Prediction Markets

Which wallets are supported when using DFlow?

Any Solana wallet that supports standard transaction signing is compatible.

What slippage and fees should I expect when building a swap/trade UI?

Slippage depends on market liquidity and trade size, while fees include network fees plus any DEX, priority, or platform fees applied at execution.

Can users trade without KYC when using my app built on DFlow?

Yes, trades are non-custodial and do not require KYC, unless your application adds its own requirements.

How do sync vs async trades work, and why are prediction market trades always async?

Sync trades settle atomically in one transaction, while async trades span multiple transactions; prediction markets are async because market interactions cannot be completed atomically.

Does DFlow custody user funds at any point?

No, user funds remain in the user’s wallet throughout the entire trade lifecycle.

Why does a market order trigger a “create account” cost onchain?

Because when a market is uninitialized, the /order endpoint performs on-demand market tokenization (creating the YES/NO outcome tokens) before executing the swap, which incurs a small onchain account creation fee. See the full explanation here.

Do you support any form of gas sponsorship?

You can implement gasless swaps with our sponsor parameter.

How do I get access to the Prediction Markets API?

You can access the API via our developer endpoints now, for production use, you’ll need an API key to avoid rate limits.

Are platform fees supported for prediction markets?

Yes. You have to use platformFeeScale.

Are all markets guaranteed to settle in USDC?

We support two settlement mints at the moment, USDC and CASH. The market will settle in whichever settlement mint the outcome token mint belongs to. See this recipe for more details.

How do I fetch market images from Kalshi?

We don’t currently have images on markets (just events). Adding images for markets is being worked on currently, but for now you can fetch these from Kalshi directly.

How much does it cost to initialize a not-yet-tokenized market?

Initialization is about 0.02 SOL and is paid in SOL (not USDC). This fee applies only when a market is not yet tokenized.

What is the minimum USDC amount per order?

The minimum is 0.01 USDC, but some markets require more because the smallest purchasable unit is one contract and the minimum depends on the contract price.

Can users buy a fractional contract?

No.

What exactly are the "tokens" I get when trading Kalshi markets via DFlow?

They are outcome tokens that represent positions in a prediction market.

How do I handle prediction market resolution and settlement in my app?

After resolution, users redeem outcome tokens for value according to the market result. This creates a second phase of UX that does not exist in spot trading: redemption flows, position closeout UX, and history and receipts UX.

How are fees structured for the Prediction Markets API?

Prediction market fees are calculated based on trading volume and are subject to a fee tier system.

Can I build advanced features like position tracking, portfolio views, or automated trading with DFlow?

Yes, you can build advanced features like position tracking, portfolio views, or automated trading with DFlow. The only limit to what you can build is your imagination.

How does the tokenization of markets work and where does the liquidity come from?

Prediction market tokens are tokens that represent positions in a prediction market. They are minted when a user enters a position and burned when a user redeems a position. The liquidity for prediction market tokens comes from the Concurrent Liquidity Programs (CLPs).

What is the market lifecycle/status flow, and how do I poll for updates (e.g., active → determined → redeemable)?

Prediction market lifecycle is a fixed sequence from creation to final settlement. A market’s status defines what actions users and builders can take at each stage.
