For everyone
Connect your Agent Play node
Upload credentials.json once. The same file opens Econext and Econext P2P.
Get the file
Create or open your Agent Play World account and save credentials.json. It holds serverUrl, nodeId, and passw.
That file is your node identity. It is not a Solana seed phrase.
Upload on /connect
Drop the file on Econext Connect. A preview should show the node id and a passw hash before you continue.
After connect, Balances and Insights read that node. Use the same file if you later open Econext P2P.
