1. Functional Definition and Technical Scope
The Zelencio On-Chain Withdrawal feature facilitates the secure migration of digital assets from the Zelencio custodial ecosystem to external, decentralized blockchain endpoints (e.g., personal hardware wallets, third-party exchanges, or smart contracts). This protocol executes a "Settlement Event" where the internal ledger balance is debited and a corresponding transaction is broadcasted to the public blockchain.
2. Mandatory Security Gating and Multi-Factor Authentication (MFA)
To ensure the absolute protection of user assets against unauthorized access or device compromise, Zelencio enforces a Sequential Security Stack for every outbound on-chain movement:
2.1. Verified Session Requirement: Withdrawals can only be initiated from an "Authorized Device" recognized by the platform’s security hardware fingerprinting system.
2.2. The Primary Lock (App PIN): The user must successfully input their unique 5-digit security PIN to authorize the withdrawal interface.
2.3. The Hard Lock (2FA): Every withdrawal requires the submission of a time-sensitive, 6-digit code from a linked Google Authenticator (2FA) app.
2.4. Confirmation Notice: Prior to broadcasting, a final "Notice Modal" is displayed, requiring the user to reconfirm the recipient address and the specific network. By clicking "Slide to Confirm," the user acknowledges that they have performed a final audit of the transaction details.
3. Network Compatibility and Chain-Matching Policy
3.1. User Duty of Care:
Zelencio supports a multi-chain environment (including BTC, ERC-20, BEP-20, TRC-20, SOL, and others). It is the User’s Absolute Duty to ensure that the recipient wallet address is compatible with the network selected within the Zelencio interface.
3.2. Warning Systems:
The platform utilizes an "Amber Warning" system that triggers when a user switches networks, alerting them to the risk of asset loss.
3.3. Irreversibility of Blockchain Transactions:
You acknowledge and agree that once an on-chain withdrawal is broadcast to the network, it cannot be cancelled, reversed, or "retrieved" by Zelencio. Assets sent to an incorrect address or via an unsupported network are considered permanently lost.
4. Advanced Fee Management: "Who Pays the Fee?" Protocol
Zelencio provides a transparent and flexible fee-allocation system, allowing users to manage their liquidity with precision:
4.1. Network Fee (Gas): This is the mandatory cost paid to blockchain miners/validators to process the transaction. This fee is determined by real-time network congestion and is not retained by Zelencio.
4.2. Platform Service Fee: Zelencio charges a nominal administrative fee for the technical management and security of the withdrawal broadcast.
4.3. Allocation Options:
Option A (User Pays): The total fee is added to the withdrawal amount and debited from the user's remaining balance.
Option B (Deduct from Amount): The fee is deducted from the principal amount being sent. The receiver will get the "Net Amount" after fees (displayed as "Receive Amount" in green on the UI).
5. Withdrawal Limits and KYC Synchronization
Withdrawal capacity is strictly synced with the user’s Identity Verification (KYC) tier to ensure compliance with global AML standards:
Tier 1: Standard users are limited to a daily withdrawal ceiling of $5,000 USD equivalent.
Tier 2: Verified users are granted a daily limit of $20,000 USD equivalent.
Tier 3: High-volume/Institutional users may withdraw up to $10,000,000 USD daily.
Security Holds: In accordance with our security policy, any change to your account credentials (e.g., changing password or resetting 2FA) will result in an automatic 24-hour withdrawal freeze to prevent potential account takeovers.
6. Anti-Money Laundering (AML) and Address Monitoring
6.1. Transaction Monitoring:
All withdrawal requests are scanned 24/7 by Zelencio’s AI-driven AML monitoring engine.
6.2. Sanctioned Address Blocking:
Zelencio maintains a real-time list of "Prohibited and Sanctioned Wallet Addresses." Withdrawal attempts to addresses associated with illicit activity, mixers, or darknet markets will be automatically blocked, and the account may be placed under investigation in the Security Crypto Account.
7. Transparency and Status Tracking
Real-Time History: Every withdrawal is recorded in the "Transaction History" with an associated Order ID and Transaction Hash (TxID) once broadcast.
Arrival Estimates: Zelencio provides a data-driven "Arrival Estimate" (e.g., "~2 Mins"). However, you acknowledge that these are estimates and actual arrival times depend on third-party blockchain network performance.
8. Limitation of Liability and Non-Refundable Fees
8.1. Network Failure: Zelencio is not responsible for losses caused by blockchain "Forks," network congestion, or bugs within the protocol of a specific cryptocurrency.
8.2. Fee Non-Refundability: Once a withdrawal is authorized and the service fee is debited, the fee is final and non-refundable, even if the external network experiences a delay or the user provides an invalid recipient address.
8.3. External Platform Errors: If you withdraw to another exchange that fails to credit your account due to their internal policies, Zelencio’s responsibility ends at the moment of successful broadcast to the blockchain.
