The short version

What changed, and why it matters

This is a routine JavaScript library upgrade. The project moved its bitcoinjs-lib dependency from version 6 to version 7, which changed some internal return types from Buffer to Uint8Array and from number to bigint. The commit adds small adapter functions (like Buffer.from(...) and a bigint-to-number helper) so the rest of the code keeps working without wider rewrites. There is no direct evidence in the commit that this fixes an active security vulnerability; it reads as a compatibility/refactoring change.

Recommended action

Treat as a maintenance/refactor commit. Review the adapter functions (asBuffer, asSatoshiNumber, sha256AsBuffer) for correct handling of Uint8Array views and large satoshi values. Run the existing test suite and PSBT signing tests against a Ledger device or simulator to confirm no regressions in transaction serialization or Merkle hashing. Monitor bitcoinjs-lib v7 release notes for any security advisories, but do not assume this commit itself resolves a known vulnerability.

Security signals we found

01

Dependency upgrade of a core cryptographic library (bitcoinjs-lib v6 → v7)

02

API-adapter pattern wrapping Uint8Array/bigint returns back to Buffer/number

03

No explicit security fix, CVE reference, or vulnerability description in commit message or diff

04

Potential for subtle type-conversion bugs if adapters mishandle endianness, length, or large bigint values
