Cardano IBC Incubator

This project is working towards a bridge implementation to allow exchange of information from a Cardano blockchain to Cosmos SDK based blockchains.

It follows the inter-blockchain communication protocol and is trying to achieve full compliance with the parts of the specification identified necessary for the developed framework.

Caution

Disclaimer

Please be aware that this is an incubator project and by this means it is neither complete nor sufficiently tested at the current point in time to be used for production grade operation of a bridge. So the use of the source code and software artifacts in this repository are subject to your own discretion and risk.

❗ The software withing this repository is provided to you on an "as is" and "as available" basis.

While we strive for high functionality and user satisfaction and endeavour to maintain reliability and accuracy, unforeseen issues may arise due to the experimental nature of this project.

👀 Overview

This repository is divided into four main directories:

• cardano: Contains all Cardano related source code that are part of the bridge as well as some facilities for bringing up a local Cardano blockchain for test and development purposes. It also contains the Aiken based Tendermint Light Client and IBC primitives implementation.
• cosmos: Contains all Cosmos SDK related source code including the Cardano light client (or thin client) implementation running on the Cosmos chain. The folder was scaffolded via Ignite CLI with Cosmos SDK 0.50.
• relayer: Contains all relayer related source code. Forked from https:/cosmos/relayer
• caribic: A command-line tool responsible for starting and stopping all services, as well as providing a simple interface for users to interact with and configure the bridge services.

🚀 Getting Started

Prerequisites

The following components are required to run the project:

• Docker
• Aiken
• deno
• jq
• golang
• Rust & Cargo

Verify Prerequisites

To check if you have all the necessary prerequisites installed:

cd caribic
cargo run check

Running the Services

To start the services:

cd caribic
cargo run start

Stopping the services

To stop the services:

cd caribic
cargo run stop

Using the faucet to create and fund accounts in the test environment

Sidechain:

curl -X POST "http://localhost:4500/" -H  "accept: application/json" -H  "Content-Type: application/json" -d "{  \"address\": \"cosmos1ycel53a5d9xk89q3vdr7vm839t2vwl08pl6zk6\",  \"coins\": [    \"10token\",\"10stake\"  ]}"

or access to http://localhost:4500

To seed the Cardano addresses, you can use the config.json file generated by caribic. This file will be created the first time you run caribic. By default, it can be found at <USER_HOME>/.caribic/config.json.

Sending tokens from Cosmos to Cardano and vice versa

docker exec -it relayer sh # Access to relayer container
cd /root && ./scripts/xtransfer.sh # Start submit transfer packet

After running xtransfer.sh, the relayer will capture the packet, relay a message to Cardano, call Ack on Cosmos, and by that complete the cycle.

You can query balance using this endpoint:

Cosmos:

http://localhost:1317/cosmos/bank/v1beta1/balances/cosmos1ycel53a5d9xk89q3vdr7vm839t2vwl08pl6zk6

Notice that you will have voucher token with prefix: "ibc/" Example:

{
  "balances": [
    {
      "denom": "ibc/018463FA736C852FA78B23CE6CAE123B9182D18658E0F323B130BB4B1FBB6A52",

    }
  ]
}

Notice that you will have UTXO, asset with amount 2000: Example:

Register a new stake pool on the local Cardano blockchain

cd cardano/chains && ./regis-spo.sh <name>

Example:

cd cardano/chains && ./regis-spo.sh alice

Retire a stake pool on the local Cardano blockchain

This will sent a tx to retire your pool in the next epoch:

cd cardano/chains && ./deregis-spo.sh <name>

Example:

cd cardano/chains && ./deregis-spo.sh alice

Register a validator on Cosmos

This script will connect to your current docker and regis a new validator

Run this to check we only have 1 validator: curl -X GET "http://localhost:1317/cosmos/base/tendermint/v1beta1/validatorsets/latest" -H  "accept: application/json"

Run this to regis new validator: cd cosmos/scripts/ && ./regis-spo.sh

Run this to check we now have 2 validators: curl -X GET "http://localhost:1317/cosmos/base/tendermint/v1beta1/validatorsets/latest" -H  "accept: application/json"

Unregister a validator on Cosmos

Stop the running script above, then wait for about 100 blocks (~2 mins), then check we only have 1 validator:

curl -X GET "http://localhost:1317/cosmos/base/tendermint/v1beta1/validatorsets/latest" -H  "accept: application/json"

Test timeout packet

After successful create clients, connections, channels, terminate that terminal(A).

Access this url to check current balance in Cardano: http://localhost:1442/matches/addr_test1vqj82u9chf7uwf0flum7jatms9ytf4dpyk2cakkzl4zp0wqgsqnql?unspent&order=most_recent_first

Access this url to check current balance in Cosmos: http://localhost:1317/cosmos/bank/v1beta1/balances/cosmos1ycel53a5d9xk89q3vdr7vm839t2vwl08pl6zk6

Update script /scripts/xtransfer.sh, timeout-time-offset from 1h to 10s

Open another terminal(B) and run:

docker exec -it relayer sh
cd /root && ./scripts/xtransfer.sh

Recheck you current balance, notice that your balance will be deduct.

Access this url to check current balance in Cardano: http://localhost:1442/matches/addr_test1vqj82u9chf7uwf0flum7jatms9ytf4dpyk2cakkzl4zp0wqgsqnql?unspent&order=most_recent_first

Access this url to check current balance in Cosmos: http://localhost:1317/cosmos/bank/v1beta1/balances/cosmos1ycel53a5d9xk89q3vdr7vm839t2vwl08pl6zk6

In the terminal A, run this to execute timeout

cd /root && ./bin/rly start demo --processor legacy

After seeing something like /ibc.core.channel.v1.MsgTimeout, recheck you current balance, notice that your token will be return back.

Test Crosschain Swap

Prerequisite:

• cargo run start has been finished successfully.

1. Run:

chains/osmosis/osmosis/scripts/setup_crosschain_swaps.sh

to transfer Cardano mock token to Osmosis via IBC, create swap pool with this token and deploy contracts relates to crosschain swap.

2. Copy address of crosschain_swaps contract in result of the previous command to variable CROSSCHAIN_SWAPS_ADDRESS of file swap.sh.

3. Run:

swap.sh

This command will send mock token in Cardano to Osmosis via IBC Packet Forward Middleware, swap this token to uosmo on created pool and send swapped token back to Cardano via Packet Forward Middleware again.
