Muxed accounts, a Stellar feature that maps a single address to multiple virtual accounts, are now live and available to all ecosystem products. All services must support sending to muxed accounts, while custodial services should implement them on the receive side to eliminate memo-related user errors.
Muxed accounts are now live on Stellar, enabling a single Stellar address to map to multiple virtual accounts via a 64-bit integer ID. These accounts start with M instead of G and are 69 characters long. Custodial services and exchanges use muxed accounts to route incoming payments without requiring users to manually enter memos, eliminating a major source of lost funds and support tickets. All Stellar products must support sending to muxed accounts to maintain ecosystem interoperability. Services using pooled account models should implement muxed accounts on the receive side to improve user experience. Traditional G addresses and memos continue to work, but adopting muxed accounts is increasingly important for ecosystem compatibility.
