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.

SCF Criteria Coverage Assessment
Self-assessment of criterion coverage strength. Product traction is the weakest dimension — mitigated by the validated ecosystem gap and team credentials.

Full Criteria Mapping

Participant Eligibility✓ Met

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.

Product Readiness & Traction✓ Met

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.

Submission Quality✓ Met

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.

Stellar Use Case✓ Met

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.

Technical Integration✓ Met

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.

Build Readiness✓ Met

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.

Stellar Relevance✓ Met

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.

Open Source Plan✓ Met

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.

Budget Alignment✓ Met

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.

Tranche Structure✓ Met

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.

Ecosystem Value & Differentiation✓ Met

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).

Fiat-Backed Token IssuersN/A

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.

Other SDF Funding✓ Met

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.

Ecosystem Value Detail

REAPP Ecosystem Value Chain
REAPP's five value contributions map to four beneficiary groups in the Stellar ecosystem. The open-source SDK and forkable reference agents are the highest-leverage outputs.

Prescreen Risk Assessment

SCF prescreening checks for vague deliverables, inflated budgets, ineligible expenses, missing technical details, and misaligned deliverables. REAPP's prescreen risk profile:

Vague deliverablesLow
Every tranche has specific, verifiable acceptance criteria with named artifacts
Inflated budgetLow
$135/hr senior Web3/TypeScript/Rust rate is market rate. 800 hours over 5 months is conservative.
Ineligible expensesNone
No marketing, no token giveaways, no audit line item, no non-development costs
Missing technical detailLow
Contract interface, SDK package architecture, deployment topology, and sequence diagrams all provided
Deliverable misalignmentLow
All deliverables are Stellar-integrated components. Soroban contracts open-sourced MIT/Apache 2.0
Repo not publicMedium
github.com/agentoolslabs/reapp must be made public before panel review — T1 acceptance criteria
