Blockchain infrastructure for stablecoin issuers
Reserve management is treasury operations with continuous attestation, not a bank balance screenshot. MiCA, state money transmitter licensing, and banking partner due diligence each impose constraints that reach deep into your contract architecture. The solution includes the on chain systems that satisfy all of them simultaneously.
We solve the infrastructure problems that regulators and banking partners actually ask about.
Reserve management that operates like a regulated treasury
Holding reserves is not the same as managing them. MiCA requires e money token issuers to segregate funds at credit institutions and maintain liquid, low risk portfolios. US state regulators expect reserve composition reporting and independent verification. Banking partners want real time visibility into flows before they will maintain the relationship. Internal dashboards and monthly reconciliation do not satisfy any of these parties.
The solution includes on chain vault contracts that track reserve composition by asset type and custodian in real time, enforce minimum collateral ratios programmatically, and trigger rebalancing when allocations drift beyond policy thresholds. Every deposit, withdrawal, and reallocation records with a permanent audit trail. Your compliance team generates reserve health reports for any regulator at any moment, and your banking partner sees the same data through a permissioned read API.
Mint and burn mechanics that survive a redemption run
Minting must verify collateral deposits and issue tokens without bottlenecks. Burning must release reserves, update circulating supply, and settle redemptions within the same block window. The real test is not normal volume. It is a redemption spike where thousands of holders burn simultaneously and the peg depends on the system processing every request without queue depth degradation or manual intervention.
The system provides permissioned mint and burn contracts that validate collateral before issuance, enforce per epoch supply caps, and process redemptions programmatically with no human gate in the critical path. Minting roles separate across authorized dealers so no single key controls issuance. Redemption flows settle deterministically. Holders verify the burn, the reserve release, and the supply update in a single on chain transaction. The architecture assumes adversarial conditions because that is when it matters.
Continuous proof of reserves, not monthly attestation PDFs
Monthly attestation reports are already outdated by the time they publish. Sophisticated holders and institutional counterparties expect continuous verification. Regulators are moving toward real time reserve reporting requirements. A stablecoin that can only prove backing once a quarter sits at a structural disadvantage against issuers who publish reserve data on chain every block.
The architecture integrates proof of reserves systems that publish collateral composition, custodian balances, and reserve ratios on chain continuously through oracle feeds connected to banking and custodial partners. Holders verify backing independently without relying on issuer reporting. The attestation data is cryptographically signed by the custodian, timestamped, and immutable. Your reserve transparency becomes an auditable, machine readable record that satisfies both regulators and institutional trading desks evaluating counterparty risk.
A licensed e money institution in the EU needed to issue a EUR pegged stablecoin compliant with MiCA Title IV.
The issuer holds an e money license in one EU member state and passports into three others. MiCA requires segregated reserves at credit institutions, redemption at par within one business day, and transaction volume limits that trigger additional capital requirements. Their banking partner requires real time reserve visibility and contractual assurance that blacklist enforcement operates at the contract level, not the application layer. Existing open source stablecoin contracts do not accommodate MiCA specific reserve segregation, mandatory redemption windows, or the compliance controls that the banking relationship depends on.
The solution includes a mint and burn contract where authorized dealers deposit EUR at the custodial bank and the oracle confirms receipt before tokens issue. Redemption settles at par within the on chain settlement window, with the burn transaction releasing a reserve claim that the banking partner honors through the fiat rail. Proof of reserves publishes segregated balances per custodian on chain every block through a signed oracle feed. Blacklist and freeze controls enforce OFAC, EU sanctions, and issuer specific restrictions at the EVM level. Peg monitoring tracks EUR/token deviation across supported venues and triggers circuit breaker alerts when spreads exceed configured thresholds.
