When Cross-Chain Power Concentration Fails: Lessons from the $610M Poly Network Exploit On 10 August 2021 Poly Network suffered an exploit that resulted in roughly $610M being drained across Ethereum, BSC, and Polygon. The attacker abused assumptions in the cross-chain contract logic and leveraged those privileges to authorize large token movements across multiple chains. That incident exposed a common problem: when bridging logic or a single coordinator holds too much power, a single flaw can cascade into massive, multi-chain loss. Pactswap @Pact_Swap avoids that failure mode by making each swap a self-contained, enforceable commitment rather than routing value through one bridging contract or central coordinator. Execution is driven by per-swap rules, economic commitments (collateral), and event interpretation via Coinweb @CoinwebOfficial so misbehavior is economically constrained and scope-limited. In practice that means a contract bug or compromised component can only affect the specific collateral-backed pact involved, not the whole protocol, and the protocol’s rules will fail closed instead of allowing uncontrolled drains. @Pact_Swap GM everyone
