Private subscriptions and creator monetization with Web2-grade UX

Recurring private payments from subscribers to creators - gas-sponsored, set-and-forget, with subscriber identity cryptographically hidden. Tier-gated access via STARK proofs, not wallet scanning. The onchain Patreon that finally works.

What this enables

→Sensitive-content creator economies, onchain for the first time. OnlyFans alone processed $6.6B in 2023 with a subscriber base that depends on absolute privacy from spouses, employers, family. No fraction of this market moves to a public-ledger subscription system. STRK20 opens the entire category - sex work, drug-policy advocacy, mental health, dissident journalism, sex education in restrictive jurisdictions.
→"Set and forget" UX that matches Web2. Session keys (one-time authorization), keepers (automatic charging), paymaster (no gas surprises), natural expiry (graceful end-of-subscription). First onchain primitive that actually resembles Web2 subscription UX, with the added property that the authorization is auditable, time-bounded, and unilaterally revocable by the subscriber.
→Creator confidentiality from competitors. Every existing onchain creator platform exposes per-creator revenue. Rivals benchmark and copy pricing; would-be competitors target high-revenue creators; sponsors negotiate from informational asymmetry. STRK20 puts creator analytics behind the viewing key - same posture as Patreon and OnlyFans.
→Tier-gated access without surveillance. Today, "is this user a $50/mo subscriber?" requires scanning the creator's wallet - a public surveillance act that doxes both parties. Token-gating replaces scanning with a public token-holdings list (same surveillance, different form). STRK20 replaces both with a STARK proof: "I have an active $50/mo subscription to creator C, expiring after D." Discord bot, Telegram gate, or software license verifies the proof and learns nothing else.
→Compliance with FTC "click to cancel" and equivalents. Cancellation is a single session-key revocation. The helper records it. The creator cannot continue charging - structurally compliant by design, meaningfully easier than the Web2 platforms repeatedly hit with FTC enforcement.

What you build

A Subscriptions helper contract managing (subscriber, creator) channels, session-key-authorized recurring charges, keeper-driven charge execution, and cancellation via revocation. A creator-side dashboard (active subscribers, MRR, churn, LTV - all derived from the creator's viewing key, all private to them). A tier-proof verifier library that Discord/Telegram/SaaS gates can drop in. Optional public aggregate counters (total subscriber count, opt-in MRR) for creators who want to show traction without exposing per-tier breakdown.

Why prior onchain subscriptions died

Mirror, Paragraph, Lens, Solana Pay subscriptions, Unlock Protocol, Sablier-as-subscriptions - all credible attempts, all stalled. Every one forced a trade between subscriber privacy, clean cancellation UX, and creator verifiability. Streaming contracts approximate auto-charge but break on cancellation. Token-gated memberships work for access but dox membership. Session keys + channels resolve the trade - first time the structural pieces line up.

Private payroll and treasury disbursement at company scale

A payroll protocol where per-recipient amounts stay private from each other and from the public, but the payer can prove aggregate spend to auditors and each recipient can prove income for tax filings. The compliance model traditional payroll uses, brought onchain without a centralized intermediary.
