Polkadot was hit by a major exploit after 1 billion DOT tokens were unexpectedly minted. Blockchain security firm PeckShield flagged the abnormal issuance. The attacker then offloaded the full amount in one transaction. Lookonchain estimates the sale brought in about 108 ETH, valued at roughly $237K.

Arkham data show that FTX/Alameda Research on Tuesday unstaked and moved about $16 million worth of SOL to an address used for creditor distributions.

BlockSec's Phalcon team reported that a Merkle Mountain Range (MMR) proof replay weakness in Hyperbridge-managed HandlerV1 contracts on Ethereum led to losses of roughly $242,000. The issue stemmed from proofs not being tied to specific requests, enabling an attacker to reuse previously valid proofs alongside newly crafted requests to trigger sensitive operations, including administrator changes. In one instance, the attacker took over the administrator role for the Polkadot (DOT) token, then used the elevated privileges to mint additional DOT for profit. Transactions observed include administrator changes followed by minting DOT (about $237,400 lost) and ARGN (about $3,800 lost), as well as withdrawals from the host. BlockSec said the flaw was identified by PhalconSecurity and examined using PhalconExplorer. The disclosure follows earlier reports that a Hyperbridge gateway contract had been compromised, resulting in 1 billion DOT minted on Ethereum and later sold.

Uniswap's daily trading volume has climbed above $2 billion, marking its strongest showing in almost a year, The Block reported. The jump was largely fueled by renewed expectations that U.S. spot Ethereum ETFs could win approval, boosting overall trading activity. As one of the крупнейших decentralized exchanges in the Ethereum ecosystem, Uniswap's volume is widely watched as a barometer of market sentiment. Analysts say the platform's most active pairs remain ETH/USDC and ETH/USDT, as demand for stablecoin-based swaps continues to build.

Polkadot's $DOT briefly fell about 5% as traders reacted to an exploit involving Hyperbridge, a gateway used for bridged assets. The attacker allegedly forged cross-chain messages, seized an Ethereum-based $DOT admin role, minted 1 billion counterfeit $DOT, then sold the entire amount for roughly 108 ETH, netting an estimated $237,000. Polkadot's native chain was not compromised. The incident is reported to be confined to bridged tokens issued on Ethereum.

ALERT: Bridged $DOT on Ethereum has been exploited. An attacker minted 1B $DOT and sold the entire amount in a single transaction, receiving 108.2 $ETH (about $237K).

On April 13, Hyperbridge's cross-chain gateway contract on Ethereum was exploited, as flagged by CertiK and reported by BlockBeats. An attacker reportedly forged messages to gain administrative control over the bridged Polkadot (DOT) token contract, subsequently minting 1 billion fake DOT. These fraudulent tokens were then sold, generating approximately $237,000 in profit. The substantial sell pressure caused the token's price to plummet from $1.22 to near zero, with further liquidation hindered by thin on-chain liquidity. This incident specifically affected the bridged DOT asset on Ethereum, not the native Polkadot network. As of the report, neither Hyperbridge nor the Polkadot team has issued an official statement regarding the exploit.

Perpetual DEX trading terminal Genius, backed by YZi Labs, announced on April 13, according to Huo Xing Cai Jing, the introduction of a "refund" option for its airdrop program. This decision follows significant community feedback regarding token distribution. Under the updated policy, users can burn 100% of their GENIUS airdrop allocation within 48 hours of the Token Generation Event (TGE) to receive a refund of their net fees paid to the platform. Genius clarified that refunds are calculated on net fees, excluding over $7 million in trading rebates and $1.3 million in referral rewards already disbursed. The refund mechanism specifically applies to fees collected by Genius, not third-party protocols like PancakeSwap.

Aave DAO has officially approved the 'Aave Will Win' proposal, securing approximately 75% of votes in favor. This significant governance decision authorizes a substantial allocation of resources to Aave Labs, comprising a $25 million stablecoin grant and an additional 75,000 AAVE tokens. The initiative is strategically designed to bolster the Aave ecosystem, fostering accelerated growth and innovation within its decentralized finance (DeFi) protocols. This move, backed by a strong community consensus, aims to empower Aave Labs in its mission to drive future development, enhance protocol capabilities, and maintain Aave's competitive edge in the evolving Web3 landscape, reinforcing its position as a leading DeFi platform.
