    Description
    BitcoinAddress
    A Bitcoin address of any standard type, tied to its network.
    BitcoinKey
    A secp256k1 key that signs Bitcoin inputs without necessarily exposing its private key.
    BitcoinNetwork
    The parameters that make an address or key belong to one Bitcoin network.
    BitcoinTransaction
    A Bitcoin transaction: inputs spending previous outputs, new outputs, and the witness data SegWit inputs carry.
    BitcoinTransaction.Input
    One input: the outpoint it spends, its unlocking script, sequence and witness.
    BitcoinTransaction.Output
    One output: an amount in satoshis and the script that locks it.
    Der
    Strict DER (BIP-66) encoding of an ECDSA signature.
    Psbt
    A Partially Signed Bitcoin Transaction (BIP-174, with the BIP-371 Taproot fields): the file hardware wallets, multisig coordinators and watch-only servers pass around until every signer has signed.
    Psbt.Derivation
    One key origin: a public key, the fingerprint of the master it descends from and the path from that master.
    Script
    A Bitcoin script: the locking scriptPubKey of an output, or the scriptSig, redeem and witness scripts that unlock one.
    Script.Builder
    Appends opcodes and pushes to a script.
    Taproot
    Taproot (BIP-341) key tweaking and script trees.
    Wif
    Wallet Import Format: a private key in Base58Check, the form paper wallets and dumpprivkey use.
