Stablecoin Issuers — Stablecoin issuer security is the review of the mechanisms that keep a stablecoin worth what it claims — mint and burn authority, redemption paths, reserve and attestation integrity, freeze powers, and supply reconciliation across every chain the token exists on — where an authority failure is indistinguishable on-chain from legitimate issuance.
A stablecoin issuer holds a power no other token issuer does at the same scale: the ability to create liabilities against reserves with a single transaction. Everything about the security model follows from that. The question is not only whether the contract is correct, but who can mint, under what approval, with what limits, with what delay, and what happens on the day one of those keys is in the wrong hands. On-chain, an unauthorised mint and an authorised one look identical.
Multi-chain deployment compounds the problem. The same brand of token exists as native issuance on some chains and bridged representations on others, with different mint authorities, different bridge trust models and different upgrade paths. Total supply becomes a claim that must be reconciled continuously rather than a number that can be read. Several of the largest stablecoin incidents have been reconciliation failures rather than contract exploits.
We review the full lifecycle: mint authorisation and limits, the redemption path a holder actually uses under stress, freeze and blacklist powers and their governance, the attestation pipeline and whether it proves what it says, bridge and cross-chain supply integrity, and the operational controls around every privileged role. We also stress the depeg scenario, because that is when redemption logic and reserve access are tested for real.
We fix a commit hash, agree the in-scope contracts and read your architecture docs, then build a threat model: who the actors are, what the trust boundaries are, and which invariants must never break. Nothing is reviewed against assumptions we have not written down.
Line-by-line review by at least two auditors working independently, focused on authorisation, accounting, upgrade paths, external integrations and the gap between what the code does and what the documentation claims it does. Most critical findings come from this phase, not from tooling.
Static analysers appropriate to the language, plus property-based fuzzing and invariant testing to push the system into states no unit test covers. Tooling is used to widen coverage, never to replace the manual pass.
Candidate findings are proven on a forked network with a working proof of concept. We report what an attacker can actually do and what it costs them, not a theoretical severity label.
Every finding gets a severity rating, reproduction steps, the affected code, the impact in concrete terms and a specific remediation. You get a draft for discussion before anything is finalised.
We re-test every remediation against the original proof of concept and check that the fix has not opened a new path. The final report is yours to publish.
Mint authority, consistently. An unauthorised mint is indistinguishable on-chain from an authorised one, executes in one transaction, and is limited only by whatever quorum, limit and timelock controls exist around the key.
Not as an accounting matter — that is your attestation firm. We review the technical pipeline that publishes reserve data, the on-chain claims derived from it, and what a compromise or error at each step would publish.
Not in themselves; regulated issuers generally need them. What we assess is governance — approval path, timelock, audit trail and what an attacker gains from that role. A blacklist power behind a single hot key is a critical finding.
Significantly. Each deployment has its own mint authority, upgrade path and bridge trust model. Reconciliation design across chains usually becomes the highest-value workstream in the engagement.
Yes, and that is the cheapest point. Authority structure, limits, timelocks and the redemption model are far easier to change before issuance than after integrations depend on them.
A repository or contract address, a commit hash to freeze the scope, whatever architecture or spec documentation exists, and a point of contact who can answer design questions. If documentation is thin we will write our understanding of the system back to you and ask you to confirm it — that step alone catches design-level bugs.
A single token contract is 24–48 hours. A typical dApp or mid-sized protocol runs one to two weeks. Large DeFi systems, L2s, bridges and ZK circuits are scoped per project after we have seen the code. We will give you a fixed timeline with the quote, not an estimate that moves.
