Reference Architecture: Circle
Historical independent public-source study. It does not imply endorsement, commission, internal access, or implementation ownership, and it is not current canonical Architecture.
This wrapper keeps Circle architecture in the Architecture section while preserving the canonical research dossier.
Circle is a reference architecture, not a Jincubator-built system. It is useful as a financial-infrastructure architecture lens across public APIs, wallets, contracts, CCTP, stablecoins, platform controls, and operational boundaries.
Architecture Lens
- API platform surfaces for wallets, contracts, CCTP, gateway, minting, and payment products.
- Stablecoin control surfaces including mint, burn, pause, blacklist, permit, and upgradeability.
- CCTP burn, mint, message, attestation, finality, and replay-protection boundaries.
- Evidence discipline around public docs, OpenAPI schemas, repositories, and labeled assumptions.
