Sei is a Layer 1 blockchain dedicated to specialized areas for transactions, optimizing and benefiting exchanges within the network to provide the best user experience.

Moreover, the project has announced that it will reserve 1% of the tokens for users who join and experience the Sei network testnet. Currently, Coin98 Wallet supports creating and importing Sei testnet wallets to interact with this network, under the condition that you have a Sei wallet. This article will provide a detailed guide on how to create a Sei wallet.

What is Sei Wallet?

A Sei wallet is where SEI tokens are stored on the Sei blockchain. You can send and receive SEI, as well as participate in the testnet version of this blockchain. The wallet is owned by its user and no other party has access to it.

What does a Sei wallet include?

A Sei wallet has 3 crucial information you must note down:

  • Wallet address: A sequence of numbers and characters used to send & receive assets to the Sei wallet. Users can transfer coins to each other through the wallet address. Example of a Sei wallet address: sei1pweq2c9z0496w9rhwz3qknt87s72jhz3qvdh87
  • Passphrase: A security key, or a type of password consisting of 12 random English keywords. You must have the wallets’ Passphrases to restore them. Example of a Passphrase: very siren gauge original burger toast wheel simple reason crash often vessel.
  • Private Key: Private Key is a string of letters and numbers, similar to a bank account’s password. Example of a Private Key: 2b4ced1c0ed189c2a4bcc8015018efda1d44096a208e4c2a7e01b45e02882a65

After creating a wallet, you will receive its wallet address, passphrase and private key similar to the examples above.

To visualize, you can imagine that the Sei wallet is a bank account, the wallet address is the account number and the passphrase is the password.

The difference here is that with a bank account, other people will know your personal information. As for the Sei wallet, users become anonymous, no one knows who owns the wallet, and transactions only occur through the address encoded into a sequence of numbers and characters.
