SCF Compliance Checklist
Every SCF Build Award submission criterion mapped to REAPP's specific response. This page is designed for grant reviewers — no external materials required.
SCF reviewers assess each application based solely on information provided in the submission. No external materials are considered. This page provides a direct mapping of every criterion from the SCF Build Award submission guidelines to REAPP's specific response, with references to the relevant sections of this GitBook for detail.
Full Criteria Mapping
SCF criterion: Must meet all Participant and Submission Eligibility Requirements
AgenTools Labs — independent team, not funded through Matching Fund or Enterprise Fund. No outstanding Research or Academic Grants. No active overlapping grants.
SCF criterion: Demonstrate product-market fit through significant traction or validated need
AP2 launched Sept 2025 with 60+ partners. Stellar published native x402 docs. SDF blog explicitly identifies the agent tooling gap REAPP targets. Team has validated x402stellar integration locally.
SCF criterion: Technically detailed, well-structured, comprehensive — reviewers should not need to follow up
This GitBook covers: protocol architecture, AP2/x402/Soroban fundamentals, full sequence diagrams, Soroban contract interface, SDK package architecture, deployment topology, risk matrix, and budget breakdown.
SCF criterion: Clear use case for Stellar with technical explanation of integration
Stellar is not superficial — it is the settlement layer. Soroban contracts enforce spending policy. USDC via SAC enables sub-cent micropayments. XDR transactions power x402 payment payloads. LaunchTube sponsors fees. Freighter signs mandates.
SCF criterion: Complete architecture outline showing how the system works
See Architecture page: full layer model diagram, AP2 compliance validator decision tree, Soroban data model ERD, security threat matrix, and deployment topology across Railway + Vercel + Stellar.
SCF criterion: Ready to begin development immediately. Defined roadmap, experienced developers, ecosystem tools leveraged
No discovery phase budgeted. Contract interface is implementation-ready. x402stellar validated locally. Alex Astrum — Google Antigravity ADK expertise. Drew Raines — Soroban + agent systems. Max Shama — NEAR NDC $21M+ fund governance.
SCF criterion: Stellar must meaningfully improve core features — not superficial integration or data storage
Stellar provides: (1) 2-5s finality for machine-speed commerce, (2) Soroban __check_auth for non-custodial agent authorization, (3) SAC for native USDC micropayments at $0.001 minimum, (4) fee-bump for gasless client experience, (5) ledger-sequence replay protection.
SCF criterion: If smart contracts included, must include clear plan to open-source them
All Soroban contracts published under MIT/Apache 2.0 at github.com/agentoolslabs/reapp. MandateRegistry, EvaluatorRegistry, and Escrow contracts all open-source from day one. Community audit request submitted separately.
SCF criterion: Only cover development costs for Stellar-integrated components. Reasonable scope/stage/impact
100% development costs. 72% engineering at $135/hr senior rate. 17% product/ecosystem coordination. 11% infrastructure + community bounties. No marketing, no token giveaways, no audit line item.
SCF criterion: Three tranches minimum. Final tranche = mainnet launch. Feasible, well-defined, with costs
Four tranches: T1 (10%/$15k) architecture + PoC, T2 (20%/$30k) MVP demo, T3 (30%/$45k) testnet + full SDK, T4 (40%/$60k) mainnet + 3 integrations + audit. Each tranche has specific acceptance criteria.
SCF criterion: Clear value to Stellar ecosystem. Unique or meaningfully differentiated
No existing project provides AP2 mandate validation + Soroban policy enforcement + x402 settlement + developer SDK on Stellar. See competitive landscape analysis: Coinbase AgentKit (EVM/custodial), Skyfire (Base), Nevermined (no Stellar-native enforcement), x402stellar (payment rail only, no mandate layer).
SCF criterion: If issuing fiat-backed token: Stellar Info File + third-party audit proof
Not applicable — REAPP does not issue any fiat-backed digital asset. Payments use existing USDC (Circle) and XLM.
SCF criterion: Not funded through Matching Fund or Enterprise Fund. No outstanding obligations
AgenTools Labs has not received SDF Matching Fund, Enterprise Fund, Research, Academic, Marketing, Currency Support, or Infrastructure grants. No prior SCF Build Award.
