Real-World Credit Score Bridge Attestation Tool

WHAT IT DOES

Real-World Credit Score Bridge Attestation Tool enables authorized issuers to attest real-world credit scores from traditional credit bureaus (e.g., Experian, Equifax) or alternative data providers, bridging off-chain credit data to on-chain identities. The tool reads the credit bridge contract to verify data provider status, oracle availability, and attestation schemas, then issues credit score attestations (EIP-4973 soulbound or EIP-1155 badges) that represent a user's traditional credit score on-chain. This enables DeFi lending protocols to offer undercollateralized loans based on real-world creditworthiness, with support for batch attestations to multiple users in a single transaction using the shared BotGentz bulk sender contracts.

This tool is essential for DeFi platforms, credit protocols, and lending DAOs that want to incorporate traditional credit scores into their risk assessment models, enabling undercollateralized borrowing for users with strong off-chain credit histories.

HOW TO USE

1. Connect your EVM wallet to the network where the credit bridge contract is deployed.

2. Enter the bridge contract address and the data provider/oracle ID (e.g., "experian").

3. Add users by entering address, credit score, and expiry date per line.

4. Click "Check Users" to verify which users have credit data available from the oracle—the tool checks data provider status and existing attestations.

5. Review the user status table showing data availability and attestation status.

6. Click "Attest Scores" to approve the fee payment and mint credit score attestations to all eligible users.

7. Track progress via the status bar and confirmation of the transaction hash upon completion.

TECHNICAL MECHANISM

The tool reads the credit bridge contract using view functions: getDataProviderStatus(providerId) to check if the oracle is active, getAttestation(address) or hasCredential(address) to check existing attestations, and getSchema() for the attestation schema. It verifies whether the user has credit data available from the provider and whether they already have an attestation. For issuance, the tool attempts batchAttest(recipients[], scores[], providerId, expiry) if available, falling back to sequential attest(recipient, score, providerId, expiry) calls. The tool uses the BotGentz bulk sender contract to handle fee payments, reading fee() live from the sender contract and displaying the owner before execution. Gas estimation applies a 20% buffer, and actual gas costs are calculated from receipt.effectiveGasPrice.

WHAT IT CANNOT SEE

This tool cannot verify the accuracy of off-chain credit score data from traditional bureaus—it relies on the data provider and oracle to supply accurate information. It cannot guarantee that the data provider or oracle is trustworthy; the oracle may be compromised or provide stale data. It cannot verify that the user's identity matches the off-chain credit record; the tool assumes the identity verification has been performed off-chain. It cannot revoke attestations if the user's credit score changes; revocation requires separate governance actions. It cannot manage attestations across multiple credit bureaus or data sources; each provider may require different handling. It cannot validate the user's legal or regulatory compliance; the tool assumes the issuer has performed the necessary checks. It cannot account for data latency or oracle failures; stale or missing data may result in incorrect attestations.

PLEASE NOTE

EVM chains only. This tool requires that the credit bridge contract implements the standard interfaces for oracle-based attestation. The tool attempts multiple function signatures for compatibility. Attestations are irreversible—ensure the user's data is accurate before attesting. The fee for the bulk sender contract is read live and displayed before execution; the tool does not hardcode the fee.
