Check the leak before you send.
Shielding, deshielding and migrating from Orchard to Ironwood all put an exact amount on the public chain. Pre-flight measures how many recent transactions that amount would hide among, flags reused addresses, and plans the ZIP 318 alternative: standard denominations, broadcast at random intervals.
Runs entirely in your browser. The page downloads the same public history for everyone, then judges your plan locally. Amounts and addresses you type are never sent anywhere.
Before you broadcast.
Describe a transfer that crosses a pool boundary. Pre-flight tells you what will be public, how many recent transactions it would hide among, and how to do the same thing without the leak: a ZIP-318 split into standard amounts, spread over time.
