Intersect — Maintainer Retainer Program

Governance treasury and contributor tracking for Cardano's open source ecosystem. Credential-gated onboarding, milestone-based payments, and full on-chain accountability.

Intersect is the member-based organization that coordinates Cardano’s open source committees and working groups. Their Open Source Committee manages maintainers who build critical infrastructure for the ecosystem.

The problem: how do you onboard, track, and pay 50+ maintainers across multiple committees — with full transparency and zero payment disputes?

Andamio replaces invoice cycles, spreadsheet tracking, and manual treasury execution with credential-gated access, milestone-based smart contract escrow, and automatic fund release on reviewer approval.

Every payment, every approval, every credential — recorded permanently on-chain. No discretionary delays. No disputed records.

Onboard

Maintainers complete a prerequisite course to earn their access credential. No credential, no access — quality starts at the gate.

  • Prerequisite: Accept terms and conditions, complete orientation module, earn on-chain credential.

  • Access: Credential unlocks the Maintainer Retainer Program workspace. No manual approval needed.

  • Outcome: Every maintainer is verified before they touch a single task.

Deliver

Maintainers commit to monthly milestones. Funds move from treasury to escrow automatically when a task is accepted.

  • Commit: Maintainer accepts a task. Smart contract locks the reward in escrow.

  • Evidence: Submit proof of work — artifacts, reports, deliverables aligned to acceptance criteria.

  • Outcome: Clear expectations, transparent progress, no ambiguity about what was delivered.

Pay

Reviewers approve completed work. Smart contract releases funds automatically. No invoices, no payment delays.

  • Review: OSC reviewer validates evidence against acceptance criteria.

  • Release: Approved milestones trigger automatic fund release — up to 3,000 ADA per milestone.

  • Outcome: Complete audit trail. Every payment tied to verified work, recorded permanently on-chain.
