IBC implementations in Solidity.
IBC compatibility: v8
This is available not only for Ethereum and Hyperledger Besu, but also for Polygon PoS and other EVM-compatible chains.
DISCLAIMER: This project is still under development and has not been audited.
- Implementation of ICS
- Implementation of ICS-20
- ERC-20 Token Transfer
You can deploy a Light Client that implements the ILightClient interface to integrate with ibc-solidity.
Here are some such examples:
- yui-relayer: An IBC relayer for heterogeneous chains
- ethereum-ibc-relay-chain: A relay-chain module for EVM-compatible chains
- ethereum-ibc-relay-prover: A relay-prover module for Ethereum sync committee
- besu-ibc-relay-prover: A relay-prover module for Hyperledger Besu's QBFT and IBFT 2.0 consensus
- A demo of trustless bridge

- between Celo and Cosmos: https://github.com/ChorusOne/celo-cosmos-bridge

$ make testLaunch two Hyperledger Besu chains(ethereum-compatible) with the contracts deployed with the following command:
$ make network-qbftAfter launch the chains, execute the following command:
$ make e2e-test
An example of E2E with IBC-Relayer(yui-relayer) can be found here:

To generate the proto encoders and decoders in solidity from proto files, you need to use the code generator solidity-protobuf
Currently, v0.1.0 is required.
If you edit the proto definitions, you should execute the following command:
$ make SOLPB_DIR=/path/to/solidity-protobuf proto-sol
