RPC
RPC endpoints are how Quasarr talks to each chain. You need them for balances, tasks, transfers and the NFT scanner.
What an RPC does for you
With a valid endpoint the app can:
Read balances and contract state
Simulate or send transactions
Scan NFT contracts when you provide addresses
The URL you paste is usually an HTTPS JSON-RPC URL from your provider.
Add an endpoint
Open RPC in the sidebar.
Click Add (primary button with a plus icon).
Enter a name you will recognize, for example
Ethereum mainnet personal.Paste the RPC URL from your provider.
Save.
Always use an RPC that matches the network of the contracts you touch. The app detects the chain automatically from the endpoint you add.
Import and export
Use Import to load a list of endpoints from a file your team shares. Use Export to back up your list.
Treat exported files like configuration secrets if they contain provider keys embedded in URLs.
Test connectivity
Ping one endpoint: use the ping or test control on that row (icon button in the grid).
Ping all: use Ping all in the toolbar to check everything at once.
Health indicators
The list shows latency, success rate and last check time. Green means the endpoint is online, yellow means degraded and red means offline or failing.
Search and maintenance
Use the search box to filter long lists. Edit or delete endpoints from the row actions when a provider rotates URLs or you no longer need a network.
Picking a provider
Common sources include Alchemy, Infura, QuickNode, Ankr and chain-specific public endpoints. Free tiers are fine for testing. Production mints benefit from paid tiers with higher rate limits.
Tips
Add two endpoints per important chain so you can switch if one fails mid session.
If every endpoint for a chain fails, check provider status pages before you blame the app.
Never paste an RPC URL that includes a secret key into a public chat. Rotate the key if it leaks.
