A staking app and wallet sign-in API for a BNB Smart Chain token, built in 12 weeks

A token project on BNB Smart Chain needed an app around its staking pools. We built the landing site, the staking app and an API that signs users in with their wallet or email.

The challenge

Holders needed one place to lock tokens in pools with set terms, see their position and claim.

Sign-in had to work for wallet users and for people who prefer email.

Our approach

Wallet-first sign-in

Users sign in by signing a one-time message with their wallet, or with an email code, and get a session token.

One app for every pool

The staking app reads each lock pool from the contract and shows its terms, caps and the holder's position.

Shipped in containers

Docker images and GitHub Actions deploy the app and the API the same way every time.

What we built

A landing site for the token.
A staking app with lock pools, claims and unstaking.
An auth API with wallet signatures, email one-time codes and sessions.
Docker builds and GitHub Actions deploys.
