Blockchain developer Solidity

Nyoka is seeking a Blockchain developer specializing in Solidity to build a sophisticated NFT leasing system. The role involves designing and implementing three interconnected smart contracts that enable NFT holders to monetize their collections through synthetic token rentals without sacrificing ownership rights.

• Develop CoreNFT contract (ERC-721) with fixed supply of 10,000 and reserve pool management
• Build SyntheticToken (ERC-20) with rental logic, lease expiration, and restricted transfer capabilities
• Implement MintCreditVault module with burnForMint functionality and supply cap enforcement
• Design and code payRent, effectiveBalanceOf, and terminateLease functions
• Develop multi-sig wallet integration for security
• Create Telegram/WhatsApp bot for alerts and monitoring (collection price, liquidation risk, gas fees)
• Build position dashboard for tracking rental positions
• Integrate with external DeFi platforms (Arcade, BendDAO, NFTfi) for vault lending

• Expert-level Solidity programming and smart contract development
• Deep understanding of ERC-721 and ERC-20 token standards
• Experience with DeFi protocols and collateral management systems
• Proficiency in contract security patterns (ReentrancyGuard, access controls)
• Knowledge of multi-signature wallet implementations
• Familiarity with NFT marketplaces and lending platforms
• Understanding of blockchain economics and rental/leasing models
• Experience with mainnet deployment and contract auditing

Remote position. The project follows a phased launch approach, starting with small test volume and scaling gradually. Involves working with existing mainnet CoreNFT contract (ExposedWalls Banksy) and requires coordination with owner Wayne through multi-sig governance structure.
