The opportunity
$846T
Global credit markets — the frontier for verified, on-chain credit infrastructure.
Not a Bitcoin L2 · A modular credit-market stack
Building on-chaincredit marketsfor Bitcoin.
Aurora is a modular Bitcoin-backed credit-market stack combining identity, underwriting, loan discovery, and tokenized issuance across Cardano-native rails.
Trusted ecosystem
Built alongside the right partners.
Market opportunity
Bitcoin credit is becoming market infrastructure.
Collateral demand is visible. Institutional scale depends on identity, credit visibility, discovery, and compliant instruments.
Bitcoin-backed lending
$720M+
Active on-chain Bitcoin-backed lending, expanding as institutions seek productive BTC capital.
Aurora Stack
Identity, credit, discovery, and issuance.
Four layers, one orchestration surface. Each layer ships independently and composes into one institutional workflow.
Polaris Wallet
SSI credentials for KYC/KYB and reusable onboarding.
Polaris Wallet enables participants to prove eligibility without exposing raw data. Reusable across the stack and partner integrations.

Aamu Score
Privacy-preserving credit signals via ZK-TLS.
Aamu Score turns off-chain financial data into proof-based credit signals. Underwriters get the inputs they need without raw records.

Sundown
Verified discovery for P2P credit markets.
Built with Sundial. Adds identity proofs, compliance indexing, and lender-side filtering to Cardano P2P lending — without rebuilding the rails.

Inside Sundown
Discovery layer
Surfaces compatible loan opportunities for verified participation.
Compliance-aware indexer
Verifies proof envelopes, issuer authority, and expirations off-chain.
Lender policies
Filter accepted proofs, issuers, jurisdictions, and risk bands.

Solstice
Tokenized bonds and credit instruments via CIP-113.
Programmable tokens carry transfer rules, identity gating, and policy directly. Aurora provides infrastructure, not the license.

Open SolsticeSystem harmony
One credit flow. Four coordinated layers.
Aurora is not four separate products placed side by side. Each layer produces a signal the next layer can use — identity, credit context, market intent, and issuance logic — creating a coordinated flow for Bitcoin-backed credit markets.

Why Cardano
Deterministic settlement for structured credit.
Cardano gives Aurora deterministic settlement, metadata-rich transactions, native assets, and programmable token standards for structured credit.
01Extended UTXO
Predictable, structured transactions.
MoreLess
Cardano's eUTXO model gives clear validation rules and parallelizable, deterministic execution — well suited to financial primitives.
02Metadata-rich transactions
Identity & loan data travel on-chain.
MoreLess
Structured tx metadata lets Sundown attach proofs, eligibility, and indexer anchors without bloating contract logic.
03Native assets
Tokenized credit without smart-contract overhead.
MoreLess
Loans, bonds, and credit instruments use Cardano native assets — fewer moving parts, fewer audit surfaces.
04Programmable token standards
CIP-113 for compliant transfer rules.
MoreLess
Programmable tokens carry identity gating, transfer restrictions, and policy directly — institutional issuance becomes a configuration, not a rebuild.

FAQ
Frequently asked questions.
Aurora is infrastructure for verified, discoverable, tokenized Bitcoin-backed credit. It is not an L2, lender, broker, or replacement for Sundial.
What is Aurora?
Aurora is a modular Bitcoin-backed credit-market stack combining identity, underwriting, loan discovery, and tokenized issuance across Cardano-native rails.
Is Aurora a Bitcoin L2?
No. Aurora is not a Bitcoin L2 or base layer. It sits above existing infrastructure and enables institutional credit workflows around Bitcoin-backed lending.
Does Aurora compete with Sundial?
No. Sundial provides Bitcoin liquidity and base lending infrastructure. Aurora extends that stack with identity, credit signals, loan discovery, and programmable issuance.
How does Aurora work with Sundial?
Sundial provides Bitcoin liquidity infrastructure. Aurora adds identity, credit inputs, discovery, and tokenized issuance. Sundown is the market layer where those capabilities become usable.
Why is Aurora built on Cardano?
Cardano's extended UTXO model, metadata support, native assets, and deterministic execution make it well suited for structured financial transactions and programmable credit instruments.
Does Aurora issue loans or act as a lender?
No. Aurora provides infrastructure. Institutions, issuers, and regulated entities use Aurora's tools within their own legal, licensing, and compliance frameworks.
What is Sundown?
Sundown is Aurora's verified discovery layer, built with Sundial. It adds identity proofs, compliance indexing, and lender-side filtering to Cardano P2P lending.
What is Solstice?
Solstice is the issuance layer for tokenized bonds and structured credit instruments using Cardano programmable token standards such as CIP-113.
