A mainnet to exchange token swap has higher fees due to the higher transaction fees on the side of the bridge. In this tutorial, we will be transferring mainnet LTO tokens from our web wallet to the MetaMask wallet, and thus the gas fees are paid by the bridge. To counter this the LTO mainnet fees are higher to pay for these gas fees. At present, a transaction from a mainnet to an ERC-20 address costs 100 LTO. Depending on the ETH price and gas fees per transaction these LTO fees might increase or decrease. Prices for BEP-2 may vary as well, since it's a different network.
