Overview

SSTS (Solana Security Token Standard) is a security token framework for Solana that combines Token-2022 primitives with configurable verification logic.

Why this model

SSTS is designed for regulated asset issuance without forcing every issuer to deploy and audit a bespoke token contract.

• One reusable core standard program
• Per-mint configuration via program-derived accounts
• Pluggable verification programs for policy enforcement
• Support for corporate action workflows beyond basic transfers

Design goals

• Neutrality: avoid hardcoding any single jurisdiction or asset class policy
• Extensibility: allow issuers to compose local rules with verification programs
• Auditability: keep core behavior predictable and move custom policy to explicit modules
• Operational control: include pause/freeze/delegate controls and receipt/proof tracking

User scope

For most adopters, core program lifecycle is foundation-managed. Integration work focuses on:

• issuer-side transaction and policy orchestration
• verification program composition
• runtime configuration (program IDs, cluster settings, and account context)

Core features in scope

• Token-2022 extension wiring (Transfer Hook, Permanent Delegate, Pausable, Freeze)
• Instruction-level verification configuration (VerificationConfig)
• Verification in introspection and CPI modes
• Corporate actions (split, convert, distribution claims)
• Proof and receipt account patterns for replay protection and claim validation
