Adshares Bridge (ADS)
Summary
Adshares is a blockchain-based advertising protocol whose cross-chain bridge was exploited on May 17, 2026, for approximately $628,000 via a bridge verification bypass. The attacker minted unbacked wrapped ADS (wADS) on Ethereum by submitting three wrapTo() calls referencing non-existent native-chain transaction IDs, then liquidated the fake tokens through Uniswap V4, draining ETH and USDC from liquidity pools. Following an on-chain bounty offer from the project, the attacker returned 256 ETH (approximately $540,700, representing roughly 86% of stolen funds) to the deployer address.
