Samourai Dojo v1.29.0

Apr 9, 2026

This update brings several changes to Samourai Dojo. Namely, the addition of Mempool Space explorer, Addrindexrs deprecation in favor of Electrs and Bitcoin Core 31.0. It also includes a number of bug fixes and minor improvements and updates.

Mempool Space block explorer

This version adds support for Mempool Space block explorer. A user can now choose between Mempool Space and BTC-RPC Explorer as an integrated explorer for their paired wallet.

To use Mempool Space, a user must reconfigure their docker-explorer.conf file:

change EXPLORER_TYPE to mempool_space
update MEMPOOL_MYSQL_PASS with a secure password
update MEMPOOL_MYSQL_ROOT_PASSWORD with a secure password

After that, the user must run ./dojo.sh upgrade for these changes to take effect.

Addrindexrs deprecated, added Electrs support

Addrindexrs has been unmaintained for a long time and has been deprecated in favor of Electrs.

Electrs is a good option for users whose hardware does not have the necessary performance to run Fulcrum while still allowing them to have access to electrum server capabilities.

Users who are currently using Addrindexrs will need to update their docker-indexer.conf file:

change INDEXER_TYPE to electrs

Users who are using Fulcrum before the update do not have to perform any action.

Minor changes and updates

There are also minor changes and updates like lowering the high watermark for block processing to save on RAM usage, fixing host extraction for ipv6 in Knots ban script, updating Bitcoin Core to v31.0 and updating Docker images to latest stable debian versions.
