Data Source Settings
Configure which data source is used for firstbits lookups. Changes take effect immediately and are saved server-side.

The admin token is set via the FIRSTBITS_ADMIN_TOKEN environment variable on the server.
It is never stored in the browser.
Active Data Source
PostgreSQL Database
The database password is set via the FIRSTBITS_DB_PASSWORD
environment variable on the server and cannot be changed here.
Blockstream.info API
Mempool.space API
Bitcoin Core Node
Bitcoin node connection details (host, port, RPC user) are configured via environment variables on the server for security — they cannot be changed here without a server restart. See the README for details.
