Gas Pump Custodial Flow

1. You select a blockchain address, you own the PrivateKey, to work as your "Master GP Address".
   • This address will pay for all transfer fees from your "Slave GP Contract Addresses"
2. You Precalculate a "Slave GP Contract Address".
   • The address can be used to deposit assets only.
   • To transfer out requires activating the address (Smart Contract).
3. You assign said precalculated "Slave GP Contract Address" to an End-user to act as a "Deposit address".
4. End-user deposits on-chain assets (ERC-20 tokens) from outside your Exchange or Application to his "Deposit address".
5. You activate the "Slave GP Contract Address".
6. You send the End-user assets to your Master Exchange Address

Observations

  • On-chain cost charged by the blockchain due to Smart Contract Activation.
• The transfer fees from the "Slave GP Contract Address" are paid by your "Master GP Address".
• You avoid Dust management.
