Build a Solana Lottery Dapp

[@judevector]

This video is even more educating and helpful for beginners than the main solana playlist. After going through the solana playlist. I had to pause to look for this video because it will teach you well as a beginner

[@user-dz6zd9zk2f]

[@Studyboi-ut7jp]

[@Complxculture]

Hey let’s connect… currently building one

[@_D3adB0y_]

Just went through and built this. Awesome job explaining it for noobs like me. Some issues though: You can Create Lottery after a Winner is Picked and before they Claim it. So it ends up removing the claim ability for the users. Ideally we would have a claim button on the table next to each lottery so players can claim from past lotteries. Also they should be able to enter ongoing lotteries instead of just the most recent one. So adding a button to the table to enter the lottery if it hasnt finished yet would be good, or just make a whole grid of lotteries they can enter with a table at the bottom with the lotteries that were finished already.

I love a dapp

[@isomen9617]

are there github repo for this project would like to examine the code to get better understanding

[@TheOmfg02]

Do we have to use quicknode? can't we just develop on top of the devnet and use their rpc?

[@cheddasol]

can this work with any token on Solana or just SOL ?

[@zboobafett5984]

i haven't watch til the end of the video, but after some troubleshooting i believe your memcmp code was not working because the library import and offsets were incorrect. Here was what i changed to get this to work in context.js: Changed: import { bs58 } from "bs58"; to: import bs58 from "bs58"; //this resolves an error where "encode" was not found or something like that. Changed offset for memcmp for lotteryId should to 44, Changed offset for memcmp for wallet.publicKey to 12 Offsets calculated as follows in terms of bytes: 8 bytes - anchor discrinoator 32 bytes - Account primary key (in troubleshooting i realize this should be excluded from the offset calculation) 4 bytes - Ticket account data field "id" 32 bytes - Ticket account data field "authority" (to reach this field it woul dbe 12 bytes offset, or 8 + 4) 4 bytes - Ticket account data field "lotteryId" (to reach this field it would be 44 bytes offset, or 8 + 4 + 32)

[@ramsey-h7k]

Thanks for the forecast! I have a quick question: I have a SafePal wallet with USDT, and I have the seed phrase. (air carpet target dish off jeans toilet sweet piano spoil fruit essay). How should I go about transferring them to Binance?

[@meka4996]

[@burnafterlaughing]

[@_D3adB0y_]

Who tf thought rust was a great language to use for Solana programs. So damn complicated to do something simple. No wonder Thirdweb dropped support for this chain

[@TikTokTrendsCompilation]

because rust is enough low level language to make fast transactions. but i think golang would be a better choice. rust is boring but not hard to learn

[@Sulanaonsol]

Code please

[@suryakantgupta9185]

Make Duolingo clone please
