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 circle-stablecoin-network.yml. Nothing in production reads free-form model output.

User prompt
Platform: Circle Stablecoin Network Category: Regulated stablecoin issuer + transport One-liner: Issuer-grade USDC and EURC plus the rails to move them — under one regulated entity. Positioning statement: For fintechs, PSPs, and enterprises that need a regulated dollar with a single counterparty, the Circle Stablecoin Network combines USDC and EURC issuance, CCTP burn-mint transport, and Circle Mint banking integration under one regulated entity (NYDFS, MiCA). Unlike multi-chain platforms (Polygon, Solana) that compose third-party assets and infra, Circle is the issuer — the dollar is theirs, the redemption is theirs, the compliance posture is theirs end-to-end. Bundled value: Circle is the only stack where the asset, the transport, and the on/off-ramp are all the same counterparty. Fintechs and PSPs who care about a single regulated relationship for stablecoin exposure get one contract, one compliance review, one redemption guarantee — instead of composing an issuer, a chain, a bridge, and a banking partner. ICP segments: - fintech: Regulated fintechs — Fintechs needing a single regulated counterparty for stablecoin issuance, custody, and redemption. - psp: PSPs & merchant acquirers — Payment service providers integrating stablecoin acceptance and settlement into existing card-class flows. - enterprise: Enterprise treasury — Corporates running cross-border treasury, payouts, and FX hedging on regulated dollar rails. - developer: Web3 builders — App teams that want USDC/EURC primitives without operating their own treasury or compliance stack. Products: - usdc (USDC): 1:1 USD-backed digital dollar, attested monthly, redeemable at par with Circle. | ICPs: fintech,psp,enterprise | top competitor: USDT (Tether) - eurc (EURC): MiCA-licensed euro stablecoin issued by Circle, redeemable at par through Circle Mint. | ICPs: fintech,psp,enterprise | top competitor: EURT (Tether) - cctp (CCTP v2): Native burn-and-mint transport for USDC and EURC across chains — no bridges, no wrappers. | ICPs: fintech,psp,developer | top competitor: LayerZero - circle-mint (Circle Mint): Regulated banking interface to convert dollars and euros to and from USDC and EURC at par. | ICPs: fintech,psp,enterprise | top competitor: Coinbase Prime Voice traits: regulated-credible, banking-grade-clarity, compliance-first, ships at 95%. Forbidden words (never use): unlocks, revolutionary, degens, to the moon, next-generation, web3-native, leverage, synergy. Reference voice: Brex docs meets Federal Reserve speech.

Generate the one-pager for CCTP v2. Platform: Circle Stablecoin Network — Issuer-grade USDC and EURC plus the rails to move them — under one regulated entity. Platform positioning: For fintechs, PSPs, and enterprises that need a regulated dollar with a single counterparty, the Circle Stablecoin Network combines USDC and EURC issuance, CCTP burn-mint transport, and Circle Mint banking integration under one regulated entity (NYDFS, MiCA).

Fintechs and PSPs who care about a single regulated relationship for stablecoin exposure get one contract, one compliance review, one redemption guarantee — instead of composing an issuer, a chain, a bridge, and a banking partner. Product: CCTP v2 (Cross-chain transport protocol, status ga) One-liner: Native burn-and-mint transport for USDC and EURC across chains — no bridges, no wrappers. Job-to-be-done: Move USDC and EURC between chains without holding bridge risk, wrapped versions, or third-party intermediaries. The token is destroyed on the source chain and re-issued on the destination by Circle, with the same redemption guarantee on either side. ICPs (ids): fintech, psp, developer Differentiators: - Burn-and-mint — no bridge custody risk, no wrapped USDC variants. - Operated by the issuer — same counterparty as the asset itself. - Hooks API for programmable post-transfer actions (deposit, swap, settle) on the destination. - Supported across 12+ chains and growing, all under Circle's compliance posture. Competitors: - LayerZero: LayerZero is general-purpose messaging with per-app implementations of asset accounting. CCTP is purpose-built for Circle assets with the issuer in the loop. LayerZero competes on flexibility; CCTP competes on issuer-grade trust for the dollar itself. - AggLayer (Polygon): AggLayer is multi-asset and multi-chain settlement. CCTP is USDC/EURC-only burn-mint. For a Circle-asset-only flow, CCTP is simpler and counterparty-aligned. For a platform that needs native multi-asset transport (RWAs, local stables, USDT), AggLayer is broader. - Wormhole: Wormhole is a generalized message bus with lock-and-mint wrappers for many assets. CCTP is burn-and-mint just for Circle assets. Wormhole offers wider coverage; CCTP offers a tighter trust model for the specific asset. Proof points: - Live across Ethereum, Avalanche, Arbitrum, Optimism, Base, Polygon PoS, Solana, and more. - Used by major DEXes, wallets, and fintech rails for native USDC routing. - v2 Hooks enable atomic deposit, swap, and settle on destination — production today. Primary metric: CCTP burn-mint transactions per week Voice traits: regulated-credible, banking-grade-clarity, compliance-first, ships at 95%.

Design note · why Zod on every boundary
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.
