[Solflash_bet]

Hi Bitcointalk,

Solflash is a fully on-chain, non-custodial casino running on Solana. There is no account, no deposit and no balance held by us: you connect your wallet, you sign each bet, and winnings are paid back to your wallet instantly. Every game is provably fair and settled on-chain, so you never have to trust us with your funds.
 
━━━ Why Solflash ━━━

• Non-custodial - your keys, your coins. We never hold your funds.
• No deposit, no sign-up - connect your wallet and play. Nothing to register.
• Provably fair - every outcome is committed on-chain and verifiable.
• Instant payouts - winnings are sent to your wallet in seconds.
• Low house edge - from 1% (Dice).
• 100% on-chain - every bet and payout settles on Solana, viewable on Solscan.
• Private by design - cookieless, no trackers.

━━━ 10 original games - house edge & RTP ━━━

• Blackjack - ~0.5% edge · RTP ~99.5% (basic strategy)
• Dice - 1% edge · RTP 99%
• Mines - 1% edge · RTP 99%
• Tower - 1% edge · RTP 99%
• Limbo - 1% edge · RTP 99%
• HiLo - 1% edge · RTP 99%
• Coin Flip - 1% edge · RTP 99%
• Plinko - ~1% edge · RTP up to 99% (varies by risk)
• Wheel - 1.4% edge · RTP 98.6%
• Roulette - 2.70% edge · RTP 97.3%

━━━ How it works ━━━
Connect your Solana wallet: Phantom, Solflare, Backpack, Trust Wallet, Coinbase Wallet, MetaMask, Glow, Exodus or Atomic Wallet.
Pick a game, set your bet, and sign the transaction - you only pay the small Solana network fee.
The outcome settles on-chain and any winnings hit your wallet immediately.
 
━━━ Provably fair ━━━
Solflash uses a commit-reveal scheme: the server seed is hashed and committed before you play, then revealed afterwards, so no result can be altered after the fact. Every bet and payout is an on-chain transaction you can inspect yourself on Solscan. All games run in a single on-chain program on Solana mainnet you can inspect yourself: 4rBCVPMsVrxUBCmh8MuK4nR7beBAz7j5rAW3xNiaxBfh.
 
━━━ Fees & house edge ━━━
House edge starts at 1% (Dice) - that's an RTP up to 99%. It varies by game. No deposit fees, no withdrawal fees - you only pay the tiny Solana network fee when you sign a bet.
 
━━━ Responsible gaming ━━━
18+ only. On-chain self-exclusion is available and cannot be lifted early. Access is geo-restricted and the games are offered only where online gambling is lawful in your jurisdiction. Please gamble responsibly and only play what you can afford to lose.
 
━━━ Operator ━━━
Solflash is operated by Tessera Labs S.R.L., a company incorporated in Costa Rica (corporate ID / cédula jurídica 3-102-969810).

Welcome to the forum. I see that your casino doesn't have a license, so I researched it:

Solflash is owned and operated by Tessera Labs S.R.L., incorporated in the Republic of Costa Rica under corporate ID (cédula jurídica) 3-102-969810. Solflash offers provably-fair, non-custodial games running on the Solana blockchain.

source: https://www.solflash.bet/en/play

And all I found was:

https://tessera-labs.com/   ( This definitely has nothing to do with your casino )

https://tesseralabs.ai/  ( It definitely has nothing to do with your casino either )

https://thetesseralabs.info/ ( definitely has nothing to do with your casino )

So let's imagine someone has a problem with your casino. This person searches your casino website for the address they can go to in order to legally sue your casino. They see on your website that it says the casino is operated by Tessera Labs S.R.L., located in the Republic of Costa Rica. This person then travels to Costa Rica to locate this address. My question is: will this person in Costa Rica be able to find the address of Tessera Labs S.R.L.? Or is this a company created solely online without any physical office, serving only to enhance the website's image?

Solflash is operated by Tessera Labs S.R.L., which is registered in Costa Rica under corporate ID (cédula jurídica) 3-102-969810.
To verify its existence, you can register a free account on the official Costa Rican National Registry website (Registro Nacional de Costa Rica): https://www.rnpdigital.com/.

Every legally incorporated company in Costa Rica is required by law to have a registered physical address (domicilio social) and a local legal representative to receive official and legal correspondence.

However, in the gambling industry, this registered address is often the offices of a local law firm or a corporate service provider acting on behalf of the company, rather than a physical casino office with a support desk. Therefore, traveling there in person to resolve a dispute makes no sense. Any legal issues or official complaints are handled through the appropriate authorities or legal channels within the jurisdiction of Costa Rica.

I confirm that there is no way to verify Tessera Labs S.R.L as a registered entity in Costa Rica. And except for this thread, there no mentions anywhere online about a casino called solflash. According to whois domain lookup, the solflash domain is newly registered for only one year duration:
Domain: solflash.bet
Registered On: 2026-08-02
Expires On: 2027-08-02

I don't think this is a trusted casino and i advice to avoid using it. Overall, it is never recommended to connect a personal wallet to a third part service.

As I wrote in the post above yours, all companies registered in Costa Rica can be confirmed on the official Costa Rican National Registry website (Registro Nacional de Costa Rica): https://www.rnpdigital.com/
The company registered under number 3-102-969810 exists:



The above information is available for free. Detailed information, including physical address, must be purchased for a small fee on the same website.

[Solflash_bet]

Fair questions, and I'd rather have them now than not. Let me go through each one. And if reading all this is a pain, I'm happy to just show you: hop on with me, we place a small bet and look at the transaction and the fairness on Solscan together.

The thing most people miss at first is that Solflash is non-custodial. No deposit, no account, no balance sitting with us, and we never see your keys. You play from your own wallet and you sign every bet yourself. We can't move your funds, we literally don't have the ability to. So the "casino vanishes with everyone's deposits" story just can't happen here, there's nothing on our side to vanish with.

And you don't have to take my word for it, it's all on-chain:

• the program: 4rBCVPMsVrxUBCmh8MuK4nR7beBAz7j5rAW3xNiaxBfh
• every bet and payout is a public tx on Solscan
• provably fair: the server seed is hashed and locked in before you play, then revealed after, so you can check the result wasn't touched

On the company, TheAndy500 got it right, thanks for that. It's Tessera Labs S.R.L., cédula 3-102-969810, registered in Costa Rica, and you can look it up in the national registry at rnpdigital.com. The address on file is through our corporate service provider, which is normal for this kind of company, it was never meant to be a walk-in office. And no, those tessera-labs .com/.ai/.info sites aren't us.

On licensing, I'm not going to pretend. Costa Rica doesn't hand out online gambling licenses, so nobody operating out of there has one. That's the whole reason we built this on-chain, you don't have to trust a license, you can verify every bet yourself.

Domain's new, yeah. We registered it in August and we're launching right now, this thread is part of that. New doesn't mean scam, and the difference here is you don't have to wait and see, you can check all of it today.

Last one, on connecting a wallet: connecting to a dApp isn't the same as handing over your coins. You approve each transaction one at a time, you can revoke the site whenever you want, and if you'd rather keep things separate just use a burner wallet to play. The bets are also built so the site can only ever ask you to sign a bet, never some blanket transfer.

Anyway, appreciate the digging, seriously. Come try it with a small amount, verify a bet on Solscan, and tell me what you think. Feedback (good or brutal) is exactly what I'm here for. Happy to jump on a demo anytime.

You should have to know that registering a domain for just one year in not that professional and can be considered a red flag for several reasons:
- The majority of scam websites register domain for one year only because the avoid to spend more money for a useless period. The minimum to purchase is one year and this is enough for them because it can be shut down or closed because of complaints being a scam.
- The online gambling sector is a huge industry that requires huge budgets for development, licensing, marketing... When a website fails to pay few extra dollars to reserve a domain for 5 years at least, it indicates that the project is not serious or it is financially unstable which are weakness points.
- You should have known that search engines, such as Google and bing, takes into consideration the domain age for SEO. Websites with low domain duration are classified as spam or untrusted. I don't think you are satisfied with this.

Fair point, and I actually agree with it, so I just went and extended it. The domain's now registered through August 2030, not a single year. Whois should reflect it shortly once it updates.

Honestly it was just me moving fast at launch, not some exit plan, but you're right that a one-year reg sends the wrong signal. Fixed now. Appreciate you flagging it, that's the kind of feedback that actually makes this thread worth having.

Yes i see it updated in Whois until 2030. It hasn't cost you more than $100. I guess this will help boost the optimization through search engines but you have to focus on marketing inside and outside bitcointalk. Now you cleared details about licensing and domain status, we want you to clarify about your marketing strategy since you chose bitcointalk to start with. It won't be an easy mission here to advertise your casino because of the higher competition.

Decent ANN presentation though the site design itself could use improvement. Your licensing information is fine despite the license provider being one of the less popular ones and I like the whole low RTP structure of your original games basically.

However, without great promotions and VIP rewards, your site won't be able to compete with other crypto gambling sites. For example, Frogbet offers similar low RTP originals with great promotions and rewards. All the best.

From the name it is clear Solflash.bet accepts only soles, but will this precisely narrow the gambling space? I just see that multichain crypto casinos are much more giving nice growth from all directions. For example I only have BTC, ETH, TRX, BNB, and DOGE, then the multichain casino provides all deposit options, but in Solflash I obviously can not gamble, because only SOL.
This may be a stupid statement from me, but based on the gambler's eye, that's the general problem when looking at non-multichain casinos.

Welcome to the forum Solflash team. It seems Solana's gambling ecosystem has been growing bigger everyday. Lots of Solana based online casinos have been popping out lately.
Just out of curiousity, do you guys have any plans to run any promotional campaign here in this forum? If yes, kindly check out the pm I sent about it. I would love to help you guys out.

Appreciate the honest read, that's useful.

Quick thing on the Frogbet comparison, because the core difference gets lost and it's the whole point of Solflash.

Almost every crypto casino, Frogbet included, is custodial: you deposit, your money sits with them, and from there you're trusting them to keep paying, not to freeze your account, and to still be around tomorrow. You send a withdrawal request and hope it clears.

Solflash isn't that. You interact with the smart contract directly, and in plain terms that means:
- Your money stays in your own wallet until the exact moment you place a bet. Nothing is ever held with us.
- The odds and payouts are written into the contract. They can't be changed on you after the fact, and anyone can read them.
- When you win, the contract pays you on the spot, automatically. No withdrawal to request, no approval, no support ticket.
- We can't freeze you, cancel a payout, touch your balance, or run off with a cashbox, because there is no balance and no cashbox. There's simply nothing on our side to take.
- Every bet is a public transaction you can verify yourself on Solscan.

That's what I'd weigh way above the storefront. It's a different model, not just a different site.

On promotions, you're right we're lean for now, but that's tied to the model, not an oversight. The games are our own and settle on-chain, so overhead is tiny, and that shows up as a genuinely low edge on every bet (up to 99% RTP) instead of a flashy bonus quietly funded by a worse one. A proper rewards layer is coming, I'd rather build it right. Design too, fair point, we'll keep sharpening it.

Thanks for taking the time.

This may be a stupid statement from me, but based on the gambler's eye, that's the general problem when looking at non-multichain casinos.

Fair point, and you clearly know your way around crypto, so I won't run you through a "how to get SOL" tutorial. For anyone newer reading with the same question, it's a one-minute swap (in-wallet on Phantom or Solflare, or sell a little on any exchange and withdraw SOL). That part's easy.

The more useful answer to your actual point: Solflash is SOL-only because the casino itself is a smart contract deployed on Solana. The games, the odds, the payouts, it's all code running on-chain, not a website that takes your coins and keeps score. That's what makes it non-custodial and verifiable, and it's why it runs in SOL.

It's also why "multichain" is usually the opposite trade. To genuinely be multichain you'd have to rebuild and redeploy that whole contract on every chain, so most multichain casinos don't, they just custody your deposits across chains instead. You get breadth, but you're back to trusting them with your funds. We went for one chain done natively over many chains done on trust.

So the SOL requirement isn't really a wall, especially for someone like you, it's a quick swap. What you get for it is a casino that never holds your money in the first place.
