Set RollApp info defaults

EVM

Export default values:

export KEY_NAME_ROLLAPP="rol-user"
export MONIKER="$ROLLAPP_CHAIN_ID-sequencer"

export ROLLAPP_HOME_DIR="${HOME}/.rollapp_evm"
export ROLLAPP_SETTLEMENT_INIT_DIR_PATH="${ROLLAPP_HOME_DIR}/init"
export EXECUTABLE=$(which rollapp-evm)

Setup Dymension network

export HUB_RPC_URL="https://dymension-testnet-tendermint.public.blastapi.io:443"
export HUB_CHAIN_ID="blumbus_111-1"

dymd config chain-id ${HUB_CHAIN_ID}
dymd config node ${HUB_RPC_URL}
dymd config keyring-backend test

Initialize RollApp configurations

Setup Dymension addresses

Fund the following addresses using Dymension Discord's testnet faucet.

Registration

This address registers the RollApp on Dymension and if applicable may register multiple RollApps.

To get an address whitlisted proceed to the join-language-community channel on Discord. Once there, press the 🏗️ to receive the @Blumbus RollApp Deployer role. Now you have access to the ✅・whitelist-requests-for-rollapp-deployers. Use that channel to post a message containing just the dymension address you’d like to get whitelisted.

Set the key name

export PERMISSIONED_KEY="blumbus-rollapp-whitelisted"
export HUB_PERMISSIONED_KEY="$PERMISSIONED_KEY"
export HUB_KEY_WITH_FUNDS="$PERMISSIONED_KEY"

Create the address

dymd keys add $PERMISSIONED_KEY --keyring-backend=test

View address

dymd keys show $PERMISSIONED_KEY --address --keyring-backend test

Sequencer

This address publishes state updates and operates the RollApp, you don't need to whitelist this address.

Set max amount of sequencers (i.e. 1)

export MAX_SEQUENCERS=1

Create address

dymd keys add sequencer --keyring-dir "${ROLLAPP_HOME_DIR}/sequencer_keys" --keyring-backend test

Store address

export SEQUENCER_ADDR=$(dymd keys show sequencer --address --keyring-backend test --keyring-dir "${ROLLAPP_HOME_DIR}/sequencer_keys")

Fund the sequencer account

If you're using a remote hub node, you must fund the sequencer account or you must have an account with enough funds in your keyring.

# retrieve the minimal bond amount from hub sequencer params
# you have to account for gas fees so it should the final value should be increased
BOND_AMOUNT="$(dymd q sequencer params -o json | jq -r '.params.min_bond.amount')$(dymd q sequencer params -o json | jq -r '.params.min_bond.denom')"

# Extract the numeric part
NUMERIC_PART=$(echo $BOND_AMOUNT | sed 's/adym//')

# Add 100000000000000000000 for fees
NEW_NUMERIC_PART=$(echo "$NUMERIC_PART + 100000000000000000000" | bc)

# Append 'adym' back
TRANSFER_AMOUNT="${NEW_NUMERIC_PART}adym"

dymd tx bank send $HUB_KEY_WITH_FUNDS $SEQUENCER_ADDR ${TRANSFER_AMOUNT} --keyring-backend test --broadcast-mode block --fees 1dym -y --node ${HUB_RPC_URL}
