Network quick facts
TL;DR
- Use testnet to practice with play money and mainnet when you’re moving real funds.
- The toggle in the header controls everything—vault lists, token IDs, and which explorer links we show.
- Whatever network you pick stays saved locally, so you don’t have to choose again next time.
Side-by-side comparison
| Network | When to use it | Factory account | RPC endpoint | Explorer |
|---|---|---|---|---|
| mainnet | Live environment for real lenders and borrowers. | sudostake.near | https://rpc.mainnet.fastnear.com | nearblocks.io |
What changes when you toggle
- Vaults & requests: You’ll see the vaults that belong to the selected network only.
- Tokens: The default token list (for example, USDC) swaps to the right contract ID for that network.
- Wallet session: Wallet Selector reconnects automatically, so you don’t need to log out or re-approve access.
Practical tips
- Doing a dry run? Start on testnet, mint a vault, and walk through the whole request → repay cycle before switching to mainnet.
- Sharing a link with someone else? Mention the network in your message (“This is a testnet request…”) so they select the right toggle first.
- Need to inspect a transaction? Use the explorer link above—the vault and transaction hashes are the same ones shown in the UI toasts.
