AmonixPlay is our flagship multi-chain Web3 platform that blends AI-driven logic, robust blockchain security, and Play-to-Earn mechanics. I’m now expanding the development team with someone who lives and breathes blockchain scalability, particularly cross-chain interoperability. Your focus will be hands-on development. I already have high-level architecture and business logic in place; what I need is code that lets assets and data move seamlessly between chains without bottlenecks or security gaps. You’ll work in a remote-first environment where schedules are flexible and contributions are measured by the quality and reliability of what ships to production. Key objectives you’ll tackle: • Build and optimise cross-chain bridges or messaging layers that plug into our existing smart-contract suite. • Write clear, audited smart contracts (Solidity, Rust or similar) that minimise gas fees and latency. • Integrate your work with our AI-powered fairness engine and P2E reward system. • Collaborate with QA to create automated tests that validate transaction integrity in real time. • Document modules thoroughly so future contributors can iterate without guesswork. Acceptance criteria: • Demonstrable cross-chain transfers completing in under five seconds on our staging network. • Full unit and integration test coverage with >90% line coverage. • Security review passed by an external auditor. The stack leans on EVM chains, Cosmos SDK, and Substrate-based networks, so fluency in at least one of those ecosystems is essential. Experience with L2 roll-ups or sharding is welcome, but interoperability know-how is non-negotiable. If building the rails that let a global gaming economy scale excites you, let’s talk timelines and milestone cuts so we can get your code merged and shipped.

Hi there! Building a secure and fast cross-chain infrastructure is one of the biggest challenges in Web3, especially when scalability, low latency, and transaction integrity are critical. You need someone who can develop reliable interoperability layers without creating security risks or performance bottlenecks. I have experience working with blockchain development, smart contracts, and multi-chain integrations across EVM-compatible ecosystems. I’ve worked on Solidity-based contracts, bridge integrations, gas optimisation, and automated testing for secure transaction handling. I also understand the importance of audit-ready code, documentation, and scalable architecture for long-term Web3 platforms. I can help build and optimise cross-chain communication layers that integrate smoothly with your existing smart-contract suite. The focus will be on low-latency transfers, efficient gas usage, and secure contract architecture with strong testing coverage. I can also collaborate closely with QA teams to implement automated integration and transaction validation testing. All modules will be properly documented to support future development and easier maintenance across the platform. check our work https://www.freelancer.com/u/ayesha86664 Which interoperability protocol or bridge framework are you currently planning to use within the AmonixPlay ecosystem? Let me know if you’re interested & we can discuss it. Best Regards Ayesha

Hello, I’m Cora May, I'd love to help expand AmonixPlay’s multi-chain rails for your AI-driven fairness engine and Play-to-Earn economy. I’ve built and optimized cross-chain messaging/bridge components that move assets and state with a focus on security, replay protection, and predictable latency, and I integrate cleanly into existing smart-contract suites. For your stack (EVM, Cosmos SDK, Substrate), I can implement audited smart contracts in Solidity and/or Rust, minimizing gas while keeping verification logic explicit to reduce attack surface. I’ll also wire the transfer flow into your reward and fairness logic so transaction outcomes remain consistent across chains, then collaborate with QA on automated integrity tests that validate behavior in real time. Finally, I document modules thoroughly so future contributors can iterate without guesswork and so your external auditor has a clear trail.

Hello, I can help build and optimize the cross-chain bridge and messaging layer for AmonixPlay using Solidity, Rust, smart contracts, and blockchain integration. I have experience building scalable backend systems, AI workflows, and production-ready integrations where reliability, testing, and documentation matter. Your focus on secure asset movement, low latency, and P2E reward integration matches the kind of hands-on engineering I enjoy. I’ll work with your existing architecture, write clear smart contract modules, integrate with the AI fairness engine and reward logic, and support QA with automated unit and integration tests targeting strong coverage and transaction integrity. I am ready to start and can work in milestone cuts toward staging transfers, test coverage, and audit readiness. Could you share the current smart contract repo and which chains are first priority for the bridge? Best, Smit
