How Moore Johannesburg built a digital asset audit practice.

Moore Johannesburg — a member of Moore Global — partnered with TrustReserve to move beyond manual, fragmented processes and stand up a full digital asset audit

capability: the platform, the workpapers, the training, and the expertise to deliver with confidence.

The firm

An established firm, moving on-chain.

Moore Johannesburg is a leading audit and accountancy firm and a member of Moore Global, one of the world's leading accounting networks. As clients began holding and transacting in digital assets, the firm saw a clear opportunity — and a clear gap.

Servicing crypto exchanges, custodians, and blockchain-based businesses demanded evidence its traditional toolkit simply couldn't produce. Rather than turn the work away, Moore set out to build a dedicated digital asset assurance practice.

"We wanted to lead in digital assets, not react to them. TrustReserve gave us the technology and the assurance expertise to build that capability properly — and stand behind the work."

The challenge

Digital assets are hard to audit.

Wallets, reserves, balances, and transactions are fragmented across chains, custodians, and reporting periods. To build a credible practice, Moore had to solve four problems that off-the-shelf tools leave open.

1. Ownership is hard to prove

   Wallet control, signatures, and custody relationships need evidence auditors can rely on.

2. Balances live across chains

   Teams need one view across assets, blockchains, and reporting periods — not screenshots.

3. Manual evidence doesn't scale

   Spreadsheets and ad-hoc tools slow assurance work and raise review risk with every engagement.

4. Trust requires nuance

   Proof of reserves and wallet evidence need technical accuracy and real assurance discipline.

   
   

How TrustReserve helped

More than the technology - we built the practice alongside them.

The platform is only part of it. TrustReserve's certified team helped Moore deliver from day one — no learning curve, no guesswork — across four moves.

1. Onboard

   Moore could get live on the platform quickly, without a custom integration process.

2. Co-staff and train

   Qualified TrustReserve CAs worked alongside Moore's team on digital asset methodology.

3. Deliver

   Ready-made workpapers and audit-native workflows helped Moore move into real engagements.

4. Grow

   A referral network and repeatable workflows turned the capability into a service line.

TrustReserve supported Moore across four practical areas: co-staffing engagements, providing ready-to-use workpapers, delivering hands-on support from certified accountants, and helping grow the digital asset engagement pipeline.

The outcome

Proof, not promises — in production.

Moore now runs a growing book of digital asset engagements, led by recurring proof-of-reserves attestations for Luno, a global cryptocurrency exchange whose customers can verify the assurance for themselves.

From that flagship engagement, Moore Johannesburg has established itself as a leading digital asset assurance firm in South Africa, serving a widening roster of exchanges, custodians, and crypto-native businesses.

What it could not have taken on before is now a repeatable service line: sharper work, more confident teams, and a new benchmark for transparency.
