Act I: The Trust Crisis

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.

Act II: The Cryptographic Truth

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.

Games Arena

On-chain matches. Instant settlement.

Full Fairness Tool
How it works

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.

01

Commit

Before you bet, the server publishes sha256(serverSeed) — a commitment it can no longer change.

02

Play

Your round settles from serverSeed:clientSeed:nonce:ledgerHash — deterministic, not discretionary.

03

Verify

Recompute the hash yourself, offline, with the SDK or by hand. If it doesn't match, the round is provably invalid.

Autonomous Economics

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.

Telegram & Discord

Play without leaving chat.

The StellarCade bot links to your wallet the same way the web app does — a signature challenge, never custody.

01

Link your wallet

Sign a one-time challenge with your Stellar keypair. The bot never sees or holds your keys.

02

Play & check stats

Run rounds, check your balance and quest progress, right from the chat.

03

Claim on-chain

Claims settle through the same arbiter service and audit log as the web app — no separate, less-verifiable path.

Why StellarCade

Everything a fair arcade should be.

Provably fair

Every round settles from a commit-reveal proof you can verify yourself, offline — no trust in our servers required.

No custody, ever

Connect with Freighter. StellarCade never holds your keys or your funds.

Real prize pools

Payouts are enforced on-chain by Soroban smart contracts, not a database row.

Built for Stellar

Fast, low-fee settlement on Soroban — no waiting, no gas anxiety.

Leaderboards & tournaments

Compete on live leaderboards, or enter scheduled tournaments with pooled prizes.

Quests & badges

Daily and weekly quests earn XP and collectible badges tracked on your profile.

Telegram & Discord bot

Link your wallet once, then check stats and claim rewards straight from chat — no custody there either.

Audited settlement

Every payout writes to a hash-chained audit log; disputes resolve against that chain, not a support ticket.
