Functions

func BytesToBigInt

func BytesToBigInt(data []byte) *big.Int

func CreateCoinSet

func CreateCoinSet(zrc20address common.Address, amount *big.Int) (sdk.Coins, error)

func GetCosmosAddress

func GetCosmosAddress(bankKeeper bank.Keeper, addr common.Address) (sdk.AccAddress, error)

GetCosmosAddress returns the counterpart cosmos address of the given ethereum address. It checks if the address is empty or blocked by the bank keeper.

func GetEVMCallerAddress

func GetEVMCallerAddress(evm *vm.EVM, contract *vm.Contract) (common.Address, error)

GetEVMCallerAddress returns the caller address. Usually the caller is the contract.CallerAddress, which is the address of the contract that called the precompiled contract. If contract.CallerAddress != evm.Origin is true, it means the call was made through a contract, on which case there is a need to set the caller to the evm.Origin.

func ZRC20ToCosmosDenom

func ZRC20ToCosmosDenom(ZRC20Address common.Address) string

ZRC20ToCosmosDenom returns the cosmos coin address for a given ZRC20 address. This is converted to "zrc20/{ZRC20Address}".
