chainalysis

Chainalysis Ruby Client

A Ruby wrapper for the Chainalysis Transaction Monitoring API. This client library provides a simple, intuitive interface to interact with Chainalysis's API services.

Installation

Add this line to your application's Gemfile:

gem 'chainalysis'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install chainalysis

Usage

First, initialize a client with your API key:

require 'chainalysis'

client = Chainalysis::Client.new(api_key: 'your_api_key')

Registering a Transfer

# Register a new transfer
response = client.register_transfer(
  user_id: 'user123',
  network: 'Bitcoin',
  asset: 'BTC',
  transfer_reference: 'tx_hash:address',
  direction: 'received',
  # Optional parameters
  transfer_timestamp: '2024-01-10T15:30:00Z',
  asset_amount: 1.5,
  asset_price: 45000.00,
  asset_denomination: 'USD'
)

# The response includes an externalId that you can use to query the transfer
external_id = response['externalId']

Managing Transfers

# Get transfer details
transfer = client.get_transfer(external_id: 'transfer_external_id')

# Get transfer exposures
exposures = client.get_transfer_exposures(external_id: 'transfer_external_id')

# Get transfer alerts
alerts = client.get_transfer_alerts(external_id: 'transfer_external_id')

# Get transfer network identifications
identifications = client.get_transfer_network_identifications(external_id: 'transfer_external_id')

Managing Withdrawal Attempts

# Register a withdrawal attempt
response = client.register_withdrawal_attempt(
  user_id: 'user123',
  network: 'Bitcoin',
  asset: 'BTC',
  address: '1EM4e8eu2S2RQrbS8C6aYnunWpkAwQ8GtG',
  attempt_identifier: 'withdrawal_001',
  asset_amount: 2.5,
  attempt_timestamp: '2024-01-10T15:30:00Z'
)

# Get withdrawal attempt details
withdrawal = client.get_withdrawal_attempt(external_id: 'withdrawal_external_id')

# Get withdrawal attempt exposures
exposures = client.get_withdrawal_attempt_exposures(external_id: 'withdrawal_external_id')

# Get withdrawal attempt alerts
alerts = client.get_withdrawal_attempt_alerts(external_id: 'withdrawal_external_id')

# Get high risk addresses
addresses = client.get_withdrawal_attempt_high_risk_addresses(external_id: 'withdrawal_external_id')

# Get network identifications
identifications = client.get_withdrawal_attempt_network_identifications(external_id: 'withdrawal_external_id')

Categories and Administration

# Get all categories
categories = client.get_categories

# Get internal users (requires ORGADMIN permission)
users = client.get_internal_users

Error Handling

The client includes custom error classes for different types of API errors:

begin
  client.get_transfer(external_id: 'invalid_id')
rescue Chainalysis::NotFoundError => e
  puts "Transfer not found: #{e.message}"
rescue Chainalysis::AuthenticationError => e
  puts "Authentication failed: #{e.message}"
rescue Chainalysis::RateLimitError => e
  puts "Rate limit exceeded: #{e.message}"
rescue Chainalysis::BadRequestError => e
  puts "Bad request: #{e.message}"
rescue Chainalysis::ApiError => e
  puts "API error: #{e.message}"
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install.

Running Tests

$ bundle exec rspec

Tests use VCR to record and replay HTTP interactions. To record new interactions, delete the corresponding cassette file and run the tests.
