Architecture

SSTS architecture has clear boundaries between standard Solana programs, foundation-managed core deployments, and issuer policy deployments.

1) Deployment boundaries

ATA is the SPL Associated Token Account program. It is the standard program used to derive and create canonical token accounts for a wallet + mint pair.

2) On-chain account topology (per mint)

3) Transfer enforcement entry points

Ownership and responsibility summary

Why these diagrams

• Diagram 1 answers deployment and trust boundaries.
• Diagram 2 answers which accounts exist and which program owns them.
• Diagram 3 answers where transfer policy is enforced for both transfer entry paths.
