Start here

D17 has two user-facing surfaces:

• the participant terminal, which displays launches and lets a connected wallet call launch and locker actions; and
• the deploy page, which builds one immutable createLaunch transaction and asks the wallet to sign it.

It also has two interchangeable read arrangements:

• direct RPC, where the browser reads the chain itself; and
• optional API, where a small self-hosted indexer reads any compatible Ethereum RPC and serves snapshots plus realtime notifications.

Neither arrangement moves funds. Reads come from public chain data; writes are wallet-signed contract calls.

Recommended first run

Use Sepolia, direct RPC mode, and a throwaway test wallet. Read the five-minute start, open one existing launch, inspect its rules, and only then test a small commit/refund lifecycle.
