# System Overview This system operates as a closed structure, accessible only to users who have completed the **KYC** (Know Your Customer) verification process. Both individual users and companies must undergo identity verification. The **KYC** process ensures that users' identities are confirmed, and fraud is prevented. No user can create or cash checks without approval. All transactions take place on a decentralized blockchain-based platform. Security and transparency are guaranteed through smart contracts. These smart contracts automatically and securely execute transactions without the need for manual intervention. Every transaction is recorded on the blockchain, making them traceable and immutable. This structure eliminates the need for a central authority, making transactions faster and more secure. KYC verification ensures that only trusted users can engage in financial activities. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
