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.

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. Calm, precise, regulator-readable.

Generate the one-pager for EURC. Platform: Circle Stablecoin Network — Issuer-grade USDC and EURC plus the rails to move them — under one regulated entity.

Product: EURC (Regulated euro stablecoin, status ga) One-liner: MiCA-licensed euro stablecoin issued by Circle, redeemable at par through Circle Mint. Job-to-be-done: Hold and move euros onchain under a MiCA framework, with the same compliance posture as USDC, for European fintechs and PSPs needing a regulated euro rail that isn't dependent on a US dollar bridge. ICPs (ids): fintech, psp, enterprise Differentiators: - MiCA-licensed — first major euro stablecoin issued under the EU framework. - Issued by the same regulated entity as USDC, with identical attestation and redemption mechanics. - Multi-chain coverage on EVMs and Solana from day one. - FX pair to USDC at issuer level — no AMM slippage for institutional flows. Competitors: - EURT (Tether): EURT is thinly circulated and lacks MiCA registration. EURC has the issuer-grade compliance posture European fintechs need to onboard the asset through a bank or regulator. The EURC attestation is a document an EU compliance officer can take to a board; EURT typically isn't. - Agora EUR / Société Générale EURCV: Bank-affiliated euro stables are permissioned and limited to a single bank's counterparties. EURC is open-transfer across chains and customers, which matters for a PSP serving multiple merchant categories or for a treasury team managing FX across banks. - Decentralized euro stables (EURe, etc.): Decentralized euro stables compete on cypherpunk values. EURC competes on regulated posture and same-day fiat redemption. For a regulated PSP, EURC clears compliance; decentralized euros often don't. Proof points: - First major euro stablecoin to obtain MiCA registration. - Available on Ethereum, Solana, Base, Avalanche, Stellar at launch. - Pairs directly with USDC through Circle Mint at institutional rates.

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.
