A CryptoCurrency Security Standard Implementer is an expert in the CCSS. A CCSS Implementer is responsible for designing, building, and operationalizing secure digital-asset systems that comply with the CryptoCurrency Security Standard. They translate CCSS requirements into real-world architecture, workflows, and controls so an organization can meet the standard in practice.
C4 has two tracks related to the CCSS.
To find out which path is right for you, take our self assessment.
Every prospective CCSSI must take C4’s official CCSS Foundations and CCSSI Implementer Training courses. These live, instructor-led online trainings build the practical, real-world skills needed to securely design and operate systems that align with the CCSS.
During the 2-day Foundations course, candidates develop a strong baseline across all CCSS requirements. They learn the structure of the Standard, key terminology, threat models, and how each aspect functions in practice through case studies and fictional systems. Foundations ensures every candidate speaks the same language before progressing into implementer-focused training.
During the 2-day Implementer course, candidates learn how to implement CCSS controls in real systems while meeting each entity where it is. They learn how to assess a system’s current state and map gaps to CCSS requirements; choose appropriate control designs such as HSM vs MPC, HD vs JBOK, and various policy-engine patterns; and build an Implementation Approach that sequences work, assigns owners, and manages dependencies. Candidates also practice drafting the practical artifacts required for successful implementation, including procedures, architecture diagrams, and key material compromise plans.
Together, these four days give CCSSI candidates both the knowledge and the practical skills required to build systems that meet the CryptoCurrency Security Standard.
Once you've completed the training, you will have 6 months to take your exam from the date of purchase. Once you begin the exam you will only have 90 minutes to answer all 100 questions.
The exam includes 100 multiple-choice and true/false questions covering each of the 41 aspect controls of the CCSS. The exam is time-limited to 90 minutes. A passing grade of 70% is required for certification. If you fail the exam, you will have one retake. After that, you can pay to take the exam again. You will not be certified until you have successfully passed the exam.
During the exam, you will be asked questions related to a real-world scenario. Please download the CCSSI Exam Scenario and review it before beginning this exam.
Because CCSSI is a new designation as of November 2025, every Implementer will be earning this certification for the first time. All CCSSIs must renew annually to show they understand the current version of the Standard and the latest best practices for secure system implementation.
The renewal path depends on which trainings the CCSSI has previously completed.
1. First-time CCSSIs (all candidates for the initial launch)
Since CCSSI is new, all prospective CCSSIs will complete both the CCSS Foundations and CCSSI Implementer Training before taking the exam. For future renewals, the specific requirements will depend on updates to the Standard. Renewal discounts will apply to any required training; the exam is included.
These courses ensure every active CCSSI has the same baseline knowledge and implementation approach.
2. Future CCSSIs who have already completed official training
After the first cohort, any CCSSI who has already completed C4’s official Foundations and Implementer Training will have a lighter renewal path. Depending on the scope of changes in the latest CCSS version release, they may only need to complete a short update module, or no training at all. When updated training is required, it focuses solely on new and revised requirements and is significantly shorter than the full initial training. Recertification is dependent on passing the most current CCSSA exam.
Recertification requires passing the most current CCSSI exam.
Certified CCSSIs receive a 25% renewal discount via the email used for prior registration, beginning 6 months before their expiration date. Because training is required to renew, the discount applies to the training cost, and the exam fee is included.
If your CCSSI certification is active at renewal:
You will receive the 25% discount on the required training. The training price includes the exam.
If your CCSSI certification has lapsed:
The 25% discount does not apply. Registration is at the standard training price, which still includes the exam.

A CryptoCurrency Security Standard Auditor is an expert in the CCSS. CCSSAs are able to apply the CCSS standard to any information system that uses cryptocurrencies, calculating a grade for the system according to the CCSS.
C4 has two tracks related to the CCSS.
To find out which path is right for you, take our self assessment.
Every prospective CCSSA must take C4's official CCSS Foundations and CCSSA Training courses. These are live, instructor-led, online courses that build real, applicable skills.
During the 2-day Foundations course, candidates build a strong baseline across all CCSS requirements. During the course, attendees learn the structure of the Standard, key terminology, threat models, how each aspect works in practice through case studies and simple fictional systems, and more. The Foundations course ensures everyone speaks the same language before moving into auditor-specific training.
During the 2-day Auditor course, candidates focus on how to audit against the CCSS. Candidates learn how to evaluate evidence, identify gaps, apply CCSS requirements in a mock-audit scenario environment, and determine certification levels. They learn how to assess real systems, understand scope boundaries, and uphold auditor impartiality.
Together, these four days give CCSSA candidates both the knowledge and the practical auditing skills needed to evaluate cryptocurrency systems against the CCSS.

CCSSA certification must be renewed every year. To renew, CCSSAs need to show they understand the current version of the CCSS. The renewal path depends on prior certification date.
1. CCSSAs certified before the official training launched
If a CCSSA certified prior to the launch of C4’s official CCSS Foundations and CCSSA Auditor Training, both courses must be completed prior to renewal. Renewal discounts will apply to the training; exam is included.
These courses ensure every active CCSSA has the same baseline training and auditing approach.
2. CCSSAs certified after completing the official training
If a CCSSA has already completed C4's official Foundations and Auditor Training, the renewal process is much lighter. Depending on the scope of changes in the latest CCSS version release, they may only need to complete a short update module, or no training at all. When updated training is required, it focuses solely on new and revised requirements and is significantly shorter than the full initial training. Recertification is dependent on passing the most current CCSSA exam.
CCSSAs who are currently certified receive a 25% renewal discount via the email address used for prior registration 6 months before their expiration date, and that discount applies under the training-based renewal process. Because training is now required to renew, the 25% discount applies to the training cost for currently certified CCSSAs, and the exam fee is included in the training.
