Connect Your Wallet to This Node

grin-wallet · Edit grin-wallet.toml

check_node_api_http_addr = "https://…"

Set check_node_api_http_addr to this node's URL, then restart your wallet. No local node required — the wallet will sync directly via this HTTPS endpoint.

Grim GUI Wallet · External Connections

https://…

Open Grim → go to External Connections
Click ADD NODE
Paste the URL shown above and click ADD
The node should appear with status Available

External connections let Grim use a remote node — no local Grin node process needed.

Remote API checker — test another Grin node's public endpoint

Enter a remote Grin node origin above and click Check…

Sends get_tip to {origin}/v2/foreign directly from your browser · If CORS is missing on the remote node, the browser will block it and show an error
