Introduction

TheBlockCade is a decentralized arcade platform on Stellar/Soroban: provably-fair on-chain games, prize pools, quests, leaderboards and tournaments.

stellarcade-sdk is the TypeScript client for it. One StellarCadeClient gives you:

• client.games — list games, commit to a round, play, fetch results
• client.prizes — prize pool state and claims
• client.quests — quest progress and claims
• client.leaderboard — global and per-game rankings
• client.tournaments — list, enter, track tournaments
• Wallet connectors (Freighter today, more via contrib/) that never see or hold a private key inside the SDK process
• verifyProof() — check any settled round's fairness proof yourself, offline, without trusting our API

Why fairness verification is the headline feature

Every game round is settled by stellarcade-arbiter using a commit-reveal scheme: it commits to a hashed server seed before accepting any bet, then reveals the seed after the round to derive the outcome. The SDK's verifyProof() recomputes that hash and the derived outcome from the published proof alone — see Fairness Verification.

If a proof doesn't verify, something is wrong, and you don't need us to tell you that.
