Built with SolRengine
Real Solana dApps built in Rails — each with a live demo or screenshots, full source, and a case study of how it works.
Starter — the create-solana-dapp for Rails
The Rails 8 Solana starter every SolRengine dApp is scaffolded from — wallet auth, token portfolio, SOL transfers, and 20+ UI components, ready to clone and ship.
Lamport — a neobank on Solana, in Rails
A custodial neobank where users sign up with an email and get a Solana wallet they never have to manage — per-user custody, P2P transfers with on-chain proof, and live balances, built in Rails 8 on the Solana Developer Platform.
Kudos — a loyalty points program on Solana
A rewards app where users sign up with an email, get a custodial Solana wallet, and earn/redeem points minted and burned on-chain — the SolRengine issuance reference app.
WalletTrain — a full Solana wallet in Rails
A complete Solana wallet — SIWS sign-in, token portfolio with USD prices, SOL transfers, and real-time balance updates over WebSocket — built in Rails 8 with SolRengine.
Mercado — a Solana storefront with on-chain receipts
A digital-goods storefront that takes SOL payments and mints an on-chain receipt PDA for every order — built end to end in Rails 8 with SolRengine.
Voting — on-chain voting where Solana is the database
A community voting dApp where every vote lives on-chain and Rails stores no votes at all. Polls, candidates, and tallies are PDA accounts read straight from Solana.
PiggyBank — time-locked SOL savings on-chain
Lock SOL until a future date with a custom Anchor program, driven entirely from Rails — IDL parsing, Borsh encoding, and on-chain account queries with SolRengine.
Solana Bytes — a hex visualizer and arcade game
Paste any Solana address and see its raw account bytes color-coded by field — then turn it into an 8-bit arcade game. A Rails app that decodes on-chain data in Ruby.
