ERC-20 tokens are non-native cryptocurrencies issued on the Ethereum blockchain. To view the ERC-20 tokens currently supported by Coins.ph, you may refer to this list: Which ERC-20 tokens does Coins.ph support?
ERC-20 tokens utilize Ethereum addresses and transactions use the same Ethereum network as ETH. As such, outgoing ERC-20 withdrawal transactions also require gas fees to process transactions.
The gas fees required are dynamically calculated based on prevailing Ethereum network activity (gas price * gas limit). These fees are eventually passed on to the miners in the network and our platform does not profit from these fees.
