Overview

walletd is the flagship Sia wallet, suitable for miners, exchanges, and everyday hodlers. Its client-server architecture gives you the flexibility to access your funds from anywhere, on any device, without compromising the security of your private keys. The server is agnostic, so you can derive those keys from a 12-word seed phrase, a legacy (siad) 28-word phrase, a Ledger hardware wallet, or another preferred method. Like other Foundation node software, walletd ships with a slick embedded UI, but developers can easily build headless integrations leveraging its powerful JSON API. Whether you're using a single address or millions, walletd scales to your needs.

Setup guides are available at https://docs.sia.tech

Index Mode

walletd supports three different index modes for different use cases.

Personal

In "personal" index mode, walletd will only index addresses that are registered in the wallet. This mode is recommended for most users, as it provides a good balance between comprehensiveness and resource usage for personal wallets. This is the default mode for walletd.

When adding addresses with existing history on chain, users will need to manually initiate a rescan to index the new transactions. This can take some to complete, depending on the number of blocks that need to be scanned. When adding addresses with no existing history, a rescan is not necessary.

Full

In "full" index mode, walletd will index the entire blockchain including all addresses and UTXOs. This is the most comprehensive mode, but it also requires the most resources. This mode is recommended for exchanges or wallet builders that need to support a large or unknown number of addresses.

None

In "none" index mode, walletd will treat the database as read-only and not index any new data. This mode is only useful in situations where another process is managing the database and walletd is only being used to read data.

Configuration

walletd can be configured in multiple ways. Some settings, like the API password, can be configured via environment variable. Others, like the API port, and data directory, can be set via command line flags. To simplify more complex configurations, walletd can also be configured via a YAML file.

The priority of configuration settings is as follows:

1. Command line flags
2. YAML file
3. Environment variables

Default Ports

• 9980 UI and API
• 9981 Sia consensus

Environment Variables

• WALLETD_API_PASSWORD - The password required to access the API.
• WALLETD_CONFIG_FILE - The path to the YAML configuration file. Defaults to walletd.yml in the working directory.
• WALLETD_LOG_FILE - The path to the log file.

Command Line Flags

Usage:
    walletd [flags] [action]

Run 'walletd' with no arguments to start the blockchain node and API server.

Actions:
    version     print walletd version
    seed        generate a recovery phrase
    mine        run CPU miner
Flags:
  -addr string
        p2p address to listen on (default ":9981")
  -bootstrap
        attempt to bootstrap the network (default true)
  -debug
        enable debug mode with additional profiling and mining endpoints
  -dir string
        directory to store node state in (default "/Users/n8maninger/Downloads/walletd-tmp")
  -http string
        address to serve API on (default "localhost:9980")
  -http.public
        disables auth on endpoints that should be publicly accessible when running walletd as a service
  -index.batch int
        max number of blocks to index at a time. Increasing this will increase scan speed, but also increase memory and cpu usage. (default 1000)
  -index.mode string
        address index mode (personal, full, none) (default "full")
  -network string
        network to connect to (default "mainnet")
  -upnp
        attempt to forward ports and discover IP with UPnP

YAML

All configuration settings can be set in a YAML file. The file should be named walletd.yml in the working directory. All fields are optional.

directory: /etc/walletd
autoOpenWebUI: true
http:
  address: :9980
  password: sia is cool
  publicEndpoints: false # when true, auth will be disabled on endpoints that should be publicly accessible when running walletd as a service
consensus:
  network: mainnet
syncer:
  bootstrap: false
  enableUPnP: false
  peers: []
  address: :9981
index:
  mode: personal # personal, full, none ("full" will index the entire blockchain, "personal" will only index addresses that are registered in the wallet, "none" will treat the database as read-only and not index any new data)
  batchSize: 64 # max number of blocks to index at a time (increasing this will increase scan speed, but also increase memory and cpu usage)
log:
  level: info # global log level
  stdout:
    enabled: true # enable logging to stdout
    level: debug # override the global log level for stdout
    enableANSI: false
    format: human # human or JSON
  file:
    enabled: true # enable logging to a file
    level: debug # override the global log level for the file
    path: /var/log/walletd.log
    format: json # human or JSON

Building

walletd uses SQLite for its persistence. A gcc toolchain is required to build walletd

go generate ./...
CGO_ENABLED=1 go build -o bin/ -tags='netgo timetzdata' -trimpath -a -ldflags '-s -w' ./cmd/walletd

Docker Image

walletd includes a Dockerfile for building a Docker image. For building and running walletd within a Docker container. The image can also be pulled from ghcr.io/siafoundation/walletd.

docker run -d \
	--name walletd \
	-p 127.0.0.1:9980:9980 \
	-p 9981:9981 \
	-v /data:/data \
	ghcr.io/siafoundation/walletd:latest

Docker Compose

services:
  walletd:
    image: ghcr.io/siafoundation/walletd:latest
    ports:
      - 127.0.0.1:9980:9980/tcp
      - 9981:9981/tcp
    volumes:
      - /data:/data
    restart: unless-stopped

Building

docker buildx build --platform linux/amd64,linux/arm64 -t ghcr.io/siafoundation/walletd:master .
