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 sign in 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.
