What is Sign?
Sign is a global digital infrastructure company that powers sovereign nations through secure, large-scale systems for digital currency, digital identity, and real-world asset tokenization. While many blockchain protocols focus on retail speculation, Sign builds the “high-stakes” architecture that governments and regulated institutions rely on to run a country.
Backed by Sequoia Capital, YZi Labs, IDG, Circle, Sign translates cryptographic guarantees into real-world performance. We deliver Digital Sovereignty at National Scale, ensuring that states maintain absolute policy control and privacy while benefiting from the transparency, interoperability, and efficiency of on-chain systems.
What Sign Builds
Sign builds a sovereign-grade infrastructure layer that governments and regulated institutions can reuse across three national systems of money, identity, and capital. Each system is designed for controllable privacy (private to the public, auditable to authorized authorities), national performance, and inspection-ready evidence.
Digital Money System. A sovereign digital money rail that supports CBDC and regulated stablecoins on one national infrastructure, with policy-grade controls, real-time settlement, and supervisory visibility. It enables programmable public finance (salaries, subsidies, pensions, tax refunds) with rule-based execution and measurable outcomes.
Digital ID System. A national identity + verifiable credentials layer where governments can issue crypto-graphically signed claims (ID, licenses, permits, eligibility) that can be verified across agencies and regulated operators. Verification is reusable and interoperable, while privacy is preserved through selective disclosure.
Real-World Asset Tokenization (RWA). A regulated digital asset engine that lets governments issue and manage public instruments (bonds, infrastructure finance, climate instruments, investment funds) as programmable assets with automated distribution, identity-aware access control, and real-time reporting.
Common promise across all three. No matter the program, the system produces standardized evidence of critical actions (who verified what, under what authority, when) so oversight is faster, disputes are reduced, assuring lawful auditability without exposing sensitive data broadly.
| National system | What becomes deployable in practice |
| Digital Money System (CBDC / regulated stablecoins) | A sovereign digital money rail with policy-grade controls: distribution through banks/PSPs/telcos, on- and off-ramps to existing workflows, merchant acceptance, real-time settlement, and inspection-ready reporting for public finance. |
| Digital ID System (verifiable digital identity) | A reusable identity and credentialing layer: one citizen, one verifiable ID; interoperable verification across agencies and regulated operators; privacy-preserving attribute proofs; consistent compliance and auditability. |
| RWA / tokenized public instruments | A compliant capital layer: issuance and lifecycle management of public instruments (bonds, infrastructure finance, funds) as programmable assets with identity-aware access rules, automated distribution (coupons/revenue shares), and real-time transparency. |
Why this matters now. Many national digital pro-grams fail at scale because the foundation is fragmented: money rails are slow and opaque, identity verification is duplicated across registries and operators, and “proof” of delivery becomes manual during audits.
When these foundations are missing, governments cannot reliably enforce policy, prevent leakage, or interoperate across agencies and regulated partners.
What governments get. A reusable national founda-tion with three clear building blocks:
(i) digital money under central-bank oversight (CBDC / regulated stablecoins),
(ii) verifiable identity and cross-agency data exchange (privacy-preserving credentials), and
(iii) regulated real-world asset infrastructure (pro-grammable public instruments). This enables modern delivery and keeps systems sovereign, auditable to lawful authorities, & private by default to the public.
Bottom line
Sign helps governments modernize money, identity, and capital with infrastructure that runs at national scale, holds up under oversight, and stays sovereign over time.
