BetDEX

BetDEX is a peer-to-peer sports betting exchange built on Solana — the first licensed and regulated blockchain betting exchange in the world. It lets bettors set and match odds directly with each other, cutting out the house and charging just 3% commission on winning wagers instead of the 2–5% typical at centralised sportsbooks.

What BetDEX Is

Traditional sports betting platforms operate as bookmakers: they set odds, limit sharp bettors, ban winning accounts, and keep a wide margin. Betting exchanges like Betfair improved on that model by matching users against each other, but they still sit on centralised infrastructure with custodial fund management and limited transparency.

BetDEX applies the exchange model to a blockchain-native context. The platform is built on Solana and uses the Monaco Protocol, an open-source decentralised sports betting clearinghouse developed by the BetDEX team. When a bettor deposits funds, those funds sit in their own Solana-based wallet — BetDEX never takes custody. When a bet settles, winnings are paid directly to the player's wallet via smart contract. The books are public and transparent on-chain.

How It Works

BetDEX uses a hybrid architecture. Wallet management, deposits, withdrawals, and final settlement all run on-chain through Solana smart contracts. The order book and matching engine run off-chain via a REST API, giving the platform the speed needed to handle live betting markets without bottlenecking on block times.

Order matching follows FIFO logic with best-price execution: back orders match at the highest available odds, lay orders at the lowest, with earlier placements taking priority when odds are equal. The result is a familiar exchange interface — users can back outcomes (bet they happen) or lay them (bet they don't) — underpinned by the throughput and low fees of Solana, which processes transactions at roughly 0.00025 USD each and targets sub-400ms finality.

Team and Backing

BetDEX was founded in 2021 by three former FanDuel executives. Nigel Eccles, who co-founded FanDuel and served as its CEO, chairs BetDEX. Varun Sudhakar (CEO) and Stuart Tonner (CTO) round out the founding team. Their combined background spans more than two decades building consumer-facing sports betting products.

In November 2021 the company closed a 21 million USD seed round — at the time described as the largest seed raise by a UK startup. The round was led by Paradigm and FTX Ventures, with participation from Lightspeed Venture Partners, Sino Global Capital, and Solana Ventures. FTX subsequently collapsed in November 2022, but BetDEX has continued operating independently of that investor relationship.

The company is headquartered in Edinburgh, Scotland, with a remote-first structure and a US presence in New York.

Launch and Licensing

BetDEX went live on Solana mainnet on November 24, 2022 — coinciding with the 2022 FIFA World Cup, for which it offered zero-fee markets. In the weeks prior, it became the first sports betting exchange on blockchain to receive a regulatory licence, approved by the Isle of Man Gambling Supervision Commission (GSC). That licensing milestone was a deliberate strategic choice: operating as a regulated entity allows BetDEX to serve real-money customers in a range of markets without the legal ambiguity that surrounds most DeFi protocols.

Licences from Anjouan and Ireland have since expanded its reach to over 100 countries across Europe, Asia, Latin America, and Africa. In April 2026, BetDEX moved new registrations onto its Anjouan licence, with existing Irish-licence customers being migrated on advance notice as the platform consolidates its licensing structure. The company is pursuing additional licences, including in the United Kingdom and the United States.

The Monaco Protocol

Alongside its consumer exchange, BetDEX open-sourced the Monaco Protocol — a shared liquidity and clearinghouse layer for sports betting on Solana. The protocol is designed so that any developer can build a betting application on top of it, all drawing from the same liquidity pool. BetDEX Exchange is the flagship application, but the protocol itself is permissionless and open to the broader developer community.

To promote the ecosystem, BetDEX sponsored a track at a Solana hackathon focused on sports betting UX, naming DisBet as the winning project. The protocol positions BetDEX not just as a consumer product but as infrastructure for a broader category of blockchain-native wagering applications.

Markets and Fee Structure

BetDEX covers a growing range of sports including football (soccer), tennis, cricket, basketball, MMA, and esports. Supported currencies at launch included USDT, SOL, and SAMO.

The platform charges 3% commission on net winnings — a meaningful discount versus the 5–10% margins embedded in traditional sportsbook odds, and below Betfair's standard 5% charge. BetDEX's stated protocol-level fee target is under 1% on net winnings, with the consumer exchange sitting slightly above that as part of its licensed operating model.

The exchange does not ban or limit winning accounts. Because users are betting against each other rather than against the house, there is no structural incentive to exclude sharp bettors — a core selling point for experienced exchange users.

Current Status

BetDEX remains active as of September 2026, posting regular sports market commentary across social media. The platform has navigated the FTX fallout, continued expanding its licensing footprint, and maintained its regulatory-first positioning as a differentiator from DeFi prediction markets that operate without licences.

Its long-term ambition — becoming a global clearinghouse for sports wagering through the Monaco Protocol — remains a work in progress. Securing UK and US licences would be transformative for volume, but both jurisdictions present significant regulatory hurdles for blockchain-based products.
