Address Types

Understanding G, M, and C addresses.

Stellar uses different address formats for different purposes. This library ensures you handle them correctly and safely.

Support Table

Type	Prefix	Description	Usage
G Address	G...	Ed25519 Public Key (Classic)	Primary account identifier.
M Address	M...	Multiplexed Address (SEP-23)	G-address + 64-bit Memo ID.
C Address	C...	Contract ID (Soroban)	Identifier for smart contracts.

M-Addresses (Muxed)

Multiplexed addresses are the preferred way to handle deposits for pooled accounts. They encode both the destination and the user’s ID into a single string, removing the need for a separate memo field.

The library automatically expands M-addresses into their base G-address and routing ID.

C-Addresses (Contracts)

C-addresses are NOT valid for classic deposit routing. Contracts do not have a “memo” field in the same way accounts do.

If a user provides a C-address in a classic deposit flow, the library returns an INVALID_DESTINATION error. Contracts should only be used as destinations for Soroban-specific integrations.
