Fallback Function
Fallback function is a special type of function in solidity that is called when either condition is met :-
- A non-existing function is called. Example : function fun() is called from within the contract, which was never defined inside the contract’s code.
- It doesn’t take any parameters but must be marked as external and payable
- If ethers are sent without any function data (information regarding which function to invoke)
Unlock the Power of Solidity: Exploring the Essential Keywords for Smart Contract Development
Solidity is a smart contract programming language built solely to develop smart contracts that can be deployed on blockchains. C++ and JavaScript inspired it, an Object Oriented and High-Level language (HLL), that helps developers define the behaviour and rules for a Decentralized Application (Dapp). Smart contract facilitates autonomous, secure, and efficient transaction execution on the blockchain without needing any intermediary (self-executable) and solidity provides the base framework for achieving the same.
It is essential to understand the common keywords used in solidity to solidify your core understanding of the language so in this article, we’ll pin down some prominent keywords that help us develop these smart contracts by embracing the true power of solidity language.
