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)

CosmWasm

Export default values:

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

export ROLLAPP_HOME_DIR="${HOME}/.rollapp-wasm"
export ROLLAPP_ScETTLEMENT_INIT_DIR_PATH="${ROLLAPP_HOME_DIR}/init"

Setup Dymension network

export HUB_RPC_URL="https://dymension-mainnet-tendermint.public.blastapi.io:443"
export HUB_CHAIN_ID="dymension_1100-1"

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

Initialize RollApp configurations

sh scripts/init.sh

Setup Dymension addresses

Registration

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

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

View address

dymd keys show $PERMISSIONED_KEY --address

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 os

Store address

export SEQUENCER_ADDR=$(dymd keys show sequencer --address --keyring-backend os --keyring-dir "${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 os --broadcast-mode block --fees 1dym -y --node ${HUB_RPC_URL}
