01Corporate identity
An operator, not an intermediary.
SDIF exists to participate directly in the networks that underpin digital assets — committing its own capital, running its own infrastructure and building its own understanding of how these systems behave.
The company was formed in Delaware in October 2026 as a privately held limited liability company. It does not raise money, accept outside investors or provide services to customers. Every activity described on this website is conducted for SDIF's own account.
That structure shapes how the company operates. Without clients to serve or products to sell, the measure of the work is the quality of the decisions, the integrity of the infrastructure and the reliability of the controls around both.
02Principal operating areas
Four areas of activity, one operating standard.
Each area is governed by the same framework of documented authority, pre-set limits and security review.

Proprietary digital-asset investment & trading

03Operating philosophy
How SDIF approaches the work.
- P.1
Proprietary by design
Only the company's own capital is deployed. There are no outside investors, no client accounts and no third-party mandates.
- P.2
Controls before capital
Authority, limits and procedures are written down before an activity begins, not reconstructed after it.
- P.3
Infrastructure as discipline
Operating systems directly — rather than only holding assets — creates accountability for security, resilience and correctness.
- P.4
Restraint in disclosure
SDIF describes how it works, not what it holds. Positions, counterparties and wallets are not published.
04Governance & controls
Controls are part of the infrastructure.
Governance at SDIF is treated as an operating system for the company: who may decide, within what limits, through which systems, and with what record.
Documented authority
Decision rights reserved and delegated in writing through the Office of the Founding Partners.
Risk framework
Limits, approvals and review cadences defined before any capital is deployed.
Information security
Access safeguards and separation of public systems from internal records, subject to internal controls.
Operational controls
Continuity planning, reconciliation procedures and internal controls for production systems.
05Research programme
Research that informs operation.
SDIF's research is first an internal discipline. Selected work will be published after internal and legal review.
Network Research
Consensus, validator economics, client diversity and network performance.
R.02Market Structure
Liquidity, venue design, settlement and the mechanics of on-chain markets.
R.03Technical Commentary
Notes on protocol upgrades, tooling and operational practice.
Publications forthcoming
