Syscoin bridge validation waka allow make 5 billion SYS dem mint without permission

Syscoin don reveal say dem get wata problem for validation of dia cross-chain bridge wey allow manipulated transaction proofs pass dia proof-verification logic. For the UTXO bridge relay path, the bridge wrong accept or interpret the proofs, make e possible for unauthorised minting of about 5 billion SYS. Syscoin talk say no private keys been compromise. Dem trace the issue to validation failure for the bridge relay’s proof verification, and the team pause the bridge, find the affected validation path, and dem dey roll out fix after security review. The attacker reportedly split the tainted funds into two addresses wey hold about 4B SYS and 1B SYS, with the unauthorised amount valued about $8M at the time. Market data wey the report mention talk say SYS fall more than 40% (from about $0.0022 to near $0.0016). Broader context: DeFiLlama data link bridge exploits to losses pass $3.24B, about 42% of total DeFi hacked value. For SYS traders, dis na supply-integrity risk wey get to do with interoperability/bridge verification logic, no be key theft matter. Even with the bridge paused, market sentiment fit remain fragile and short-term volatility likely as markets reprice smart-bridge and cross-chain tail risk.
