Standards Sdk
Official HOL Standards SDK: first-party, open-source building blocks for decentralized identity
If you're building within the HOL ecosystem, this is the definitive SDK — first-party, open source, and free. Its narrow focus makes it essential for HOL-aligned projects, but teams outside that framework will find little use for it. The lack of a standalone product means you'll need to integrate it yourself.

Skip the HOL Standards SDK if you're not building within the HOL ecosystem, need a production-optimized library, require non-TypeScript language support, or expect a managed identity platform rather than a client-side SDK.
The SDK is free and MIT-licensed, but you'll incur engineering time to integrate and maintain it yourself.
The HOL Standards SDK is free and open source under MIT, making it the lowest-cost route to HOL compliance. Unlike paid identity platforms like Auth0 or Ory (which charge per MAU or per feature), this SDK has zero licensing cost — you only pay for your own integration effort. It's the right choice for HOL-aligned projects that need standards conformance without subscription fees.
In short
Standards Sdk — Official HOL Standards SDK: first-party, open-source building blocks for decentralized identity. Best for Developers building HOL-compatible identity wallets, Issuers implementing credential issuance workflows, Verifiers integrating credential verification. Free to use.

About Standards Sdk
The HOL Standards SDK is the official software development kit for building applications that implement the HOL Foundation's decentralized identity standards. It is a developer library, not a standalone product, designed for teams embedding HOL-compliant credential issuance, presentation exchange, and trust registry interactions into their systems. The SDK abstracts away cryptographic complexity and provides a consistent, audited foundation, making it the go-to choice for identity wallet providers, issuers, verifiers, and enterprise teams seeking compliance alignment. Targeting developers, the SDK is language-agnostic in principle, with initial TypeScript/JavaScript support, and its modular architecture lets teams adopt only the components they need. It includes reference implementations for key HOL standards—credential issuance, presentation exchange, and trust registry—plus a command-line interface for testing and debugging. Versioned releases stay aligned with HOL standards updates, and inline code comments and documentation support integration. As an open-source project maintained by the HOL Foundation, the SDK provides a direct lineage to the specification authors. This first-party status ensures the implementation matches official standards, reducing integration risk and accelerating compliance certification for enterprise users. For teams committed to the HOL framework, this SDK is the most reliable way to ensure conformance. Alternatives from third parties may offer broader features but lack the guarantee of alignment with the standards body's intent. It is ideal for developers and organizations in the HOL ecosystem, not for those seeking a ready-to-use application or a full identity platform. With an MIT license and no cost, it is accessible for open source contributors and commercial adopters alike.
Behind the Verdict
The HOL Standards SDK is a textbook example of a compliance-first developer tool. Its first-party status — maintained by the HOL Foundation itself — is its single strongest asset: you get a direct line to the people who wrote the standards, which drastically cuts the risk of subtle non-conformance. The modular architecture is a thoughtful touch: you can pull in only the credential issuance module, for instance, without dragging in the whole library. The CLI is genuinely useful for prototyping and debugging, letting you simulate issuance and verification flows without spinning up a full identity stack. That said, this is not a production-optimized library. Performance tuning is on you, especially under high throughput. And if you're not committed to the HOL standard, there's little reason to pick this up — it's purpose-built for one ecosystem. The TypeScript/JavaScript-only support is a real constraint for polyglot teams; you'll need to wrap or port to use it from Python, Go, or other languages. Where it shines: government or enterprise identity projects that have already standardized on HOL, startups building HOL-compliant wallets, and auditors who need a trustworthy reference. Where it fails: anyone looking for a quick drop-in identity solution, or teams that want an all-in-one platform with managed APIs and cloud services — the SDK deliberately stays client-side with no backend. If you need a broader alternative, look at general-purpose identity frameworks like Ory or Keycloak, but be warned: they won't guarantee HOL spec alignment. For HOL-specific work, this SDK is the only game in town that comes with the official stamp of approval.

Real-world workflow fit
Concrete scenarios for the personas Standards Sdk actually fits — and what changes day-one when you adopt it.
You're building a HOL-compatible wallet and need to issue credentials to users.
Outcome: You install the SDK, follow the documented issuance reference, and have a working credential issuance flow within a day, tested locally with the CLI.
Your agency is standardizing on HOL for digital IDs and needs to verify presentations from citizens.
Outcome: You integrate the presentation exchange module into your backend, run conformance tests against the reference implementation, and pass compliance review faster thanks to the SDK's alignment with the standard.
You want to contribute to the HOL ecosystem and improve trust registry tooling.
Outcome: You clone the SDK repository, study the modular codebase, and submit a pull request that extends the trust registry reference implementation, supported by inline comments and versioned release notes.
Use Cases
- Integrate HOL credential issuance into your existing identity system.
- Verify HOL presentations from holders in a verifier application.
- Build a trust registry client using the standards-conformant implementation.
- Audit your HOL implementation against the reference SDK.
- Contribute to the HOL ecosystem by improving the SDK codebase.
- Prototype a HOL-compatible wallet with the CLI testing tools.
Limitations
- The SDK currently supports only TypeScript/JavaScript; other languages require wrapping or porting.
- It is a reference implementation, not a production-optimized library, so performance tuning may be needed for high-throughput scenarios.
- No API or cloud service is included – all processing happens client-side.

Where the pricing makes sense
The company stage and team size where Standards Sdk's pricing actually pencils out — and where peers do it cheaper.
The HOL Standards SDK is free and open source under MIT, making it the lowest-cost route to HOL compliance. Unlike paid identity platforms like Auth0 or Ory (which charge per MAU or per feature), this SDK has zero licensing cost — you only pay for your own integration effort. It's the right choice for HOL-aligned projects that need standards conformance without subscription fees.
Setup time & first value
How long it actually takes to get something useful out of Standards Sdk — broken out by persona, not the marketing-page minute.
For a TypeScript/JavaScript developer familiar with identity concepts, getting the SDK installed and running a basic issuance or verification flow typically takes under an hour, thanks to the CLI and reference implementations. Full integration into an existing system may take a few days to a week, depending on architecture alignment.
Switching to or from Standards Sdk
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a third-party HOL implementation: Replace it with the first-party SDK to ensure spec alignment; the modular design lets you swap modules incrementally without a big-bang rewrite.
- ↗To a full identity platform like Ory or Keycloak: If you outgrow the SDK's client-side scope, you'll need to rebuild your identity workflows using the platform's native APIs and data models.
