How to configure addons in Marionette:

Register a new api-user in fireblocks (see https://support.fireblocks.io/hc/en-us/articles/4407823826194-Adding-new-API-users)
Save the private key file on the deployment server (<marionette>/config/secrets/fireblocks_secret.key)
Register webhook url.
Add a new section to the global config file (<marionette>/global/config.yaml)

fireblocks:
  enabled: true
  id: "fireblocks"
  secretFileName: "fireblocks_secret.key"
  apiKey: "xxxx"
  fireblocksServices:
  - baseAsset: ETH_TEST3
    servicePrefix: FIREBLOCKS-GOERLI-PI
    title: Fireblocks Eth Goerli
    subtitle: ERC20
    description: ""
    explorer_address: "https://goerli.etherscan.io/address/#{address}"
    explorer_transaction: "https://goerli.etherscan.io/address/#{txid}"
    invoiceBased: 0
    chainId: 5
    multiCurrency: 1
    isCollectable: 0

enabled - false - quickly turn off the service without clearing template files
id - container name in Docker, name of common service in Moleculer (this service serves webhooks)
secretFileName - Under this name will we mount the file with the private key
apiKey - Fireblocks api key
fireblocksServices - array of fireblocks service (for splitting currencies across blockchains)
baseAsset - token’s name for current blockchain

Following parameters will be used for configure payment interface

servicePrefix
title
subtitle
description
invoiceBased
chainId
multiCurrency
isCollectable

5. Add configuration file <marionette>/templates/config/fireblocks.json.t

{{#if fireblocks.enabled}}
{
    "fireblocks": {
        "secret_file": "{{fireblocks.secretFileName}}",
        "api_key": "{{fireblocks.apiKey}}"
    },
    "fireblocks_path": "/fireblocks/webhook",
    "fireblocks_services": [
    {{#each fireblocks.fireblocksServices}}
    {{#if @index}},{{/if}}
        {
            "baseAsset": "{{baseAsset}}",
            "service_prefix": "{{servicePrefix}}",
            "title": "{{title}}",
            "subtitle": "{{subtitle}}",
            "description": "{{description}}",
            "invoiceBased": {{#if invoiceBased}}true{{else}}false{{/if}},
            "chainId": {{chainId}},
            "explorerAddress": "{{explorer_address}}",
            "explorerTransaction": "{{explorer_transaction}}",
            "multiCurrency": {{#if multiCurrency}}true{{else}}false{{/if}},
            "isCollectable": {{#if isCollectable}}true{{else}}false{{/if}}
        }
    {{/each}}
    ]
}
{{/if}}

6. Add to compose templates <marionette>/templates/compose/paymentInterfaces.yaml.t

{{#if fireblocks.enabled}}
  {{fireblocks.id}}:
    image: gitlab.tunex.io:5050/externals/fireblocks:latest
    hostname: {{fireblocks.id}}
    restart: always
    command: node index.js
    volumes:
      - ../config/fireblocks.json:/app/config.json
      - ../config/secrets/fireblocks_secret.key:/app/{{fireblocks.secretFileName}}
    depends_on:
      - db-bridge
    labels:
      - "traefik.http.routers.fireblocks.rule=Host(`{{base_url}}`) && PathPrefix(`/fireblocks/webhook`)"
      - "traefik.enable=true"
      - "traefik.http.services.fireblocks.loadbalancer.server.port=3000"
      {{#if components.traefik.ssl}}
      - "traefik.http.routers.fireblocks.entrypoints=websecure"
      - "traefik.http.routers.fireblocks.tls=true"
      - "traefik.http.routers.fireblocks.tls.certresolver=myresolver"
      {{else}}
      - "traefik.http.routers.fireblocks.entrypoints=web"
      {{/if}}
{{/if}}

How to configure Fireblocks in setter

After deployment check if the configured data appeared in the configuration blockchains and payment interface lists
For added blockchains on details page push “Create wallet” button.
Configure currencies for fireblocks:

Field “Smart contract/Fireblocks ID” must be contain:

assetId from fireblocks for coin and token

You can only receive a deposit in the configured currencies.

For withdrawals transaction police must be configured (see https://support.fireblocks.io/hc/en-us/articles/7354983580316-About-the-TAP)

N.B. Destination must be a one-time-address.

Be careful, transaction fees for all EVM networks and all supported tokens on each network are paid in the base asset of the network. Fees are withdrawn from the asset wallet that contains the base asset for that EVM network in the same vault account. Therefore, the associated wallet must have sufficient funds to pay the fee.

We recommend using the gas station mode to pay for withdrawals (see details on https://support.fireblocks.io/hc/en-us/articles/360016557960-Fireblocks-Gas-Station)
