The provably-fair arcade, on-chain
StellarCade is a decentralized arcade on Stellar/Soroban — games, prize pools, quests and tournaments, with every result independently verifiable.
Traditional gaming is rigged behind closed doors.
Conventional online platforms execute game wagers inside hidden databases. They promise random outcomes, but control the seed parameters, manipulate multipliers dynamically, and lock your deposits in centralized custodial accounts. You cannot inspect the math, and you cannot audit the server.
Decoupled on-chain entropy.
StellarCade forces complete transparency. The server publishes a SHA-256 hash of its secret seed before you commit your bet. Your browser mixes client-side seed parameters with the live, immutable hash of the Stellar ledger, executing the final outcome deterministically via audited Soroban smart contracts.
On-chain matches. Instant settlement.
Challenge the house or duel other players in real-time. Every match executes non-custodially via Soroban smart contracts.
Coinflip Duel
Instant cryptographic coinflip duel backed by SHA-256 commit-reveal entropy and Soroban smart contracts.
Verifiable Dice Roll
Roll against modular smart contract entropy with customizable prediction targets and real-time payout execution.
Prize Pool Gauntlet
Navigate escalating risk rounds to unlock accumulating community prize pool vaults and seasonal jackpot splits.
Audit any round in real-time
Don't take our word for it. StellarCade uses standard NIST-compliant SHA-256 WebCrypto functions you can execute right now in your browser.
Live Cryptographic Sandbox
Test real SHA-256 WebCrypto proof derivation directly in your browser.
Commit, reveal, verify.
Every round follows the same provably-fair scheme, checked client-side by @stellarcade/sdk — you never have to take our word for a result.
Commit
Before you bet, the server publishes sha256(serverSeed) — a commitment it can no longer change.
Play
Your round settles from serverSeed:clientSeed:nonce:ledgerHash — deterministic, not discretionary.
Verify
Recompute the hash yourself, offline, with the SDK or by hand. If it doesn't match, the round is provably invalid.
Transparent 2% vault allocation
Unlike traditional casinos, StellarCade fees route directly into autonomous, on-chain reward pools for the community.
98% direct winner return
98% of all match stakes are disbursed immediately to the winning player's wallet upon Soroban contract resolution.
70% of fee to weekly jackpot
The largest portion of protocol fees accumulates in the autonomous prize pool vault, distributed weekly to active tournament players.
30% of fee to quest treasury
Funds milestone rewards, Soulbound Badge minting, and leaderboard prizes for seasonal quest participants.
