Crate bitcoin_psbt

Structs

• ExternalSigner
  | Enables interaction with an external signing | device or service, such as a hardware | wallet. See doc/external-signer.md
• PSBTAnalysis
  | Holds the results of AnalyzePSBT (miscellaneous | information about a PSBT) |
• PSBTInput
  | A structure for PSBTs which contain | per-input information |
• PSBTInputAnalysis
  | Holds an analysis of one input from a | PSBT |
• PSBTOutput
  | A structure for PSBTs which contains | per output information |
• PSBT_MAGIC_BYTES
• PartiallySignedTransaction
  | A version of CTransaction with the PSBT | format |

Enums

• PSBTRole

Constants

• MAX_FILE_SIZE_PSBT
  | BIP 174 does not specify a maximum file size, | but we set a limit anyway to prevent reading | a stream indefinitely and running out of | memory.
• PSBT_GLOBAL_UNSIGNED_TX
• PSBT_IN_BIP32_DERIVATION
• PSBT_IN_NON_WITNESS_UTXO
• PSBT_IN_PARTIAL_SIG
• PSBT_IN_REDEEMSCRIPT
• PSBT_IN_SCRIPTSIG
• PSBT_IN_SCRIPTWITNESS
• PSBT_IN_SIGHASH
• PSBT_IN_WITNESSSCRIPT
• PSBT_IN_WITNESS_UTXO
• PSBT_OUT_BIP32_DERIVATION
• PSBT_OUT_REDEEMSCRIPT
• PSBT_OUT_WITNESSSCRIPT
• PSBT_SEPARATOR
  | The separator is 0x00. Reading this in means | that the unserializer can interpret it as | a 0 length key which indicates that this is the | separator. The separator has no value.

Functions

• analyzepsbt
  | Provides helpful miscellaneous information | about where a PSBT is in the signing workflow. | | ———– | @param[in] psbtx | | the PSBT to analyze | | ———– | @return | | A PSBTAnalysis with information about | the provided PSBT. |
• combine_psb_ts
  | Combines PSBTs with the same underlying | transaction, resulting in a single | PSBT with all partial signatures from | each input. | | ———– | @param[out] out | | the combined PSBT, if successful | ––––– | @param[in] psbtxs | | the PSBTs to combine | | ———– | @return | | error (OK if we successfully combined | the transactions, other error if they | were not compatible) |
• count_psbt_unsigned_inputs
  | Counts the unsigned inputs of a PSBT. |
• decode_base64psbt
  | Decode a base64ed PSBT into a PartiallySignedTransaction |
• decode_rawpsbt
  | Decode a raw (binary blob) PSBT into | a PartiallySignedTransaction |
• finalize_and_extractpsbt
  | Finalizes a PSBT if possible, and extracts | it to a CMutableTransaction if it could | be finalized. | | ———– | @param[in] psbtx | | PartiallySignedTransaction | ––––– | @param[out] result | | CMutableTransaction representing | the complete transaction, if successful | | ———– | @return | | True if we successfully extracted the | transaction, false otherwise |
• finalizepsbt
  | Finalizes a PSBT if possible, combining | partial signatures. | | ———– | @param[in,out] psbtx | | PartiallySignedTransaction to finalize | return True if the PSBT is now complete, | false otherwise |
• precompute_psbt_data
  | Compute a PrecomputedTransactionData | object from a psbt. |
• psbt_input_signed
  | Checks whether a PSBTInput is already | signed. |
• psbt_role_name
• sign_psbt_input
  | Signs a PSBTInput, verifying that all | provided data matches what is being | signed. | | txdata should be the output of PrecomputePSBTData | (which can be shared across multiple | SignPSBTInput calls). If it is nullptr, | a dummy signature will be created. |
• update_psbt_output
  | Updates a PSBTOutput with information | from provider. | | This fills in the redeem_script, witness_script, | and hd_keypaths where possible. |
