Environment variables
  • THREE_WS_BASEBase URL of the three.ws API that serves /api/sns and /api/threews/subdomain. Override only when self-hosting or targeting a preview deployment.
  • THREE_WS_TIMEOUT_MSPer-request timeout in milliseconds. Resolution and availability checks hit a Solana RPC pool, so the default leaves room for a cold lookup.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
