Project details

Looking to integrate Web3 (smart contracts/ wallets) on React/Next frontend or HTML/CSS/ JavaScript? Guess, you've come to the right place.

Hello there, I'm Hammad, a full-stack blockchain developer and I have been working on web3 applications for a long time. In my journey, I've done integration of different web3 (decentralized) applications including DeFi, NFT, Interoperability (bridges), ICO, Staking, & E-commerce

Catalog's offering:

 • Web3 JS/Ethers JS integration on your frontend to enable communication with the smart contract.
 • Wallet connections (MetaMask, WalletConnect, Coinbase, etc)

Here's what I need from you before working on your project:

 • A frontend built using React/ Next framework or in HTML/ CSS/ JavaScript.
 • A smart contract that is written in Solidity (any EVM-compatible chain).

I can also build a frontend for your dApp or a custom smart contract or subgraph but these services ARE NOT covered in this catalog. Check out my other catalogs if you want these services or message me so we can discuss.

Please message me before ordering as I'd love to discuss the project with you in advance because the delivery time and cost vary from project to project.

Smart Contract Audit Hammad's knowledge and understanding of smart contract mechanics were highly impressive. He was able to complete the necessary tasks and even offer suggestions that created an even better outcome than I had planned for with my own designs. He was confident enough to take tings to a new level and care for the project as if it was his own. A great experience!
