Trueo Overview
Trueo is an onchain prediction market on Base. You trade YES or NO tokens on crypto, politics, technology, business, and other real-world events. The winning token pays 1 TYD after the market resolves, while the losing token expires.
Trueo fits DeFi users, prediction traders, liquidity providers, and market creators who already use a Base wallet. To trade, deposit USDC and mint TYD, a yield-bearing collateral token. You can use TYD to buy outcome tokens, provide liquidity, or fund a new market. Open collateral keeps earning yield while the market remains active.
Each market uses Uniswap-style pools with a custom hook. Anyone can read the question, data sources, and resolution rules onchain before trading. An optimistic oracle handles the result, with a challenge period and dispute process if someone contests the outcome.
Trueo stands out through yield on open positions, fixed market rules, permissionless market creation, and noncustodial trading. It suits users who want binary markets on Base and prefer capital that keeps working while a prediction remains open.
Trueo Key features
-
Binary outcome markets
Trade YES or NO tokens on questions about crypto, politics, technology, business, and other real events. The winning token redeems for 1 TYD after resolution.
-
Yield bearing collateral
Deposit USDC and mint TYD, a vault token backed by USDC and powered by a Yearn strategy. TYD keeps earning yield while you hold open market positions.
-
Immutable market rules
The question, approved sources, and extra resolution rules are recorded on Base when a market launches. Anyone can check the original text on Basescan.
-
Permissionless market creation
Anyone can propose a new market through the funding launchpad. A proposal graduates when both sides receive enough TYD funding.
-
Onchain AMM trading
YES and NO tokens trade through Uniswap style pools on Base. A custom Uniswap v4 hook manages current markets, while users keep control of their tokens.
-
Permissionless token minting
Deposit 1 TYD to mint 1 YES token and 1 NO token. Before resolution, you can burn one of each token to recover 1 TYD.
-
Layered market resolution
Anyone can propose an outcome by posting a bond, and others have 12 hours to challenge it. Disputes can move to the Oracle Council, TRUE holders, and reputation-based attesters.
-
TRUE token governance
TRUE holders help govern protocol fees, oracle settings, branding, and dispute escalation. The token also provides economic weight in parts of the resolution process.
-
Market discovery tools
Browse markets by category, view live YES and NO odds, check volume, and save markets with bookmarks. The app includes crypto, politics, technology, business, trending, and community filters.
-
Base deployment
Trueo runs on Base, with trading, TYD, TRUE, and oracle contracts on that network. Users need a Base compatible wallet, Base USDC, and ETH for gas.
Trueo Fees
-
Trading fee The default v4 hook fee is 0, while the source comment lists 36 as 0.36%; administrators can change the rate.
-
Launchpad fees Market graduation and withdrawals during funding both incur a protocol fee, with live rates set in the contract.
-
Resolution bond Proposing a resolution requires a 250 TYD bond, and disputing it requires another 250 TYD bond.
-
Escalation bond Escalating a dispute requires a 750 TYD bond, while older markets may require 2500 TYD.
-
Account fees Trueo has no advertised monthly account fee or KYC fee.

How to use Trueo
-
Set up a Base wallet
Create a self-custodial EVM wallet such as MetaMask or Rabby, then add the Base network. Confirm that Trueo is available in your jurisdiction before depositing funds.
-
Fund your wallet
Buy or bridge USDC to Base and keep a small amount of Base ETH in the wallet for gas fees.
-
Open Trueo
Go to trueo.com and select Connect. Approve the connection in your wallet, then confirm that the site and network are correct.
-
Mint TYD
Use the vault flow to deposit USDC and receive TYD. TYD provides the collateral you use for trading, and its value can earn yield while your position remains open.
-
Review a market
Browse the market list or open a proposal page, then read the onchain question, approved sources, extra rules, end time, volume, and live fees before trading.
-
Choose an outcome
Buy YES if you think the event will happen, or buy NO if you think it will not. Select the amount, review the price and slippage, then approve the swap in your wallet.
-
Provide liquidity
If you want liquidity exposure, deposit TYD to mint equal amounts of YES and NO tokens, then add the tokens to their market pools. Review the pool terms and fees before confirming.
-
Fund a proposal
If you want to help launch a new market, deposit TYD behind a side during the funding phase. Check the funding threshold, withdrawal fee, and graduation fee before confirming.
-
Monitor resolution
After the event, watch the proposed outcome and its 12-hour challenge window. Dispute the proposal only when it breaks the market's written rules, and review the required bond before posting a dispute.
-
Redeem your winnings
After finalization, redeem the winning YES or NO tokens for 1 TYD each. If the market remains unresolved, burn one YES and one NO together to recover 1 TYD.
-
Verify transactions
Check Basescan when you need to confirm the market text, swaps, bonds, or resolution transaction. Use the contract addresses from Trueo's official documentation or GitHub.

Trueo Review
Pros
- Market questions, data sources, and resolution rules stay fixed onchain after launch.
- TYD collateral keeps earning yield through a Yearn vault while markets remain open.
- You can trade YES and NO tokens without giving custody of your funds to Trueo.
- Anyone can create a market proposal and fund it through the launchpad.
- Users can mint matching YES and NO tokens and provide liquidity themselves.
- Base transactions usually cost less than transactions on Ethereum mainnet.
Cons
- Liquidity is small, so large trades can face high slippage.
- Trueo runs on Base and has no official multi-chain support.
- Some markets have low volume and limited trading activity.
- The app does not always show trading and launchpad fees clearly.
- TYD adds exposure to USDC, Yearn, and smart contract risks.
- Resolution disputes require large bonds that may exclude casual users.
- The protocol is not a licensed betting product, so access depends on local law.
- Upgradeable contracts require trust in current admin roles and fee settings.
Our verdict
Trueo is a credible onchain prediction market on Base that supports binary YES or NO trades with TYD collateral, so open funds can earn Yearn yield while a market stays live. Its strongest features include immutable market rules, noncustodial swaps, and a layered resolution process with disputes, council review, TRUE votes, and reputation-based attesters. The tradeoff is thin liquidity, unclear live fees, Base-only access, and added USDC, Yearn, and smart contract risk, so large bets may face slippage and users must check contract settings themselves. I recommend Trueo for DeFi users with a Base wallet who want permissionless markets and yield on idle collateral, while people who need deep books, fiat access, or regulated betting should choose another venue.
Is Trueo safe & legit?
Trueo is a real onchain protocol made by the team formerly known as Truemarkets, with public contracts, Base deployments, and audits listed from Guardian Audits and iosiro. It has some recognition in the Polymarket community, including a past Discord-linked token allocation, but public trust remains limited. Known risks include thin liquidity, Yearn and USDC exposure through TYD, upgradeable contracts, unclear team identities, and a large team allocation; no major confirmed scam red flags are known.
