Cross-Border Stablecoin Register (CBSR)

An open, versioned register of how twelve jurisdictions regulate stablecoins: the United States, the European Union, the United Kingdom, Singapore, Hong Kong, mainland China, Brazil, Switzerland, the United Arab Emirates, Taiwan, Japan and South Korea. Maintained by Yunjie Fan as independent research. Website: cbsr.site.

The register is a research reference. For legal decisions, check the cited source and its date with a qualified adviser.

What a record contains

Each record is one proposition about one jurisdiction, instrument and dimension. It keeps the following information in separate fields.

• Kind of claim (claim_class): a rule of law (tier1_legal) or a market or operational fact (tier2_operational).
• Strength of the source (evidence_tier): confirmed against the official text (resolution_text), core point confirmed (mixed), resting on practitioner analysis (firm_summary), or unverified.
• Binding status: for example in force, enacted but not yet in force, or proposed; the full list of values is in METHODOLOGY.md.
• Source: the instrument and pinpoint, with a URL where one has been recorded.
• Source check and review state: the date of the last check against the source, marked unknown where none has been recorded, and the review the record has had.

Current state

Status: v0.11.0 (data snapshot generated 20 August 2026).

• Coverage reports the evidence tiers, source URLs and the records that meet the structural test for citable law.
• Source-check report records current, stale and missing checks. No record has a current source check or an independently attested second review, so the decision-ready subset is empty.
• Corridor analysis reports where the rule engine reproduces the hand-worked corridors and jurisdiction-pair categories, and where it differs (EU–UK and UK–US).
• Snapshot metadata lists the record, corridor and MCP tool totals. The v0.11.0.post1 engineering update uses the same data snapshot.

Use

• Download the dataset. The analysis layer is under analysis.
• Query the dataset with typed MCP tools. In v0.11.0, citable_law() returns an empty result.
• Explore the CBSR mapper.
• Find open tasks or read the contribution guide.

Use the hash-locked development dependencies to verify a checkout.
