Tokenized assets connect on-chain permissions to off-chain obligations. The code review should establish which controls are enforced by contracts and which depend on issuers, custodians, or other operators.
Why this scope deserves attention
CoinGecko's RWA Report 2026 documents growth in tokenized assets through the end of Q1 2026. That market evidence makes permissioned-token integrations a relevant security topic, but does not establish demand for any particular auditor. Source 1 describes the market sample; the review framework below focuses on implementation risk.
Review the complete permission system
ERC-3643 specifies interfaces for permissioned tokens, identity and compliance components, and privileged lifecycle actions. Source 2 defines the standard. For an implementation review, include the registries and the parties that can modify them. Reviewing the transfer function alone cannot establish who can ultimately change eligibility or move tokens.
Example: an eligibility change during redemption
Imagine a holder who requests redemption and whose eligibility changes before settlement. Define whether the request remains valid, pauses, or requires intervention. Test that the token balance, pending obligation, and eventual payment cannot disagree. This is an application-design scenario; the correct result depends on the issuer's documented policy and redemption implementation.
Give privileged operations explicit requirements
Create a matrix for minting, burning, freezing, forced transfers, recovery, registry changes, and upgrades. For each operation, identify the permitted actor and the evidence required to authorize it. Test both unauthorized access and authorized actions that violate an economic invariant. Permission checks alone do not prevent a privileged operator from making an accounting mistake.
Keep code assurance distinct from off-chain assurance
A smart contract audit can evaluate implementation of supplied rules and accounting. It does not establish the existence of reserves, custody quality, legal enforceability, or regulatory compliance. Identify the off-chain controls that need independent evidence and avoid presenting a code report as a certificate for those separate obligations.
What to prepare before scoping
Provide the token contracts, registries, upgrade structure, role matrix, and mint-to-redemption lifecycle. Include failed settlement and recovery examples. Document integrations with custodians or attestations as trust assumptions, and agree which interfaces and failure modes the technical review will actually cover.
Review Checklist
- Test eligibility changes during pending operations.
- Reconcile supply, pending redemption, and completed settlement.
- Exercise registry updates, privileged transfers, and wallet recovery.
