Silo (silo)

​

Notes

• Each Silo is an isolated two-asset market — risk from one market cannot spread to others
• collateralOnly = true gives higher LTV but your deposit cannot be lent out to borrowers
• Use SiloRepository.getSilo(assetAddress) to find the Silo contract for any asset
• The SiloRepository address differs on Ethereum and Arbitrum
• All deposit/repay operations require ERC-20 approval
