Escrow for Selling a Mastodon Instance With Users

Selling a Mastodon instance is one of the most legally complicated escrow deals possible. You are transferring user data, moderation policies, ongoing federation relationships, and a running server — often with real users who will not be told about the sale until after it happens.

The market is small but active: niche instances with 5,000+ active users in specific interest areas (tech, art, activism, academia) sell for $3,000 to $40,000 depending on activity level and hosting cost.

The user-data legal question#

Under GDPR, instance users must be notified of a data controller change before it happens, and must be given the option to export their data and migrate. Sellers who transfer without notification expose the buyer to fines. Buyers who take over without receiving a clean data-transfer record inherit the liability.

The escrow-protected fix: the seller sends a 30-day notification email to all users before the transfer completes. Escrow funds are held during the notification period. The buyer only takes over on day 31, after the notification window has closed and users have had time to migrate elsewhere if they wish.

Technical transfer#

• Seller provides root SSH credentials for the current hosting environment.
• Seller documents the PostgreSQL backup process and the Redis cache state.
• Buyer migrates the instance to their own hosting under buyer-controlled DNS.
• Seller helps troubleshoot federation issues for 14 days post-transfer.
• Seller retains no admin access after day 14.

Escrow structure#

Given the technical and legal complexity, we recommend a three-milestone escrow: 40% release on server access handover, 40% on successful DNS re-pointing and federation confirmation, and 20% on day 45 after the notification window has closed and no data-transfer complaints have surfaced.
