Wallets and on-chain features in a normal web product
Your users shouldn't need to understand blockchains to use your product. We add wallet login, payments and on-chain data to web apps and WordPress sites, and everything around them looks and works the way your users already expect. No jargon required.
Who it's for
- 01
You want visitors to sign in or pay with a crypto wallet like MetaMask.
- 02
Your product needs to show on-chain data, like balances or ownership, right next to regular content and in the same design.
- 03
You run WordPress and don't want a rebuild.
- 04
You already have a smart contract and need it connected to your site or app.
What we do
- 01
Wallet
Connect wallets such as MetaMask, in the Chrome extension or on a phone, for login and payments.
- 02
Your product
Show on-chain data in your pages and admin panel.
- 03
Contract and chain
Connect your product to existing smart contracts on Ethereum and other EVM networks, and write straightforward contracts in Solidity when you need one. If a contract will hold real money, we recommend an independent audit before launch.

How we use AI
At Codality our developers use AI coding assistants like Claude Code for routine code and tests, so less of your budget goes on boilerplate. A developer reviews and tests every change, and answers for what ships. Rather keep your code away from AI? Say so, and we'll work without it.
We charge $40 an hour. For a new product, the MVP calculator gives you a price range and a timeline in about 1 minute. Fixed price works too.
Estimate your MVPQuestions founders ask us
Didn't find yours?
Yes. We built a MetaMask plugin for WordPress in 2023 that does exactly that. We can add the same to a custom web app.
Ethereum and EVM-compatible networks: Polygon, Base, Arbitrum and BNB Chain. On the front end we connect MetaMask and other wallets through WalletConnect.
Yes, if it's a straightforward one. Will it hold real money? Then we'd also have an independent auditor check it before launch. It's cheaper than finding a bug after.
