IBC Remote Contract

This a CosmWasm smart contract that demonstrates the Inter-Blockchain Communication protocol capabilities.

This contract does not have any direct user initiated messages. It can only receive messages from the local contract.

Build

Compile and optimize the smart contract Wasm.

make && make optimize

Requirements

• provenanced cli

Workflow

See the Overview for end-to-end steps

This contract is intended to be used with the other two projects in the ibc directory:

• ibc-local
• relayer

To simplify the setup and execution, several scripts are provided in the scripts directory.

1. setup_remote_chain.sh

   The setup_remote_chain script will start a Provenance chain with 3 funded accounts: validator, remoteaccount, and relayer. This "remote" chain will use ports that are slightly modified from default so that the two chains can run simultaneously.

2. store_and_init_remote_contract.sh

   The store_and_init_remote_contract script stores and initializes the "remote" smart contract. This step must be performed before starting the relayer
