Setting up transaction rollup node on Ubuntu

proto variable can hold every active protocol, currently 013-PtJakart and 014-PtKathma.

By default, tezos-tx-rollup-node-$proto.service will use:

  • /var/lib/tezos/.tezos-client as the tezos-client data directory, set in DATA_DIR
  • http://localhost:8732 as the tezos-node RPC address, set in NODE_RPC_ENDPOINT
  • 127.0.0.1:8472 as the tezos-tx-rollup-node-$proto RPC address, set in ROLLUP_NODE_RPC_ENDPOINT
  • observer as the tezos-tx-rollup-node-$proto working mode, set in ROLLUP_MODE
  • rollup as the rollup alias, set in ROLLUP_ALIAS

At first you should originate rollup with the provided alias for some implicit account:

sudo -u tezos tezos-client originate tx rollup <ROLLUP_ALIAS> from <IMPLICIT_ACCOUNT_ALIAS>

After that, with the active tezos-node service available with the provided uri, run the following command

systemctl start tezos-tx-rollup-node-$proto.service

In order to change the defaults, open /etc/default/tezos-tx-rollup-node-$proto and modify the variables:

DATA_DIR="/var/lib/tezos/.tezos-client"
NODE_RPC_ENDPOINT="http://localhost:8732"
ROLLUP_NODE_RPC_ENDPOINT="127.0.0.1:8472"
ROLLUP_MODE="operator"
ROLLUP_ALIAS="custom-rollup"

Save and close the editor, restart the service:

sudo systemctl restart tezos-tx-rollup-node-$proto.service
