Types

type Keeper

type Keeper struct {
	// contains filtered or unexported fields
}

Keeper struct

func NewKeeper

func NewKeeper(
	storeKey storetypes.StoreKey,
	cdc codec.BinaryCodec,
	authority sdk.AccAddress,
	ak types.AccountKeeper,
	bk types.BankKeeper,
	ck types.ChannelKeeper,
	tk types.TransferKeeper,
	claimsKeeper types.ClaimsKeeper,
) *Keeper

NewKeeper returns keeper

func (Keeper) GetAppVersion

func (k Keeper) GetAppVersion(ctx sdk.Context, portID, channelID string) (string, bool)

GetAppVersion returns the underlying application version.

func (Keeper) GetIBCDenomDestinationIdentifiers

func (k Keeper) GetIBCDenomDestinationIdentifiers(ctx sdk.Context, denom, sender string) (destinationPort, destinationChannel string, err error)

GetIBCDenomDestinationIdentifiers returns the destination port and channel of the IBC denomination, i.e port and channel on Evmos for the voucher. It returns an error if:

• the denomination is invalid
• the denom trace is not found on the store
• destination port or channel ID are invalid

func (Keeper) GetParams

func (k Keeper) GetParams(ctx sdk.Context) (params types.Params)

GetParams returns the total set of recovery parameters.

func (Keeper) Logger

func (k Keeper) Logger(ctx sdk.Context) log.Logger

Logger returns logger

func (Keeper) OnRecvPacket

func (k Keeper) OnRecvPacket(
	ctx sdk.Context,
	packet channeltypes.Packet,
	ack exported.Acknowledgement,
) exported.Acknowledgement

OnRecvPacket performs an IBC receive callback. It returns the tokens that users transferred to their Cosmos secp256k1 address instead of the Ethereum ethsecp256k1 address. The expected behavior is as follows:

First transfer from authorized source chain:

• sends back IBC tokens which originated from the source chain
• sends over all Evmos native tokens

Second transfer from a different authorized source chain:

• only sends back IBC tokens which originated from the source chain

func (Keeper) Params

func (k Keeper) Params(
	c context.Context,
	_ *types.QueryParamsRequest,
) (*types.QueryParamsResponse, error)

Params returns the module parameters

func (Keeper) SendPacket

func (k Keeper) SendPacket(
	ctx sdk.Context,
	channelCap *capabilitytypes.Capability,
	sourcePort string,
	sourceChannel string,
	timeoutHeight clienttypes.Height,
	timeoutTimestamp uint64,
	data []byte,
) (sequence uint64, err error)

SendPacket implements the ICS4Wrapper interface from the transfer module. It calls the underlying SendPacket function directly to move down the middleware stack.

func (*Keeper) SetICS4Wrapper

func (k *Keeper) SetICS4Wrapper(ics4Wrapper porttypes.ICS4Wrapper)

SetICS4Wrapper sets the ICS4 wrapper to the keeper. It panics if already set

func (Keeper) SetParams

func (k Keeper) SetParams(ctx sdk.Context, params types.Params) error

SetParams sets the recovery params in a single key

func (*Keeper) UpdateParams

func (k *Keeper) UpdateParams(goCtx context.Context, req *types.MsgUpdateParams) (*types.MsgUpdateParamsResponse, error)

UpdateParams implements the gRPC MsgServer interface. When an UpdateParams proposal passes, it updates the module parameters. The update can only be performed if the requested authority is the Cosmos SDK governance module account.

func (Keeper) WriteAcknowledgement

func (k Keeper) WriteAcknowledgement(ctx sdk.Context, channelCap *capabilitytypes.Capability, packet exported.PacketI, ack exported.Acknowledgement) error

WriteAcknowledgement implements the ICS4Wrapper interface from the transfer module. It calls the underlying WriteAcknowledgement function directly to move down the middleware stack.

type Migrator

type Migrator struct {
	// contains filtered or unexported fields
}

Migrator is a struct for handling in-place store migrations.

func NewMigrator

func NewMigrator(keeper Keeper, legacySubspace types.Subspace) Migrator

NewMigrator returns a new Migrator.
