What do I do if I transferred XRP to Tangem Wallet, but the amount of XRP I received was 1 less than expected? What if I transferred XLM to Tangem Wallet, but received 1 less XLM than I should have?

The XRPL and Stellar blockchains use the concept of accounts. To open an account on XRPL you need to deposit at least 1 XRP, while the minimum on Stellar is 1 XLM. When you open an account, these funds are reserved and remain unavailable for withdrawal. For example, if you deposit 10 XRP, 1 XRP will be reserved for creating an account, and the balance will show 9 XRP available to spend.
