Walkthrough

The pull request refactors dynamic imports in the signature validator to use static imports. The base58btc module is now imported directly at the top of the file, and two functions are updated to use the imported module instead of awaiting lazy initialization logic.

Changes

Cohort / File(s)	Summary
Import refactoring infrastructure/signature-validator/src/index.ts	Replaced lazy dynamic import of base58btc with static import. Removed base58btcModule and getBase58btc() helper. Updated decodeMultibasePublicKey() and decodeSignature() to use statically imported base58btc.decode() directly instead of awaiting async imports.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

• Verify the static import path is correct and available
• Confirm both function updates correctly replace the async await pattern
• Check that error handling behavior is preserved

Poem

🐰 From lazy loops to imports so clean,
Static at last, no await in between!
Base58btc now greets us up front,
Refactored with care, a speedy stunt!
Hopping through code, we improve every day! ✨
