According to an official disclosure by Hyperbridge, the losses from the Token Gateway vulnerability incident on April 13 have been revised upward from an initial estimate of $237,000 to approximately $2.5 million. The increase stems primarily from losses incurred in incentive pools on Ethereum, Base, BNB Chain, and Arbitrum. The attacker extracted roughly 245 ETH from related contracts, then bypassed the MMR proof verification mechanism by forging cross-chain messages, minting 1 billion bridged DOT tokens and dumping them onto illiquid markets. Currently, some of the stolen funds have been traced on-chain to Binance. Hyperbridge is collaborating with Binance’s compliance team and law enforcement agencies to investigate the incident. Polkadot-native DOT and products such as Intent Gateway remain unaffected. The Token Gateway and bridged DOT contracts on the four affected EVM chains remain suspended. An external audit of the patched MMR verification logic is underway, and bridging functionality will be restored upon completion of the audit.
Odaily News Ripple announced a partnership with South Korea's major insurance institution, Kyobo Life Insurance, to explore government bond tokenization settlement based on the Ripple Custody platform. The goal is to compress the T+2 settlement cycle for South Korean government bonds to near real-time execution. Both parties stated that they will focus on evaluating the technical and regulatory feasibility of tokenized government bond settlement. Specific transaction scale, launch timeline, and bond types involved have not been disclosed yet, and the overall initiative is still in the pilot exploration phase. Additionally, Kyobo Life will also explore stablecoin-based payment solutions, but specific currencies and implementation timelines have not been clarified. (CoinDesk)
According to Cointelegraph, the blockchain payment network XRP Ledger (XRPL) has partnered with zero-knowledge infrastructure provider Boundless to integrate its zero-knowledge technology into the underlying network, aiming to enable confidential and compliant on-chain transactions for banks and asset management firms. Shiv Shankar, CEO of Boundless, stated that the solution protects sensitive information—including transaction size, frequency, and counterparty details—through selective disclosure and role-based access control, while ensuring regulatory authorities can audit related activities. This integration is expected to drive adoption across multiple institutional use cases on public blockchains, including cross-border corporate payments, treasury management, over-the-counter (OTC) trading, tokenized asset issuance, and decentralized finance (DeFi). Industry observers believe that striking a balance between privacy and compliance is becoming a key factor in driving institutional adoption of public blockchains.
Decentralized GPU cloud computing infrastructure platform Aethir confirmed that its Ethereum-related bridge contract was attacked. The team promptly disconnected the affected contract and, in collaboration with major exchanges, blacklisted the hacker’s wallet, limiting losses to under $90,000. Earlier, blockchain security firm PeckShield estimated losses at $400,000. The attacker exploited Aethir’s cross-chain smart contract, AethirOFTAdapter, to transfer stolen funds from BNB Chain to Tron. Aethir stated that its Ethereum mainnet ATH token supply remains unaffected. It plans to release a detailed compensation plan and incident analysis next week and will collaborate with exchanges including Binance, Upbit, and Bithumb to freeze funds. Web3 security platform ZeroShadow is assisting with the investigation. In 2025, Aethir achieved $127.8 million in revenue and deployed over 440,000 GPU containers globally.
U.S. law firm Gibbs Mura has launched a class-action litigation investigation into the April 1, 2026, hack of Drift Protocol, reviewing potential investor claims against Circle Internet Financial. The attack resulted in the theft of approximately $280–285 million in assets. The attacker subsequently used Circle’s Cross-Chain Transfer Protocol (CCTP) to bridge over $230 million worth of USDC to Ethereum—Circle took no action to freeze the funds throughout the incident. Notably, just nine days prior, Circle had voluntarily frozen 16 business wallets in a separate civil dispute. Blockchain analytics firm Elliptic suspects the attack was carried out by a North Korea–backed hacking group. As a result of the breach, Drift Protocol’s total value locked (TVL) plummeted from $550 million to below $250 million, the DRIFT token price dropped more than 40%, and at least 20 DeFi protocols suffered indirect losses.
