Installing seid CLI

Complete guide to installing and setting up the Sei CLI (seid) tool, including wallet creation, EVM imports, and troubleshooting common installation issues.

What is seid CLI?

The seid CLI is the command-line tool for interacting with the Sei blockchain. It allows you to manage wallets, send transactions, query network data, and perform validator operations.

Prerequisites

• Go 1.23+: Installation instructions are available here.

Installation

To install seid, locate the version you wish to use on the sei-chain releases page. A list of the currently used versions on mainnet and testnet are displayed right below.

Then, execute the following commands with the version that you picked:

git clone https://github.com/sei-protocol/sei-chain
cd sei-chain
git checkout [VERSION]
make install

You can verify that seid was installed correctly by running:

seid version

Troubleshooting Installation

If you encounter an error like command not found: seid, you may need to set your GOPATH environment variable.

• Use go env GOPATH to find your GOPATH
• Add the following lines to your ~/.bashrc or ~/.zshrc:

export GOPATH=[your GOPATH from step 1]
export PATH=$PATH:$GOPATH/bin

For more information see here.

Adding a Wallet

You can create a new wallet using the seid keys command:

seid keys add $NAME

Output:

- name: [YOUR_KEY_NAME]
  type: local
  address: sei1[GENERATED_ADDRESS]
  evm_address: ""
  pubkey: '{"@type":"/cosmos.crypto.secp256k1.PubKey","key":"[PUBLIC_KEY]"}'
  mnemonic: ""

**Important** write this mnemonic phrase in a safe place.
It is the only way to recover your account if you ever forget your password.

[YOUR_24_WORD_MNEMONIC_PHRASE]

Please replace $NAME with the name you would like to use for this key. This will generate a seed phrase and store the account in the CLI for use.

Important: Write this mnemonic down and store it in a safe place. Never share your seed phrase with anyone.

Alternatively, if you would like to import an existing seed phrase, you can add the --recover flag:

seid keys add $NAME --recover

Output:

This will prompt you to enter your seed phrase, allowing you to import an existing wallet into the CLI.

> Enter your bip39 mnemonic
[ENTER_YOUR_EXISTING_MNEMONIC_PHRASE_HERE]

- name: [YOUR_WALLET_NAME]
  type: local
  address: sei1[RECOVERED_ADDRESS]
  evm_address: ""
  pubkey: '{"@type":"/cosmos.crypto.secp256k1.PubKey","key":"[PUBLIC_KEY]"}'
  mnemonic: ""

EVM Wallet Compatibility

Understanding Coin Types

Sei supports two coin types:

• Coin type 118 (default): Standard Cosmos address format
• Coin type 60: Ethereum-compatible address format for EVM wallets

Creating an EVM-Compatible Wallet

To create a new wallet that’s compatible with EVM wallets like MetaMask:

seid keys add $NAME --coin-type=60

Output:

- name: [YOUR_KEY_NAME]
  type: local
  address: sei1[GENERATED_ADDRESS]
  evm_address: ""
  pubkey: '{"@type":"/cosmos.crypto.secp256k1.PubKey","key":"[PUBLIC_KEY]"}'
  mnemonic: ""

**Important** write this mnemonic phrase in a safe place.
It is the only way to recover your account if you ever forget your password.

[YOUR_24_WORD_MNEMONIC_PHRASE]

evm_address is shown as empty here because it’s only displayed after the key first broadcasts a transaction or is associated on-chain. The 0x address is deterministically derived from the secp256k1 public key.

Importing an Existing EVM Wallet

To import an existing wallet from MetaMask or other EVM wallets:

seid keys add $NAME --coin-type=60 --recover

Output:

> Enter your bip39 mnemonic
> [ENTER_YOUR_EXISTING_MNEMONIC_PHRASE_HERE]

- name: [YOUR_WALLET_NAME]
  type: local
  address: sei1[RECOVERED_ADDRESS]
  evm_address: ""
  pubkey: '{"@type":"/cosmos.crypto.secp256k1.PubKey","key":"[PUBLIC_KEY]"}'
  mnemonic: ""

You’ll be prompted to enter your existing 12 or 24-word mnemonic phrase.

Use coin type 60 when you want to use the same address across EVM-compatible chains or import from MetaMask. Use the default coin type 118 for standard Cosmos operations.

Managing Wallets

To see your local wallets, you can run:

seid keys list

Output:

- name: [YOUR_WALLET_NAME]
  type: local
  address: sei1[WALLET_ADDRESS]
  evm_address: [EVM_ADDRESS]
  pubkey: '{"@type":"/cosmos.crypto.secp256k1.PubKey","key":"[PUBLIC_KEY]"}'
  mnemonic: ""
  ...

to see a list of all wallets added, or

seid keys show $NAME

Output:

- name: [YOUR_WALLET_NAME]
  type: local
  address: sei1[WALLET_ADDRESS]
  evm_address: [EVM_ADDRESS]
  pubkey: '{"@type":"/cosmos.crypto.secp256k1.PubKey","key":"[PUBLIC_KEY]"}'
  mnemonic: ""

to see details about a specific wallet.

Deleting Wallets

To delete a wallet/key, you can use the following command:

seid keys delete $NAME

Output:

Key reference will be deleted. Continue? [y/N]: y
Key deleted forever (uh oh!)

This will remove the specified wallet from your local keyring. Be cautious, as this action cannot be undone.

Uninstalling seid

If you need to remove seid from your system, you can delete the binary from your $GOPATH/bin directory:

rm $(go env GOPATH)/bin/seid
