Base58 is used to represent [[bitcoin]] addresses.<ref>{{cite web |title=Protocol documentation |url=https://en.bitcoin.it/wiki/Protocol_documentation#Addresses |website=Bitcoin Wiki |access-date=10 July 2021}}</ref> Some messaging and social media systems [[Line wrap and word wrap|break lines]] on non-alphanumeric strings. This is avoided by not using [[Percent-encoding#Types of URI characters|URI reserved characters]] such as +. For [[SegWit]], it was replaced by Bech32, see below.
