Routers
What Is a Router?
Every Proof of Asset oracle (uScribe) has an associated Router contract. Routers expose the same read interface as the underlying uScribe oracle, but serve as a stable integration point that decouples your contract from the oracle's internal verification logic.
Integrating Proof of Asset Oracles and Their Associated Router
When integrating a Proof of Asset Oracle, your smart contract address will be whitelisted on the associated Router. Make sure to integrate the Router address — not the oracle address directly — into your smart contract.
To read data from a Proof of Asset oracle via its router, call the same read functions you would on a uScribe oracle. No additional configuration is required.
If you are building a new integration, always use the router address rather than the uScribe oracle address directly.
For more details on available read functions, refer to the uScribe documentation.
How Routers Work
Routers sit between your smart contract and the uScribe oracle. When you call a read function on a router, it forwards the request to the corresponding uScribe oracle and returns the result. The interface is identical — you can interact with a router exactly as you would with the oracle directly.
Customer Contract --reads from→ Router --reads from→ uScribe Oracle
Router Naming Convention
Router contract names follow this pattern:
ChronicleVAO_<Issuer>_<AssetTicker>_<Role>_<Counter>
| Segment | Description |
|---|---|
ChronicleVAO | Chronicle Verified Asset Oracle prefix |
<Issuer> | The asset issuer or protocol (e.g., Centrifuge) |
<AssetTicker> | The asset identifier |
<Counter> | Incremental version counter |
Example: ChronicleVAO_Centrifuge_ACRDX_Router_1
Proof of Asset Router Addresses
The tables below list the router contracts for each Chronicle Proof of Asset oracle, organized by chain.
