Web3 Wallet Integration Needed

I have a fully-functional online shop preparing for the 2026 New Year rush, and I now want customers to interact with it through their crypto wallets. The site is ready; what’s missing is the Web3 layer.

Here’s what I need you to handle:

• Seamlessly wire MetaMask, Coinbase Wallet and Trust Wallet to the store, all on the Ethereum network. • Allow shoppers to pay for products directly from their wallet, have the option to with that same wallet instead of e-mail/password, and automatically accrue on-chain loyalty rewards after each confirmed purchase. • Supply or adapt the necessary smart contracts, then connect them to the existing front-end. • Deliver clear, step-by-step deployment instructions so my team can move from testnet to mainnet without surprises.

The storefront, product catalogue and traditional checkout already work; your focus is purely the Web3 functionality. If you’ve rolled out similar integrations before and can move quickly, let’s talk and get this live well before the holiday traffic hits.

Budget: USD 2500 (Fixed Price)
