# Open Source Web3 Client Libraries

If you're looking to sign Picket nonces manually, leveraging open source client libraries can help you do that. This is more advanced and these are not required if you're just looking to authenticate wallets and token gate off-chain content, for that you can use a [picket library](/picket-docs/reference/libraries-and-sdks.md) for the best integration experience.
