Credit Silos

A Credit Silo enables Zipcode to offer new types of credit lines, and host competing curators.

• Each Silo operates under the zipUSD umbrella
• Each Silo has its own warehouse.
• Each Silo holds its own isolated risk management machinery.

The SiloRegistry is a Timelocked governance contract which admits new curators — and is the EVM counterpart for onboarding a new Miner Curator on Bittensor.

A Credit Warehouse can scale by adding more Silos, or list new product lines with their own isolated default risk.

Solvency is determined by the **SeniorNavAggregator, which reads the USDC backing for outstanding zipUSD, summed across every silo. The read is determined by the Warehouse Safe’s own pool shares.

Silos allow Zipcode to cluster risk profiles, and localize duration risk within those clusters.
