Security Trait Standards for Clarity: Access Control, Pausable Contracts & More

MAJOR UPDATE: From Traits to Templates (Jan 21, 2026)

After incredible feedback from the Clarity WG (Setzeus, Friedger, Gary, Hero Gamer) and @friedger’s technical input, I’m refining this proposal:

New Name: Security Template Standardization

Refined Approach:

Traits verify function signatures (not code inheritance), combined with a three-layer system:

  1. Trait Definitions - Standard security interfaces developers implement (like SIP-009/010)
  2. Template Contracts - Audited copy-paste code for reference implementations
  3. Verification Registry - On-chain tracking of verified secure contracts

Key Advantages:

  • :white_check_mark: Works with current Clarity (no new features needed)
  • :white_check_mark: Mirrors proven SIP-009/010 pattern
  • :white_check_mark: Verifiable security (hash matching + trait implementation)
  • :white_check_mark: Practical for developers (copy template → implement trait → get verified)

Focused Scope (Phase 1):

  • Access Control (Ownable) - Standardized owner/admin patterns
  • Pausable Contracts - Emergency stop mechanisms

Dropping: Reentrancy (not needed in Clarity’s design), Rate Limiting (too contract-specific)


Next Steps:

  • Drafting reference template implementations
  • Preparing trait definitions
  • Will share for technical review before Feb 3 WG

@friedger @Setzeus @HeroGamer @Gary - Would love your thoughts on this refined direction.
