HOMEbloK

Easy Escrow is a blockchain based trading center controlled by smart contracts. 2 or more parties can enter items to trade into the smart contract and when all terms are met the contract performs and the items are traded.
An escrow is a financial and legal agreement designed to protect Buyers and Sellers in a transaction. For a fee, an independent third party holds payment until everyone fulfills their responsibilities in the transaction.
With an escrow payment, the Seller will only receive the funds when the Buyer has received and accepted the products and/or services that are part of the transaction. However, the Seller knows they will receive payment because Escrow.com is holding the funds on their behalf

Seeking ERC20 Staking Contract Advisor

This work was really enjoyable because of Serhii Tiutiunnyk's professionalism, communication, and technical understanding. I was really impressed by the way you refactored the code in the authentication feature. Your attention to detail and ability to simplify complex logic made the code much more maintainable. Going forward, I'd like to see you take on more complex challenges and continue to grow your skills.
