Wallet Assignment

Upon creation, the platform assigns a wallet address you control. Users deposit non-permit tokens into this wallet.

3️⃣ Manage Custodial Wallet Balances

💰 Deposit Native Coin

Keep enough of the chain's native coin in the custodial wallet to cover withdrawal fees.

Example: ETH for Ethereum network, BNB for BSC network

📤 User Withdrawals

When users withdraw, the custodial wallet sends tokens and deducts gas fees from its native coin balance.

Process: User requests → Wallet sends tokens → Fees deducted automatically

✅ Best Practices

💰 Maintain Adequate Gas Reserves

Always keep sufficient native coins in custodial wallets to cover user withdrawal fees and operational costs.

🔍 Monitor Wallet Activity

Regularly check custodial wallet balances and transaction history for any unusual activity or issues.

🔒 Implement Security Measures

Use multi-signature wallets and implement withdrawal limits to enhance security for large custodial operations.

📊 Track Fee Costs

Monitor gas fees and adjust your platform's withdrawal fees accordingly to maintain profitability.

🎯 Final Thoughts

Success!

Custodial wallets simplify user experience for tokens that can't pay fees themselves but require the platform to manage private keys and gas costs.
