# Custodial Wallets Management

Manage user funds for non-permit tokens and UTXO coins

## 📖 Overview

Custodial Wallets store user funds under platform control. These wallets pay transaction fees and handle movements of tokens that don't allow fee delegation or "permit" functionality.

Use Cases

Required for tokens that cannot pay their own transaction fees (non-permit tokens) and UTXO-based cryptocurrencies

## 1️⃣ Open the Custodial Wallets Section

1

### Go to Admin > Extensions > Ecosystem > Custodial Wallets

Navigate to the Custodial Wallets section in the Bicrypto admin panel.

## 2️⃣ Deploy a New Custodial Wallet

1

### Select Blockchain and Create

Choose the blockchain (e.g., Ethereum, Tron, UTXO coin) and click Create/Deploy Custodial Wallet.

2

### 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.
