EVM sentinel callback errors
Functions ¶
func GenerateIsolatedAddress ¶
func GenerateIsolatedAddress(channelID string, sender string) sdk.AccAddress
GenerateIsolatedAddress generates an isolated address for the given channel ID and sender address. This provides a safe address to call the receiver contract address with custom calldata
Types ¶
type AccountKeeper ¶
type AccountKeeper interface {
NewAccountWithAddress(ctx context.Context, addr sdk.AccAddress) sdk.AccountI
SetAccount(ctx context.Context, acc sdk.AccountI)
}
AccountKeeper defines the contract required for account APIs.
type ERC20Keeper ¶
type ERC20Keeper interface {
GetTokenPairID(ctx sdk.Context, token string) []byte
GetTokenPair(ctx sdk.Context, id []byte) (types.TokenPair, bool)
SetAllowance(ctx sdk.Context, erc20 common.Address, owner common.Address, spender common.Address, value *big.Int) error
BalanceOf(ctx sdk.Context, abi abi.ABI, contract, account common.Address) *big.Int
}
type EVMKeeper ¶
type EVMKeeper interface {
CallEVM(ctx sdk.Context, abi abi.ABI, from, contract common.Address, commit bool, gasCap *big.Int, method string, args ...interface{}) (*evmtypes.MsgEthereumTxResponse, error)
CallEVMWithData(ctx sdk.Context, from common.Address, contract *common.Address, data []byte, commit bool, gasCap *big.Int) (*evmtypes.MsgEthereumTxResponse, error)
GetAccountOrEmpty(ctx sdk.Context, addr common.Address) statedb.Account
GetAccount(ctx sdk.Context, addr common.Address) *statedb.Account
}
EVMKeeper defines the expected EVM keeper interface used on erc20
type Unmarshaler ¶
type Unmarshaler struct{}
func (Unmarshaler) UnmarshalPacketData ¶
func (u Unmarshaler) UnmarshalPacketData(ctx sdk.Context, portID, channelID string, data []byte) (any, string, error)
UnmarshalPacketData will unmarshal the packet data for the IBC transfer callback. It expects the data to be in the format of transfertypes.FungibleTokenPacketData. If the data is not in the expected format, it returns an error.
