I want to learn more about PSBTs ( Partially Signed Bitcoin Transactions )

PSBT stands for Partially Signed Bitcoin Transaction. It's a format for transactions that are not fully signed, allowing for a transaction to be passed around multiple parties before it is complete. This format facilitates multi-signature setups, where multiple parties need to sign a transaction before it can be broadcasted to the Bitcoin network. It's particularly useful for improving security and flexibility in managing Bitcoin transactions, enabling a smoother coordination between different wallets and platforms.
