# Data Oracle (V2 Roadmap)

> Bi-directional financial data oracle, coming in V2.

> [!NOTE]
>
> Coming in V2. Shapes below are a preview.

## Capabilities

**Web2 → Web3 (privacy-preserving inputs):** a Zero-Knowledge TLS oracle streams authenticated bank/account history on-chain without exposing the underlying transaction data. Only a cryptographic proof of financial health is published, e.g. to underwrite an undercollateralized loan.

**Web3 → Web2 (asset aggregation):** an indexer normalizes multi-chain wallet activity (DeFi yields, tokenized RWAs, staked balances) into a clean feed consumable by traditional risk/underwriting systems.

## Preview

```bash theme={null}
curl https://api.openfi.co/v1/oracles/attestations \
  -H "Authorization: Bearer $OPENFI_API_KEY" \
  -d '{
    "account_id": "acc_123",
    "attestation_type": "bank_balance_proof"
  }'
```

See the [Treasury Auto-Rebalancing use case](https://docs.openfi.co/use-cases.md#2-treasury-auto-rebalancing) for where this fits in a full flow.
