How to run a Polygon node

How to run a Polygon node

Prerequisites

• Check the hardware prerequisites;

• Check which type of node you want to run and the disk space required.

Install Erigon​

To set up Erigon quickly, we recommend the following:

• For Linux and MacOS users, use our pre-built binaries;

• For Windows users, build executable binaries natively.

Start Erigon

To execute an Erigon full node on the Polygon mainnet with remote Heimdall using pre-compiled binaries, use the following basic command:

erigon --chain=bor-mainnet --bor.heimdall=https://heimdall-api.polygon.technology

Example of basic configuration​

The command above allows you to run your local Erigon node on the Polygon mainnet. Additionally, you can include several options, as shown in the following example:

erigon \
--chain=bor-mainnet \
--bor.heimdall=https://heimdall-api.polygon.technology \
--datadir=<your_data_dir> \
--prune.mode=minimal \
--http.addr="0.0.0.0" \
--http.api=eth,web3,net,debug,trace,txpool \
--torrent.download.rate=512mb

Flags explanation

• --chain=bor-mainnet and --bor.heimdall=https://heimdall-api.polygon.technologyspecifies specify respctevely the Polygon mainnet and the API endpoint for the Heimdall network; to use Amoy tesnet replace with flags --chain=amoy --bor.heimdall=https://heimdall-api-amoy.polygon.technology.

• --datadir=<your_data_dir> to store Erigon files in a non-default location. Default data directory is ./home/user/.local/share/erigon.

• Erigon is full node by default, use --prune.mode=archive to run a archive node or --prune.mode=minimal (EIP-4444). If you want to change type of node delete the --datadir folder content and restart Erigon with the appropriate flags.

• --http.addr="0.0.0.0" --http.api=eth,web3,net,debug,trace,txpool to use RPC and e.g. be able to connect your wallet.

• --torrent.download.rate=512mb to increase download speed. While the default downloading speed is 128mb, with this flag Erigon will use as much download speed as it can, up to a maximum of 512 megabytes per second. This means it will try to download data as quickly as possible, but it won't exceed the 512 MB/s limit you've set.

To stop your Erigon node you can use the CTRL+C command.

Several other configurations and options are available.
