This guide explains Bitcoin Core walletprocesspsbt RPC in plain English. It shows what the command does, what its result means and what it cannot prove.
TL;DR
- What it is: Bitcoin Core 0.17.0 walletprocesspsbt updated a base64 PSBT with information from the selected wallet and, by default, signed inputs it could sign. Operators could set sign false, choose a sighash type and include known BIP32 derivation paths.
- Why it matters: walletprocesspsbt combines wallet enrichment with optional custody authority. Make that choice explicit, preserve transaction identity and require independent finalisation and broadcast gates.
- Current position: Require a second reviewer and explicit rollback or expiry, and pause payments, signing or network-dependent services until post-change evidence is complete.
Bitcoin Core walletprocesspsbt RPC in simple English
Bitcoin Core walletprocesspsbt RPC: complete true means a complete signature set according to this processing stage. It does not prove finalisation, fee acceptability, recipient identity or readiness to broadcast.
Simple example
A miner is checking Bitcoin Core walletprocesspsbt RPC. Set sign false when the stage should add wallet knowledge only. Bind host, network and wallet endpoint before processing.
Key terms in plain English
- BIP:
- Bitcoin Improvement Proposal: a document describing a proposed rule, standard or process. Its status must be checked separately.
- Bitcoin Core:
- Widely used software that validates Bitcoin and can provide wallet, network and operator tools.
- RPC:
- A command that software sends to a node to request information or a local action.
- PSBT:
- A portable format for passing an unsigned or partly signed Bitcoin transaction between tools and signers.
- Node:
- A computer running Bitcoin software that checks data and communicates with other peers.
Wallet identity
Bind host, network and wallet endpoint before processing. A wrong wallet may add misleading metadata, sign an unintended input or return an apparently harmless incomplete result.
Update without signing
Set sign false when the stage should add wallet knowledge only. This is valuable for watch-only coordination, but metadata can still reveal derivation and ownership relationships.
Signing authority
The default sign true exercises every available suitable key. Unlock only for a reviewed transaction, use a narrow window and relock on every exit path.
Sighash policy
ALL is the default when the PSBT does not specify another type. NONE, SINGLE and ANYONECANPAY variants alter what the signature commits to and require exceptional review.
Derivation privacy
bip32derivs includes paths where known. Provide them only to authorised signers and prevent logs or ticket systems retaining the enriched PSBT.
Complete meaning
complete true means a complete signature set according to this processing stage. It does not prove finalisation, fee acceptability, recipient identity or readiness to broadcast.
How specialists test it
Operators test the command on a non-production node first. They check a normal reply, an invalid request, a timeout and a restart. This shows what the response means and prevents one local result from being mistaken for a network-wide outcome.
Frequently asked questions
What is the main point of Bitcoin Core walletprocesspsbt RPC?
Bitcoin Core walletprocesspsbt RPC: complete true means a complete signature set according to this processing stage.
For Bitcoin Core walletprocesspsbt RPC, what should a beginner know about wallet identity?
Bind host, network and wallet endpoint before processing. A wrong wallet may add misleading metadata, sign an unintended input or return an apparently harmless incomplete result.
For Bitcoin Core walletprocesspsbt RPC, what should a beginner know about update without signing?
Set sign false when the stage should add wallet knowledge only. This is valuable for watch-only coordination, but metadata can still reveal derivation and ownership relationships.
For Bitcoin Core walletprocesspsbt RPC, what should a beginner know about signing authority?
The default sign true exercises every available suitable key. Unlock only for a reviewed transaction, use a narrow window and relock on every exit path.
Conclusion
walletprocesspsbt combines wallet enrichment with optional custody authority. Make that choice explicit, preserve transaction identity and require independent finalisation and broadcast gates.
