MegaETH joined Rabby's default network list in February, less than a year after the chain went live on mainnet. The wallet is now reportedly removing MegaETH from its built-in networks, cutting the chain from the list users see out of the box.

User funds are not affected: MEGA and other assets stay onchain at the same addresses. Access can be restored by adding the network manually in Rabby under Settings, Networks, Add Network, with the RPC mainnet.megaeth.com/rpc and chain ID 4326.

Wallets typically drop low-traffic chains to reduce maintenance work, so losing default support in a major EVM wallet is a visibility hit for a young network.

Brazil's Mercado Bitcoin froze deposits and withdrawals after a cyberattack with over $40M in suspected losses. It's the second exchange hack in four days, after Binance's $6.36B.

So what happens next? We traced the fate of all 69 exchanges hacked for $1M+ since 2011: half survived on their own, one in seven was sold and one in three is gone. The dead were mostly small, with a median hack of $6.5M vs $26M for survivors.

The best early signal is the clock. Survivors reopened withdrawals in a median of 5 days, the dead never did. Binance reopened in 2.4 days, survivor territory.

MB has no reopening date yet. That's the number to watch.

Hong Kong users of Crypto.com have been told by email that the exchange will stop serving them through its consumer app from February 1, 2027. The notice, sent by local operating entity Foris DAX HK Limited, cites regulatory changes and says all local services will be wound down in phases.

Foris DAX HK applied for a virtual asset trading platform (VATP) license in February 2024, and the application is still pending with the Securities and Futures Commission more than two and a half years later.

Affected users will need to withdraw their assets during the wind-down. The move leaves one of the largest global exchanges without a consumer app in Hong Kong while its license bid remains unresolved.

A year after launching RECALL in October 2025 to power open evaluation of autonomous AI agents, the Recall Foundation board decided to wind down, citing weak protocol adoption, operating costs and growth outlook. The Foundation says the move is not the result of a hack.

The Foundation will burn about 358.6M RECALL under its control, roughly 35.86% of total supply, cutting it to an estimated 641.4M tokens.

Holders get no buyback, redemption or distribution. The remaining ~$3.7M in stablecoins and fiat goes to creditors ($3.45M) and wind-down costs, and the Foundation stops liquidity support, so exchange delistings are expected.

Staked RECALL is not burned and the unstaking cooldown is removed. app.recall.network turns read-only on November 30, with Cayman liquidation expected in Q1 2027. Recall Labs, a separate company, is not covered by the wind-down.

Laundering of the roughly $6.43 billion stolen from Binance has spread across 11 blockchains, and cross-chain bridge Relay is now moving to cut off its own routes. The protocol says some transactions and routes are paused or delayed while it blocks addresses tied to the hacker.

Relay is working with Binance and law enforcement. The FBI had earlier urged DeFi services and other virtual asset providers to block transactions linked to addresses used by North Korea's TraderTraitor group to launder the proceeds.

About $2.85 billion, or 44% of the stolen funds, has already been frozen or seized, while roughly $3.24 billion remains in linked addresses.

The move contrasts with THORChain, whose founder has defended permissionless settlement despite pressure to block hack-linked flows. Relay users may see delays on some routes while the restrictions stay in place.

On November 2, Brazil's Mercado Bitcoin froze deposits and withdrawals after a cyberattack with over $40M in suspected losses. It came four days after Binance lost $6.36B, the largest crypto hack ever. Two exchanges, two very different sizes, one question: what happens to an exchange after it gets hacked?

We went through every centralized exchange hacked for $1M or more since 2011. There are 69 of them.

The split

• Survived on their own: 35 (51%)
• Rescued by a buyer: 6 (9%)
• Sold later, at a premium: 4 (6%)
• Died after the hack: 14 (20%)
• Survived the hack, closed later: 10 (14%)

In total, 24 of 69 are gone, about one in three.

Survived on their own (35)

Bybit lost $1.46B in February 2025 and never stopped withdrawals. Partner loans and deposits refilled its reserves within 72 hours. KuCoin lost $281M in 2020, had BTC and ETH withdrawals back in 11 days and covered the last $45.6M from its insurance fund. Bitfinex went the hard way: after its 2016 hack it cut every balance by 36%, issued tokens for the loss and bought all of them back at $1 within 8 months.

Rescued by a buyer (6)

Coincheck lost $530M in 2018, paid clients back from its own capital and was sold to Monex 70 days later for $33.5M, about 6% of the loss. Zaif went to Fisco, and DMM Bitcoin's accounts went to SBI. On median, a buyer showed up 2.6 months after the hack. A rescue is no guarantee: Liquid needed a $120M loan from FTX and died with it, and two smaller rescues collapsed under their buyers.

Sold later, at a premium (4)

A hack does not always mark the top of the risk. Deribit lost $28M in 2022, and Coinbase later bought it for $2.9B, 104x the hack. Bitstamp lost $5.3M in 2015, and Robinhood paid about $224M for it. Upbit, hacked for $49M in 2019, has a pending deal with Naver.

Died after the hack (14)

Mt. Gox, BitGrail, Cryptopia and Lykke are the best known. The dead were mostly small: their median hack was $6.5M, against $26M for exchanges that survived. Of the 25 exchanges that lost $40M or more, only Mt. Gox and BitGrail died right after. Below $40M, 12 of 44 did. Dollar size here is a proxy for exchange size, so read it as a pattern, not a law.

Survived, then closed (10)

BitMart, CoinEx, EXMO, AscendEX and NoOnes all got through their hacks, then announced closures between July and September 2026. Only EXMO partly tied the decision to its hack.

The clock

We checked withdrawal reopening dates in 20 cases. Exchanges that survived had withdrawals back in a median of 5 days, and 11 of 13 reopened within three weeks. Bybit, Crypto.com and Deribit took less than a day. Mt. Gox, Cryptopia and Lykke never reopened. All three died.

Who paid matters as much. In 12 of 21 cases the exchange covered the loss itself from reserves, SAFU or an insurance fund. Four relied on loans or outside money, two cut client balances, and in three cases nobody paid. All three of those died.

Binance: survivor territory

Binance lost $6.36B on October 29, about 3.7% of its $171B in reserves. It replaced 95% of the stolen amount from SAFU, its insurance fund and treasury, and reopened withdrawals 2.4 days after the drain started. On every measure we tracked, that sits inside the survivor range.

Mercado Bitcoin: the number to watch

Mercado Bitcoin, founded in 2013, serves 4.5M clients. The main drain took about 34 minutes across roughly 10 chains, through ordinary signed transfers rather than a smart contract bug. MB says the incident is contained, with no harm to clients and no data leak, and Tether froze 4.5M USDT.

MB applied for its new Brazilian central bank licence on October 27, six days before the hack. The rules already required an incident response plan, and nothing in them says a hack costs a licence.

Deposits and withdrawals are still paused, with no reopening date. History says that date is the clearest early signal of how this ends.

The Hyperliquid-based perpetuals venue for stocks and commodities detected unauthorized activity affecting its GitBook documentation on Monday morning. The docs were restored to their previous state as of 9:15 AM ET.

As a precaution, users are advised not to click any links inside the documentation while the investigation continues. The team has not disclosed what was altered or whether any user funds were affected.

Compromised documentation pages are a common phishing vector, where attackers swap legitimate links for wallet drainers. Further updates are expected as the review progresses.

The bitcoin treasury company made the purchases between Oct. 24 and Oct. 30, as disclosed in a Monday filing with the SEC. The buy is a slowdown after Strive picked up around $1.25 billion of BTC in October alone.

Strive now holds 43,124 BTC and ranks fourth among public companies, behind Strategy (849,327 BTC), Metaplanet (44,000 BTC) and Twenty One (43,514 BTC).

CEO Matt Cole has set a goal of becoming the second-largest public bitcoin holder by year-end. At current holdings, Strive would need fewer than 100 BTC per week for the rest of 2026 to overtake Metaplanet, assuming the Japanese company stops buying.

Most of the latest purchases were funded with existing cash, and Strive also tapped its $1 billion SATS preferred stock at-the-market program for the first time. The company ended Oct. 30 with $490.4 million in cash and equivalents, down $14 million in a week.
