Summary

SIR (Synthetics Implemented Right), operating as SIR.trading, is an Ethereum-based DeFi protocol offering non-liquidating leveraged tokens and synthetic assets. On March 30, 2025, just 39 days after its February 20 mainnet launch, the protocol's Vault contract was completely drained of its entire $355,000 TVL through an exploit targeting a novel misuse of Ethereum's transient storage (EIP-1153) introduced in the Dencun upgrade. The attacker laundered proceeds through Railgun; the founder publicly pleaded for a partial return of funds; the protocol subsequently relaunched after completing four additional security audits.
