SOVEREIGN ZK-ATOMIC SWAP IMMUTABLE GROTH16 PRIVACY-SWAP ENGINE FOR TRUSTLESS OTC EXCHANGE Project Details Research Focus: Improving Proof of Work (PoW) efficiency and cross-chain confidentiality via zk-SNARKs. The Groundfloor Opportunity: This project represents a unique opportunity to lead the research and implementation of ZK-SNARKs on a nascent PoW chain. We are aiming to achieve what Zcash did for privacy and what Bitcoin Cash sought for utility, but at a "Groundfloor" level on a Sovereign EVM. As a lead architect, you will not just be coding; you will be officially improving the Bitnet Money blockchain's privacy infrastructure, establishing a reference standard for trustless OTC exchange before the ecosystem scales. Introduction: Polygon proved that you could take the...

Rivwake is an ambitious early-stage Web3 metaverse project built on Unreal Engine 5. We are creating Overworld — a next-generation immersive metaverse where players can play, create worlds, games, and assets without coding (strong UGC focus). The first game is Strifest — a team-based arena shooter with building mechanics. The project combines high-quality UE5 gameplay with real blockchain integration: NFT rewards, staking mechanics, token systems, and true digital ownership. Company is registered in the UAE. We are currently in the active alpha stage and actively scaling before the token launch. Who We Are Looking For Web3 Game Developer (UE5 + Blockchain & Smart Contracts) Key Responsibilities: Integration of Web3 features into Unreal Engine 5 game (wallet connect, NFT mi...

Here is what we are looking at: We have an existing token (GrokFANS) on the BNB Smart Chain with a built-in 30% tax protocol. We need a DApp that automates and visualizes our multi-tier referral rewards (10% for Builders, 5% for Leaders). The Task: Build a high-performance, mobile-responsive Dashboard (optimized for Trust Wallet) where our users can: Connect their wallets. Generate unique referral links. Track their "Builder" and "Leader" rewards in GrokFANS Tokens. View a "Tree" of the holders they have onboarded. Technical Requirements: Frontend: React.js / with Tailwind CSS. Web3: or Web3.js. Smart Contract: Integration with our existing BSC contract (Solidity). Backend: A lightweight database (Supabase or Firebase) to map referral links to wal...

I’m building an automated model that scans Solidity code on the Ethereum network and flags three critical weaknesses—reentrancy, arithmetic overflow/underflow, and access-control flaws. What I need from you is a working detection engine: it can be rule-based, machine-learning, formal-verification driven, or a hybrid, as long as it reliably pinpoints those issues in typical ERC-20/721 style contracts and produces a clear, human-readable report. I’ll provide sample contracts (both vulnerable and safe) so you can tune precision and recall; feel free to augment with publicly available datasets such as SWC Registry examples. Because this is Ethereum-only work, please focus on Solidity syntax quirks, common library usage (OpenZeppelin), and the nuances of the EVM. If you le...

I’m spearheading a new B2B payments rail that lets African businesses move seamlessly between crypto and local fiat. The immediate milestone is a production-grade, multi-chain wallet layer covering BTC, ETH, SOL and stable-coins such as USDT/USDC across ERC-20, TRC-20 and BEP-20. , Solidity or Rust will be your main playground because some smart-contract glue code and low-level services will emerge as we scale. Core wallet requirements • Cross-chain transactions that feel instantaneous to the end user • True multi-currency balances under one address book • Enhanced security: MPC architecture reinforced with two-factor authentication by default and biometric verification for high-value flows. Beyond the wallet, you’ll own the crypto ↔ fiat on/off-ramp ...
