Pay for governance, not sovereign crypto.
Account systems gate services. Action systems need derived authority.
The SDK and MCP server are open, Apache-2.0, and built to run offline. The web portal adds hosted governance: account access, billing, API-key metering, public records, hosted minting, attestation receipts, ledgers, audit exports, and operational controls for teams.
Limits below apply only to hosted governance: portal-managed public records, API-keyed mint and verify, attestation receipts, ledgers, and audit exports. The SDK and MCP remain free to run outside the hosted service.
