Web3 Blockchain Developers for Saudi Vision Projects

Design and build AMMs, order books, cross-chain DEXs, and liquidity protocols with a focus on secure smart contracts, gas optimization, front-end wallet flows, and integrations with liquidity aggregators. We implement Solidity patterns, on-chain settlement logic, bridges and subgraph indexing, plus security testing and audits to ensure resilient DeFi systems that scale under load and comply with industry best practices.

Develop full-featured NFT marketplaces and minting platforms supporting ERC-721 and ERC-1155, lazy minting, royalties, auctions, fractionalization and metadata storage on IPFS or Arweave. We handle minting gas optimizations, custody and marketplace UX, payment rails integration, creator royalty enforcement, and The Graph indexing for fast discovery and filtering of assets.

Implement wallet integrations and build custom wallet solutions, handling MetaMask, WalletConnect, RainbowKit and mobile wallet browsers, account abstraction patterns, secure key management, transaction batching, gas estimation and EIP-1559 strategies. We design session management, UX flows for signing, and multi-chain connectivity to simplify complex wallet interactions for end users.

Create governance frameworks, proposal systems, on-chain voting modules, timelocks, delegation and quorum mechanics, plus off-chain tooling like Snapshot integration and on-chain vote execution. We build intuitive governance interfaces, proposal lifecycle management, role-based access and security checks to ensure transparent, accountable decision making for decentralized organizations.

Build game backends and on-chain asset systems for blockchain games and metaverse experiences, including composable NFTs, token economies, low-fee sidechain integration, real-time synchronization with off-chain servers, and secure in-game marketplaces. We focus on performant UX, asset provenance, item composability and scalable infrastructure for immersive play-to-earn ecosystems.

Develop decentralized social platforms and identity solutions using Sign-In with Ethereum, DIDs, verifiable credentials, reputation systems and privacy-preserving identity flows. We implement content storage strategies, moderation tools, wallet-based authentication, and federated identity patterns to enable trusted, user-owned social experiences that respect data sovereignty.

Integrate IPFS, Filecoin and Arweave for permanent storage and build analytics pipelines with The Graph and custom indexing to surface on-chain events. We deliver dashboards and real-time sync between on-chain and off-chain data, cost-aware storage strategies, and queryable subgraphs to enable actionable insights and robust data layers for DApps.
