Constants

const BasisPointDivisor uint64 = 10000

BasisPointDivisor used in calculating the MsgMicrotx fee amount to deduct

Variables

View Source 
var AccountId *big.Int = big.NewInt(1)

The ID for the Account token, the only token controlled by a LiquidInfrastructureNFT Note when using this value as an argument, the EVM requires it to be a *big.Int, the non-pointer type will cause execution failure

View Source 
var CurrentNFTVersion *big.Int = big.NewInt(1)
