Your wallet address is the unique identity of your wallet that's used to send and receive cryptocurrency. Each currency has its own logic, but generally they look something like this: 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa (that's the world's first Bitcoin address, if you were wondering).
In the crypto industry, there are several different formats of wallets. Some are unique to a specific coin and some formats were designed for adaption to multiple different kinds of currencies. Here are the most common types and which ones we accept:
Wallets that begin with a “1”
This is the original format of wallet, also known as Legacy or (P2PKH) wallet, and is incompatible with SegWit improvements.
Wallets that begin with a “3”
Nested SegWit, or P2SH addresses, are a newer form of wallet type that essentially removes some signature data from transactions, lowering the size of the transaction data needed to store in one block, therefore freeing up more space for additional transactions to be added to the same block. This means the network can process more transactions per block and the sender pays lower transaction fees.
Wallets that begin with a “bc1”
Native SegWit, or bech32 addresses, differ from Nested SegWit wallets in that many exchanges and crypto providers aren’t yet compatible with these formats, Coinmama included. If you do not know how to generate or find a different address from within your wallet, contact our support team here or check your wallet provider's support center. That being said, note that SegWit addresses are backward compatible, meaning that you can send funds from a Bitcoin SegWit address to a Legacy Bitcoin address.
Wallets that begin with a “0x”
These are Ethereum wallets. If your order status in your Coinmama account has been completed and you still don't see the coins in your wallet, it's possible that your wallet provider doesn't accept smart contracts. If this is the case, you need to contact them directly to learn what happened to your coins (they may ask you for the transaction hash, and you can find that by clicking the wallet link in your Coinmama account’s transaction history, or by asking one of our Happiness Heroes).

Wallets that begin with an “r”
These are Ripple addresses, and if you send coins to a Ripple wallet, make sure to double-check that the destination tag is correct. By creating a Ripple wallet, you’re essentially creating an account that contains your transactional history and registers you as a Ripple transactor. Private exchanges usually hold all their customers' XRP in a few shared XRP Ledger accounts, so customers don't have to pay the reserve for individual accounts on the exchange. Note that funding a Ripple account does not give you access or special privileges over that account - only the private key holder has access, just like with other crypto wallets.

Wallets that begin with a capital “X”
To send Ripple from your wallet to someone else’s XRP wallet, you’ll most likely need their address as well as a destination tag. Ripple addresses that begin with a capital X are a new format that was introduced in 2019, and serves as a combined wallet address and destination tag; this new format will help prevent users from entering the wrong tag or from skipping that crucial step.
Coinmama does not accept this format of Ripple wallet. For more information on Ripple wallets and destination tags, click here.
Wallets that begin with “q” or "bitcoincash:"
These are newer formats of Bitcoin Cash wallets, mainly for the purpose of distinguishing between BCH and BTC wallet addresses, which both may begin with “1” or “3”. Accidentally sent your BCH to a BTC wallet? Click here for more information on the subject.
