All these features are helpful when developing smart contracts, so if you’re interested, then we highly recommend checking out Truffle. For example, you can read more about the complete Truffle Suite ecosystem at Moralis’ blog. Furthermore, a smart contract is also a particular type of account on Ethereum’s blockchain. Therefore, just like any other account, they can hold funds and make transactions. However, what differentiates these from traditional accounts is the fact that no user controls them.
Whenever a contract is finalized and settled in Solidity, the code is compiled into EVM’s bytecode. This means that Solidity smart contracts are compatible with other chains utilizing the EVM. As such, we can use Solidity’s programming language for more than Ethereum development since it works on, for example, Binance Smart Chain and Polygon. For this reason, learning Solidity won’t limit you to Ethereum’s ecosystem. Consequently, you can utilize your skills with other chains – as Moralis is a top Infura for BSC and Infura for Avalanche alternative. Solidity is a relatively new statically typed programming language that is synonymous with the Ethereum Virtual Machine , used to create smart contracts.
