Hacker netted about $1.2M–$1.3M after hijacking Vlad Tenev’s X account to tout fake $VLAD token
A hacker took over Robinhood co-founder Vlad Tenev’s X account and spent about 40 minutes promoting a fake $VLAD memecoin as the token for Robinhood Chain, triggering a rush of buying that briefly pushed its market cap to nearly $10M. On-chain analysts estimate the attacker profited by dumping 650–690 ETH, worth about $1.2M–$1.3M. Robinhood has not confirmed the amount. The incident occurred as Robinhood Chain surpassed $700M in assets and reached 300,000 daily users.

REVA participants say Binance Wallet pre-TGE and eight Booster rounds left them out of pocket as token remains unreleased
REVA (@r3vl_xyz) ran a pre-TGE campaign on Binance Wallet in August 2025 and followed with eight Booster rounds, prompting users to commit BNB and pay gas fees. As of July 2026, its official Twitter account has stopped posting, the team is reportedly unreachable, and the token has yet to launch, leaving participants with out-of-pocket costs. One participant estimated their combined BNB and gas expenses at about 20U. There has been no refund, compensation, or official response.

On July 23, 2026, three major security incidents hit DeFi. An AFX-operated USDC custody bridge on Arbitrum was exploited for $24.15 million, prompting an emergency suspension of bridge operations.

Bitcoin-backed stablecoin Balance Coin (BLC) plunges over 99% after $912,000 oracle exploit
Balance Coin (BLC), a newly launched Bitcoin-collateralized stablecoin designed to hold a $1 peg, was hit by an oracle attack after an attacker submitted a falsely low BTC price. The manipulated price triggered liquidations across vaults, allowing the attacker to seize the BTC collateral and cash out about $912,000. BLC fell more than 99%, bottoming at $0.00075 and leaving its market value at about $2,570.

Poisoned dependency hijacks token A-linked agent runtime, attempt to drain full wallet blocked by Ledger rejection
A technical bulletin said an agent runtime tied to a crypto asset (Token A) was hijacked via a malicious dependency package that attempted to transfer out an entire wallet balance. The agent itself did not detect anything abnormal. The user’s Ledger hardware signer independently decoded the transaction and displayed the real recipient address and amount, prompting the user to reject the signature. No funds were moved.

Crypto platform halts trading after detecting $98,000 unauthorized withdrawal
A cryptocurrency trading platform said it detected an unauthorized $98,000 withdrawal from an ephemeral instance. The platform paused all trading, deposits and withdrawals as a precaution while it conducts an investigation expected to last several hours. It said user funds remain SAFU and that the platform will cover the loss so users are not affected. The incident did not involve the mainnet or a hot wallet, but the service halt disrupts immediate token liquidity and order execution across the platform.

Hacker exploited system loophole to buy Bitcoin for $5,000 and steal $23.7 million
A report with a French-language headline said a hacker tricked a system to execute Bitcoin trades at an unusually low price of just $5,000, stealing $23.7 million. The incident points to a failure in pricing and risk controls in crypto trading or settlement. The report did not specify the platform, on-chain details, or whether any funds were recovered. It involved a large, abnormal BTC fill and systemic fraud, dealing a direct blow to trust in the spot market.

Wanchain Cardano-side bridge lock address drained of ~515M NIGHT in 14:46–14:55 UTC window, leaving BNB wNIGHT largely unbacked
Between 14:46 and 14:55 UTC on July 22, 2026, Wanchain’s official bridge lock address on the Cardano side was drained, with about 515M NIGHT moved out—roughly 97% of the bridge’s 527M NIGHT reserves. The funds were routed through newly created wallets and more than 290M NIGHT were quickly sold on Cardano DEXs, sending the token down about 50%. Only NIGHT was affected and other bridged tokens were left untouched; on BNB, wNIGHT is now severely undercollateralized and redemptions are effectively broken.

Wanchain Cardano-to-BNB bridge incident disrupts bridged NIGHT token
An incident involving Wanchain’s Cardano-to-BNB cross-chain bridge has disrupted normal use of bridged NIGHT tokens. An official statement said the issue appears to stem from bridge operations rather than the Midnight Network mainnet itself. The team said it is monitoring the situation with relevant partners as it works to verify the facts. No loss amount, affected addresses, or recovery timeline has been disclosed, and users were urged to watch for phishing or impersonation scams.
