Software and apps · delivered in 7-25 days
A production-grade Web3 wallet frontend connecting MetaMask, WalletConnect v2 and Coinbase Wallet across multiple chains, with a DeFi dashboard, NFT gallery and swap interface. Delivery runs from 5 to 25 days, a working preview is ready within 48 hours, and the Basic tier includes 3 rounds of revisions.
We build Web3 wallet frontends that connect to live chains, sign live transactions and hold up once real users land on them. These are deployed, chain-connected applications rather than static mockups or placeholder pages, so they work the moment someone opens MetaMask or WalletConnect v2.
Whatever the brief - a DeFi dashboard, support for several chains, an NFT gallery or a swap screen for tokens - the entire frontend layer is handled: connecting wallets, signing transactions, pulling balances, switching between networks, managing approvals, and covering the error states many projects only discover once live.
Many wallet frontends look fine in a demo but fall over once a user is on the wrong network, holds a zero balance, rejects a signature or hits a dead RPC endpoint. Every state here is accounted for, and error messages are written in plain language rather than raw hex output.
On the frontend: React 19 for the UI, Next.js 15 for routing, TypeScript throughout, Tailwind CSS for styling and Framer Motion for animation. On the Web3 side: wagmi v2 and viem for chain calls, ethers.js v6 where needed, RainbowKit and WalletConnect v2 for connections, and a wallet-adapter for Solana. For data: TanStack Query and Zustand for state, RPC access through Alchemy, Infura or QuickNode, and pricing from the CoinGecko API. Hosting defaults to Vercel, with Cloudflare, Railway or IPFS available as alternatives.
Each build goes through wallet-connection checks spanning MetaMask, WalletConnect v2 and Coinbase Wallet, checked across the main browsers and mobile wallet apps. Network switching prompts, wrong-chain warnings and failed-transaction handling are checked by hand before delivery, and testnet trial runs can be arranged on request.
Full intellectual property and source code pass to the buyer once the project is delivered. A non-disclosure agreement is available on request, which suits projects still under wraps or seeking funding.
| Tier | Delivery | Revisions |
|---|---|---|
| Basic | 7 days | 3 |
| Standard | 14 days | 6 |
| Premium | 25 days | 10 |
Basic covers a single chain with balance display and a transaction history view limited to the last 20 transactions. Standard adds support for up to 4 chains, a chain switcher, the swap interface and the NFT gallery, plus a custom Figma file. Premium extends this to unlimited chains, smart contract integration, a staking and yield interface, an admin panel, wallet analytics and 30 days of post-delivery support.
Share the chain and contract details to begin, and a live preview on your selected chain ships within 48 hours, with no payment required upfront.
Your order opens its own thread here the moment it is paid, and everything about that order - questions, changes and the final report - happens in it.
This package only covers the frontend. If Solidity contracts are required - for tokens, NFTs, staking, a presale or a DAO - that work is quoted separately, starting at $400, so just get in touch.
Yes, it works on mobile. WalletConnect v2 manages mobile wallet deep-links, and every screen is fully responsive down to 320px. It has been tested on iOS Safari, Android Chrome, and in-wallet browsers such as MetaMask Mobile and Trust.
Yes, it integrates with REST, GraphQL or webhook APIs. Share the documentation and it will be connected.
Deployment to Vercel is included as standard (the free tier suits most projects), and the live URL is handed over. Cloudflare, Railway or self-hosting can be set up instead if preferred.
Any changes within the original scope are free for 14 days after delivery. New features are quoted separately.
Yes, through a wallet-adapter. It is handled as a separate integration from EVM chains, though still fully supported. Adding it to a Basic order carries a minimum charge of $50.
Alchemy, Infura or QuickNode are used depending on the chains involved. If you already have RPC endpoints, send them over; otherwise free-tier keys are set up and swap instructions documented.
Yes - authentication can use SIWE, standing for Sign-In With Ethereum, or a custom signing message instead, suiting gated content, admin areas or user accounts. It's included in Premium, and offered as an add-on for Basic or Standard.
A testnet contract can be used first, with a swap to mainnet once deployed. Alternatively, mock ABIs can be used and replaced with the real ones at handoff.
The Standard tier comes with a Figma file for the finished interface, while Premium includes a full design system. Basic doesn't include Figma - the buyer supplies the design or signs off on the in-code layout.
Full intellectual property and source code belong to the buyer upon final delivery. Repository access, documentation, deployment credentials plus environment configuration all transfer together with final payment, leaving no licensing restrictions, ongoing fees or vendor lock-in.
Each delivery is checked for wallet connections across MetaMask, WalletConnect v2 and Coinbase Wallet, covering major desktop browsers and mobile in-wallet apps. Chain switching, wrong-network prompts, signature rejections and transaction failures are all tested manually beforehand, and testnet dry-runs can be requested.
Backend development covering secure REST APIs, database integration, authentication and testing, built with Express.js and MongoDB, delivered in 5 days for $25.99.
Custom Chrome extension built in JavaScript or TypeScript on Manifest V3, with tiers covering 1 to 5 screens, optional Firefox and Edge support, and source code delivered to your own repository.
We diagnose and repair Chrome extensions broken by Chrome updates, site markup changes, or the move to Manifest V3, working from your existing JavaScript or TypeScript codebase.
Custom Android and iOS apps built with Flutter or React Native, ranging from simple MVPs to full products with backend, admin dashboard and automated build pipeline, with a working preview before final payment.
We build custom Shopify apps, AI-powered chatbots, workflow automation and analytics tools that bring your scattered business systems into one place, drawing on more than 10 years of full-stack eCommerce engineering.
A custom-built, fully responsive website or web app delivered from scratch in 3 days, with clean source code ready to deploy.
