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

You can deploy a Light Client that implements the IClient interface to integrate with IBC-Solidity.

Here are some such examples:

$ make test

Launch two Hyperledger Besu chains(ethereum-compatible) with the contracts deployed with the following command:

$ make network-e2e

After 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
