to attract income-focused investors by eliminating reinvestment gaps between distributions and dampening price swings around payment dates. Strategy holds 846,000 BTC acquired at an average cost of $75,416 per coin, meaning bitcoin price moves feed through to these preferred instruments, and the June drawdown in BTC explains STRC's drop below par.

02INNOVATION & LAUNCHES

THE CRYPTOGRAPHIC WORLD COMPUTER

Vitalik Buterin's new paper reframes Ethereum's post-Hegota trajectory as a shift from blockchain to "cryptographic world computer," a hybrid architecture combining traditional consensus with modern cryptography to support properties no pure blockchain can deliver. The roadmap covers FOCIL for censorship resistance, EIP-8288, Lean consensus, state management improvements, and advanced mempool upgrades including transaction privacy. The paper also raises obfuscation as a longer-term primitive that could expand what on-chain computation can offer. Buterin structures the argument through a section-by-section comparison of the Bitcoin whitepaper against Ethereum's 2015, 2025, and 2030 states to show how far the design goals have diverged from their origins.

SOLANA UPGRADE THAT COULD CUT FINALITY FROM 12.8S TO 150MS

Solana's Alpenglow upgrade has moved to public testnet, replacing TowerBFT with a new consensus protocol called Votor that reduces transaction finality from 12.8 seconds to 150 milliseconds. Votor replaces on-chain vote accumulation across 32 slots with direct validator-to-validator messaging that settles in one or two rounds, requiring no changes to wallets or user-facing transaction flows. The rollout requires Agave 4.3 validator software, while Firedancer and Frankendancer clients do not yet support the upgrade, and a tentative mainnet date of September 28 has not been confirmed. The finality reduction would cut the hold periods exchanges impose before crediting deposits, the wait bridges require before releasing cross-chain funds, and the confirmation delays merchants currently face.

WHY ETHEREUM'S L1 STATE OWNERSHIP IS NON-NEGOTIABLE

Offchain computation with onchain proofs creates a cryptographic bulletin board, not a world computer. Ethereum Foundation researcher Barnabé Monnot draws the line at state ownership: Ethereum's network effects derive from its liquidity and accessible onchain state, which allow permissionless actions like liquidations without dependence on brittle third-party APIs or centralized servers. Composability scales with how granular and accessible onchain state is, and offchain state resolution fractures that permissionless composability. The Ethlabs vision follows: L1 as liquidity hub and secure asset layer, with L2s as differentiated state neighborhoods that reinforce and extend L1 network effects while absorbing the offchain economy.

WHY AI AGENTS COULD MAKE BANK RUNS FASTER AND MORE VIOLENT

The real story isn't an imminent agentic bank run but the collapse of cheap bank funding broadly, which will compress return on equity for banks and brokers like Schwab and IBKR that rely on idle sweep-account cash. When agentic bank runs do happen, they'll be faster and more violent than human ones like SVB's, because AI agents have much lower behavioral diversity than humans.

DEFENSE SECRETARY PETE HEGSETH HOLDS BITCOIN IN A COINBASE WALLET

Defense Secretary Pete Hegseth disclosed Bitcoin holdings of $16,000-$65,000 in a Coinbase wallet via his 2025 OGE financial disclosure, split across two capital gains entries. The filing shows no Bitcoin transactions above $1,000 during 2025, indicating Hegseth held a passive position throughout the year. His exposure is modest compared to President Trump's June filing, which reported over $50 million in Bitcoin and $1.2 billion in crypto-related earnings. The disclosures from multiple senior US executive branch officials mark Bitcoin ownership as established at the cabinet level, with Coinbase serving as the disclosed custodian for at least one sitting secretary.

CIRCLE'S TAZAPAY ACQUISITION IS REALLY ABOUT BUYING AN OFF-RAMP FOR USDC

By tracing on-chain flows behind Circle's September 8 announcement to acquire Tazapay, a Singapore B2B cross-border payments firm, it seems about a third of Tazapay's payout business is already funded in USDC (up from under 10% in June), with monthly redemptions into Circle hitting $562 million in the first 25 days of September. Circle isn't buying a future USDC channel but a client that already burns over half a billion dollars of USDC monthly through Circle Mint plus the fiat off-ramp rails on the other side, since Tazapay's product is one-directional (stablecoin in, fiat out) with almost no on-chain revenue (2 basis points). The real business is the FX spread at the off-ramp, not the blockchain layer itself.
