Omen review

Omen is the Gnosis-based prediction-market interface GammaPredict keeps as a flagship on-chain reference. It is how a large part of crypto still pictures “decentralized event markets”: create a question, post liquidity, resolve via an oracle, settle on-chain.

That is a different product from Polymarket’s retail board. Treat Omen as infrastructure-plus-UI, not as a 2026 liquidity leader. We do not claim a funded live-test of every Omen market.

Pros

  • Canonical Gnosis / conditional-token interface in this directory
  • Wallet-first, on-chain settlement you can inspect
  • Useful history for how crypto prediction markets were supposed to work

Cons

  • Liquidity is not Polymarket’s homepage board
  • Oracle and UX friction are real
  • Not a US CFTC DCM and not a UKGC book
  • Front-ends and chain details can move

Interface

Presagio public Omen-derived prediction interface
Presagio public prediction interface; Gnosis describes it as an active Omen-derived frontend. omen.eth.limo did not finish for this desk.

A second capture of presagio.eth.limo returned an IPFS “Content Unreachable” page; docs.gnosis.io/omen returned 404. We do not publish those errors. The figure above remains the last usable Presagio/Omen-derived public UI.

Expect a list of open questions, probabilities, category filters and a connect-wallet control. Creating a market is closer to the surface than on Kalshi. The UI is functional rather than a news terminal. Confirm you are on the official front-end before you sign anything.

Markets

Crypto, politics and economy questions the community actually seeds with liquidity. Empty markets are a feature of permissionless creation. If the book is decorative, skip it.

Access, KYC and region

Wallet on Gnosis (confirm the live chain). Default posture is wallet KYC, not a bank onboarding. Thresholds and front-ends can still add checks. Geo-policy still exists.

  1. Open the official Omen front-end from our visit hop.
  2. Connect a wallet on the stated chain.
  3. Do not use a lookalike app from a search ad.

How to place a trade

Buy outcome tokens / add liquidity as the live UI presents it. This is not a sports slip.

  1. Read the question and the oracle/resolution path.
  2. Check whether anyone else is in the book.
  3. Size for gas plus the chance you cannot exit.
  4. Sign and verify the position on-chain.

Fees, rails and funding

Network fees plus any trading/LP fee the UI shows. Self-custody: lost keys are lost funds. GammaPredict never holds keys.

  1. Bridge or buy the listed asset on the correct chain.
  2. Send a test amount.
  3. Place one tiny trade, then try an exit.

Risks and limits

Oracle disputes, thin books, outdated front-ends, and treating Omen as if it had Polymarket’s volume. Smart-contract risk is not a slogan.

Verdict

Use Omen when you want Gnosis-style on-chain markets. Use Polymarket for retail event discovery. Use Azuro for sports liquidity. Use Kalshi when you need a US DCM.
