BetDEX

BetDEX is a sports betting exchange where you bet against other people instead of a bookmaker. You back an outcome to win or lay it to lose, at odds set by other users. It takes 1% of your net winnings on each market. It says it does not limit or ban winning accounts.

You pay in with crypto such as SOL or USDC. Your money sits in a Solana wallet that BetDEX runs for you. Former FanDuel executives set up the firm in 2021, and the exchange went live on Solana in November 2022. Since July 2026 it has run under a gaming licence from Anjouan, an island in the Comoros.

How BetDEX exchange betting works: back, lay and order matching

On BetDEX you either back a pick (bet that it wins) or lay it (bet that it loses, so you act as the bookie). Each bet needs a user on the other side. Your order waits in the order book until someone takes it.

BetDEX's docs say orders match first in, first out at the best price. A back order fills at the highest odds on offer, and a lay order at the lowest. Any part of your stake that is not matched stays open until someone takes it, you cancel it or the market shuts.

Cross-matching, which would treat a back on one outcome as a lay on the others to deepen the book, is still in development on the roadmap. Cash out and Asian handicap lines are listed there too.

Solana only handles the money side. Deposits and withdrawals go on-chain, so you can trace your funds. Placing, matching and settling bets all happen in BetDEX's own systems. Its terms of service say these run on its internal records, "not by public blockchain transactions or smart contracts."

BetDEX commission: 1% of net winnings, no premium charge

BetDEX takes 1% of your net profit on each market. If you lose or break even on a market, you pay nothing. The commission page says all users pay the same rate, and winners pay no extra fee.

The rate used to be higher. When the exchange relaunched in May 2024, it took 3% of net winnings.

Promotions have cut the fee further for short periods. For the 2026 World Cup, BetDEX refunded all commission on its World Cup markets, up to 500 USD per user.

A two-week high-volume promotion, now ended, dropped the rate to 0.8% or 0.5% for users who traded large sums each week.

BetDEX deposits and withdrawals: BTC, SOL, USDC and USDT

You fund a BetDEX account with crypto. The deposit guide lists Bitcoin, SOL, USDC and USDT, with Ethereum marked as coming soon. Each deposit turns into USDC at once, with no fee, so your balance and your bets are in dollars. The docs also show how to send funds from Binance, Coinbase, OKX, Skrill or PayPal.

Withdrawals are crypto only for now, in USDC, USDT, BTC or SOL. Taking out USDC on Solana is free. Other coins or networks carry conversion and network fees. Withdrawals to a bank account or card, and cash deposits in pounds, euros and dollars, are listed as planned.

BetDEX sports markets, trading API and brokerage for big bets

The exchange covers football, basketball, American football, tennis, ice hockey, cricket, MMA, baseball, boxing and rugby. Its rules pages add darts, esports, chess, golf, racing and snooker. Football markets go past the match result to handicaps and goal totals. It also ran markets on the 2024 US election.

Traders can link their own tools through a REST and websocket API. Users create their API credentials from the account dashboard. The limit is 500 requests per second.

Some bets are too big for the order book. For those, BetDEX Brokerage gets prices from outside counterparties that quote large bets. It pitches the service at stakes of 5,000 USD up to 50,000 USD and more. A broker sends you the prices on offer. If you accept, the bet shows in your account like any other.

Is BetDEX legit? Licence, KYC and where it is available

BetDEX holds a gaming licence, but it now comes from a small offshore body. Its website says the holder is its subsidiary, Stucktaymore Limited. The licence was granted by the government of Anjouan in the Comoros, under number ALSI-092404022-FI2. Its terms say all accounts moved to it on 1 July 2026. The Irish licence no longer applies.

It held licences from better-known bodies before. In November 2022 it became the first blockchain betting exchange to get a licence from the Isle of Man. In July 2023 it won a betting licence in Ireland.

The test lab GLI checked the exchange against its Isle of Man licence rules. BetDEX's GLI page calls it a rules check of the platform. It does not say GLI looked at the Solana program code. The check also came before the move to Anjouan.

To sign up, you confirm you are over 18. Past certain limits, BetDEX asks you to prove who you are. That can mean a passport or driving licence and proof of address. At times it also asks for bank statements or proof of wealth. The terms bar users from a list of countries that includes Russia, Iran, North Korea and Syria. The site also checks where you are and blocks sign-ups from places it does not serve.

Is BetDEX safe? Custody, licensing and protocol risks

BetDEX holds your money. Each account gets a Solana wallet, but BetDEX manages its private keys. Bets settle in BetDEX's own records. So you rely on the company and its licence, as you would with any online bookmaker. The blockchain only shows your deposits and withdrawals.

The licence is the second risk. In October 2026 the Comoros government asked the UK for help to deal with the Anjouan licence scheme, Gambling.com reports. The country's central bank said the scheme used the Comoros name to look legitimate. Gambling.com says an Anjouan licence costs about £19,000, far less than a Curaçao one.

BetDEX's terms also let it suspend or close accounts at any time, with or without notice. Complaints go to its support team first, then to its own dispute process.

The The Monaco Protocol program is a smaller risk. BetDEX built it as an open-source betting engine on Solana. Solscan shows one address can still upgrade the program, and the code is not marked as a verified build. The program showed no use in the 30 days to early November 2026, which fits with betting now running off-chain.

Who BetDEX is for, and who should skip it

BetDEX suits experienced bettors who have been limited by bookmakers and already hold crypto. It fits best if you trade prices on football, the NBA, the NFL or tennis. A flat 1% fee with no extra charge on winners matters most to people who bet often. The API and the brokerage desk serve automated traders and large stakes.

It is a poor fit if you want to hold your own funds, or if you want a regulator like the Isle of Man or Ireland behind your account. You also need crypto to pay in and to cash out. For anyone who bets, BetDEX offers deposit limits, time-outs and self-exclusion, and points to support groups such as GamCare.

BetDEX vs Betfair, Smarkets and other betting exchanges

By its own figures, BetDEX charges less than the big exchanges. Its fee page sets out the gap:

The catch is the firm behind the price. BetDEX takes crypto and runs on an Anjouan licence. Betfair and Smarkets are licensed in the UK. Crypto sites such as Polymarket are a different thing. They sell shares in events like elections, while BetDEX runs a book of sports bets.

BetDEX team, funding and history

Nigel Eccles, Varun Sudhakar and Stuart Tonner founded BetDEX Labs in October 2021. Eccles co-founded FanDuel and ran it as chief executive. At BetDEX he is chair, Sudhakar is chief executive and Tonner runs the tech. The firm says its team helped launch Betfair, BETDAQ and FanDuel. Eccles and Sudhakar talked through the model on the Lightspeed podcast.

In November 2021 the Edinburgh firm raised a 21 million USD seed round. Paradigm and FTX led it, and Lightspeed, Sino Global Capital, Solana Ventures and Multicoin Capital also took part. BetDEX called it the largest seed round by a UK startup at the time.

The team also built the Monaco Protocol, a shared betting engine on Solana that any app could plug into. BetDEX Exchange was its first app when it went live on Solana in November 2022. The exchange now runs its order book off-chain. BetDEX's docs describe no token.
