CRUMB.RUN is an on-chain pulse board built for Cookie Chain. Connect a Solana-compatible wallet (Nightly recommended), choose a signal, and publish it as a permanent Memo Program transaction. The interface tracks confirmation in real time and reconstructs the connected wallet's signal trail from chain history.
- Nightly support through the Solana Wallet Standard
- Cookie Chain RPC connection
- Four on-chain signals:
BUILD,SHIP,HODL,CHAOS - Live transaction lifecycle and actionable errors
- CookieScan transaction links
- Wallet balance and on-chain signal history
- Responsive terminal-inspired interface
Every signal invokes the canonical SPL Memo Program with:
CRUMB.RUN:v1:<SIGNAL>:<UNIX_TIMESTAMP_MS>
Program address: MemoSq4gqABAXKb96qnH8TysNcWxMyWCqXgDLGmfcHr
Only the normal Cookie Chain fee is paid. CRUMB.RUN does not transfer or custody funds.
Requires Node.js 20+ and Nightly configured for Cookie Chain.

- Confirm the connected wallet address is visible.
- Publish a signal and approve it in Nightly.
- Wait for

- No private keys or seed phrases are requested or stored.
- Transactions require explicit wallet signatures.
- Each action submits one Memo Program instruction.
- Use a low-value development wallet and verify instructions before signing.
Source implementation does not by itself prove a production deployment or real Cookie Chain transaction. Those require separate verification.
