Polymarket just lost $2.9M in a supply-chain attack — and it's paying every user back in full. The prediction platform confirmed unauthorized access through a third-party vendor, draining funds across multiple smart contracts. Full refunds are coming.

What makes this story stand out isn't the hack itself. Supply-chain attacks on crypto infrastructure are becoming disturbingly common. Third-party dependencies — wallets, oracles, bridge contracts — are the soft underbelly that no amount of smart-contract auditing can cover.

Polymarket's response is notable. Rather than hiding behind legal language or pointing fingers, the platform announced immediate full refunds for all affected users. No partial settlements, no negotiation. That level of accountability is rare in crypto.

For prediction markets and DeFi at large, this is a wake-up call. The attack vector wasn't Polymarket's own code — it was a vendor. Every protocol relying on external tools faces the same exposure.

Will radical transparency become the new standard for handling security breaches? Or is this a one-off gesture that won't survive the next crisis?
