The DigiByte Integration Guide has been created to help new exchanges, pools, and services get started with the DigiByte Core Wallet.
The current version is 1.3, dated May 2019
You can download the guide here.
Ideally in addition to this guide, exchanges and pools should be encouraged to subscribe to the GitHub project in order to remain up-to-date, especially as there will be forks throughout 2019 with the algo changes etc
Additionally, there are members of the community / DGBAT that can be reached via the Telegram Dev channel, who have previously contacted exchanges / pools to announce the new updates and confirm upgrades have taken place. If this Integration Guide is being downloaded by a service vendor directly, it may be worth leaving contact / escalation details there as a fall-back. Alternatively where community members are providing this to service providers, it may be worth asking for contact and escalation details and passing those on to the applicable people who are in those Telegram channels.
