Smart Contacts

Zex’s Smart Contracts form the first core module of our system. Although relatively straightforward in design, these contracts are essential for user interaction, serving as the primary gateway for secure deposits and withdrawals. By leveraging these contracts, Zex ensures that users can seamlessly move assets into and out of the platform while maintaining robust fund management and security.

Vault Contract

The Vault securely holds user funds and processes withdrawals. Upon verifying signatures from the D/W module, it transfers tokens to the designated user. Additionally, the Vault features a specialized permission allowing Zex to withdraw funds under emergency circumstances, ensuring both flexibility and safeguarding of assets.

User Deposit Contract

For each user and on every supported EVM chain, Zex deploys a User Deposit Contract to receive NFTs, ERC20 tokens, and native assets. The Deposit component of the D/W module continuously observes these chains, retrieving deposits data, issuing signature that updating user balances in Zex Core upon validation. Once confirmed, the deposited assets move to the Vault. Notably, the address of each User Deposit Contract remains consistent across all chains, automatically deploying the first time a deposit is detected.

User Deposit Factory

The User Deposit Factory is responsible for deploying each User Deposit Contract at a predetermined address based on a unique user ID. This ensures that every user’s deposit address remains uniform across multiple blockchains. By simplifying and standardizing deployment, the User Deposit Factory plays a crucial role in delivering a seamless cross-chain experience for Zex users.
