What this game is
FWA (Fake World Assets) by TokenWorks is an Ethereum NFT-gacha pool. Depositors list an ERC-721 plus ETH backing that both funds a standing sellback bid and sets the listing selection weight inversely (lightly-backed listings are drawn more often). Purchasers pay an expected-value-priced fee for a Chainlink VRF draw that allocates one listing, then either keep the NFT or sell it back for a discounted slice of its backing. The structural house edge comes from that sellback discount plus a protocol surcharge, making each pull negative expected value by design.

Published risk audit
Elevated overall risk · 13 findings
# FWA structural risk audit v1 — executive summary FWA is a mechanically well-built, non-proxy NFT-gacha system (solc 0.8.30, Chainlink VRF v2.5, Solady primitives, consistent CEI + reentrancy guards, per-listing ETH escrow keeping the core pool solvent, immutable purchaser-payout floors). No critical exploitable code bug was found. The dominant risk is trust concentration, not an exploit: a single owner key controls every economic knob across all 8 contracts (uncapped surcharge, owner-mutable VRF coordinator, rewards/ airdrop drains behind state guards, a 1-year Splitter sweep, merkle-root reset), with no timelock and unverified multisig. On a negative-EV gambling game, a fair-but-house-favored machine whose parameters the house can retune at will is the defining structural risk. Overall risk: elevated. Grade: C. Independent analysis — not a formal audit, not an endorsement, no buy/sell advice. Full report: docs/audits/fwa/audit-v1.md.
