Run a private government securities settlement chain with atomic delivery-versus-payment, eliminating the T+2 delay and counterparty risk from sovereign bond markets. Bonds settle on the auction date while the central bank gains real-time visibility into primary market activity.
Collapse a multi-intermediary, T+2 settlement chain into a single atomic transaction.
01.
Remove settlement fails. The RTGS Settlement module bundles bond delivery and cash payment into one atomic transaction, so a bond and its payment move together or not at all.
02.
Issue directly to the market. The Securities Lifecycle module runs the primary auction and allots bonds to winning bidders on the auction date itself.
03.
Settle in central bank money. The Core Banking Accounts module holds the cash leg on the same chain, so payment and delivery never rely on a separate reconciliation.
04.
End the T+2 exposure. Because settlement is atomic and immediate, no counterparty carries an unsettled position between trade and settlement.
05.
Watch the primary market live. The central bank reads issuance and settlement as it happens rather than reconstructing it from post-trade reports.
06.
Anchor the sovereign debt stock. Every issuance and settlement is written to the ledger, giving an authoritative real-time record of outstanding government debt.
Follow a single bond from auction allotment to atomic delivery-versus-payment settlement.

Cerulea decomposes sovereign settlement into modular contracts. Each layer issues, allots, settles atomically, and exposes the debt stock without intermediaries carrying counterparty risk.
Atomic sovereign settlement is a horizontal capability. Here is how different actors rely on immediate DvP.
Issue and settle sovereign bonds on the auction date with no counterparty risk, gaining an authoritative real-time record of outstanding government debt.
Key Asset Types
Receive allotted bonds and settle the cash leg atomically, freeing the capital that would otherwise be tied up across a T+2 window.
Key Asset Types
Monitor primary issuance and settlement live and confirm that settlement fails cannot occur, replacing post-trade reconciliation with direct visibility.
Key Asset Types
Whether you are bridging a legacy depository and RTGS system or connecting primary dealers directly, Cerulea routes both into one atomic settlement chain.
For central securities depositories and RTGS operators. Existing settlement instructions are translated into atomic on-chain DvP through the API gateway automatically.

Atomic Settlement Record
Building a sovereign settlement chain with on-chain auctions, atomic DvP, an integrated cash leg, and real-time central bank visibility from scratch requires market infrastructure engineers and long consortium cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects market infrastructure benchmarks. Building an on-chain auction, atomic DvP settlement, an integrated central bank cash leg, and a live issuance view for an average sovereign market takes a baseline of 10 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your settlement and auction rules into pre-audited WebAssembly binaries and provisions the sovereign settlement ledger and central bank view instantly.
