$ROULANA is the coin of Roulana: live multiplayer European roulette on Solana, played with real USDC at one 3D table. Every round with money on it is drawn and paid by a Solana program whose code is public and verified, and every bet can be checked. Half of the table's 1 % fee, paid by the bank out of its house edge, buys $ROULANA back in public. The creator's 7.5 % is locked on Jupiter Lock.
