Cosmos SDK Quickstart

Get a Cosmos SDK chain running on Evolve using Ignite CLI.

Prerequisites

• Go 1.22+
• Ignite CLI

1. Start Local DA

go install github.com/evstack/ev-node/tools/local-da@latest
local-da

Keep this running in a separate terminal.

2. Create a New Chain

ignite scaffold chain mychain --address-prefix mychain
cd mychain

3. Add Evolve

Install the Evolve plugin for Ignite:

ignite app install -g github.com/ignite/apps/evolve

Add Evolve to your chain:

ignite evolve add

This modifies your chain to use ev-abci instead of CometBFT.

4. Build and Initialize

make install

mychaind init mynode --chain-id mychain-1
mychaind keys add mykey --keyring-backend test
mychaind genesis add-genesis-account mykey 1000000000stake --keyring-backend test
mychaind genesis gentx mykey 1000000stake --chain-id mychain-1 --keyring-backend test
mychaind genesis collect-gentxs

5. Start the Chain

mychaind start \
  --evnode.node.aggregator \
  --evnode.da.address http://localhost:7980 \
  --evnode.signer.passphrase secret

You should see blocks being produced:

INF block marked as DA included blockHeight=1
INF block marked as DA included blockHeight=2

6. Interact

In another terminal:

# Check balance
mychaind query bank balances $(mychaind keys show mykey -a --keyring-backend test)

# Send tokens
mychaind tx bank send mykey mychain1... 1000stake --keyring-backend test --chain-id mychain-1 -y

Next Steps

• Integrate ev-abci — Manual integration without Ignite
• Migrate from CometBFT — Migrate an existing chain with state
• Connect to Celestia — Production DA layer
