The prompts, schemas, and token economics behind every asset.
Each asset is one generateObject call against a Zod schema. The schema enforces shape; the system prompt enforces voice and constraints; the user prompt is hydrated from open-money-stack.yml. Nothing in production reads free-form model output.

Platform: Polygon Open Money Stack Category: Onchain money-movement infrastructure One-liner: API-driven money movement on blockchain settlement — issuance, liquidity, settlement, and interop in one stack. Positioning statement: For fintechs, neobanks, PSPs, and enterprises that need programmable dollar rails at internet scale, the Polygon Open Money Stack is the API-driven money-movement infrastructure that combines deep stablecoin liquidity (PoS), cross-chain settlement (AggLayer), sovereign issuer chains (CDK), and verifiable execution (zkEVM) into one stack. Unlike Tron (single-rail, no programmability), Circle (issuer-only, USDC-only), or Solana Pay (single-chain), the Polygon Stack gives builders a programmable, multi-asset, multi-chain platform with the regulatory posture banks and PSPs require. Bundled value: The point of the stack is not any single product — it is that issuance, liquidity, settlement, and interop compose into one API surface. A neobank can issue on CDK, source liquidity from PoS, settle through AggLayer, and prove compliance with zkEVM — all without integrating four vendors. ICP segments: - fintech: Fintechs & neobanks — Series B–E companies needing programmable dollar rails for treasury, payouts, and embedded finance. - psp: PSPs & payment platforms — Payment service providers and Stripe-class platforms expanding into stablecoin acceptance and settlement. - enterprise: Enterprise issuers — Banks, fintechs, and platforms that need their own permissioned chain for tokenized cash or compliance reasons. - builder: Builders & app teams — Teams building consumer payments apps, marketplaces, or crypto-native fintech products on EVM. Products: - agglayer (AggLayer): Unified liquidity and shared state across heterogeneous chains via pessimistic proofs. | ICPs: fintech,psp,enterprise | top competitor: Optimism Superchain - cdk (Polygon CDK): Deploy your own zk-powered chain that connects to AggLayer at launch. | ICPs: enterprise,fintech | top competitor: Arbitrum Orbit - polygon-pos (Polygon PoS): The largest non-Tron stablecoin EVM home — battle-tested for global payments and fintech use cases. | ICPs: fintech,psp,builder | top competitor: Tron - zkevm (Polygon zkEVM): EVM-equivalent zk-rollup for use cases that require cryptographic settlement guarantees. | ICPs: enterprise,fintech | top competitor: zkSync Era Voice traits: direct, evidence-based, technical-credible, ships at 80%.

Job-to-be-done: Move dollars at internet scale with sub-cent fees, instant finality from a user's perspective, and the deepest EVM stablecoin liquidity outside of Tron and Ethereum mainnet. ICPs (ids): fintech, psp, builder Differentiators: - Battle-tested: trillions in lifetime onchain value, millions of daily transactions. - EVM-equivalent — Solidity tooling, MetaMask compatibility, full DeFi composability. - Deep stablecoin liquidity in USDC, USDT, EURC, plus growing local-currency stables. - Sub-cent fees and 2-second finality make microtransaction-class flows viable. Competitors: - Tron: Tron wins raw USDT supply via low fees and entrenched remittance corridors. PoS wins where buyers need EVM programmability, regulated-fintech posture, multi-asset support beyond USDT, and access to the broader Polygon Stack (CDK, AggLayer) without rebuilding integrations. - Base: Base has Coinbase's consumer distribution — strong in US wallet onboarding. PoS has global liquidity and a more mature fintech-integration story. Both are EVM. Pick PoS for global PSP-class deployments; pick Base if Coinbase wallet UX is the primary distribution lever. - Solana Pay: Solana Pay is fast and cheap but locks you into the Solana stack. PoS is EVM, multi-chain via the Polygon Stack, and integrates with existing fintech infrastructure. Use Solana for single-chain consumer payments apps; use PoS for platform plays needing portability. Proof points: - Top-3 EVM chain by stablecoin supply globally. - Active integrations with Stripe (legacy), Revolut, Mastercard programs. - Sub-cent median fees sustained even during volume spikes.

The AI's job is to generate copy that fits a known shape. If the model deviates — a missing field, a string too long, a wrong number of email steps — the call fails closed and we know about it. Free-form output would compound errors silently and the PMM would lose trust in the pipeline.
