# Payment Contract

All payments for purchases and trade of Lands in The Next Earth Project go through the Payment Contract, a specially designed contract written in Solidity. The Payment Contract is not a stand alone contract but a contract system in which different parts handle the different kinds of payments.

\
It handles the payment allocation in a secure, trust-less and fully transparent way. All transactions will be recorded on the blockchain and anyone can check them. During the design of this contract an important key is to keep the transaction's gas fee as low as possible utilizing several smart contract design techniques.<br>
