Solana Wallet Q&A

Basic concept

SOL: Solana’s native token, which you can obtain from the exchange

Transfer failed

Any transaction on the Solana chain will cost a certain amount of SOL as a handling fee. Please make sure you have a certain amount of SOL in your wallet.

Solana Sub-address

Each Token in the Solana wallet has a separate sub-address. For example, the sub-address of SOL, MATH, and USDC are different on the chain, and each sub-address needs to be activated.

SPL Token transfer

Currently there are two ways to transfer and receive SPL tokens:

Why could a transaction in the browser explorer have multiple transaction records?

When transfer MATH, for example, because SPL has a sub-address system, so:

Why we can not receive the deposit in the account?

Due to the SPL transfer system issue, please pay attention to the following points:

  • Deposit into exchange, please make sure whether the exchange supports SPL sub-address system. Currently, only FTX exchange supports SPL sub-address. Before depositing into any centralized exchange or any other platform, please make sure whether the other platform supports SPL sub-address. There are many users who deposit USDC and other assets into the SOL receiving address of the exchange, causing losses (small test is recommended first).
  • If user deposit token into exchange and it shows partially deposited into the account, it is because there are multiple transaction records, the exchange only supports the deposit of single transaction, and does not support displaying the total amount of B1… B*.

About the cross-chain

Ethereum cross-chain to Solana. Due to the sub-address system, if you need to make a cross-chain transfer of ERC20 asset to Solana chain, make sure there is a corresponding SPL Token sub-address under the SPL address, otherwise it will not be able to make the cross-chain transfer.

Wallet import path

Different Solana wallets will have different mnemonic paths, which will change the SOL address when export the mnemonic phrases from other wallets (such as Sollet) into MathWallet.
