OC Cosign

Built by OrangeCheck as a first-party dogfood of the family's identity + payment infrastructure (the auth host, the wallet adapter, Lightning-address primitives). Cosign proves its own backing model in real time — this listing is the model, used on itself.

Live at cosign.ochk.io (launched 2026-06-22). Post a project with full five-field diligence (team, traction, the ask, use of funds, terms). Cosign three ways: join (co-founder interest, double-opt-in), back (sats settled peer-to-peer over Lightning), zap (a lightweight conviction signal). Block-height funding windows run campaigns on the Bitcoin clock no founder or OC can game. Honest sats: pledged vs founder-confirmed settled, with only settled moving the goal bar. A Lightning-QR back flow, reward tiers, stretch goals, and block-stamped milestone celebrations. Settled-velocity discovery rails (trending / almost there / closing soon / just launched) plus an activity pulse. Backer ordinals and conviction tiers (supporter / patron / champion, earned by settled sats). A BIP-322 verified-bitcoiner badge. No custody, no KYC, not a securities platform.

A growth-minded co-founder to make Cosign the default on-ramp for Bitcoiner teams to find each other and raise, plus capital to seed the first cohort. Capital funds a full-time engineering lead, the trust + moderation layer (verified-community affiliations, web-of-trust signals, spam mitigation), recurring monthly backing, and protocol bridges to Geyser and Fountain.

A full-time engineering lead (largest line). Infrastructure + scaling (database, Lightning routing, caching). Trust + moderation tooling (community-affiliation integrations, spam detection, support). Product + design (recurring-backing UI, Geyser/Fountain adapters). A counsel review of the non-securities framing + a privacy audit.

Backing on Cosign is patronage — support, never an investment or a security. Backers get public conviction-tier recognition (supporter/patron/champion, earned by settled sats), off-platform founder-fulfilled rewards (early access, a workshop, roadmap input, your name in the README, a thank-you — the founder chooses and delivers), double-opt-in DM threads with founders, and public first-name activity-pulse attribution. Never equity, shares, tokens, dividends, returns, or profit participation; backing one project never cross-collateralizes another. Stretch goals are founder commitments, not per-backer returns. All sats settle peer-to-peer over Lightning to the founder's own Lightning address; OC never touches the money.
