Installing seid CLI

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+ (build from source only): Installation instructions are available here. The prebuilt binary has no prerequisites.

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.

Prebuilt binary (recommended)
Build from source

Each release attaches a statically linked seid build for linux/amd64 with no runtime dependencies:

VERSION=<version-tag>  # e.g. v6.6.1 — see the version table above
FILE=sei-chain_${VERSION#v}_linux_x86_64.tar.gz  # asset filenames omit the leading v

curl -fLO https://github.com/sei-protocol/sei-chain/releases/download/${VERSION}/${FILE}
curl -fLO https://github.com/sei-protocol/sei-chain/releases/download/${VERSION}/checksums.txt

# Verify integrity before trusting the binary; extract and install only if it passes
sha256sum -c checksums.txt --ignore-missing \
  && tar -xzf ${FILE} seid \
  && sudo install -m 0755 seid /usr/local/bin/seid

Prebuilt binaries are attached from v6.6.1 onward — for earlier versions, build from source. They are linux/amd64 only and omit hardware Ledger support. On other architectures, or if you sign with a Ledger device, build from source.

Previously installed with make install? An older copy in $(go env GOPATH)/bin can shadow /usr/local/bin/seid depending on your PATH order — which -a seid lists every copy.

git clone https://github.com/sei-protocol/sei-chain
cd sei-chain
git checkout <version-tag>
make install

You can verify that seid was installed correctly by running:

seid version

Troubleshooting Installation

If you built from source and 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

Use "seid [command] --help" for more information about a command.

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, delete the binary from wherever it was installed:

# Prebuilt binary install
sudo rm /usr/local/bin/seid

# Build-from-source install
rm $(go env GOPATH)/bin/seid
