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
func IsSourceCallbackExecution ¶ added in v0.7.0
IsSourceCallbackExecution returns true when executing inside a source callback.
Types ¶
type AccountKeeper ¶
type AccountKeeper interface {
NewAccountWithAddress(ctx context.Context, addr sdk.AccAddress) sdk.AccountI
SetAccount(ctx context.Context, acc sdk.AccountI)
HasAccount(ctx context.Context, addr sdk.AccAddress) bool
}
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, stateDB *statedb.StateDB, abi abi.ABI, from, contract common.Address, commit bool, callFromPrecompile bool, gasCap *big.Int, method string, args ...interface{}) (*evmtypes.MsgEthereumTxResponse, error)
CallEVMWithData(ctx sdk.Context, stateDB *statedb.StateDB, from common.Address, contract *common.Address, data []byte, commit bool, callFromPrecompile 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
IsContract(ctx sdk.Context, addr common.Address) bool
GetState(ctx sdk.Context, addr common.Address, key common.Hash) common.Hash
GetCode(ctx sdk.Context, codeHash common.Hash) []byte
GetCodeHash(ctx sdk.Context, addr common.Address) common.Hash
ForEachStorage(ctx sdk.Context, addr common.Address, cb func(key common.Hash, value common.Hash) bool)
SetAccount(ctx sdk.Context, addr common.Address, account statedb.Account) error
DeleteState(ctx sdk.Context, addr common.Address, key common.Hash)
SetState(ctx sdk.Context, addr common.Address, key common.Hash, value []byte)
DeleteCode(ctx sdk.Context, codeHash []byte)
SetCode(ctx sdk.Context, codeHash []byte, code []byte)
DeleteAccount(ctx sdk.Context, addr common.Address) error
KVStoreKeys() map[string]storetypes.StoreKey
}
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.
