Planning aid / Sheet 01
Configure a Bitcoin app before you build it.
Choose how the app handles keys, where its chain data comes from, and which supporting modules it includes. Each choice redraws the schematic and rewrites the plan summary beside it.
Nothing is saved, sent, or looked up. Reloading the page returns the default plan. On small screens the schematic and summary sit below the options.
Default plan loaded. Change any option to update the schematic and summary.
Reading the schematic
Filled boxes are active in the plan. Dashed boxes are options you have not chosen. The central block is the app core, which every plan includes.
Lines show the flow. Key options feed the core from the left, chain data options feed it from the right, and modules sit beneath it.
What this planner does not do
It does not estimate costs, recommend a provider, check any live network, or judge whether a particular app is safe. For that, use the review checklist and an independent reviewer. This is a planning aid, not financial, legal, security, or medical advice.
