Microset runs parimutuel prediction markets on Solana. You stake on an
outcome; when the event settles, everyone who picked the winning outcome shares
the pool. This page explains, in plain terms, what happens to your money at each
step.
The basics
A market is a question with two or more possible outcomes — for example, “How many runs on the next ball?” You make a prediction on the outcome you think will happen. All predictions for a market go into a single on-chain vault. When the result is known, the market is resolved to one winning outcome, and the pool is split among the people who picked it. Markets aren’t limited to Yes/No — a market can have anywhere from 2 outcomes up to several, so the same system works for any sport or event.A worked example
Take a 6-outcome cricket market, “Runs on Next Ball”:| Your pick | Outcome |
|---|---|
| Dot ball | 0 runs |
| 1 run | 1 |
| 2 runs | 2 |
| 3 runs | 3 |
| 4 / boundary | 4 |
| Six | 6 |
- A small protocol fee is taken from the total pool.
- Everyone who predicted 4 splits the rest of the pool, in proportion to how much they staked.
- The other five outcomes win nothing — their stakes flow to the winners.
How your money is handled
Non-custodial
Your funds move only when you sign a transaction. Microset never holds your
private keys.
One on-chain vault
Each market’s stakes are held in a program-controlled vault and paid out only
by fixed on-chain rules.
Proportional payouts
Winners share the pool in proportion to their stake on the winning outcome.
Refunds if voided
If a market is voided, everyone gets a full refund of their stake — no fee.
What you can do
Make a prediction
Choose a market and an outcome, enter an amount, and sign the transaction. Your
stake moves into the market’s vault. You can predict until the market’s close time.
Wait for resolution
After the event, the market is resolved to the winning outcome. A protocol fee
is taken from the pool and the rest is locked in for winners to claim.
Claim your winnings
If you picked the winning outcome, claim your share. Your payout is sent
straight to your wallet.
Quick predictions (optional)
To make several predictions without approving each one in your wallet, you can create a quick-prediction session: you sign once to fund a small on-chain escrow with a spend limit you choose. Predictions are then placed from that escrow up to the limit. You stay in control — the session has a cap, and you can withdraw unused funds or revoke it at any time.Built-in safety
The program enforces these rules on-chain, so they can’t be bypassed:| Protection | What it means for you |
|---|---|
| Only winners can claim | If you didn’t pick the winning outcome, the claim is rejected — no one can drain the pool. |
| No double claims | Once you’ve claimed a market, you can’t claim it again. |
| No predictions after resolution | A market can’t be resolved and still take new predictions — the result is locked. |
| Single resolution | A market is resolved exactly once; outcomes can’t be flipped afterward. |
| Capped fees | The protocol fee has a hard upper limit enforced in code. |
| Full refunds on void | A voided market returns every stake in full, with no fee. |
Fees
A configurable protocol fee is taken from the total pool at resolution and sent to the protocol treasury. The fee is a small percentage and is capped on-chain. Voided markets are refunded in full with no fee.Good to know
- Solana transactions are final once confirmed — predictions and claims can’t be reversed.
- Outcomes are not set by Microset — resolution is triggered by third-party sports data APIs (e.g. Roanuz) once the real-world result is known.
- Microset is sport-agnostic: the same market mechanics work for cricket, football, basketball, and more.
