#### Read Only Applications

Dashboards, explorers etc

1. Connect to Midgard to get rich data about the system, included time-series graphs and aggregated values like TotalVolume etc. 
2. Connect to SwipeNode (or proxied via Midgard) to drill into the state-machine and access the current state (or historical just by adding a `?height=1234` to specify a certain height. 
3. Connect to RPC to get information about the Ledger, which is not specific to SwipeChain, such as `/genesis` or account/transaction information

#### Write Applications

Wallets, interfaces etc.

These applications require first-principle thinking and excellent understanding of how the system works.

1. Connect to a trusted SwipeNode or connect to several public SwipeNodes and ensure they all agree
2. Get the `/inbound_addresses`
3. Compose the transaction with the correct memo and correct gas price. 
4. Send the vault the transaction and wait for execution

**Connecting**

First, you need to connect to SwipeChain. You can use the official clients which have SSL, or run your own node, host it on SSL.

{% hint style="info" %}
If you don't need SSL, you can connect to any of the non-SSL public nodes (ie, just their IP address). Web applications need SSL, but mobile and desktop apps don't.
{% endhint %}
