Is Myriad Markets legit?
Yes, it is a working market with a known owner. It is not regulated. Dastan, the company behind the crypto news site Decrypt and Rug Radio, owns and runs it.
The contract you sign is with Myriad Foundation, a company organized under the laws of Grand Cayman. Its terms send disputes to binding arbitration and waive jury trials and class actions. They also cap Myriad's liability at $50, or the fees you paid in the last 12 months if lower.
Myriad went live on the Abstract network in January 2025, first with points that had no cash value. Real-money USDC markets followed in March 2025. In 2026 it moved its main catalog to BNB Chain and to USD1, the stablecoin from World Liberty Financial.
In March 2026 it closed a seed round. MoonPay Ventures, Walrus and Fundstrat co-founder Tom Lee were among the investors. Decrypt, a sister company, reported the round and discloses the link.
It is small. DefiLlama counts $235 million traded since July 2025, most of it in early 2026. Only about $412,000 traded in the 30 days to October 28, 2026. Users held about $222,000 in its contracts that day.
Here is what unregulated means for you. No regulator checks how Myriad runs or settles its markets. No compensation scheme backs your balance. A dispute goes to arbitration, and Myriad's liability is capped at $50.
Is Myriad Markets safe? How your money is held
Myriad does not hold your money the way an exchange does. Your Myriad Account is a self-custody crypto wallet, built with the wallet provider thirdweb. Your funds sit in that wallet or in Myriad's smart contracts. You can export the wallet's private key from your settings and use it in MetaMask or Trust Wallet.
The bigger risk is who decides the result. The Myriad team resolves markets under each market's written rules. Crypto price markets and the 2026 World Cup markets settle on Chainlink data instead. Whoever controls a resolving wallet decides which shares pay $1.
That is exactly what failed in October 2026. An attacker got the key to an internal wallet that resolved some markets automatically. User wallets were not drained. The attacker forced wrong results, then tried to collect the payouts.
The security firm Cyfrin audited Myriad's AMM contracts in July 2025. It audited the order-book contracts in March and April 2026. An audit checks the code, not how the team guards its keys.
Protect yourself the usual way. Keep only what you are trading on Myriad, and withdraw the rest. Never share your private key; Myriad says it will never ask for it. Read each market's rules, because they decide how it settles.
Is Myriad Markets gambling?
Myriad calls itself a prediction market. You buy shares in an outcome, and a wrong call loses your stake. That works like a wager, whatever the label.
In the US, prediction markets are legal as derivatives on exchanges the CFTC regulates, such as Kalshi. Myriad has no such registration, and its terms bar Americans.
Some Myriad markets use points with no cash value. Those work more like Manifold, where nothing real is at stake. Elsewhere, whether real-money markets count as gambling depends on local law.
The October 2026 Myriad hack, and other complaints
We found no confirmed security incident at Myriad before October 2026. Then one of its own wallets was turned against its markets.
- An attacker forces the results of 10 markets At 06:07 UTC, an attacker used a compromised internal wallet that Myriad used to create and resolve some markets. The attacker bought unlikely outcomes, declared them the winners and claimed the payouts. Myriad says it revoked the wallet's admin rights within minutes of being alerted. Source
- Myriad publishes its incident report Myriad said the wallet's key leaked weeks earlier through a flaw in a third-party library in one backend service. It said it unwound the attacker's last large buy and that “the attacker withdrew nothing.” It voided all 10 markets, all on its BNB Chain AMM. Source
- Myriad promises automatic refunds Holders on both sides get their shares times each outcome's last price before the attack. Winnings already claimed from a forced result are deducted. Refunds come from recovered funds and the market pools, with no claim needed. Source
- On-chain records can't confirm the recovery yet The Defiant traced about 11,609 USDT claimed from the OpenAI-versus-Anthropic IPO market, later moved to another address. Myriad says it moved funds to wallets it controls. Transfers alone do not show who controls an address. Source
Note what “voided” means here. You get the last price before the attack, not your entry price. Bought Yes at 30¢, and it traded at 20¢ before the attack? You get 20¢ a share back.
As of October 28, 2026, Myriad had not confirmed any refund paid. Its public market data still listed the forced results as resolved, not voided. Myriad had warned that portfolios might show the wrong outcome until it fixes them.
The same week, Predict.fun, also on BNB Chain, failed differently. There, about 400,000 USDT left users' own wallets. At Myriad, the attacker hit market settlement, not user wallets. Both cases show the same thing: the operator's own keys are part of your risk.
How Myriad Markets works
Every market is a question, and each answer trades as shares priced between $0 and $1. A winning share pays $1 when the market settles, and a losing one pays nothing. Myriad runs two models: AMM pools on many markets and an order book on others. Your fee depends on which one you trade.
| Cost of the contracts | $40.00 |
| Fee | Shown before you trade |
| Paid out if the answer is Yes | $100.00, less the fee |
| Paid out if the answer is No | $0.00, a loss of $40.00 plus the fee |
On an order-book market with the most common 1% peak, the fee in this example is $0.32. That is 0.8% of $40, because the rate shrinks as the price moves away from 50¢. On an AMM market with a 2% buy fee, it would be $0.80.
On the order book, a Myriad service matches orders off-chain, and smart contracts settle them on BNB Chain. On AMM markets, a pool sets the price, and the prices of all outcomes add up to $1. Either way, you can sell any time before the market closes.
Myriad Markets fees, with the arithmetic
Order-book takers pay a rate that peaks at 50¢, 1% on most markets, and AMM markets charge 0% to 2% on buys.
The order-book rate is peak × the lower of price and 1 − price, divided by 0.5. Myriad's docs say the peak is 1.5%. Its own market data on October 28, 2026, showed 1% on 170 of 245 open order-book markets. The rest showed 0.75% or 1.8%.
Makers, whose limit orders wait on the book, pay nothing. At launch they get 100% of takers' fees back as rebates, paid periodically. Resting limit orders also earn the most MYR Points.
AMM markets charge 0% to 2% on buys, set per market and shown before you trade. Featured Spotlight markets charge 0% or 0.2%, and perpetual sentiment markets charge nothing. The web app adds $0.0085 per transaction to cover gas.
Myriad's docs publish no deposit or withdrawal fee. MoonPay handles card and other cash deposits, and Myriad does not list MoonPay's charges. Refer a trader, and you can earn up to 33% of the fees they pay.
Does Myriad Markets pay out? Settlement and withdrawals
Each winning share pays $1 once its market resolves. You claim it yourself from the top of your Portfolio. Myriad says most markets resolve within minutes of expiring, and some take up to 48 hours.
If a market is voided, you get the market value of your shares at the time of cancellation. That can be a profit or a loss. The October 2026 refunds use the last price before the attack instead.
You can withdraw any amount as USD1 to a BNB Chain wallet, or as USDC.e to a connected Abstract wallet. Myriad publishes no withdrawal time or limit. A wrong address cannot be reversed, so check it twice. We found no reports of withdrawals held back.
| Deposited by | Minimum | Withdrawn as |
|---|---|---|
| USD1 sent on BNB Chain | $3 | USD1 to any BNB Chain wallet |
| Other crypto, through MoonPay | $3 | USD1 to any BNB Chain wallet |
| Card, Apple Pay, Venmo or Revolut, through MoonPay | $20 | USD1 to any BNB Chain wallet |
| ETH or USDC.e from an Abstract wallet | Not stated | USDC.e to your Abstract wallet |
What you can trade on Myriad Markets
On October 28, 2026, Myriad had 245 open order-book markets, all in USD1 on BNB Chain. Most were on the economy, culture and sports. The rest covered crypto and politics. A smaller set of AMM markets, mostly on crypto, ran on BNB Chain, Abstract, Linea and Celo.
A few formats stand out. HIT markets have no end date and resolve when an outcome happens. Perpetual sentiment markets, such as Fear vs Greed, never resolve and charge no fee. Candles are short, automated crypto markets settled in USD1.
Some markets on Abstract and Celo use points, not money. Points markets cost nothing to join and pay nothing in cash.
Trading is thin, so large orders can move the price or fail to fill. The app uses fill-or-kill market orders: an order fills in full or not at all.
Where Myriad Markets is available
Not in the US. Its terms bar anyone residing in or associated with 19 places. They are the United States, Ontario, France, Malta, Switzerland, Singapore and the Bahamas. Also barred: Botswana, the British Virgin Islands, Cambodia, the Cayman Islands, Trinidad and Tobago and Zimbabwe. So are North Korea, Iran, Libya, Somalia, Sudan and Syria.
The UK and Australia are not on the list, but local law still applies. Using a VPN to get around the list breaks the terms. We found no identity check in Myriad's docs or terms.
In the US, the regulated choices are Kalshi and Polymarket US. Check whether prediction markets are legal in your state first.
Not legal advice.
Is there a Myriad Markets app?
Not a standalone one: we found no Myriad app on the App Store. You trade at myriad.markets in a browser. Trust Wallet also offers Myriad markets in its app, under Predictions in the Swap menu. Developers can trade through Myriad's API and command-line tool.
Myriad Markets pros and cons
Pros
- You hold the keys. Your Myriad Account is a self-custody wallet, and you can export its private key.
- Low order-book fees. Takers pay at most 1% on most order-book markets, and makers pay nothing.
- A fast response and a refund plan. Myriad cut off the attacker within minutes and promised automatic refunds at pre-attack prices.
- Small minimums. Crypto deposits start at $3, and card deposits through MoonPay start at $20.
Cons
- The team decides most results. October 2026 showed what happens when a resolving key leaks.
- No regulator. Cayman law, binding arbitration and a $50 cap on Myriad's liability.
- Closed to the US. And to France, Ontario, Singapore, Switzerland and 14 other places.
- Thin trading. About $412,000 traded in the 30 days to October 28, 2026, per DefiLlama.
Myriad Markets vs the alternatives
Outside the US, Polymarket is the larger crypto choice, with far more trading. Opinion also runs on BNB Chain. Predict.fun is on BNB Chain too, but it had its own breach in October 2026.
In the US, use a regulated exchange such as Kalshi. For crypto-focused markets, see our ranking of crypto prediction markets.
Our verdict: should you use Myriad Markets?
If you are in the US or another barred country, no. Its terms bar you, and a VPN breaks them.
Elsewhere, it is a credible but small market with low order-book fees and self-custody wallets. The October hack hit settlement, not wallets, and Myriad acted within minutes. Until the refunds are paid, trade small, read each market's rules and withdraw what you are not using.
