Introduction

Cyphers is a prediction market on Solana. The twist: your bet - which side you picked - stays private until the market settles. Other prediction markets publish every bet to anyone who can read a block explorer. Cyphers doesn't.

Why hidden bets matter

In a normal prediction market, every bet is a public record:

A market on "Will Bitcoin hit $200k this year?" shows everyone who bet YES, who bet NO, and how much.
Whales watching the order flow can see whichever way a market is leaning and trade against it.
Bots can copy whatever the smart money is doing within seconds.
Your political bets, sports bets, or anything else become part of your public on-chain profile.

This isn't a hypothetical problem. On every major prediction market today, public bets are routinely scraped, indexed, and used to front-run new positions.

Cyphers fixes this by encrypting the side of every bet before it lands on chain. The amount is still public - the protocol needs it to track funds - but which side you picked is hidden until the market closes.

What stays private, what doesn't

It helps to be precise about what Cyphers does and doesn't hide.

What	Hidden?
Your chosen side (YES vs NO, or which option)	Yes, until the market settles
Your stake amount	No - visible on chain
Your wallet address	No
That you bet on a specific market	No
The result of the market once it resolves	No - public, like any settlement

So Cyphers hides your prediction, not your participation. If you're betting $50 on a YesNo market, the network sees a wallet bet $50, but not whether it was on YES or NO.

How a market works, in three steps

Pick any market in the app and the flow is the same:

You bet. You pick a side, choose an amount, and confirm. Cyphers encrypts your side in your browser before sending it to Solana.
The market closes. When the close time passes, betting stops. The market enters a waiting state until a resolver posts the real-world outcome.
Settlement. The Arcium network decrypts every bet at once, computes who won and how much, and writes the result back to Solana. After a short challenge window (so anyone can flag a bad resolution), winners can claim their USDC.

Two market types

Cyphers supports two shapes of markets. That's it - no hidden tiers or modes.

YesNo. A binary question with two possible answers. "Will BTC close above $100k on 1 Jan 2026?"
MultiOutcome. A question with 2-4 named options. "Which chain has the most TVL on 1 Jan 2026? [Solana | Ethereum | Base]"

For when to use which, see Market types.

A few things to be aware of

USDC, not SOL. Every bet and payout uses USDC. You'll need USDC in your wallet to bet.
Minimum bet is $1. Markets accept any amount from $1 upward, in USDC.
A small fee comes out. Two small fees are deducted from every bet: a protocol fee (up to 1%) and a market-creator fee (up to 5%). The breakdown is on Fees.
There's a wait at settlement. When a market closes, the off-chain decryption takes around 10 seconds. The challenge window after that is 24 to 48 hours.

No - visible on chain

Your wallet address

No - public, like any settlement
