+Other than Polkadot JS Tools and txwrapper, there are several other libraries that can also be used to submit a signed payload, such as the [Sidecar API](/develop/toolkit/api-libraries/sidecar/#sidecar-api){target=\_blank} or using RPC calls with [`author_submitExtrinsic`](https://paritytech.github.io/polkadot-sdk/master/sc_rpc/author/trait.AuthorApiServer.html#tymethod.submit_extrinsic){target=\_blank} or [`author_submitAndWatchExtrinsic`](https://github.com/paritytech/polkadot-sdk/blob/0ae5c5bbd96a600aed81358339be2f16bade4a81/substrate/client/rpc-api/src/author/mod.rs#L69-L78){target=\_blank}, the latter of which will subscribe you to events to be notified as a transaction gets validated and included in the chain. You can see all the available libraries in the [API Libraries](/develop/toolkit/api-libraries/){target=\_blank} section of the Polkadot Docs.
