Project Brief — Fully-Automated Hourly Jackpot (Solana) Please share a SolScan link to a Devnet or Mainnet smart contract interaction you personally built. Without this proof, I can’t consider the bid Overview A fully automated, on-chain jackpot that rolls every 60 minutes for a Solana token, viewable in a simple web browser UI. Round Flow • A fresh round starts every hour with a live 60:00 countdown. • The program silently commits a random secret cutoff chosen between 55:00 and 10:00 remaining. • For every wallet, only its last qualifying buy after its last sell counts (“last buy wins”). • When the timer hits 00:00, the ten largest qualifying buys (before the secret cutoff) are revealed and the jackpot — exactly 50% of that hour’s Creator Rewards — is split evenly among them. • All payouts execute on-chain instantly, followed by an immutable proof package: cutoff timestamp, winning transaction hashes, and payout hashes — all linkable via SolScan. • The next round begins automatically with no human trigger. Key Requirements • On-chain program (Rust/Anchor or equivalent) enforcing: • “Last buy wins” state, • commit-reveal cutoff (VRF preferred; commit-reveal acceptable), • winner selection (top-10 by amount; tie-break = earlier timestamp), • equal distribution of the jackpot. • Lightweight web front-end (React/[login to view URL] or similar) showing: live timer, current pot, user’s personal qualifying buy, and proof archive. • Keeper/automation (bot/cron) that triggers only the reveal transaction; all other logic remains deterministic on-chain. • Transaction-monitoring hooks for anomaly alerts. • SolScan links wired throughout for transparency. Deliverables 1. Auditable Solana program with unit tests. 2. Deployment scripts and env configuration. 3. Web front-end integrated with the program. 4. Keeper/automation script with fail-safe restart logic. 5. Documentation covering setup, env vars, and proof workflow. Acceptance Criteria (Devnet demo) • One full live cycle: start → hidden cutoff → winner selection → on-chain payouts visible on SolScan → automatic next-round start. • Proof package published and verifiable. (Optional but recommended to include) • Minimum qualifying buy: e.g., >= 0.05 SOL to ignore dust. • If <10 winners (e.g., low activity), split equally among eligible wallets.

Hello Bob, I am proficient in developing Solana-based smart contracts using Rust and Anchor, and I have experience with on-chain games, especially jackpot systems. I can create a fully automated jackpot game that meets your requirements, ensuring a seamless user experience with an intuitive web front-end built on React or Next.js. The implementation will include a deterministic program that efficiently handles the "last buy wins" logic and utilizes VRF for the commit-reveal mechanism. I will ensure that the jackpot distribution is transparent and verifiable, integrating SolScan links throughout the application for accountability. Additionally, I will provide comprehensive documentation and setup scripts, ensuring easy deployment and an auditable codebase with unit tests. A keeper mechanism will be established to automate the reveal process while safeguarding against failures. Thanks, Teo.

Hello, I have already rich experience in this kind of project. I can show you my past project in private chat. I would detect a buy vs. sell by checking the Solana transaction’s token account changes: if the user’s balance of the jackpot token increases from a DEX swap it’s a buy, and if it decreases it’s a sell. I am ready to start right now. Waiting for your reply.

⭐Hi, I’m ready to assist you right away!⭐ I believe I’d be a great fit for your project since I’ve built Solana smart contracts with Anchor and connected them to clean, responsive web UIs before. I know timing, fairness, and transparency are critical in your jackpot system, and I can design the on-chain program to enforce “last buy wins,” commit-reveal cutoff, and fair top-10 winner selection while keeping everything deterministic and secure. I’ve also delivered automated keeper bots and monitoring hooks that ensure round cycles run hands-free, with on-chain proofs published for full auditability. Your project solves a big problem: manual jackpot draws are prone to human bias and downtime, but a fully automated on-chain solution guarantees fairness and transparency. This gives your users confidence while keeping the system efficient and self-sustaining. I’m used to delivering on tight timelines and within budget, with clear unit tests, deployment scripts, and documentation so you can easily manage future updates. If you have any questions, would like to discuss the project in more detail, or would like to know how I can help, we can schedule a meeting. Thank you. Maxim

Hello, I understand you want a fully automated on-chain jackpot on Solana that runs every hour with provable fairness, instant payouts, and full transparency via SolScan. The goal is a trustworthy game where users clearly see the rules, the proofs, and their winnings without human intervention. I will deliver a reliable Solana program with “last buy wins” enforcement, hidden cutoff logic, and automatic payout distribution. Key risks include the fairness of randomization, edge cases where fewer than ten winners qualify, and downtime in automation. I mitigate these with verifiable randomness or commit reveal, strict on-chain state checks, and keeper scripts with restart safety. If this aligns with your vision, I will break it into clear milestones so you can test each stage from Devnet through to full deployment. Best regards.

Hi there, Do you prefer a VRF-based randomness (Chainlink/Switchboard) or a commit-reveal scheme to satisfy auditors, and do you want a minimum qualifying buy (for example 0.05 SOL) to ignore dust? I like your plan to build a fully automated hourly Solana jackpot that is transparent, auditable, and hands-off. I can author a Rust/Anchor on-chain program enforcing the “last buy wins” rule, a commit-reveal or VRF cutoff, deterministic winner selection (top-10 by amount, timestamp tie-break), and equal on-chain distribution of exactly 50% of Creator Rewards. I will add unit tests, on-chain assertions to prevent manipulation, and an immutable proof package (cutoff, winning tx hashes, payout hashes) that links to SolScan. I will also build a lightweight React/Next frontend showing the live timer, current pot, user qualifying buy, and proof archive, plus a keeper script that only triggers the reveal transaction and includes fail-safe restarts and anomaly alerts. Deliverables will include deployment scripts, env configuration, a Devnet demo cycle, and clear documentation for auditors and operators. I have experience shipping audited Solana programs and automation tooling, and I can prioritize security and transparency for this project. Hope to discuss more on chat. Best, Toma K.

Hi, I can deliver a robust automated Solana jackpot game with all the required features. Here’s how I’ll approach it: On-Chain Program: I’ll implement the “last buy wins” logic and ensure the jackpot is fairly distributed among the top-10 largest qualifying buys, using VRF or commit-reveal methods. The on-chain program will include transaction monitoring and anomaly alerts for full transparency. Web Front-End: A clean, simple UI will display the live countdown timer, current jackpot, user’s qualifying buy, and an archive of proof packages. The frontend will integrate seamlessly with the Solana program using React/Next.js. Automation: I’ll implement a keeper/automation script that triggers the reveal transaction and handles fail-safe logic to ensure a smooth user experience. Auditable System: The entire process will be auditable via SolScan links, ensuring complete transparency for users. I’ll also include unit tests, deployment scripts, and detailed documentation. Devnet Demo: One full live cycle will be demonstrated, including winner selection, on-chain payouts, and proof package publication.
