I’m running a production Solana trading bot that trades tokens pre- and post-bonding curve. Version 1 is live. I’m hiring to build Version 2, focused purely on latency, throughput, and execution efficiency. This is NOT a general Solana dev role. This is infra / MEV-level engineering. If you haven’t built low-latency, high-throughput Solana systems in production, do not apply. Scope (High-Level) Aggressive transaction fee + execution path optimization Minimize frontend + backend latency Scale RPC throughput 10 rps → 100–250 rps Bulk transaction execution at high frequency Avoid / mitigate Jito Bundler detection Efficient account & sub-account creation at scale Detect → DEX migration and automatically switch execution to: Jupi...

I’m assembling a freelance roster of seasoned Solana engineers to push a new decentralised application from idea to mainnet. The role centres on end-to-end DApp development: writing and auditing on-chain Rust programs, wiring them to a TypeScript/React front-end through Anchor or @solana/, and handling deployment, testing and optimisation so the final product is fast and fee-efficient. If you have shipped production Solana work before, please include links or GitHub repos that clearly show what you built and the parts you owned. I’ll review those examples first to decide who moves forward. We will work milestone-by-milestone; as soon as the initial scope is delivered (fully functional features, commented code, concise hand-off docs), I have follow-up task...

I maintain a Node.js / TypeScript code-base that submits Jito bundles to the Solana network at high frequency. The current version works, yet under heavy load it saturates network bandwidth, slows slot confirmation, and leaves a larger attack surface than I’m comfortable with. I’d like you to jump in, profile the pipeline, and return an implementation that is measurably better across three axes—performance, scalability, and security. What performance means here is simple: bundles must reach the leader faster so more of them land profitably. I’m especially keen on lowering the chatter between my service and Jito’s relays so network bandwidth is used far more efficiently. You’ll have full access to the existing TypeScript modules, aggregator logic...

Je souhaite lancer un stablecoin entièrement adossé à une devise, émis et géré sur la blockchain Solana. Votre mission couvre tout le cycle de vie technique : • Concevoir et coder le programme SPL Token qui garantit le peg 1:1, y compris les fonctions de mint/burn et les garde-fous nécessaires. • Mettre en place la logique de gestion des réserves (oracle de prix, comptes de collatéral, contrôles de transparence). • Déployer et tester le contrat sur devnet puis mainnet, avec scripts automatisés. • Fournir une documentation claire et un guide d’intégration pour portefeuilles et plateformes d’échange. • Anticiper les bonnes pratiques de s&eac...

I need a Solana-based bot that can execute trades automatically while constantly monitoring trading-volume signals to decide when to enter or exit positions. The core idea is a “monitoring”-style strategy rather than complex arbitrage or high-frequency scalping: the bot should watch real-time volume spikes on chosen pairs and trigger pre-set order actions the moment a threshold is crossed. Key expectations • Continuous stream access to Solana on-chain data (e.g. via WebSockets/RPC endpoints) with sub-second latency • Simple, configurable rules where I can define the target markets, volume threshold, order size, and slippage tolerance • Auto-trade execution through a DEX of your choice (Jupiter, Serum, or Orca are fine as long as you justify t...

I am hiring an experienced Solana and full-stack developer to complete an existing project called ChainHire. ChainHire is a freelancing platform where the platform itself acts as an on-chain escrow using the Solana blockchain. The project is partially completed. Your responsibility will be to finish the remaining features, integrate and secure Solana smart contracts, make the application platform-independent, and deploy it to production. Scope of work includes completing pending frontend and backend features, integrating Solana escrow smart contracts using Anchor, wallet integration with Phantom or Solflare, ensuring cross-browser and responsive behavior, fixing bugs, optimizing performance, deploying both smart contracts and the application, and providing ...

I’m building a decentralized application on the Ethereum network and need an experienced Solidity developer to write, test, and deploy the core smart contract that will power the dApp. The contract must follow best practices for security and gas-efficiency and be ready for mainnet once we complete testing. You’ll start by defining the contract architecture with me, then move on to clean, well-commented Solidity code. I prefer a modern workflow—Hardhat or Truffle for compilation and testing, plus or for interaction scripts—but I’m open to alternatives if you have a strong preference. Unit tests that reach full branch coverage are essential, along with a brief technical write-up explaining the contract logic, deployment steps, and any upgrade or governance co...

I want to launch a brand-new utility token on Solana and need an engineer who can own the entire stack—from the on-chain program right through to a simple web interface where holders can interact with that program. The scope covers everything: architecting and deploying the SPL smart contract, wiring up back-end services (Rust, Anchor, or any proven Solana framework), and shipping a lightweight React or Vue dashboard so users can create, transfer, and manage balances the moment mainnet goes live. A clean, well-commented codebase is essential because the token’s ultimate purpose (staking, voting, or additional mechanics) will grow over time; I’d like the contract written with that future extensibility in mind. You should be comfortable with common wallets su...

I’m looking for someone who already understands the MEV game inside out and can turn that knowledge into a live, revenue-producing system. The scope spans both Ethereum and Solana, so you’ll be juggling Solidity, Rust, Flashbots, and Solana’s priority-fee mechanics in one coherent architecture. Core objectives • A single MEV bot that watches the mempool in real time, identifies opportunities, and automatically executes profitable front-running, arbitrage trading, and sandwich attacks. • On-chain components written in Solidity (for Ethereum) and Rust/Anchor (for Solana) that the bot can call to secure transactions, bundle them, and protect against re-ordering. • Robust monitoring, risk controls, and simple configuration so we can turn in...

I need a lightweight, web-hosted bot that continuously watches chosen Solana tokens and triggers an SMS the moment their price moves beyond a threshold I set. A simple browser dashboard should let me add or remove tokens, adjust upper / lower limits, and see the latest price pulled from a reliable feed (on-chain oracle, CoinGecko API, or similar). Key deliverables: • Responsive web interface for token management and threshold settings • Real-time price monitor running in the background (cron, worker, or serverless function) • Clean, well-commented source code plus a brief README covering deployment and environment variables The goal is lean and fast rather than feature-heavy; as long as the alerts are timely and the UI is clear, I’m happy.

I want a small, self-contained solution that proves ownership of a Solana wallet by signing a personalised text message. The message must concatenate my chosen username and a unique transaction ID—no images or JSON, just plain text. The wallet owner’s private key has to be used for the signature so anyone can later validate it with the corresponding public key/uniquie text. This is a quick work; need a trustable programmer who can handle the wallet information and help add the required text.

I’ve just dropped $HIGHHAF, a shiny new Solana memecoin on , and I need a sharp shiller to light up both Crypto-Twitter and Solana-heavy Telegram channels. Here’s the game plan: • Craft 2-3 punchy, humorous text tweets daily, all riding the $HIGHHAF hashtag. • Whip up at least one fresh image meme every day and sprinkle in short video clips or GIFs whenever possible. • Echo the best bits into key Solana Telegram groups and keep my own chat buzzing with replies, polls, stickers—whatever keeps the crowd engaged. Simple tools like Canva, CapCut, or even in-app editors are fine; the vibe just needs to be funny, fast, and share-worthy. I’m offering $10 upfront plus a cut of any profit if this thing moons.

I need a lightweight web app that lets anyone list a new Solana-based token, attach a payout wallet, and then compete for community votes until a fixed deadline triggers automatic prize distribution to the top-ranked project. Functionality is straightforward: • Two account types: token submitters and voters. • A submission form captures token name, symbol, brief blurb, and the Solana wallet address where any winnings will be sent. • Each voter can cast one vote per token, but holdings of a designated “boost” currency add a multiplier we can configure (e.g., 1 vote + 4× if they hold at least X units). • When the countdown ends, the system tallies results and transfers the prize wallet-to-wallet. • A simple admin dashboard let...

I need a small Telegram bot that listens directly to the Solana chain and pings me the moment any token price spikes on real time (based on my preference) monitoring every 3 minutes Deliverables • A quick live demo on your test channel showing real-time alerts working I’m happy with Rust, TypeScript or Python—use whichever stack lets you tap Solana reliably and keep the latency low.

I’m looking for a mentor-style specialist who can take me through the practical side of launching hype-driven Solana meme coins. My most urgent need is tightening the bot and tool setup—especially a reliable bundle-buy configuration—so that launch-day interest snowballs instead of stalling. Here’s what I’d like from you: • A concise, step-by-step written guide that shows every click, command, and parameter required to spin up a bundle-buy bot on (or the equivalent Solana stack), including any companion volume-tracking scripts you find essential. • A short cheat-sheet I can keep at my desk: common commands, config templates, and troubleshooting tips. • A lightweight playbook of proven community-engagement moves—raid cal...

I’ve launched a few tokens on and now want to level-up the way I handle launch-day hype. I need a hands-on walkthrough of the core tools traders rely on—bundle-buy , volume-tracking bots, and any other lightweight systems that make spinning up a Solana meme coin smooth and viral. My main focus is marketing strategy, especially the kinds of community-engagement tactics that turn early holders into loud advocates. If you have solid, first-hand experience running or advising meme coin launches and can show practical examples of how you used these bots and dashboards to ignite real traction, that’s exactly what I’m after. Deliverables I have in mind: • Live or recorded demo of the bundle-buy/volume bot setup, step-by-step. • A simple cheat-sheet of...

I’m commissioning a custom sniper bot for Solana whose single most important metric is SPEED. The core trading logic has to react to on-chain events in real time, so polling is out of the question—everything must hinge on WebSocket program-log subscriptions. Key capabilities I need built in: • WebSocket-based detection for BOTH and Raydium liquidity pools as soon as they’re created. • Flexible transaction submission that can switch between Jito bundled transactions with priority fees and direct sends through my private Helius or QuickNode RPC endpoints. • Zero-delay execution path from detection to signed transaction; all signing happens locally, the bot never touches my seed phrase. • Adjustable slippage and buy size, with optional ta...

You will be implementing defined components, not inventing the system. --- What You Will Be Working On You will help implement and wire together: Action schema validation (strict JSON, fail-closed) Strategy modules (bounded, deterministic, profile-based) Telemetry aggregation (sanitized summaries ...

...production-ready multi-bridge that enables secure cross-chain communication and cryptocurrency transfers between Ethereum and Solana. The focus is on trust-minimised messaging first, with seamless ERC-20 ↔ SPL token movements as a practical demonstration of the protocol. You should be comfortable writing and auditing Solidity, Rust (Anchor preferred), and designing a lightweight off-chain relayer or oracle layer that keeps both chains in sync without introducing single-point custodial risk. Proven experience with Merkle proofs, light-client verification, or multi-sig threshold schemes will be invaluable. Deliverables • Ethereum smart contracts (lock/burn + message verification) • Solana program mirroring the above logic (mint/release + message verificati...

I need a clean, well-commented Solana Program written in Rust with Anchor that lets me create and manage a new token from scratch. The core requirement is straightforward token generation, but all critical actions—minting additional supply later, burning, updating metadata, pausing transfers—must be limited to an on-chain Administrator role defined in the program. Please structure the code so it compiles and deploys in Solana Playground with a single `anchor build && anchor deploy`, and include a short test or demo script showing the admin wallet exercising its exclusive privileges. A concise README that walks through setup, deployment, and typical admin calls will be the final piece I need to ship this into production.

I've just launched a new Solana meme token (CA inside). Need a street-smart promoter who KNOWS how to flood Twitter/X, Telegram, Discord, and even TikTok with hype. Must hit 50+ accounts (followers >5K) with tweets, 5 solid Telegram groups (1K+ each) AND create a burner account that keeps retweeting it like it's your mom. Bonus if you got crypto friends who actually buy. Budget: sixty dollars. DEADLINE: 12 hours. Prove you ain't wasting my time—send screenshots of past pumps you've done. Let's go. Post it. And if they don't deliver, BANISH THEM. Who's gonna see this first?

I have a CSV with roughly 1,600 entries. Each row holds the post time (in ISO 8601 format, e.g. 2025-01-01 20:56:35+00:00), the chart link, and the token’s initial price. The tokens live on Ethereum, Binance Smart Chain, Solana and Base. What I need is an analysis to visit every chart link, and note the local all time high of the token at the beginning of the post time. You can also automate it by code if you can. • the absolute highest price each token reached after it was called till today • the gain expressed both as “X” and as a percentage over the initial price (3.77x and 277%) • how many days (or hours, if you prefer) it took to hit that high • statistics like: tokens that never managed to trade above the initial price.

I have an ERC-20 / SPL token that already lives on Ethereum, Solana and Binance Smart Chain. The pieces that are missing are the contracts, relayer logic and front-end that let holders move the asset seamlessly between these networks. The core requirement is true cross-chain transfer—no swaps, no dApp interoperability extras for now—just the ability to lock or burn the token on one chain and mint or release it on the destination chain with full proof verification. The existing token contracts are live and verified on each network, so your focus will be the bridge layer itself. This includes: • On-chain contracts (Solidity for Ethereum & BSC, Rust/Anchor for Solana) • A lightweight relayer or oracle component to pass finalized block headers / proo...
