bridge

Garden Finance is a cross-chain Bitcoin bridge protocol launched in 2023 by former Ren Protocol developers, using Hash Time Locked Contracts (HTLCs) and an intents-based solver network to enable atomic swaps across Ethereum, Solana, Arbitrum, Base, and other chains. On October 30–31, 2025, one of its largest solver operators was compromised via a leaked private key, resulting in approximately $11.4 million in stolen assets that were subsequently laundered through Tornado Cash. Prior to the exploit, blockchain investigator ZachXBT alleged that over 80% of the protocol's recent fee revenue was derived from laundering funds stolen in the February 2025 Bybit hack, which the Lazarus Group (DPRK) perpetrated for approximately $1.4 billion.

Across Protocol is a cross-chain bridge protocol built on UMA's optimistic oracle, founded by Hart Lambur and the UMA/Risk Labs team and launched in 2021. In June 2025, pseudonymous investigator Ogle alleged that protocol insiders used undisclosed wallets to push through two governance proposals transferring approximately 150 million ACX tokens ($23 million) from the DAO treasury to Risk Labs, the team's own organization, constituting alleged self-dealing and DAO manipulation. Separate allegations from LayerZero founder Bryan Pellegrino claimed insider trading preceded a surprise Binance listing of ACX in December 2024, with the protocol subsequently proposing in early 2026 to dissolve its DAO entirely and convert to a U.S. C-corporation.
