Request for feedback: ospex.org decentralized sports speculation dApp

[vincelaird]

Greetings, I'm seeking feedback and early adopters for a decentralized application deployed on Polygon, ospex.org.

The dApp allows you to "speculate" on the outcome of sports contests with just a crypto wallet.  There's no sign up process and there's no fees associated with speculating other than blockchain fees (IOW: no vig).  However, because of this, odds are not fixed, but rather determined by way of parimutuel pools (similar to horse racing odds).

The project is open source and all deployed contracts are verified on chain.  You need USDC tokens and MATIC tokens for gas and these tokens need to be on Polygon Mainnet.  There is currently a 10 USDC limit per speculation, because the contracts have yet to be audited.

I created a speculation on tonight's NBA game, Boston -9.5.  I put 10 USDC on each side so there's something already in the pool.  I would love it if some folks on here would try it out and provide feedback in this thread.  Feel free to put USDC on both sides, so you're guaranteed to win and can therefore verify that claiming works.

If anyone wants to know more about the technical details, just ask.  I think it looks better on mobile and I generally use Metamask, though desktop should work also.  If you have issues using it, let me know here or DM me.  Thanks so much!

No offense but you will have a hard time finding to try your casino using their money even though they bet both side because it’s hard for us to check the smart contract you are using.

I suggest that you run a review campaign in the services board and offer a reward for the trial while you are the one who will provide the money for testing. This way you can gather valid feedback without someone questioning your project credibility.

You should at least improve the background rather than plain white to make it more lively even though it’s on trial phase.

Thanks!  I appreciate the input, will definitely post in Services as that looks like a more appropriate forum for something like this.

I agree with what was said by: @Eternad, the only way to review the ospex.org site is that it works well with its users, you hire those here who have a good reputation and make a review about ospex.org, that way at least the user knows the many experiences that occur when reviewing the ospex.org site, working well or not.

Even though you say this.

Ospex is characterized by its no fee / low fee structure, anonymity, and unrestricted access. It's designed to offer a transparent and fair environment for sports speculation.

But from my review, about this.

1. No Vig
Pay only blockchain fees to speculate; these fees tend to be around 0.01-0.02 USDC per transaction.

2. No Signup
No need to create an account or provide personal information; only a crypto wallet is required.

3. No Limit*
Speculate without concern for being banned, limited, or having your account closed.

*10 USDC limit in place until contracts are audited.

In my experience, what I have seen and found is that points 2. No Signup and 3. No Limit* are vulnerable.

Point 2 at any time the site can no longer be accessed, because the registration security level is low, only connected to the wallet, the risk of logging in at a later date is risky.
Point 3 on the other hand, blocking, or easy closing, the factor refers to point 2.

That's my input, it's best to change this feature to be safe and reassuring.
