# Wallet Security

There are 2 main types of cryptocurrency wallets that exchanges and platforms rely on when it comes to storage of assets - **Cold storage wallets** and **Hot storage wallets**\
\
\- **Cold storage wallet** is a solution for storing crypto assets that isn’t connected to the internet. Therefore there is no way to access the funds held there.\
\- **Hot storage wallets**, on the other hand, have a direct connection to the internet and the exchange’s server.

{% hint style="success" %}
The majority of customer digital assets (Bitcoin) are held in our offline **Cold wallet** storage system. Only a small portion of digital assets are held in our online **Hot wallet** when processing transactions.

All incoming and outgoing transfers (deposits/withdrawals) are executed **manually**, once our team checks all transactions for risk scoring, money laundering, suspicious trading activity, and other patterns.
{% endhint %}

We use Multi-signature access (“Multisig”) to provide both security against attacks and tolerance for losing access to a key or facility, eliminating single points of failure. All fund transfers from Cold Storage to Hot Wallets are handled **manually** and require the coordinated actions of multiple employees.

For maximum security and safety of funds, at PrimeXBT, all customer assets are stored in a cold storage wallet. PrimeXBT processes all pending withdrawals once a day, between 12:00 and 14:00 UTC. A withdrawal requested before 12:00 UTC will be processed on the same day. Any withdrawal requested after 12:00 UTC will be processed on the next day.
