 Blocktank is the Lightning Service Provider (LSP) used by Bitkit. This skill provides full knowledge of its REST API and a utility script to call any endpoint from the command line.
 
-All requests and responses use JSON. Staging's `/regtest/*` routes need basic auth: set `BLOCKTANK_REGTEST_AUTH=user:password` and the script sends it; without it they return `401`. Other routes need no authentication.
+All requests and responses use JSON. Staging's `/regtest/*` routes need basic auth: set `BLOCKTANK_REGTEST_AUTH=user:password` and the script sends it; without it they return `401`. Other routes need no authentication. Debug builds of the app send the same value from Settings > Blocktank Regtest when `BLOCKTANK_REGTEST_AUTH` is set at build time (environment variable, Gradle property or `local.properties`); release builds never carry it.
