Market creation
Permissionless market creation
Bend allows permissionless market creation. You can create isolated markets, each defined by the five key parameters above. Traditional lending platforms often:- Require governance approval to list assets or change parameters
- Use a single lending pool, so risk is shared across the protocol
To list a market on the Bend UI, submit a vault whitelist proposal (including allocation) via the curator application form.
