Predge tracks Polymarket whales in real time and cryptographically signs every call. Traders get alerts. Agents get an API. Businesses license the proof. And anyone can verify it — offline, against a published key.
Real-time alerts when whales move on Polymarket. Wallet scores, a live terminal, and a free plan.
Get alerts →A pay-per-call API in USDC. No account, no key — the wallet is the customer. Plus an MCP server for your coding agent.
Read the docs →License our verified data, settle agent payments on our rail, or plug in a private feed.
Talk to us →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.
9f8e7d6c5b4a…d3c2b1a09We watch the wallets that move prediction markets — and score, sign, and serve what they do.
Every move from $5,000, pushed the moment it lands.
A provable skill score per wallet, plus a Heuristic Insider Watch.
Where resolved-outcome-scored wallets are actually betting — edge-based, not hype.
What's moving now and the largest single positions, live.
Consensus and daily reads sliced by market category.
Wallets ranked by a conservative, resolved-outcome win rate — not a lucky streak.
Tx-anchored Polymarket whale flow, each row an offline-verifiable attestation.
A signed record with a go / review / block tier a downstream system can gate on.
Beyond Polymarket: large prints on Kalshi markets — honestly labeled as anonymous institutional flow.
We track the whales that move Polymarket, wallet by wallet.
Every signal is scored and ed25519-signed against a published key.
Consume it as an alert, an API call, or an MCP tool.
Check any claim offline. No callback to Predge required — that's the point.
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.
Our signing key is public at /.well-known/predge-keys.json. Every signature checks against it, offline.
Calls are hash-chained; the chain head can be anchored to a public ledger, so even we can't rewrite the past.
Performance-staked signals: a bounded, pre-funded stake behind a call, forfeited if we're wrong. Not insurance — accountability.
License it, settle on it, or plug it into your product.
License our ed25519-signed, portable attestations and verified-outcome data. Your users verify offline — they don't take your word for it either.
Give your own API or agent platform an agent-native paywall. Accept machine payments in USDC over our settlement rail — in a day, not a quarter.
Bulk and private access to the full Polymarket whale dataset — beyond retail pay-per-call.
Every business offering is built on the same primitive as the rest of Predge: signed, hash-chained, offline-verifiable. Your customers can check the proof themselves.

Not for the API — the wallet pays per request. For alerts, just the Telegram bot.
Hit /verify?id=…, or recompute offline: sha256 the signed bytes, check it matches the content hash, verify the signature against our published key.
USDC on Base and Solana for the API; the facilitator rail also settles on a Bitcoin-L2.
No. Predge is verifiable market intelligence, not advice. You decide what to do with it.
Yes — that's the whole point. x402 payments plus an MCP server mean an agent discovers, pays, and verifies on its own.
The signature. Anyone can claim a call after the fact; we sign it before the outcome and let you check it.
