Reputation you can carry with you
PredictStamp records every realized forecast — including early exits before an event ends — and commits a daily cryptographic ledger to Base. Not hype. Not likes. Judgment, signed.
Why this matters
Trust should not live inside a walled garden
Most platforms ask you to trust their database. A score on a screen, controlled by an operator, revocable without explanation. That works for entertainment — not for credibility.
EAS (Ethereum Attestation Service) is a public-good protocol: anyone can make signed statements about anything, in a standard format other apps and AI agents can verify without calling PredictStamp.
“The value of an attestation comes from who makes the claim — and whether anyone can independently check that the claim existed, unchanged, at a point in time.”
Adapted from the EAS ethos — portable proofs over platform lock-in.
- Your track record is a chain of signed events, not a hidden formula.
- Other ecosystems can read the same proofs — wallets, agents, marketplaces.
- Resolved and exited forecasts are immutable. History cannot be quietly rewritten.
Before the event ends
Exit early, keep the record
When you close a forecast before the market resolves, reputation is realized immediately from odds movement — the same mark-to-market logic as Polymarket-style P&L. The event may still be open; your points are not pending.
Every daily batch includes these exits alongside resolved forecasts. Entry snapshot, exit snapshot, points delta — whether the world has moved on or not.
Example
Forecast Yes at 40% market odds. Exit at 55% before resolution.

Architecture
One batch per day
We do not spam the chain with every click. Once every 24 hours, PredictStamp bundles every realized position into a Merkle tree and anchors the root on Base.
-
1
You act
Enter a market, exit early, or hold to resolution. Reputation changes only when the position closes.
-
2
We sign
Each event gets an off-chain attestation instantly — no wallet required from you.
-
3
We batch
Leaves = entry + close + points. Hashed into a Merkle root for the rolling 24h window.
-
4
Base anchors
One transaction commits the root. Anyone verifies a row with a Merkle proof — pennies per day.

Build the record worth attesting to
Every forecast is practice. Every exit and resolution becomes durable proof of judgment.
