When using a payment service, you are trusting the service provider to store your deposit and to withdraw your funds. This idea of trust is implemented on Stellar through trustlines.

You add trustlines to your Stellar account to hold a token, buy and sell it. Trustlines also prevents receiving unwanted assets. For example, you wouldn’t want to receive counterfeit dollars from a person or service you don’t trust.

In order to send, receive, or hold any asset on the Stellar network you must first establish a trustline with the account issued the asset. An issuing account is a Stellar account that created the asset.

Trustlines are set through blockchain transaction that requires a fee of 0.5 XLM (which is the main stellar crypto asset) each. So,  for each trustline you set, your account will be required to maintain 0.5 XLM in reserve that can’t be spent until you close your trustlines.

Most wallets make adding trustlines as easy as a few clicks. Watch the video from our community member Kirill and learn how to do this in your Interstellar wallet.
