You have several wallets and use each of them often. When you apply for an unsecured loan, the protocol only looks at the address you submit—it has little money and a short history, so you are rejected right away.

You know you have enough assets in another wallet, but the protocol does not accept that. Because on-chain credit systems treat each wallet address as a separate individual by default, they cannot automatically recognize that "these two addresses belong to the same person."
This is not the system being difficult. On-chain addresses are pseudonymous, so a protocol cannot guess that address A and address B belong to the same person. But if you manually "bind" them together, credit scoring can be calculated on a combined basis.
Why Binding Addresses Improves Credit Scores
The core logic of credit scoring is: the more complete the data, the more accurate the assessment. Traditional credit scoring looks at a person's full credit history, not just one credit card record. On-chain credit is the same—one wallet may have only a few lending records, while another wallet holds large collateral assets. Viewed separately, both scores are low; combined, they show the real full picture.
Spectral Finance allows users to bundle multiple addresses under the same "Non-Fungible Credit (NFC)" token. The system then aggregates data from all addresses to calculate a unified MACRO score. The main wallet's credit score can improve because both the length and diversity of credit history increase. Creditlink offers a similar capability by generating a portable credit identity through "cross-chain activity aggregation."
How to Do It
[What to do]: In a credit protocol that supports multi-address binding, link multiple wallet addresses under your control to the same credit identity.
[How to do it]:
Check whether the protocol supports binding: Currently Spectral's NFC clearly supports bundling multiple addresses. Other protocols, such as Credence Protocol's cross-chain multi-address analysis, are also exploring similar capabilities.
Choose a main wallet: Decide which address will be the "main wallet" that receives the credit token and score. This address will become your "credit identity entry point" in the future.
Add other addresses: Follow the protocol's instructions to add your other wallet addresses. Note: Spectral currently does not support adding or removing addresses after an NFC is generated, so confirm in advance.
Request a credit assessment: Submit a scoring request, and the system will calculate a unified score based on the history of all addresses.
[Completion standard]: The system shows that your credit score has been updated, is higher than any single address's score before binding, and multiple addresses under your control are linked to the same NFC token.
Common Failure Reasons and Risk Reminders
No changes after binding: Spectral's NFC does not support adding or removing addresses after creation; you can only destroy it and start over. Think carefully about which addresses to include before binding.
Privacy concerns: Binding addresses means "publicly admitting that these addresses belong to the same person." Some protocols may support hiding the binding relationship, but at the protocol level it can still be traced. If address isolation matters a lot to you, binding may not be suitable.
Not all protocols recognize it: Even if you bind multiple addresses in one protocol, other lending protocols may not adopt this credit score. The "portability" of credit scores is still a difficult industry problem.
If you want to merge credit records from multiple wallets for "inheritance planning," consider this: do your heirs need to know you have this many addresses? Binding means future heirs will also need to manage all assets and authorizations tied to these addresses. If too much information causes operational mistakes, it may do more harm than good.

How to Verify After Completing the Operation
After binding addresses, go to the credit protocol's dashboard and check the "linked address list" to confirm all intended addresses are shown. Then submit a scoring request and compare the score before and after binding. If the score does not improve, it may mean the new address data was not included in the calculation, and you need to check again.
