coin-flip's Introduction

CoinFlip (Solana)

Demo

https://sol-coinflip.vercel.app/ -> Runs in devnet Run

Provable Coin Flip Program on Solana.

The app consists of a vendor and a player.

Player triggers a coin flip game by selecting side and the amount of SOL to bet.
Vendor creates a CoinFlip game on-chain and saves the bet of the user and sends the equal amount of SOL to CoinFlip PDA. In this step, vendor generates a random seed to be used in the coin flip.
When the CoinFlip account is created, user generates a random seed and sends approves the Play transaction by sending the bet amount to CoinFlip PDA.
Play function will combine the vendor hash, player hash and the current timestamp to flip the coin. This way, not a single participant can influence the result as the seeds are aggregated from different sources.
CoinFlip account sends the amount to the winner, logs the events and closes the account.

Webapp

Webapp is generated using Next.js and Solana Wallet Adapter.

Running the app

Start the local Solana validator
Deploy the app to local cluster with anchor deploy
Go to the app directory and run npm run install
Run the app with VENDOR_SECRET_KEY env variable. You can use any keypair as the vendor. Example: VENDOR_SECRET_KEY=[12, 232,1231 ...] npm run dev

stop on Status: Generating a random seed

after play the game not showing the result ??

api problem :
API resolved without sending a response for /api/setup, this may result in stalled requests.

https://sol-coinflip.vercel.app/ not working

Hello, I am getting an error playing the game on your website. The message it displays after I click "Play" first says "Generating Random Seed" and then says "Status: Something went wrong, please try again." Is this on your end or my end and how can this be fixed?

Any help would be appreciated, thanks.

I got issue when tried to run the app

and how to do this command "Run the app with VENDOR_SECRET_KEY env variable. You can use any keypair as the vendor. Example: VENDOR_SECRET_KEY=[12, 232,1231 ...] npm run dev"

Tried with "VENDOR_SECRET_KEY=[12, 232,1231 ...] npm run dev" ofc i have changed the Vendor Value, but it said "VENDOR_SECRET_KEY COMMAND IS NOT FOUND"

please make a full tutorial about this project :) i'm new at deploying smart contract

help pls?

Hey any chance you can update readME file and show each command to run to get it going?? Would be amazing!

Add Switchboard VRF

Adding Switchboard VRF instead of timestamp would be a more secure method.

Unhandled Runtime Error TypeError: _project_serum_anchor__WEBPACK_IMPORTED_MODULE_2__.Provider is not a constructor

Small Issue with program.rpc.play

Hello @venture1981, sorry to bother you mate.. I've just run into a small issue.. Using anchor test.. everything works out smoothly and there are no issues.. however when I deploy the contract and try to use the dev-net I run into this issue:
When the user/player is supposed to sign the transaction after the setup.. it throws the error I showed above.. and given I'm pretty new as to how this works.. I'm struggling to figure it out.. the vendor doesn't need to sign the transaction right?

any help would be very appreciated. Thank you for your time.

Wallet Detection

Hello,

Was running this on linux server and devnet, it would run but would not detect the solana wallet. Not sure if it is because of the VENDER_SECRET_KEY, not sure how to use this command. Any help would be appreciated, thanks.
