Where Daml projects expose risk before deployment

Number 1

Party authorization blind spots

Daml's multi-party permission model is expressive by design, but complex authorization trees are easy to misconfigure – a missed signatory or underconstrained observer can silently expose sensitive financial data.

Number 2

Privacy model misconfiguration

Sub-transaction privacy is one of Daml's most powerful features and one of its most misunderstood; contracts that appear correct in isolation can leak uncommitted data across ledger boundaries when Canton's interoperability layer is engaged.

Number 3

Cross-ledger integration gaps

When Daml contracts interact across Canton's synchronization infrastructure, atomic transaction boundaries can break in non-obvious ways that only surface under specific multi-party execution paths. Our blockchain integration team maps these paths before go-live.

Number 4

Business logic errors in multi-party workflows

Daml models real-world legal agreements – a mismodeled obligation, a missing "choice," or an incorrectly typed contract template can produce invalid counterparty commitments that are nearly invisible until they fail in production.

Number 5

Insufficient test coverage

Simulating multi-party scenarios in Daml requires Scenario scripting and formal verification passes that generic QA frameworks simply don't provide, leaving critical execution paths untested before deployment.

Co-Founder & COO, Uforika

PixelPlex has not only helped us with our smart contract functionality, but they’ve also helped us get those smart contracts audited. Their team has also helped us scope, design, and build a custom wallet and a marketplace for buying and selling NFTs. The most successful result of our engagement is that PixelPlex has created a fully working prototype from scratch.

FAQ

What does a Daml smart contract audit include?

A comprehensive Daml smart contract audit covers template logic review, signatory and observer authorization analysis, privacy model validation, Canton interoperability testing, and integration layer security checks. For projects using Canton.Network smart contract development, we additionally verify Canton-specific protocol configurations and reward coupon logic.

How much does a Daml smart contract audit cost?

Cost depends on template count, multi-party workflow complexity, and depth of Canton integration. We provide a fixed-price estimate after a free scoping call – contact our IT consulting team to book a 30-minute estimate session.

How long does a Daml smart contract audit take?

A focused single-template audit typically takes 1-2 weeks. Multi-party Canton workflows with interoperability testing require 3-4 weeks. Urgent timelines can be accommodated with dedicated resourcing.

Do you audit Daml contracts running on platforms other than Canton?

Yes,we audit Daml contracts on Hyperledger Fabric, Besu, and other Daml-compatible ledgers. Our private blockchain development practice covers the full spectrum of permissioned Daml deployments.

What makes Daml audits different from Solidity audits?

Daml's party-based authorization model, sub-transaction privacy, and multi-ledger execution create a completely different attack surface from EVM contracts. Our smart contract development team works across both paradigms and can articulate precisely where the risk profiles diverge for your codebase.

Do you provide support after the audit?

Yes, every engagement includes a developer briefing alongside the report, remediation planning assistance, and optional re-audit cycles. For ongoing security posture, our DevSecOps consulting team can embed security practices directly into your development pipeline.

Can you audit before deployment and post-deployment?

Yes. Pre-deployment audits catch issues before Canton mainnet. Post-deployment audits are useful for contracts that have evolved, been updated, or are undergoing a compliance review – we scope both engagements the same way.

What compliance standards does your audit cover?

Our reports are structured to support EU AML, MiCA, and GDPR compliance reviews, as well as ISO 27001-aligned security assessments. For full regulatory positioning, our crypto compliance practice can extend the engagement into a complete compliance review.

Do you work with Daml contracts in financial services?

Yes, capital markets, inter-bank settlement, and tokenized asset platforms are our most common Daml audit engagements. Our FinTech blockchain development background means we bring industry context to every finding, not just code-level observations.
