Within the Zippie platform, Pay My Gas is a subscriber-based (i.e. optional) service layer solution to Zippie users. This service allows Zippie to abstract way from users the complexity in gas [link below] estimation by paying the network fee on user’s behalf for ERC20 transactions.
- Gasless Meta Transactions
In practical terms, by opting in to Pay My Gas services, users do not require to hold ETH in their wallet in order to send ERC20 tokens.
Gas refers to the pricing value required to successfully conduct a transaction or execute a contract on the Ethereum blockchain, applied as an execution fee. This gas value is defined in GWEI (1 Ether = 1,000,000,000 Gwei) which is a fractional denomination of ether (ETH) used to cover computation costs on the Ethereum network to process transactions or execute operations within deployed contracts.
The complexity of the execution of these operations by nodes in the network (within the EVM) will determine the gas required. And the cumulative cost of all operations will represent the total gas cost charged. As a rule of thumb, simple token transfers are generally considered less computationally expensive than complex contract operations.
