The right stack depends on the chain, the assets and who holds the keys. Blockchains - Ethereum - Solana - Aptos - BNB Chain - Polygon Smart contract languages - Solidity - Rust - Move Development frameworks - Hardhat - Foundry - Anchor - OpenZeppelin Custody and wallets - Fireblocks - MetaMask - WalletConnect Oracles and on-chain data - Chainlink - The Graph Frontend integration - ethers.js - viem - wagmi ## From idea to launch. Four stages, with a working version reviewed at each one. ### Discovery Map the product, the systems and data involved, and what good looks like. Discovery notesDone - The product and its users - Chains, custody and compliance needs - Launch constraints ### Scope & architecture Agree the architecture, success measures and delivery milestones. Solution designDone - Architecture and chain choice - Security and audit plan - Delivery milestones ### Build Build against real data, with a working version reviewed at each milestone. Working buildDone - Contracts and platform built - Audit findings closed - Review at each milestone ### Ship & support Roll out to production with monitoring and a defined support window. Production rolloutDone - Launch - Monitoring and uptime - Defined support window ## Why Avinya for Web3. Shipped, audited and still running. ### Launch-ready timelines A centralized exchange in 20 weeks and stablecoin rails in 5, on delivered engagements. ### Security before launch Contracts audited and every finding closed before deployment. ### Built to stay live 99.9% uptime since launch on our exchange build. ### Compliance from day one KYC/AML and regulatory considerations are part of the architecture, not a retrofit. ### Regulation-aware token design Token economies designed to hold up under financial regulation. ### Web3 and AI under one team One studio for on-chain infrastructure and, where it helps, AI systems. ## Results from our Web3 work.

Centralized exchanges, smart contracts and dApps, stablecoin payment rails, wallets and custody, and token economies for real-world-asset platforms. ### How long does a Web3 build take? It depends on scope. For reference, we delivered a centralized exchange in 20 weeks and stablecoin payment rails in 5. We agree milestones up front. ### How do you handle security? Contracts go through a full audit before launch and every finding is worked through before deployment. Our most recent audit launched with zero critical findings. ### Which chains do you work with? We choose per use case after comparing chains, custody and infrastructure options. Our smart contract work has shipped across multiple chains. ### Do you handle compliance? We build KYC/AML into onboarding and design token economies with regulation in mind. Legal sign-off stays with your counsel. ## Ready to turn your vision into reality?
