🎛️ seictl

Sei node operators' best friend

A command-line utility for managing Sei blockchain daemon. seictl provides tools to patch and modify Sei node configuration files (TOML) and genesis files (JSON) with ease. More features to be added in due course.

Features

• Configuration Management: Patch Sei daemon configuration files (app.toml, client.toml, config.toml)
• Genesis Management: Apply merge patches to genesis JSON files
• Universal Patching: Apply merge patches to any TOML or JSON file
• Smart Target Detection: Automatically detects which configuration file to modify based on patch content
• Flexible Output: Write to stdout, a specific file, or modify files in-place
• Atomic Writes: Safe file modifications using atomic write operations
• Merge Patch Algorithm: Intelligently merges patches with existing configurations

Build from Source

If you prefer to build from source or need a specific configuration:

Prerequisites

• Go 1.25.4 or higher

cd seictl
go build -o seictl

Install via Go

go install github.com/sei-protocol/seictl@latest

Usage

seictl [global options] command [command options] [arguments...]

Global Options

• --home <path>: Sei home directory (default: ~/.sei, can be set via SEI_HOME environment variable)

Commands

Patch Command

patch

Apply a merge-patch to any TOML or JSON file. This is a universal patching command that works with any file format, not just Sei-specific configurations.

seictl patch --target <file-path> [patch-file]

Options:

• --target <path>: Path to the TOML or JSON file to patch (required)
• -o, --output <path>: Write output to specified file
• -i, --in-place-rewrite: Modify the target file in-place

Examples:

# Patch any TOML file
seictl patch --target /path/to/config.toml patch.toml

# Patch any JSON file from stdin
echo '{"new_key": "value"}' | seictl patch --target /path/to/data.json

# Patch and save to a new file
seictl patch --target myconfig.toml patch.toml -o modified.toml

# Patch and modify in-place
seictl patch --target settings.json patch.json -i

Note: The file extension (.toml or .json) is used to determine the format automatically.

Genesis Commands

genesis patch

Apply a merge-patch to the Sei genesis JSON file.

seictl genesis patch [patch-file]

Options:

• -o, --output <path>: Write output to specified file
• -i, --in-place-rewrite: Modify the genesis file in-place

Examples:

# Patch from file and output to stdout
seictl genesis patch patch.json

# Patch from stdin
echo '{"chain_id": "sei-testnet"}' | seictl genesis patch

# Patch and save to a new file
seictl genesis patch patch.json -o genesis-modified.json

# Patch and modify the original file in-place
seictl genesis patch patch.json -i

Config Commands

config patch

Apply a merge-patch to a Sei configuration TOML file.

seictl config [--target <app|client|config>] patch [patch-file]

Options:

• --target <type>: Specify which configuration file to patch (app, client, or config)
  • If not specified, the target is automatically detected based on the patch content
• -o, --output <path>: Write output to specified file
• -i, --in-place-rewrite: Modify the configuration file in-place

Examples:

# Patch with auto-detection
seictl config patch patch.toml

# Explicitly specify the target config
seictl config --target app patch patch.toml

# Patch from stdin and output to stdout
echo 'minimum-gas-prices = "0.01usei"' | seictl config patch

# Patch and modify in-place
seictl config --target app patch patch.toml -i

# Patch and save to specific location
seictl config patch patch.toml -o /path/to/output.toml

Configuration Targets

The config command can work with three different configuration files:

app.toml

Application-level configuration including:

• Gas prices and block settings
• State management (state-sync, state-commit, state-store)
• EVM configuration
• Telemetry and monitoring
• API, gRPC, and Rosetta endpoints
• IAVL and WASM settings

client.toml

Client-level configuration including:

• Chain ID
• Keyring backend
• Output format
• Node endpoint
• Broadcast mode

config.toml

Node-level configuration including:

• Proxy app and database settings
• Logging configuration
• RPC and P2P settings
• Mempool and consensus parameters
• State sync and block sync
• Transaction indexing

Merge Patch Behavior

The merge patch algorithm works as follows:

1. Nested merging: Patches are merged recursively into nested structures
2. Null deletion: Setting a value to null removes that key from the configuration
3. Addition: New keys in the patch are added to the configuration
4. Replacement: Existing scalar values are replaced with patch values

Example:

Original:

[api]
enable = true
address = "tcp://0.0.0.0:1317"

Patch:

[api]
address = "tcp://0.0.0.0:1318"
swagger = true

Result:

[api]
enable = true
address = "tcp://0.0.0.0:1318"
swagger = true

Examples

Update Minimum Gas Prices

echo 'minimum-gas-prices = "0.02usei"' | seictl config patch -i

Enable API Endpoint

cat > patch.toml << EOF
[api]
enable = true
address = "tcp://0.0.0.0:1317"
EOF

seictl config --target app patch patch.toml -i

Modify Genesis Chain ID

echo '{"chain_id": "sei-mainnet-1"}' | seictl genesis patch -i

Update Multiple Configuration Sections

cat > patch.toml << EOF
minimum-gas-prices = "0.01usei"

[telemetry]
enabled = true
prometheus-retention-time = 60

[api]
enable = true
swagger = true
EOF

seictl config patch patch.toml -i

Patch a Custom TOML Configuration

# Patch any TOML file outside the Sei directory structure
cat > custom-patch.toml << EOF
[database]
host = "localhost"
port = 5432
EOF

seictl patch --target /etc/myapp/config.toml custom-patch.toml -i

Patch a Custom JSON Data File

# Modify any JSON file
echo '{"version": "2.0", "debug": true}' | seictl patch --target /path/to/settings.json -i

Using Custom Sei Home Directory

# Via environment variable
export SEI_HOME=/custom/path/.sei
seictl config patch patch.toml

# Via flag
seictl --home /custom/path/.sei config patch patch.toml

Command Comparison

When to Use Each Command

• patch: Use for patching any arbitrary TOML or JSON file on your system. Requires explicit --target path.
• genesis patch: Use specifically for Sei genesis files. Automatically uses $HOME/.sei/config/genesis.json.
• config patch: Use specifically for Sei configuration files with automatic target detection. Automatically uses files in $HOME/.sei/config/.

File Locations

By default, seictl looks for configuration files in the following locations:

• Genesis: $HOME/.sei/config/genesis.json
• App config: $HOME/.sei/config/app.toml
• Client config: $HOME/.sei/config/client.toml
• Node config: $HOME/.sei/config/config.toml

Where $HOME is the value of the --home flag or the SEI_HOME environment variable.

Safety Features

• Atomic Writes: All file modifications use atomic write operations (write to temp file, then rename)
• Permission Preservation: In-place modifications preserve original file permissions
• Format Validation: Validates file extensions before processing (must be .toml or .json)
• Target Validation: Prevents accidental modification of wrong configuration files
• Auto-detection Safety: Refuses to proceed if patch could apply to multiple targets
• Early Validation: Checks file format and existence before reading patch data
