Why Predge is different

Every call is signed before the outcome. So it can't be edited in hindsight.

Anyone can post a winning screenshot after the fact. Predge commits each call with an ed25519 signature while the market is still open, chains it to the previous call, and welds the settled outcome to the exact signed bytes. Tamper-evident by construction — and you never take our word for it.

EVIDENCE PACKVERIFIED
  • ed25519 signature is valid for the signed bytes
  • content hash equals sha256 of the exact signed bytes
  • settled outcome is welded to the claim
  • resolution signature is valid

We watch the wallets that move prediction markets — and score, sign, and serve what they do.

How it works

Index. Sign. Serve. Verify.

01

Index

We track the whales that move Polymarket, wallet by wallet.

02

Score & sign

Every signal is scored and ed25519-signed against a published key.

03

Serve

Consume it as an alert, an API call, or an MCP tool.

04

Verify

Check any claim offline. No callback to Predge required — that's the point.

Agent-native by design

Your agent pays per call. In USDC. No account, no API key.

Predge speaks x402: request a route, get a 402 with a price, pay in USDC, receive signed data. The wallet is the customer. 26 routes, settling on Base and Solana, a public OpenAPI, a free verifier, and an MCP server so any agent can buy data as a tool.

Don't trust — verify

You never take our word for it.

KEY

Published key

Our signing key is public at /.well-known/predge-keys.json. Every signature checks against it, offline.

CHAIN

Tamper-proof history

Calls are hash-chained; the chain head can be anchored to a public ledger, so even we can't rewrite the past.

STAKE

Skin in the game

Performance-staked signals: a bounded, pre-funded stake behind a call, forfeited if we're wrong. Not insurance — accountability.

Predge for business

The same verifiable intelligence — as infrastructure.

License it, settle on it, or plug it into your product.

Verified-data & attestation licensing

License our ed25519-signed, portable attestations and verified-outcome data. Your users verify offline — they don't take your word for it either.

  • Portable across venues
  • Independently verifiable, no callback
  • Live sports-attestation vertical in production
  • Plugs into agent-reputation systems

FAQ

Questions, answered.

Do I need an account?

Not for the API — the wallet pays per request. For alerts, just the Telegram bot.

How do I verify a call?

Hit /verify?id=…, or recompute offline: sha256 the signed bytes, check it matches the content hash, verify the signature against our published key.

What chains and currency?

USDC on Base and Solana for the API; the facilitator rail also settles on a Bitcoin-L2.

Is this financial advice?

No. Predge is verifiable market intelligence, not advice. You decide what to do with it.

Can an AI agent use this without a human?

Yes — that's the whole point. x402 payments plus an MCP server mean an agent discovers, pays, and verifies on its own.

How is this different from other "whale trackers"?

The signature. Anyone can claim a call after the fact; we sign it before the outcome and let you check it.
