The XRP Ledger protocol requires that each XRP Ledger wallet holds a small amount of XRP at all times. This is called a reserve and its purpose is spam protection (more details about XRP reserve are available here).
The main reserve requirements are:
- 1 XRP per XRP Ledger wallet (always required - cannot be withdrawn)
- 0,2 XRP per each trust line (until disabled)
Trust lines can be disabled in order to make additional XRP available. How to disable a trust line?
- 0,2 XRP per each open order (until executed or cancelled)
Example:
- A wallet has an XRP balance of 10 XRP
- It has ETH and EUR trust lines enabled
- It has one open order
Available balance is:
10 XRP - 1 XRP (base reserve) - 2 x 0,2 XRP (trust line reserve) - 0,2 XRP (open order) = 8,4 XRP
XRP Ledger wallet balances cannot be consolidated. Each active XRP Ledger wallet must hold at least 1 XRP. Completely deleting an XRP Ledger wallet is possible with the Deletable Account Amendment from May 8, 2020. GateHub will support this option soon. More information is available here.
Deleting an XRP Ledger wallet from your GateHub account will not make the 1 XRP reserve available.
