Trader exploits Multichain opening to turn $280,000 to $1.9 million; community suspects insider job
A wallet address turned nearly 1.9 million FTM worth $280,000 to $1.9 million within hours of exploiting the long-frozen Multichain bridge opening momentarily, leading to insider job speculations among the crypto community.
The Multichain bridge, frozen since its exploit in July 2023, opened briefly and closed again on Nov. 1. The trader seized the opportunity to make millions of dollars in profits.
Solana gains 80% in a month as Firedancer goes live on testnet
SOL has posted 30-day gains of nearly 81% and has rallied over 30% in the past week amid the testnet launch of the blockchain’s long-awaited scaling solution, Firedancer.
SOL reached over $41 on Nov. 2, touching highs it hasn’t seen since August 2022, Cointelegraph Markets Pro data shows. Long touted as an “Ethereum killer,” SOL has vastly outperformed its rival, Ether (ETH), which posted under 11% gains in the past month.
Avalanche blockchain explorer to shut down as Etherscan fees draw controversy
SnowTrace, a popular blockchain explorer tool for Avalanche, will shut down its website — powered by Etherscan’s explorer-as-a-service (EaaS) toolkit — on Nov. 30. The SnowTrace team clarified that only its Etherscan-powered explorer will be shut down.
According to the Oct. 30 announcement, Snowtrace users are required to save their backup information, such as private name tags and contact verification details, before Nov. 30. While the team did not explicitly state the reason for shutting down the explorer, some have pointed to Etherscan’s service fees for its EaaS toolkit. Mikko Ohtama, co-founder of Trading Strategy, claims that an annual subscription to EaaS can cost between $1 million and $2 million per year.
Nine protocols criticize LayerZero’s wstETH token, claiming it’s “proprietary”
A new bridged token from the cross-chain protocol LayerZero is drawing criticism from nine protocols throughout the Ethereum ecosystem. A joint statement from Connext, Chainsafe, Sygma, LiFi, Socket, Hashi, Across, Celer and Router on Oct. 27 called the token’s standard “a vendor-locked proprietary standard,” claiming that it limits the freedom of token issuers.
The protocols claimed in their joint statement that LayerZero’s new token is “a proprietary representation of wstETH to Avalanche, BNB Chain, and Scroll without support from the Lido DAO [decentralized autonomous organization],” which is created by “provider-specific systems […] fundamentally owned by the bridges that implement them.” As a result, it creates “systemic risks for projects that can be tough to quantify,” they stated. The protocols advocated for the use of the xERC-20 token standard for bridging stETH instead of using LayerZero’s new token.
Data from Cointelegraph Markets Pro and TradingView shows that DeFi’s top 100 tokens by market capitalization had a bullish week, with most tokens trading in green on the weekly charts. The total value locked into DeFi protocols jumped to $49.46 billion.

Trust Wallet, the self-custodial crypto wallet owned by Binance co-founder Changpeng “CZ” Zhao, has partnered with European fintech unicorn and digital banking giant Revolut to introduce a new way to purchase crypto assets on its platform.
Trust Wallet users can now buy Bitcoin (BTC), Ether (ETH) and Solana (SOL) with Revolut through a direct integration, the company announced on Thursday.
With a minimum purchase starting at 10 euros ($12) and capped at 23,000 euros ($26,950) daily and per transaction, Trust Wallet’s new buy option is expected to provide a faster and easier way to access crypto from Europe.
The integration will initially support only three crypto assets, but the companies said they expect to add stablecoins such as Circle’s USDC (USDC) at a later stage.
The feature enables zero-fee crypto purchases using multiple fiat currencies supported by Revolut, including the euro, the British pound, as well as the Czech koruna, Danish Krone, Polish Złoty and others.
While Revolut–Trust Wallet crypto purchases are offered with zero fees, adding money to a Revolut account is not free of charge in many cases, including via bank transfers, card top-ups and cash deposits. Cash deposits are subject to a 1.5% fee and are limited to $3,000 per calendar month, according to Revolut’s FAQs.
The integration came shortly after Revolut secured a $75 billion company valuation after completing a private share sale in late November. “This makes us Europe’s most valuable private company and in the top 10 of the world’s most valuable private companies,” Revolut said in a post on X.
CZ-backed Trust Wallet has been actively tapping into trending market sectors, including prediction markets and real-world asset tokenization, expanding access to these offerings for self-custody users.
Cointelegraph contacted Revolut and Trust Wallet for comment on the integration, but had not received a response by publication.
Doctors in England planning to go on strike in the run-up to Christmas are considering a new offer from the government to end the long-running dispute.
Resident doctors, formerly junior doctors, will walk out from 7am on 17 December until 7am on 22 December.
Health Secretary Wes Streeting has appealed to doctors to accept the government’s latest package.
The British Medical Association (BMA) said it will consult members by surveying them online on whether or not the deal from the government is enough to call off next week’s walkout.
The poll will close on Monday – just two days before the five-day strike is set to start.

The union said the new offer includes new legislation to ensure UK medical graduates are prioritised for speciality training roles.
It also includes an increase in the number of speciality training posts over the next three years – from 1,000 to 4,000 – with more to start in 2026.
Funding for mandatory Royal College examination and membership fees for resident doctors is also part of the deal.
It does not address resident doctors’ demand for a 26% salary rise over the next few years to make up for the erosion in their pay in real terms since 2008 – this is on top of a 28.9% increase they have had over the last three years.

Mr Streeting warned a resident doctors’ strike over Christmas would have a “much different degree of risk” than previous walkouts.
It coincides with pressures facing the NHS, with health chiefs raising concerns over a “tidal wave” of illness and a “very nasty strain of flu”.
A new strain of the flu virus is thought to be much more infectious than previous strains and has already led to a record number of patients needing urgent hospital care.
The union’s mandate to strike is set to expire shortly, but Mr Streeting has offered to extend it to allow the medics to take action later in January if they reject his offer.
He called the union’s decision not to take it up “inexplicable”.
Last week, NHS England chief executive Sir Jim Mackey branded the decision by doctors to strike as “something that feels cruel” and which is “calculated to cause mayhem at a time when the service is really pulling all the stops out to try and avoid that and keep people safe”.
BMA resident doctors committee chair Dr Jack Fletcher said the latest government offer “is the result of thousands of resident doctors showing that they are prepared to stand up for their profession and its future”.
“It should not have taken strike action, but make no mistake: it was strike action that got us this far,” he said.
“We have forced the government to recognise the scale of the problems and to respond with measures on training numbers and prioritisation.
“However, this offer does not increase the overall number of doctors working in England and does nothing to restore pay for doctors, which remains well within the government’s power to do.”
Polish lawmakers have doubled down on crypto regulation rejected by President Karol Nawrocki, deepening tensions between the president and Prime Minister Donald Tusk.
Polska2050, part of the ruling coalition in the Sejm — Poland’s lower house of parliament — reintroduced the extensive crypto bill on Tuesday, just days after Nawrocki vetoed an identical bill.
The bill’s backers, including Adam Gomoła — a member of Poland2050 — called Bill 2050 an “improved” successor to the vetoed Bill 1424, but government spokesman Adam Szłapka reportedly declared that “not even a comma” had been changed.
The division over Poland’s crypto bill comes amid the rollout of the European Union’s Markets in Crypto-Assets Regulation (MiCA) across member states ahead of a July 2026 compliance deadline for EU crypto businesses.
Critics say Bill 2050 is “exactly same bill”
The new version of Poland’s draft crypto bill provides an 84-page-long document that essentially replicates the original Bill 1424, aiming to designate the Polish Financial Supervision Authority as the country’s primary crypto asset market regulator.
He also mocked Tusk’s claim that the president’s earlier veto was tied to the alleged involvement of the “Russian mafia,” saying: “The bill is perfect, and anyone who thinks otherwise is funded by Putin.”
Government spokesman Szłapka reportedly claimed that Nawrocki will likely not veto the proposed bill this time, following a classified security briefing in parliament last week and “now has full knowledge” of the implications on national security.
The issue with MiCA: Local versus centralized EU oversight
Poland’s debate over its crypto bill sets an important precedent for implementing the EU-wide MiCA regulation, as the proposed legislation would place responsibility for market supervision on the local financial regulator.
The issue is particularly significant amid calls from some member states for more centralized MiCA supervision under the Paris-based European Securities and Markets Authority (ESMA).
In October, the Bank of France urged the EU to give the ESMA direct supervisory powers, warning that a fragmented approach to oversight could undermine the bloc’s financial sovereignty.
Notably, Polish economist Krzysztof Piech — a prominent critic of Poland’s proposed crypto bill — has questioned the need for the local legislation, noting that MiCA protections will take effect in 2026.
While local reports suggest that Nawrocki may not veto the bill this time, there is also speculation that his office has been presented with an “alternative” draft aimed at creating more favorable market conditions. The proposed alternative is reportedly designed to align with the EU-wide MiCA framework and remove direct oversight from the local regulator.
