Payy Network's Ethereum bridge drained of $1.83M USDC: what is confirmed
Payy says its Ethereum bridge contract was drained of its full balance and that the cause was not a compromised key, social engineering or its off-chain infrastructure. The root cause is still undisclosed, so here is what the public record supports and what bridge teams should check.
Meter's Bridge Mint Bug: $2.3M in Unbacked Tokens, an 88% Price Crash
A flawed validation check in Meter Passport let an attacker mint unbacked wrapped MTR and MTRG, dump them on a DEX, and crater both tokens — forcing the chain and bridge offline.
Blockstream Halts Liquid Network After $320M Exits via a 'Whitehat' Claim
A withdrawal equal to roughly 95% of Liquid Network's bitcoin reserves moved through a peg-out authorization key that Blockstream says was never compromised — a gap that matters more than the on-chain "whitehat" message left behind.
Wanchain Bridge Exploit Drains $9M in NIGHT Tokens: A Signature-Reuse Lesson
A flawed message-encoding scheme in Wanchain's Cardano–BNB bridge let an attacker reuse a legitimate signature to drain 515 million NIGHT tokens — a reminder that bridge validators, not the chains they connect, remain the weakest link.
Across Protocol's Solana Bridge Hit for $3.35M — Relayer, Not Users, Took the Loss
A July 17 attack on Across Protocol's Solana deployment drained roughly $3.35 million from the project's own relayer, not from bridge users — a result that says as much about bridge architecture as it does about the exploit itself.
