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.

Outcome

Both builds shipped, so the team could compare Sequence and thirdweb on identical UX before committing to one.
