crypto.tt Bitcoin transaction decoder — component licences and provenance

Build date: 12 October 2026
Bundler: esbuild 0.25.12, build-time only, scripts disabled on installation.
Runtime: local browser IIFE; no dynamic imports, wallet methods or remote API calls.
Bundle SHA-256: 0100db78150e7bc5093e8f872f6a2a87f6ca47ed443360a6b4360e4ee2e79ef0
Local package-lock SHA-256: d51af1542e2abe62de343b21cb4d46b12d059c71171eab635d7b0ce226a6b731

Adaptation: wrapper decodes strictly bounded raw hex and matches output templates. Upstream transaction and encoding implementations are bundled without source edits. All input/output values remain local. Examples are explicitly synthetic vectors from bitcoinjs-lib v7.0.1/test/fixtures/transaction.json.
