Summary

  • Move ATA derivation validation before the idempotent early-return check so it runs in both code paths, preventing creation of non-derived ATA accounts.

Audit issue #3 (MEDIUM): validate_ata_derivation was only called inside
the IDEMPOTENT block, so non-idempotent ATA creation never verified the
PDA derivation. Move validation before the IDEMPOTENT check so both
code paths enforce correct ATA derivation.

The ATA derivation validation logic is refactored to perform validation uniformly in both idempotent and non-idempotent modes, then optimize the idempotent path by combining the early-return condition into a single check when the ATA is owned by LIGHT_CPI_SIGNER.

Reorganized validation logic to perform ATA derivation validation upfront for all modes, then combine the idempotent early-return condition into a single check, eliminating redundant re-validation when ATA is owned by LIGHT_CPI_SIGNER.

Summary

  • Move ATA derivation validation before the idempotent early-return check so it runs in both code paths, preventing creation of non-derived ATA accounts.

Audit issue #3 (MEDIUM): validate_ata_derivation was only called inside
the IDEMPOTENT block, so non-idempotent ATA creation never verified the
PDA derivation. Move validation before the IDEMPOTENT check so both
code paths enforce correct ATA derivation.

📝 Walkthrough

Walkthrough

The ATA derivation validation logic is refactored to perform validation uniformly in both idempotent and non-idempotent modes, then optimize the idempotent path by combining the early-return condition into a single check when the ATA is owned by LIGHT_CPI_SIGNER.

Changes

Cohort / File(s)Summary
ATA Derivation Validation Optimization
programs/compressed-token/program/src/ctoken/create_ata.rs
Reorganized validation logic to perform ATA derivation validation upfront for all modes, then combine the idempotent early-return condition into a single check, eliminating redundant re-validation when ATA is owned by LIGHT_CPI_SIGNER.

Poem

✨ Validations dance in perfect stride,
Early returns, no double-check tide,
ATA signer's ownership claims its place,
One unified path—efficiency embraced! 🚀

Run cargo fmt on create_ata.rs and update test_create_ata_failing test 5
to expect error 3 (InvalidAccountData) since validate_ata_derivation now
catches wrong bumps before account creation.
