Grade every market caller before kickoff. Sized with real edge.

Anyone can claim a winning streak after the final whistle. Tally seals every call on Sui mainnet before the start, anchors it into Walrus Memory, and holds every voice to mathematical proof.

The kickoff edge

Markets close. The cryptographic seal doesn't.

Every prediction commits a SHA-256 digest to Sui mainnet before the market locks. Tatum gRPC confirms the block checkpoint before kickoff, locking the time and price in stone.

When the market settles, Tally pulls the kickoff line. Callers who consistently beat the closing line print real mathematical profit. Those who don't get benched.

Mathematical sizing for voices with proven edge.

The size

A great call, sized for mathematical edge.

A voice with edge shouldn't bet the house, and a voice without edge shouldn't bet a cent. Tally runs half-Kelly sizing on every earned caller, capped at 2% of bankroll, so you harvest the edge without blowing up.

Built for verification

Ask anything. Inspect every receipt on chain.

Every call and grade archives into Walrus Memory as decentralized blobs. Anyone can query a voice's history using natural language, or verify the exact SHA-256 seal on Sui through Tatum gRPC.

Over 947 decentralized memories across 31 namespaces sit on Walrus right now. No deleted tweets, no edited spreadsheets, no post-game excuses. Just unalterable cryptographic truth.
