YES, to initiate an action and interact with a smart contract, we will need gas, and not just any gas, but the right fuel! The proper fuel for a blockchain is its COIN, which is the native cryptocurrency of the blockchain.
For Ethereum blockchain, the native coin is Ethereum. So, if we are connected to the Ethereum network through the Metamask wallet, we need Ethereum as fuel in our wallet for virtually all actions: sending a coin or token, interacting with a smart contract from a DeFi protocol, providing liquidity, and more.
For the Binance Smart Chain, the native coin is Binance Coin. Therefore, if we are connected to the Binance Smart Chain network via the Metamask wallet, we need Binance Coin as fuel in our wallet for practically all actions: sending a coin or token, interacting with a smart contract from a DeFi protocol, providing liquidity, and more.
Matic is the native coin of the Matic/Polygon blockchain. If we are connected to the Matic/Polygon network through the Metamask wallet, we need Matic as fuel in our wallet for virtually all actions: sending a coin or token, interacting with a smart contract from a DeFi protocol, providing liquidity, and more.
ATOM is the native coin of the ATOM/COSMOS blockchain. So, if we are connected to the ATOM/COSMOS network via the Keplr wallet, we need ATOM as fuel in our wallet for practically all actions: sending a coin or token, interacting with a smart contract from a DeFi protocol, providing liquidity, and more.
Solana is the native coin of the Solana blockchain. If we are connected to the Solana network via the Sollet wallet, we need Solana as fuel in our wallet for practically all actions: sending a coin or token, interacting with a smart contract from a DeFi protocol, providing liquidity, and more.
