The transaction fees on RARI Chain are low (practically zero cost) because of its integration with Arbitrum. This integration protects RARI Chain from Ethereum gas spikes.
Note: The only time you'll be impacted by Ethereum's gas price is when/if you bridge ETH to Arbitrum ETH.
Remember that the token on RARI Chain is ETH, not the foundation's $RARI so don't buy $RARI for transactions on RARI Chain.
