Dapper

I just open-sourced an entire stack for building trustless prediction markets on Solana. No backend. No database. No user accounts. No API layer. Precog Markets is a local-first prediction market platform where everything lives either on-chain or in the user's browser. The Solana program handles all fund custody, market lifecycle, and payouts. The client app talks directly to the blockchain through the user's own wallet. Nothing in between. The full project is three repos: → precog (Solana Program) The on-chain protocol. Pari-mutuel markets with SOL, SPL Token, and Token-2022 support. Creator fees, dispute windows, multisig authority. Deploy your own instance and run a fully independent protocol. github.com/honeygrahams2/… → precog-markets (JavaScript SDK) Instruction builders, account deserialization, PDA derivation, compute estimation, and RPC-agnostic priority fees. Works with any Solana RPC provider. Available on npm. github.com/SolDapper/prec… npmjs.com/package/precog… → precog-app (Frontend) A zero-backend web app built with vanilla JS. Parcel-bundled, mobile-responsive, PWA-ready. Watchlists, saved makers, real-time WebSocket notifications, token gate support, and a full market lifecycle UI from creation to claims. github.com/SolDapper/prec… Why open source all three layers? Because prediction markets shouldn't depend on a company's servers staying online. If our website disappears tomorrow, every market, every position, every dollar is still on-chain and recoverable. Anyone can fork the app, deploy the program, and run their own platform. That's not a tagline. That's the architecture. Built on Solana. MIT licensed. Zero backend infrastructure.

@therealchaseeb SOLANA

If you’re my mutual say SOLANA

@ArtDYOR This is the way

one thing i strongly focused on while buiding is that my app never holds private keys or custody funds. every transaction is signed by the user's own wallet via mobile wallet adapter. even a fully malicious actor who reverse enginers the entire app will find no keys to steal and no funds anywhere.

@metasal 💀

0x cause that’s your return over 5 years

Real talk

@Clive_99 You mean this treatment? 😆

How many more Robinhood nuclear bomb rugs need to happen before we give them the Bonk treatment?

@c4b4d4 @solana_devs 👀 curious

Hey @solana_devs is the minimum amount of SOL a Solana account must hold (0.00089088) changing with the Rent Reduction SIMD? I bet yes, right.

One more hard quarter

Does everyone else have the down vote button on replies already? Am I just now catching up? 🤔

@harkl_ @FwazSol It was time for a change 😁

@SolDapper @FwazSol Doxxed Dapper 👀

Damn A lot of OGAFs around these parts

@FwazSol @harkl_ ⬆️ this 😄

@harkl_ only OGs stayed

@Raydium talent.sol would love that

Who else would love 5.6 SOL?

😂

@solana Technically a few of us kept pushing into 2023. But then SVB collapsed before the money guys closed the seed round and that was a wrap. No regrets.

Since we're in Solana throwback mode I'll share something. In 2021 & 22, a 12 person team including myself were all working on a bootstrapped Solana project called RCN. It was an experimental NFT based crypto REIT/DAO hybrid utilizing quadratic voting and eventually nested collections. When FTX crashed our entire team left the eco with the exception of Helen and myself. Then in Dec 22 you all sucked my into the CT like a $20 hooker, welcomed me the the trenches, and taught me the value of being more involved socially. Like most projects from back then... it died. But I just thought it's worth sharing these old screenshots and maybe somebody will get inspired and build something wild.

@RonDeSantis True, however if common sense was still a viable option at the federal level then we wouldn't even be having this conversation. 🫡

Or — Congress can remedy it legislatively and then strip the courts of jurisdiction over cases involving birthright citizenship for foreigners.

@solana One feature I think about a often: If you wanted to sell a position (nft), you would escrow it into a queue. So then when new contributors would buy in, it would bypass minting and pull it from the escrow queue oldest first and made the NFTs semi-liquid.

@fordudesake I'm thinking I can touch 800 if I can find the damn thing

@SolDapper my oldest i could dig up was like 836 lol

That'll do donkey

@fordudesake And that's just the oldest I have readily available. I'm going to go through some old drives and see what I can dig up.

@SolDapper nice
