Is a smart-contract crash game automatically more trustworthy than a Provably Fair one?

Not automatically. A smart contract removes the need to trust a company's private server, but you're now trusting that the contract code itself is correct and was actually audited — an unaudited or poorly-audited contract can still hide a bias. Check for a named audit firm and a real report, not just a badge.

Why don't more crash games run fully on-chain?

Cost and speed. Running every round's logic on Ethereum mainnet would add $1-8 of gas to every bet, which makes small-stakes play impractical. Games that go on-chain tend to pick low-fee chains like Solana or Arbitrum specifically to avoid that problem.

Can I verify a Provably Fair round after it happened?

Yes, if the casino implements it correctly — you should be able to take the revealed server seed, your client seed, and the round's nonce, and recompute the same SHA-256 hash the casino published before the round started. Our Provably Fair verifier tool walks through this step by step.

Every crash game you'll find online falls into one of two settlement models, and the difference matters more than most casino marketing explains.

Centralized Provably Fair games

Most crash games — Aviator, JetX, Spaceman, and the majority of the genre — run on the casino's own servers. Fairness is guaranteed through a Provably Fair system: before a round starts, the server commits to a hashed "server seed" you can't see, combines it with a client seed you can influence, and after the round reveals the original seed so you can independently recompute the SHA-256 hash and confirm the result wasn't altered after the fact.

This model is fast, cheap to run (no gas fees on the game logic itself), and — when implemented correctly and verified — genuinely tamper-resistant. The catch is trust in implementation: you're verifying that a specific round's hash matches, but you're trusting the casino's server code overall wasn't built to cheat before that point.

On-chain smart-contract games

A smaller but growing set of crash games run the entire round logic as a smart contract on a blockchain like Ethereum, Solana, or Arbitrum. The randomness source, the crash-point calculation, and the payout are all executed and recorded on-chain, meaning anyone can audit the contract code directly on a block explorer rather than trusting a company's server.

The tradeoff is cost and speed: on-chain games inherit whatever gas fee and confirmation time their host chain has, which is why on-chain crash games have concentrated on low-fee chains like Solana and Arbitrum rather than Ethereum mainnet.

Which should you choose?

Neither model is strictly "safer" — a well-implemented Provably Fair centralized game and a well-audited smart contract can both be legitimately fair, and a badly-run version of either can't. What matters practically: check whether a Provably Fair implementation actually lets you verify a real round (not just claims to), and for on-chain games, check whether the contract has a published audit from a named firm rather than just an unverified claim of one.
