PvP crypto casino games: custody, fairness and fees

Most P2P crypto casino sites, including every crypto site we list, are custodial. You send coins to a deposit address, the site credits an on-site balance, and both stakes sit in the operator's wallet until it pays the winner. A withdrawal happens on the operator's terms: Acebet caps daily winnings at €100,000 and reserves ID checks at any withdrawal level, and Online Money Games holds every balance and its key and caps withdrawals at 50 SOL a day.

Non-custodial games settle from your own wallet. Solpump has you sign each bet from a Solana wallet, and on Suigar a smart contract holds both coinflip stakes until it pays the winner. Polymarket describes its international site as non-custodial, and SX Bet runs an on-chain order book in USDC.

On-chain play swaps operator risk for smart-contract risk. A bug can lose the pot, and a transaction from your wallet cannot be reversed. Suigar's terms list "bugs, contract vulnerabilities" as a risk, and its published audit covers a coinflip module but no PvP coinflip module. Solpump says auditors reviewed its contracts; we found no report. Liquidity can be thin too: in Suigar's lobby on 27 October 2026, one account, suigar.sui, was in all 12 recent duels.

None of these on-chain venues is in our list. Suigar and SX Bet state no gambling licence, Solpump's Tuvalu number sits on a register run by the authority's appointed licensing agent, and Polymarket's international site blocks the US and UK. Azuro-based books such as bookmaker.xyz pool liquidity, so you bet against a pool, not a matched player.

Crash looks social: everyone watches one rising multiplier and the chat shows other players cashing out. But every cash-out is paid by the operator at the game's built-in edge, and nobody wins money from anyone else. Dice, limbo, mines and plinko "originals" are single-player bets against the house in the same way. Acebet's licensing page separates its SHA-256 provably fair Originals from the third-party slots its battles run on.

A PvP crash, with the pot split among players, exists on paper: Rollspace's documentation described one paying 98% to winners, but the page returned an error when checked in October 2026. A crash game is house-banked unless its rules say the winnings come from other players' stakes.

Every crypto site we list holds an offshore licence from Anjouan, Curaçao or Tobique, and every one excludes the UK and the US in its terms or licence. The licence lets the company run from that jurisdiction; it does not make the site legal where you are.

In Great Britain, a licensee must notify the Gambling Commission before it takes crypto, and serving British players without a Gambling Commission licence is a criminal offence. Offshore sites are not part of GAMSTOP. Australia bans online casino games, P2P ones included, and its licensed wagering sites have been barred from taking crypto since 11 June 2024. India has banned real-money online games, skill games included, since 1 May 2026.
