Give unbanked borrowers a portable alternative credit identity whose repayment history is verifiable across lenders. A credit-invisible population gains formal credit access, and a faithful repayer can present that record at any lender instead of starting over.
Turn a trapped, single-lender repayment record into a portable, verifiable credit identity.
01.
Follow the borrower. The DID and VC Ledger module gives each borrower a self-owned credit identity that carries their history from one lender to the next.
02.
Score the credit-invisible. Repayment of microloans, utility bills, and other alternative signals build a credit picture where no formal bureau history exists.
03.
Prove reliability. Each repayment is anchored, so a borrower can present a verifiable track record rather than a lender relying on expensive physical verification.
04.
Share a score, not raw data. The ZK Credentials Kit lets a borrower prove creditworthiness to a new lender without exposing every underlying transaction.
05.
Reuse the history. A repayment record built at a microfinance institution is recognized at a bank, so a good borrower is not treated as a stranger.
06.
Open the door. The Core Banking Accounts module links a proven credit identity to a formal account, bringing the borrower into the banking system.
Follow a credit-invisible borrower from a first microloan to a bank loan approved on portable history.

Cerulea decomposes portable credit into modular contracts. Each layer creates an identity, records repayment, proves creditworthiness privately, and bridges to a formal account.
Portable alternative credit is a horizontal capability. Here is how different actors put a verifiable history to work.
Lend to previously credit-invisible borrowers on a verifiable portable history, expanding the addressable market while cutting the cost of physical verification.
Key Asset Types
Build a borrower's history as a portable asset rather than a captive record, helping good repayers graduate to larger, cheaper formal credit.
Key Asset Types
Own a credit identity that carries their repayment reputation across lenders, turning years of faithful repayment into recognized creditworthiness.
Key Asset Types
Whether you are bridging a lender's loan system or serving borrowers from a basic phone, Cerulea routes both into one portable credit record.
For banks and MFIs on legacy loan systems. Repayment events are translated into signed on-chain credentials through the API gateway automatically.

Portable Credit Record
Building a portable credit system with self-owned identities, alternative-data scoring, zero-knowledge proofs, and a formal account bridge from scratch requires identity and credit engineers and long lender integration. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects credit infrastructure integration benchmarks. Building self-owned identities, alternative-data scoring, privacy-preserving proofs, and a formal account bridge across lenders takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your credit and identity rules into pre-audited WebAssembly binaries and provisions the portable credit ledger and proof layer instantly.
