An extremely simple BIP write-up for a backward compatible URI scheme to help with segwit adoption by online stores and merchants. ==== This BIP is a modification of an earlier [[bip-0021.mediawiki|BIP 0021]] by Nils Schneider and Matt Corallo ==Abstract== This BIP proposes a URI scheme which allows for backward compatibility with native segwit (bech32) wallets and legcy wallets (base58) ==Motivation== The purpose of this URI scheme is to enable all users to easily make payments from any wallet, without allowing backward compatibility to be a barrier to segwit adoption. This BIP allows a merchant to preferentially receive payments to a bech32 address, while gracefully allowing older clients to make base58 encoded payments. ==Specification== === Query Keys === *addr: an alternative bitcoin destination which is preferred over the "bitcoinaddress" field of the url == Appendix == === Simpler syntax === bitcoin:
