NewKeepernow takes in an ICS4Wrapper. The ICS4Wrapper may be the IBC Channel Keeper when ICS20 is not used in a middleware stack. The ICS4Wrapper is required for applications wishing to connect middleware to ICS20. - (core) #650 Modify
OnChanOpenTryIBC application module callback to return the negotiated app version. The version passed into theMsgChanOpenTryhas been deprecated and will be ignored by core IBC. - (core) #629 Removes the
GetProofSpecsfrom the ClientState interface. This function was previously unused by core IBC. - (transfer) #517 Separates the ICS 26 callback functions from
AppModuleinto a new typeIBCModulefor ICS 20 transfer. - (modules/core/02-client) #536
GetSelfConsensusStatereturn type changed from bool to error. - (channel) #644 Removes
CounterpartyHopsfunction from the ChannelKeeper. - (testing) #776 Adding helper fn to generate capability name for testing callbacks
- (testing) #892 IBC Mock modules store the scoped keeper and portID within the IBCMockApp. They also maintain reference to the AppModule to update the AppModule’s list of IBC applications it references. Allows for the mock module to be reused as a base application in middleware stacks.
- (channel) #882 The
WriteAcknowledgementAPI now takesexported.Acknowledgementinstead of a byte array - (modules/core/ante) #950 Replaces the channel keeper with the IBC keeper in the IBC
AnteDecoratorin order to execute the entire message and be able to reject redundant messages that are in the same block as the non-redundant messages.
State Machine Breaking
- (transfer) #818 Error acknowledgements returned from Transfer
OnRecvPacketnow include a deterministic ABCI code and error message.
Improvements
- (client) #888 Add
GetTimestampAtHeighttoClientState - (interchain-accounts) #1037 Add a function
InitModuleto the interchain accountsAppModule. This function should be called within the upgrade handler when adding the interchain accounts module to a chain. It should be called in place of InitGenesis (set the consensus version in the version map). - (testing) #942
NewTestChainwill create 4 validators in validator set by default. A new constructor functionNewTestChainWithValSetis provided for test writers who want custom control over the validator set of test chains. - (testing) #904 Add
ParsePacketFromEventsfunction to the testing package. Useful when sending/relaying packets via the testing package. - (testing) #893 Support custom private keys for testing.
- (testing) #810 Additional testing function added to
Endpointtype calledRecvPacketWithResult. Performs the same functionality as the existingRecvPacketfunction but also returns the message result.path.RelayPacketno longer uses the provided acknowledgement argument and instead obtains the acknowledgement via MsgRecvPacket events. - (connection) #721 Simplify connection handshake error messages when unpacking client state.
- (channel) #692 Minimize channel logging by only emitting the packet sequence, source port/channel, destination port/channel upon packet receives, acknowledgements and timeouts.
- #383 Adds helper functions for merging and splitting middleware versions from the underlying app version.
- (modules/core/05-port) #288 Making the 05-port keeper function IsBound public. The IsBound function checks if the provided portID is already binded to a module.
- (client) #724
IsRevisionFormatandIsClientIDFormathave been updated to disallow newlines before the dash used to separate the chainID and revision number, and the client type and client sequence. - (channel) #644 Adds
GetChannelConnectionto the ChannelKeeper. This function returns the connectionID and connection state associated with a channel. - (channel) \647 Reorganizes channel handshake handling to set channel state after IBC application callbacks.
- (interchain-accounts) #1466 Emit event when there is an acknowledgement during
OnRecvPacket.
Features
- #432 Introduce
MockIBCAppstruct to the mock module. Allows the mock module to be reused to perform custom logic on each IBC App interface function. This might be useful when testing out IBC applications written as middleware. - #380 Adding the Interchain Accounts module v1
- #679 New CLI command
query ibc-transfer denom-hash <denom trace>to get the denom hash for a denom trace; this might be useful for debug
Bug Fixes
- (testing) #884 Add and use in simapp a custom ante handler that rejects redundant transactions
- (transfer) #978 Support base denoms with slashes in denom validation
- (client) #941 Classify client states without consensus states as expired
- (channel) #995 Call
packet.GetSequence()rather than passing func inAcknowledgePacketlog output

cosmos-sdk from 0.43 to 0.44.Bug Fixes
- (07-tendermint) #241 Ensure tendermint client state latest height revision number matches chain id revision number.
- (07-tendermint) #234 Use sentinel value for the consensus state root set during a client upgrade. This prevents genesis validation from failing.
- (modules) #223 Use correct Prometheus format for metric labels.
- (06-solomachine) #214 Disable defensive timestamp check in SendPacket for solo machine clients.
- (07-tendermint) #210 Export all consensus metadata on genesis restarts for tendermint clients.
- (core) #200 Fixes incorrect export of IBC identifier sequences. Previously, the next identifier sequence for clients/connections/channels was not set during genesis export. This resulted in the next identifiers being generated on the new chain to reuse old identifiers (the sequences began again from 0).
- (02-client) #192 Fix IBC
query ibc client headercli command. Support historical queries for query header/node-state commands. - (modules/light-clients/06-solomachine) #153 Fix solo machine proof height sequence mismatch bug.
- (modules/light-clients/06-solomachine) #122 Fix solo machine merkle prefix casting bug.
- (modules/light-clients/06-solomachine) #120 Fix solo machine handshake verification bug.
- (modules/light-clients/06-solomachine) #153 fix solo machine connection handshake failure at
ConnectionOpenAck.
API Breaking
- (04-channel) #220 Channel legacy handler functions were removed. Please use the MsgServer functions or directly call the channel keeper’s handshake function.
- (modules) #206 Expose
relayer sdk.AccAddressonOnRecvPacket,OnAcknowledgementPacket,OnTimeoutPacketmodule callbacks to enable incentivization. - (02-client) #181 Remove ‘InitialHeight’ from UpdateClient Proposal. Only copy over latest consensus state from substitute client.
- (06-solomachine) #169 Change FrozenSequence to boolean in solomachine ClientState. The solo machine proto package has been bumped from
v1tov2. - (module/core/02-client) #165 Remove GetFrozenHeight from the ClientState interface.
- (modules) #166 Remove GetHeight from the misbehaviour interface. The
consensus_heightattribute has been removed from Misbehaviour events. - (modules) #162 Remove deprecated Handler types in core IBC and the ICS 20 transfer module.
- (modules/core) #161 Remove Type(), Route(), GetSignBytes() from 02-client, 03-connection, and 04-channel messages.
- (modules) #140 IsFrozen() client state interface changed to Status(). gRPC
ClientStatusroute added. - (modules/core) #109 Remove connection and channel handshake CLI commands.
- (modules) #107 Modify OnRecvPacket callback to return an acknowledgement which indicates if it is successful or not. Callback state changes are discarded for unsuccessful acknowledgements only.
- (modules) #108 All message constructors take the signer as a string to prevent upstream bugs. The
String()function for an SDK Acc Address relies on external context. - (transfer) #275 Remove ‘ChanCloseInit’ function from transfer keeper. ICS20 does not close channels.
State Machine Breaking
- (modules/light-clients/07-tendermint) #99 Enforce maximum chain-id length for tendermint client.
- (modules/light-clients/07-tendermint) #141 Allow a new form of misbehaviour that proves counterparty chain breaks time monotonicity, automatically enforce monotonicity in UpdateClient and freeze client if monotonicity is broken.
- (modules/light-clients/07-tendermint) #141 Freeze the client if there’s a conflicting header submitted for an existing consensus state.
- (modules/core/02-client) #8405 Refactor IBC client update governance proposals to use a substitute client to update a frozen or expired client.
- (modules/core/02-client) #8673 IBC upgrade logic moved to 02-client and an IBC UpgradeProposal is added.
- (modules/core/03-connection) #171 Introduces a new parameter
MaxExpectedTimePerBlockto allow connections to calculate and enforce a block delay that is proportional to time delay set by connection. - (core) #268 Perform a no-op on redundant relay messages. Previous behaviour returned an error. Now no state change will occur and no error will be returned.
Improvements
- (04-channel) #220 Channel handshake events are now emitted with the channel keeper.
- (core/02-client) #205 Add in-place and genesis migrations from SDK v0.42.0 to ibc-go v1.0.0. Solo machine protobuf definitions are migrated from v1 to v2. All solo machine consensus states are pruned. All expired tendermint consensus states are pruned.
- (modules/core) #184 Improve error messages. Uses unique error codes to indicate already relayed packets.
- (07-tendermint) #182 Remove duplicate checks in upgrade logic.
- (modules/core/04-channel) #7949 Standardized channel
Acknowledgementmoved to its own file. Codec registration redundancy removed. - (modules/core/04-channel) #144 Introduced a
packet_data_hexattribute to emit the hex-encoded packet data in events. This allows for raw binary (proto-encoded message) to be sent over events and decoded correctly on relayer. Originalpacket_datais DEPRECATED. All relayers and IBC event consumers are encouraged to switch topacket_data_hexas soon as possible. - (core/04-channel) #197 Introduced a
packet_ack_hexattribute to emit the hex-encoded acknowledgement in events. This allows for raw binary (proto-encoded message) to be sent over events and decoded correctly on relayer. Originalpacket_ackis DEPRECATED. All relayers and IBC event consumers are encouraged to switch topacket_ack_hexas soon as possible. - (modules/light-clients/07-tendermint) #125 Implement efficient iteration of consensus states and pruning of earliest expired consensus state on UpdateClient.
- (modules/light-clients/07-tendermint) #141 Return early in case there’s a duplicate update call to save Gas.
- (modules/core/ante) #235 Introduces a new IBC Antedecorator that will reject transactions that only contain redundant packet messages (and accompany UpdateClient msgs). This will prevent relayers from wasting fees by submitting messages for packets that have already been processed by previous relayer(s). The Antedecorator is only applied on CheckTx and RecheckTx and is therefore optional for each node.
Features
- #198 New CLI command
query ibc-transfer escrow-address <port> <channel id>to get the escrow address for a channel; can be used to then query balance of escrowed tokens
Client Breaking Changes
