Hey,
I'm building AltForge — a multi-chain crypto platform where users can deploy ERC-20 tokens, swap assets, track transactions, and manage their portfolio, all from one dashboard. I'm looking for an experienced Web3 developer to take an already-built, working prototype to a fully launchable product.
What's already done:
The prototype is complete — frontend and backend both built. Here's what exists:
Full UI — landing page, dashboard, send/receive modals with QR codes, swap interface, gas tracker, TX tracker, session manager, portfolio page, settings
Real MetaMask wallet connect via ethers.js
Node.js + Express backend with JWT authentication, SQLite database, real Etherscan API integration for live gas prices and TX lookups
Session management — tracks active devices with location, revoke support
Two-tier plan system — Free (1% fee) and Pro (0.4% fee)
Deployment configs for Railway/Render already written
Supported chains: Ethereum, BSC, Polygon, Fantom, Moonriver
What I need from you:
Must have for launch:
Real wallet balance fetching via Alchemy/Infura — read actual ETH + ERC-20 balances from connected wallet and display in portfolio
Real swap execution — the swap UI is fully built, needs 1inch or 0x Protocol API wired in to execute actual on-chain swaps via ethers.js
ERC-20 token factory smart contract — so users can create tokens from the dashboard (name, symbol, supply, decimals)
On-chain fee collection — platform takes 1% / 0.4% cut on swaps, needs smart contract routing to collect it
For launch readiness:
Proper invite/access code system — replace hardcoded codes with a real invite management flow
Pro plan payment — Stripe or crypto payment gateway for upgrades
Security review of auth, API endpoints, and contracts before going public
Tech stack:
Frontend: Vanilla HTML/CSS/JS (intentional, no framework)
Web3: ethers.js 6.x
Backend: Node.js + Express, SQLite, JWT
Blockchain data: Etherscan API family
Smart contracts: Solidity (your area)
Hosting: Railway or Render
What I'll give you:
Full source code immediately
Walkthrough call to explain everything
Quick responses and clear feedback throughout
Test wallet and API keys for development
What I'm looking for from you:
A couple of relevant Web3 projects you've shipped
Rough timeline for the core items above
Your rate (hourly or fixed, both fine)
Happy to jump on a call anytime to show you the prototype live. Looking forward to it.
