Exchange Bitcoin (BTC) to Stellar (XLM)

A Stellar recipient may provide a normal account with a separate memo or a muxed address. Read that instruction before committing BTC to the exchange.

Two ways a receiver can identify a beneficiary

Receiver instructionInformation to preserveQuestion before funding
G-address with a separate memoThe address, memo value and required memo typeCan the offered payout represent this complete instruction?
M-addressThe complete muxed address supplied by the recipientIs this address format supported by the offered payout?
Instruction without a memo requirementThe receiverโ€™s actual account and current conditionsIs no memo really intended, rather than merely missing from a screenshot?
A copied label such as โ€œmy Stellarโ€No reliable payment instruction by itselfWhere are the current receiving details for that specific account?
G and M identify address-format families here; these labels are not usable payment addresses.

An embedded identifier is still part of the receiving instruction

Stellar documentation describes M-addresses as an encoding of an underlying G account together with an identifier. Not every wallet or platform supports muxed accounts. A format understood by the network is therefore not automatically a format supported by every exchange interface.

A separate memo also has a type. Stellar defines text and numeric ID memos, among other types. Keep the requested type and value together instead of deciding that two similar-looking displays are interchangeable. You do not need to learn transaction construction to use a deposit instruction, but you do need the sending form and receiving service to agree about the required information.

Ask a precise compatibility question

Identify what the receiver actually provided
Save the current instruction for the account to be credited. State whether it contains a separate memo or one complete M-address. If you only have a saved address-book name, reopen the receiver rather than guessing what that name represents.
Describe the mismatch instead of editing it away
If the payout form rejects the supplied format or leaves the memo type unclear, ask whether that exact receiving instruction is supported. Do not simply remove the muxed identifier, change its prefix or move an unexplained number into a different field.
Obtain alternative details from the receiver if needed
If a different format is required, the receiver must confirm an acceptable complete instruction. Do not construct a G-address-and-memo alternative from an M-address by hand as a workaround. Clarification should happen before the Bitcoin funding payment, not after it.

Questions about XLM receiving formats

Can I shorten an M-address to make a form accept it?
Do not remove information to force acceptance. Clarify supported formats and obtain any alternative complete instruction from the receiving service before funding.
Does the memo value alone define a complete instruction?
Retain the required memo type, value and address as one set. If the type is unclear in either interface, resolve that mismatch before making the exchange payment.
Can a Bitcoin transaction reference prove XLM account credit?
It identifies the funding leg, not the Stellar payout or the receiving platform balance. Keep the references separate and investigate the actual payout if credit is missing.
