The short version

What changed, and why it matters

This commit updates Eclair's Bitcoin library dependency from version 0.48 to 0.49, which internally uses newer versions of bitcoin-kmp and secp256k1-kmp. The code changes only replace old property accesses (like `.txid`) with new method calls (like `.getTxid`) to match the updated library's API. There is no explicit security fix described in the commit, and no verified external references are provided. The change could include bug fixes or security improvements in the upstream cryptographic libraries, but the commit itself does not disclose any specific vulnerability.

Recommended action

Review the release notes and changelog of bitcoin-kmp 0.32.0 and secp256k1-kmp 0.24.0 for any security fixes. Verify checksums and artifact signatures before deploying. Run regression tests on PSBT signing and on-chain transaction handling to ensure the API migration did not weaken the existing anti-tampering checks.

Security signals we found

01

Dependency version bump for Bitcoin and secp256k1 cryptographic libraries
