Hackathon Judge Reproducer Commands

Run these one-liners directly in your terminal using Foundry cast to verify contract state on Shannon.

1. Inspect Duel #1 on Shannon

Verifies duel state: Alice vs Bob stakes, market address, and settled flag.

cast call 0xc160f68e5f2e6846057ad6d4ada5d320b385c2cb "getDuel(uint256)((address,uint128,uint8,bool,address,uint128,address,uint64,address,uint16))" 1 --rpc-url https://api.infra.testnet.somnia.network

2. Verify Zero-Click Settlement by Precompile

Inspect the DuelSettled event showing viaReactivity=true, called by 0x00..0100.

cast logs --address 0xc160f68e5f2e6846057ad6d4ada5d320b385c2cb "DuelSettled(uint256,address,uint8,uint256,bool,bool)" --from-block 477711000 --rpc-url https://api.infra.testnet.somnia.network

3. Read Aggregate On-Chain Volume

Query total USDso volume escrowed and settled by Wagr on Shannon.

cast call 0xc160f68e5f2e6846057ad6d4ada5d320b385c2cb "totalWagered()(uint256)" --rpc-url https://api.infra.testnet.somnia.network
