To connect your wallet to the Sui Testnet or any other network, you’ll need the right RPC URLs (Remote Procedure Calls). These URLs allow your app or wallet to communicate with the Sui network. Here's how you can find the right ones:

1. Official Sui Documentation

Start by checking out the official Sui docs. They usually list the RPC endpoints for different networks (Testnet, Devnet, Mainnet, etc.). You can find this info here: Sui Developer Docs.

2. Public RPC Endpoints

For the Testnet, you can use the official public endpoint like this:

https://fullnode.devnet.sui.io:5001

This is the standard RPC URL for connecting to the Sui Testnet.

3. Self-hosted RPC Nodes

If you want to go the extra mile and set up your own RPC node, Sui allows you to run your own local instance of Testnet or Devnet, giving you more control over the setup.

4. GitHub and Community Resources

Sui’s GitHub repositories might have additional RPC setup details. You might also find more custom RPC URLs or configuration examples in the issues, discussions, or README files on GitHub. Here’s the link: Sui GitHub.

You can also ask around in Sui’s Discord or Telegram if you’re looking for more specific or unofficial RPC endpoints shared by the community.

5. Wallets and Custom RPCs

If you’re using a Testnet wallet, there might be an option in the settings to add or switch to a custom RPC endpoint. Some wallets make this process pretty straightforward.

In Short:

• Testnet RPC URL: https://fullnode.devnet.sui.io:5001
• For more, check the Sui docs, GitHub, or community channels for the latest updates or custom RPCs.

If you need anything more specific or run into issues, let me know!

You'll primarily find the official public Testnet RPC URL for the Sui network. There aren't many 'custom' public ones widely available for Testnet; usually, if you need a different one, it's because you're running your own full node.

SUI RPCs (Remote Procedure Call endpoints) are the URLs that your wallet or application uses to connect to the Sui blockchain network (Mainnet, Testnet, Devnet, or a custom node). These endpoints allow your wallet—like Sui Wallet or Ethos—to query blockchain data, send transactions, and interact with smart contracts.

If you're looking for custom RPC URLs that you can use in your Sui Testnet wallet, here’s how you can find or use them:

Official Sui Testnet RPC URL (public):

https://fullnode.testnet.sui.io

This is the default RPC used by most wallets and SDKs when connecting to Sui Testnet.

✅ Where to Find Custom or Third-Party RPCs

If you're looking for alternative or faster endpoints, here are some options:

• Node providers like:

  • Blast: https://docs.blastapi.io/docs/sui-get-started
  • QuickNode: https://www.quicknode.com/chains/sui
  • Nodereal: https://docs.nodereal.io/docs/sui
  • Triton One: https://triton.one/ (Mainnet/Testnet RPC access)

Each provider typically offers a free and a paid tier. Once registered, you'll get a custom RPC URL like:

https://sui-testnet.blastapi.io/YOUR_API_KEY

These custom RPCs are useful when:

• You need faster response times
• You’re rate-limited on the default public node
• You want to monitor logs, metrics, or performance

🛠️ How to Use in Sui Wallet

To use a custom RPC in your Sui Wallet extension:

1. Click the network selector in the top-left corner.
2. Choose "Add Custom RPC" or "Custom".
3. Paste your custom URL (e.g., from Blast or QuickNode).
4. Save and switch to that network.

You can find the latest official endpoints on Sui’s official docs: https://docs.sui.io/build/network-endpoints

Typically, for Sui testnet, you'd use the official fullnode RPC: https://fullnode.testnet.sui.io:443. There aren't usually many other public custom RPC options widely available; most people just rely on the official one or host their own if they need something truly custom.
