SDK FAQ

The Drift SDK uses BigNum (BN), using this package, to represent numerical values. All numbers in BN are represented as integers, and we will often denote the precision of the number so that it can be converted back down to a regular number.

These available as constants to import from the SDK.

• there is an eventEmitter on the clearingHouse/clearingHouseUser so you can subscribe to the marketAccount and trigger a callback everytime it is updated
  • clearingHouse: https://github.com/drift-labs/protocol-v1/blob/master/sdk/src/clearingHouse.ts#L67
  • clearingHouseUser: https://github.com/drift-labs/protocol-v1/blob/08738da8a80a0c3ff85f28df0f50d1da6d1e35aa/sdk/src/clearingHouseUser.ts#L34

to convert FundingRateRecord . fundingRate to APR %

funding rate is in 10e14, the unit is quote amount (USDC) owned for each single base asset amount to convert to APR % you need to divide by the oracle_twap (1e10) and then multiply 365.25*24

example: so if BTC funding = 6.2 thats 6.2 usdc per BTC 6.2/44000 365.25 24 = % APR

convert 0x1774 to decimal (= 6004)

check idl (clearing_house.json) in repo: https://github.com/drift-labs/protocol-v1/blob/master/sdk/src/idl/clearing_house.json { "code": 6004, "name": "SufficientCollateral", "msg": "Sufficient collateral" }

so the user has sufficient collateral to not be liquidated. its most likely that another liquidator already (partially/fully) liquidated them
