Venus (venus)

​

Notes

• Same interface as Compound V2 (forked codebase)
• Must call enterMarkets on Comptroller before borrowing against any market
• Also supports VAI stablecoin minting (separate contract)
• Return values: 0 = success, non-zero = error code
• BSC-only deployment
• vBNB (vBNB) takes native BNB, so its mint and repayBorrow take no amount: the BNB sent with the call is the amount.

  require(Venus.Comptroller != 0);
}
