The problem

The ecosystem needed a branded marketplace for its NFTs with smooth wallet onboarding, and the team wanted to evaluate two Web3 SDKs on identical UX before committing.

What I built

  • Built the Sequence version with embedded wallet integration, gasless transactions, minting, and trading.
  • Built the thirdweb version as a wallet-connected explorer that lists the collection's NFTs from Ethereum, with trading planned as the next phase.
  • Designed both on the same Next.js component library so the SDKs could be compared fairly.
  • Handled collection data from OpenSea and Etherscan sources so listings stay consistent across marketplaces.
