Decentralized Prediction Markets
DPM is Plaee’s prediction market infrastructure. Plaee runs the trading interface, the order book and on‑chain settlement. You choose how it connects to your platform and who holds the funds.

Prediction markets have gone mainstream.
Trading on real‑world outcomes such as elections, sports, crypto and the economy has moved from a niche to a category people look for. Users now expect to find it next to the products they already use.
Building an exchange in‑house is slow and hard to get right. You need matching, liquidity, custody and settlement. DPM gives operators all four as infrastructure, so you can offer prediction markets without building them.
Infrastructure, not just a widget.
Shared liquidity
Every DPM operator trades on one exchange. Your users’ orders match against users from every other operator, not just your own.
Speed first
Orders match instantly in Plaee’s off‑chain order book. Only settlement goes on‑chain, so trading feels like any other app.
Fits any operator
You can start a new platform, add it next to an existing one, or run it on your main balance. Three deployment models cover all three.
Robust by design
Keys stay in a hardware enclave, each user has an on‑chain proxy, and settlement is fully collateralized in USDC. The custody setup matches the model you choose.

Shared Balance
Users trade from the balance they already have with you. You sign every order and stay the only custodian.
For one balance, full operator control
From click to settlement.
This is the path an order takes in an integrated deployment. The funding step depends on the model.
1
User clicks Buy in your app
The DPM trading interface runs inside your app as an iFrame.
2
Funds are checked
Shared Balance: your backend checks and debits the user’s balance. Segregated: USDC comes from the user’s own trading wallet.
3
The order is signed
Keys stay in Turnkey’s TEE. They sign orders but never leave the enclave.
4
Plaee matches it
The signed order goes into Plaee’s off‑chain order book, where matching is instant.
5
Polygon settles it
The trade contract takes the USDC and delivers outcome tokens to the user’s proxy contract.
6
Winners redeem
When the user redeems winning tokens, the contract pays out in USDC.
Common questions
Who builds DPM?
Plaee. Plaee builds and runs the platform engine, the trading interface and the order book.
Do our users need crypto wallets?
No. In the Segregated and Shared Balance models, each user gets an on‑chain proxy address automatically on first visit. They never see a seed phrase or need to hold gas tokens.
Who pays gas?
Plaee sponsors gas. Your wallets hold USDC only, so you track a single asset.
Can Plaee move our funds?
In Shared Balance, no: every order needs your signature, and you are the only one with access to the keys. In Segregated, Plaee shares access to the Operation wallet only. That wallet can send funds to user wallets or back to your Master wallet, never to an outside address. Plaee has no access to the Master wallet.
Which model should we choose?
If you have no platform yet, choose Standalone. If you want prediction funds walled off from the main balance, choose Segregated. If users should trade straight from their existing balance, choose Shared Balance.
