To remain gas and capital-efficient, IPOR Protocol relies on several externally modeled constants:
- leverage cap
- collateral factor
- a dynamic offered rate cap
- base spread params
Those params are not saved to the chain, instead, they are compiled by the off-chain oracle service, signed, and provided via an S3 API. This solution allows to have the params always ready compiled regardless of the computational effort required to prepare them.
The most recent risk params can be found under this URL:
They are valid for 5 minutes from the moment they are published, and publication is done every 60 seconds.
Methods that require risk params to be passed are:
- opening swap
- unwinding swap
- getting offered rate
