Babylon Labs has initiated a temperature check proposal in the Aave community, proposing to integrate native Bitcoin as collateral on Aave V4 through the Babylon Trustless Bitcoin Vaults protocol.This solution does not require wrapping, cross-chain bridges, or custodians. Users will lock Bitcoin in Taproot UTXOs, and redemptions will be controlled by on-chain rules (such as loan repayments), settling directly to Bitcoin UTXOs. The proposal deploys two Aave V4 Spokes: Babylon Core Lending Spoke (lending) and BTC Vault Swap Spoke (post-liquidation settlement).Collateral exists in the form of vaultBTC, a transfer-restricted ERC-20 token that can only be transferred between fixed whitelisted addresses. In the liquidation process, liquidators can immediately settle with WBTC, and subsequent Bitcoin redemptions will be completed by arbitrageurs.

Toncoin announced that its bridge-v3 cross-chain bridge is scheduled to officially and permanently close on September 1, 2026. During the transition period before the closure, all proportionally charged cross-chain fees have been canceled, and users who have used the bridge are reminded to check their wallets as soon as possible and complete the withdrawal of any unprocessed or unrecovered assets before the deadline.If you hold Wrapped TON in Ethereum or BNB Smart Chain, you should rebridge to the TON network before the deadline. If you hold tokens such as jUSDT, jUSDC, jDAI, jWBTC, etc., you need to bridge back to the Ethereum network. Users must complete all asset migrations before the deadline to avoid assets being unable to operate across chains. After September 1, the cross-chain bridge will stop all transfer functions.

Uniswap's governance proposal aims to extend the protocol fee collection and burning infrastructure to BNB Chain and Polygon, and to complete the fee activation process on Celo that was not executed due to a configuration error.The proposal includes: setting the fee receiving address for the V2 protocol on BNB Chain, Polygon, and Celo to TokenJar, and designating the V3 Factory owner on the relevant chains as V3OpenFeeAdapter; additionally, Celo will transfer the feeToSetter role and V4 PoolManager ownership to CrossChainAccount.The proposal states that fees from each chain will be aggregated into the corresponding TokenJar, and then UNI will be bridged back to the Ethereum mainnet and sent to the burn address.

The cross-chain infrastructure platform Squid has completed a $6 million strategic financing round, led by North Island Ventures, with participation from Ripple, Dialectic, Borderless, and others.It is reported that Squid was initially incubated within the Axelar ecosystem and later developed into an independent platform. Since its launch in 2023, Squid claims to have processed over $6 billion in cross-chain transaction volume, covering more than 100 blockchains, with a total of over 4 million transactions and more than 1 million users. After this round of financing, Squid's total funding amount has reached $13.5 million. The company plans to use the new funds to launch new consumer-facing products, further simplifying the process for users to access, manage, and use crypto assets across chains.

The cross-chain network Everclear officially announced on social media that it has decided to end the operations of the Everclear Foundation and Labs, and to stop product development. Currently, the protocol has been shut down, and the Everclear UI and chain have ceased operation. The team stated that the remaining TVL in the protocol has been fully withdrawn, and to their knowledge, no user funds are trapped.Regarding the reasons for the shutdown, Everclear stated that although the monthly trading volume had previously reached $500 million, the team failed to establish sufficient commercial depth and convert it into effective revenue due to users' high price sensitivity in the cross-chain solver field. Additionally, the team exhausted its funds (runway) during the transition to a B2B2C model over the past six months, and several acquisition proposals explored were also unsuccessful.For future arrangements, Everclear is conducting an orderly liquidation to address outstanding debts. The team stated that if there are remaining funds after the debts are settled, they will explore repurchasing existing tokens, with a potential total repurchase amount estimated between $50,000 and $200,000, but this has not yet been finalized. Furthermore, the foundation is considering open-sourcing the protocol's intellectual property (IP) to give the DAO the option to continue advancing work under new management; currently, the DAO itself is still operational.

Syndicate Labs, Everclear, and ZERO Network announced the cessation of operations on the same day, highlighting the deep dilemmas in the blockchain infrastructure sector.Syndicate Labs, a startup supported by a16z and having raised over $27 million, announced its closure after five years of operation, stating that EVM Rollup is no longer the industry standard and the market has fundamentally shifted to custom chains. The cross-chain settlement protocol Everclear (formerly Connext) announced hours later that it would shut down its foundation and lab entities, despite having a monthly trading volume that once reached $500 million, it was unable to convert that volume into revenue, and the CLEAR token dropped about 40% on the same day. The gasless Ethereum Layer 2 ZERO Network built by the crypto wallet Zerion also announced its closure on the same day, with the team shifting focus to the development of Zerion wallet and API products, and users must bridge their funds out by July 31.The common dilemma faced by the three projects is that even with venture capital funding and operational products, it remains difficult to find a sustainable business model to withstand market deterioration.

According to on-chain analyst PeckShield (@PeckShieldAlert), the attacker of the VerusCoin cross-chain bridge has returned 4,052.4 ETH (approximately $8.5 million) to the project team's address (0xF9AB...C1A74), which accounts for 75% of the total stolen amount. The remaining 25% (1,350 ETH, approximately $2.8 million) is retained in the attacker's wallet as a white hat bounty.

According to on-chain analyst PeckShield (@PeckShieldAlert), the VerusCoin cross-chain bridge attacker has returned 4,052.4 ETH (approximately 8.5 million USD) to the project team's address (0xF9AB...C1A74), accounting for 75% of the total stolen amount. The remaining 25% (1,350 ETH, approximately 2.8 million USD) is retained in the attacker's wallet as a white hat bounty.

According to Blockaid monitoring, the Map Protocol/Butter Network cross-chain bridge has been attacked on Ethereum and BSC. The attacker tricked the Butter Bridge V3.1 contract into directly minting approximately 100 trillion MAPO tokens to a newly created EOA address, which is about 480 million times the legitimate supply of 208 million tokens. Additionally, according to DeFi community YAM monitoring, the attacker has currently profited approximately 52.2 ETH (about $110,000). In response, MAP Protocol stated that the team is aware of the situation and is coordinating with external security partners to investigate and contain the issue. The bridging between MAPO ERC-20 and MAPO mainnet has been suspended. Please do not trade MAPO ERC-20 tokens on Uniswap at this time. During the event mitigation period, the liquidity pool remains at risk.Butter Network responded that ButterSwap has been suspended, and the team is coordinating with external security partners for the investigation. Pending transactions will be processed after security is restored. User funds are not at risk, and all affected transactions will be fully processed after recovery.

The TON Network expansion project TAC has disclosed that a security incident occurred with the TON-TAC asset bridge on May 11. Four days later, approximately 80% of the affected assets have been returned. TAC today released a post-incident analysis report detailing the events. The root cause of the vulnerability was a lack of a single verification in the sorter software: the attacker deployed a counterfeit Jetton wallet on TON, and the sorter accepted the counterfeit tokens because it did not verify the code hash of the sender's wallet. The total loss was approximately $2.86 million, involving USDT, BLUM, and tsTON. Following a public appeal, about 90% of the assets were returned to the multi-signature address controlled by TAC on May 14, with the remaining 10% retained by the attacker.The cross-chain bridge remains paused, awaiting independent review of the repaired sorter software by the auditing party and TON partners. Cross-chain operations will resume once the verification of the repaired software is completed and the gap is filled with recovered assets and TAC Foundation token reserves. Due to the need for multi-party coordination, a precise timeline cannot be provided. The remaining funding gap will be filled by the TAC Foundation treasury, ensuring that users and protocols incur no financial losses. TAC reminds users that official updates are only published through this account and Telegram, and any unsolicited "recovery" or "support" private messages are scams.

The DeFi lending protocol Alchemix announced the completion of its cross-chain infrastructure update. The old alUSD / alETH cross-chain bridge on Optimism and Arbitrum has officially been taken offline and replaced with a new cross-chain bridge compatible with v3 alchemist.Alchemix disclosed that it has synchronized the DVN (cross-chain transaction validation) configuration, maintaining a 2/3 multi-signature confirmation mechanism for cross-chain transactions, while introducing Deutsche Telekom as a validation service provider to enhance the reliability of the cross-chain validation infrastructure.

Echo Protocol announced that it is investigating a security incident affecting the Echo cross-chain bridge on Monad. During the investigation, all cross-chain transactions remain suspended.According to previous reports, market news indicated that Echo Protocol was hacked on Monad. The attacker minted 1,000 eBTC (approximately $76.7 million) and used a tested process to deposit 45 eBTC (approximately $34.5 million) into Curvance. Subsequently, they borrowed approximately 11.29 WBTC (approximately $867,700) using this as collateral, bridged the WBTC to Ethereum, exchanged it for ETH, and ultimately transferred 384 ETH (approximately $821,700) to Tornado Cash.Yuxian, the founder of Slow Mist, stated that Echo Protocol may have been compromised due to the Admin single point private key being breached.

According to monitoring by Paitun, the Adshares cross-chain bridge attacker has returned 256 ETH to the project deployer's address, worth approximately $540,700, accounting for about 86% of the previously stolen funds.Previously, the Adshares cross-chain bridge was attacked on May 17, 2026, resulting in a loss of approximately $628,000.

PeckShield posted on platform X that from February to mid-May 2026, there have been at least 8 significant security incidents related to cross-chain bridges in the crypto industry, with attackers stealing approximately $328.6 million in assets from cross-chain protocols. PeckShield pointed out that cross-chain infrastructure remains a high-frequency target for hackers, and the associated risks continue to be highlighted in the context of the expansion of the multi-chain ecosystem.

Kelp announced on platform X that to ensure the security standards of rsETH and optimize network integration, cross-chain support for rsETH on multiple networks will be stopped after June 15. The affected networks include Optimism, Manta, Mode, Blast, Scroll, X Layer, zkSync, Zircuit, Swellchain, Hemi, Berachain, Sonic, HyperEVM, Unichain, TAC, Avalanche, Plasma Stable, MegaETH, Monad, and Movement.Kelp reminds users holding rsETH on the above chains that they need to bridge back to the Ethereum mainnet before June 15. After June 15, asset recovery can still be requested, but each address will need to pay a fee of 100 USDC. The specific process will be announced as the deadline approaches.

According to Blockaid monitoring, its vulnerability detection system found that the Verus Ethereum cross-chain bridge (verus.io) is under attack, resulting in approximately $11.58 million in losses.

Chainalysis posted on the X platform that before the theft of THORChain, wallets suspected to be associated with the attacker had been transferring funds through Monero, Hyperliquid, and THORChain for several weeks. The attacker-associated wallets had already deposited into Hyperliquid positions via the Hyperliquid and Monero privacy bridge as early as the end of April. The funds were then exchanged for USDC and transferred to Arbitrum, and later bridged to Ethereum, with some ETH subsequently transferred to THORChain to become staked RUNE for newly added nodes, which are believed to be the source of the attack.Afterward, the attacker bridged some RUNE back to Ethereum and split it into four pathways, one of which went directly to the attacker. After being transferred through intermediate wallets, 8 ETH was sent to the final wallet receiving the stolen funds 43 minutes before the attack. The funds from the other three pathways flowed in the opposite direction. These wallets bridged ETH back to Arbitrum, deposited it into Hyperliquid, and transferred it into Monero through the same privacy bridge, with the last transaction occurring less than 5 hours before the attack began.As of Friday afternoon, the stolen funds have not yet been used, but the attacker has demonstrated their skilled cross-chain money laundering capabilities, and the Hyperliquid to Monero path may become the next move.

According to CoinDesk, Kraken announced that it will use Chainlink's cross-chain interoperability protocol CCIP, replacing LayerZero as the exclusive cross-chain infrastructure for its wrapped assets, covering kBTC and more wrapped assets in the future. This migration involves over $3 billion in TVL, following a $292 million LayerZero-related cross-chain attack incident that occurred in April. Kraken stated that the migration will cover networks such as Ink, Ethereum, Unichain, and Optimism. kBTC is set to launch in 2024, with a current market value of approximately $260 million. Coinbase had previously also chosen Chainlink CCIP as the sole cross-chain bridge solution for about $7 billion in wrapped tokens.

Aave stated that the first batch of rsETH has been transferred to LayerZero's OFT adapter, and cross-chain operations for rsETH between the mainnet and various L2s have been reopened.This progress means that the previously affected rsETH cross-chain channels have been restored for use, covering the Ethereum mainnet and L2 networks.

The TAC team announced that its cross-chain layer's TON side was exploited by external attackers, resulting in a loss of approximately $2.8 million, involving USDT, BLUM, and tsTON. TAC, TON, and all ERC-20 tokens bridged from Ethereum are unaffected. The bridging service remains suspended, and forensic analysis and repair work are ongoing. A complete report with more details will be released within the next 48 hours.The team is actively collaborating with law enforcement, SEAL 911, and security partners to track and freeze the stolen funds. The team stated that its core focus is to sell the foundation's TAC token reserves in a legally structured manner to compensate for user losses and fully restore bridging liquidity. Official channels will continue to update progress.
