What Can You Do with Solidity?
Before looking at Solidity Developers for hire, it is important to know what you can build with Solidity. Some key use cases of Solidity include:
- Voting: It is possible to create voting systems that are automatic, transparent, and immutable with Solidity.
- Safe Remote Purchase: Remotely purchasing goods and services has multiple parties where trust needs to be established. Through the creation of a smart contract with Solidity, the amount for the good is locked until both parties agree to its completion.
- Creating and Verifying Signatures: It is possible to authorize transactions by using verified signatures which have smart contracts on Ethereum.
- Verifying Payments: Through Solidity, verification mechanisms can be created to ensure that payments are redeemed only after they have been proven as valid.
Blockchains that Use Solidity
There are many Blockchains that use Solidity for their businesses. These include Tron, Polygon, Ethereum, Counterparty, Binance Smart Chain, and Avalanche C-Chain.
For instance, the distributed ledger technology company called Hedera Hashgraph has been using Solidity to enable its users to create and execute smart contracts. Their users can create Auctions and DeFi applications with low fees using Solidity.
