Substrate Node with Cosmos ABCI pallet

A new FRAME-based Substrate node with Cosmos ABCI.


Documentation for this project is here


Install Rust:

curl https://sh.rustup.rs -sSf | sh

Initialize your Wasm Build environment:


Build Wasm and native code:

cargo build
For building node with selected consensus
- cargo build -Z package-features --package pallet-cosmos-abci --features "std <consensus_pallet_name>" --no-default-features
- cargo build -Z package-features --package runtime --features "std <consensus_pallet_name>" --no-default-features
- cargo build --workspace --features "<consensus_pallet_name>" --no-default-features


Before running substrate node, you should build and start cosmos node. Go to the our fork of the cosmos-sdk, switch to the branch feature/add_nameservice, then just follow instractions.

To run node locally you will need to specify the environment variables for cosmos-abci pallet.

export ABCI_SERVER_URL=tcp://localhost:26658
export ABCI_GENESIS_STATE_PATH=$HOME/.nsd/config/genesis.json
# or
export ABCI_GENESIS_STATE=$(cat $HOME/.nsd/config/genesis.json)

After any updating of the genesis.json file should specify following encironment variable

export ABCI_GENESIS_STATE=$(cat $HOME/.nsd/config/genesis.json)


Pallets tests

To run tests from local use commands:

# pallet-cosmos-abci
cargo test --test cosmos_abci_unit_test
# pallet-abci
cargo test --test abci_integration_test
cargo test --test abci_unit_test

sh integration tests

Follow to the scripts/integration_tests directory

Single Node Development Chain

Purge any existing developer chain state:

rm -rf abci_storage_rocksdb
./target/release/node-template purge-chain --dev

Start a development chain with:

./target/release/node-template --dev

Detailed logs may be shown by running the node with the following environment variables set: RUST_LOG=debug RUST_BACKTRACE=1 cargo run -- --dev.

Run in Docker

First, install Docker and Docker Compose.

Then run the following command to start a single node development chain. Also, sometimes you have to share permission for the .maintain folder in Docker settings.



docker-compose up -d
