ibc-solidity
IBC implementations in Solidity.
IBC compatibility: v4
This is available not only for Ethereum and Hyperledger Besu, but also for Polygon PoS and other blockchains that supports EVM-compatible.
NOTE: This is yet pre-beta non-production-quality software.
Features
- Implementation of ICS
- Implementation of ICS-20
- ERC-20 Token Transfer

Supported Light Client
You can deploy a Light Client that implements the IClient interface to integrate with IBC-Solidity.
Here are some such examples:
IBC relayer support
- 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

For Developers
Unit test
$ make testE2E test
Launch two Hyperledger Besu chains(ethereum-compatible) with the contracts deployed with the following command:
$ make network-e2eAfter launch the chains, execute the following command:
$ make e2e-test
E2E-test with IBC-Relayer

solidity-protobuf
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
