Manually broadcasting transactions ourselves

[danielstreet.88]

Hi,

We are using the Solana network.

We would like to know: If a user signs the transaction, can we broadcast the transaction manually ourselves? As opposed to Web3Auth having to broadcast the transaction after the user signs.

Hi Daniel,

Glad to hear you’re exploring the Solana network with Web3Auth!

To address your question: Yes, it is possible for you to manually broadcast the transaction after a user signs it using Web3Auth’s Plug and Play SDK. The SDK is primarily focused on user authentication and key management. Once a user signs a transaction, you can take the signed transaction and broadcast it using your own Solana client or library.

Here’s a general approach you can follow:

1. User Authentication & Transaction Signing: Have the user authenticate and sign the transaction using the Web3Auth SDK.
2. Broadcasting: Use a Solana library like @solana/web3.js to send the signed transaction to the network.

You can find more details on how transaction signing works in the Web3Auth documentation. Also, here is a useful snippet in the Web3Auth Community Forum that discusses similar implementations.

If you have any specific issues with the implementation, feel free to share your code snippets or any error messages you might encounter. That would help us assist you more effectively.

Hope this helps! Let me know if there’s anything else you need.

Hey @danielstreet.88,
Yes, absolutely—you can manually broadcast transactions yourself.

Once the user logs in and you get access to their private key via Web3Auth, you’re free to handle signing and broadcasting however you like. Web3Auth doesn’t do any transaction broadcasting—it’s purely for authentication and key management.
