Returns the settlement assets Trusset curates for your instance type, plus the decimal bounds enforced on custom assets. Use this to populate a borrow asset selector before calling Deploy Market. A market’s borrow asset is the token lenders deposit, borrowers receive, and all debt is denominated in. It is fixed at deployment and cannot be changed afterwards.

You are not limited to this list. Any ERC-20 with 6 to 18 decimals can be passed as borrowAssetAddress at deployment. The contract is validated on-chain at that point: it must have deployed bytecode and readable decimals() and balanceOf(). Omitting borrowAssetAddress selects USDC.

Token decimals. Every amount you send or receive for this market’s settlement side is a decimal string parsed at this precision.

boolean

Whether the token exposes a faucet on development networks.

boolean

True for USDC, the asset selected when borrowAssetAddress is omitted.

Custom Asset Rejections

When you pass a borrowAssetAddress that fails validation, Deploy Market returns one of:

Code	Cause
`INVALID_BORROW_ASSET`	Not a well-formed Ethereum address
`BORROW_ASSET_NOT_CONTRACT`	No deployed bytecode at the address on the resolved network
`BORROW_ASSET_NOT_ERC20`	`decimals()` or `balanceOf()` could not be read
`BORROW_ASSET_DECIMALS_UNSUPPORTED`	Decimals outside the 6 to 18 range
