Security considerations

Time Validation

1. Primary Enforcement: Scrolls enforces trading deadlines at the transaction layer
2. Contract Validation: Timestamp passed in operation data is validated by the contract
3. Defense-in-Depth: Both layers provide security

Signature Verification

• Resolution Signatures: Uses Schnorr signatures (k256) for WASM compatibility
• Creator Signatures: Market creator can cancel markets with valid signature
• Oracle Proofs: Cross-chain oracle verification (simplified trusted oracle for Hackathon MVP). Migrating to verification via Reclaim Protocol.

Supply Limits

• Min Bet: Prevents dust attacks and ensures meaningful trades
• Max Supply: Bounds market size and prevents overflow
• Checked Arithmetic: All supply operations use checked arithmetic to prevent overflow
