 Partially Signed Bitcoin Transactions (PSBTs) are the newest way to vary the creation of basic Bitcoin transactions. They do so by introducing collaboration into every step of the process, allowing people (or programs) to not just authenticate transactions together (as with multisigs), but also to easily create, fund, and broadcast collaboratively. 
 
-> :warning: **VERSION WARNING:** This is an innovation from Bitcoin Core v 0.17.0. Earlier versions of Bitcoin Core will not be able to work with the PSBT while it is in process (though they will still be able to recognize the final transaction). Some updates and upgrades for PSBTs have continued through 0.20.0.

 You have three options for moving through this chapter on hardware wallets: (1) read along without testing the code; (2) install Bitcoin on a local machine to fully test these commands; or (3) skip straight ahead to [Chapter 8: Expanding Bitcoin Transactions in Other Ways](08_0_Expanding_Bitcoin_Transactions_Other.md). We suggest option #1, but if you really want to get your hands dirty we'll also give some support for #2 by talking about using a Macintosh (a hardware-platform supported by [Bitcoin Standup](https://github.com/BlockchainCommons/Bitcoin-Standup)) for testing.

 The methodology described in this chapter for integrating with a hardware wallet depends on the [Bitcoin Hardware Wallet Interface](https://github.com/bitcoin-core/HWI) released through Bitcoin Core and builds on the [installation](https://github.com/bitcoin-core/HWI/blob/master/README.md) and [usage](https://github.com/bitcoin-core/HWI/blob/master/docs/bitcoin-core-usage.md) instructions found there.
