What is gas and why is gas required to send my transaction or token?

Gas is a required transaction fee paid on a blockchain network, like Ethereum, to incentivize miners or validators to process and verify transactions. The amount of gas required to send a transaction is typically minimal but will depend on the network's current state and the transaction complexity.

• Ethereum blockchain - gas fees are paid in Ethereum (ETH)
• Ethereum Layer 2 blockchains, Arbitrum, Base, Optimism - gas fees are paid in Ethereum (ETH)
• Polygon blockchain - gas fees are paid in (POL)
• Solana blockchain - gas fees are paid in (SOL)

To send tokens (like USDT on Ethereum), gas is required at the same address as the token. Gas fees are paid in the network's native token (ETH) and cannot be paid with a token balance (USDT).

Where can I purchase gas?
