PSBT Builder Explained
A PSBT builder helps you turn basic transaction details into a Partially Signed Bitcoin Transaction that another wallet or signer can inspect and complete. This lightweight version focuses on a simple structure: one input, one recipient, and optional change. That is enough for testing, wallet handoff flows, demos, and front-end product checks. It also outputs both base64 and hex forms, which makes it easier to pass the PSBT into other systems. For more complex multisig or advanced scripting cases you will still want deeper tooling, but this is a useful static-site builder for common simple flows.
