Getting MTR for Gas
MTR is required to pay for gas and transaction fees on the Meter blockchain.
Each transfer transaction on Meter requires about 0.0105 MTR and a swap takes around 0.08 to 0.1 MTR. Here are the ways to get MTR if you don't want to use a centralized exchange:
Bridge any assets from other blockchains to Meter through Meter Passport. Each bridge transaction will receive 0.3 MTR in airdrop.
Use Gasless swap in Meter Wallet. It runs a transaction relay service that helps to swap MTRG into MTR without using gas (the service pays the gas for you).
