| SC_CODE | string | "/* SapRoulette.dvm — P2 house-banked roulette (family B), single-zero wheel. Reuses the SapHouseDice operator-bankroll tier (CASINO_SPEC §18.3): - operator sets `floor`, funds real DERO via FundBank, withdraws profit but never below floor. - player picks a bet TYPE + amount; one RANDOM(37) spin (0..36) resolves atomically vs the bank. - house edge = single zero (0) pays nothing on all outside bets. Rake routed to collector every spin. Bet types: 0 Red (18 red) even money win 2*stake 1 Black (18 black) even money win 2*stake 2 Odd even money win 2*stake 3 Even even money win 2*stake 4 Low (1-18) even money win 2*stake 5 High (19-36) even money win 2*stake 6/7/8 Column 1/2/3 2:1 win 3*stake 9/10/11 Dozen 1/2/3 2:1 win 3*stake 12 Straight (num 0..36) 35:1 win 36*stake Zero (0): loses outside; straight bet on 0 wins.

Prove Transaction
Prove that you sent DERO in this transaction. Obtain proof using the dero-wallet-cli command or from your wallet statement.
Note: The proof is sent to the server for verification calculations.
Payload proofs are user-provided display proofs; for the strongest verification, confirm with the receiving wallet.
