# Deposit Assets to Mezo

> Guide to depositing your Bitcoin and supported assets into Mezo for self-service Bitcoin banking.

Deposit native Bitcoin or supported ERC-20 tokens (Bitcoin wrappers) to Mezo Mainnet to start earning, borrowing, and trading.

## Before You Begin

<Warning>
  All transactions on Mezo Mainnet are paid using native BTC or tBTC deposits. Before using the network, fund your account with BTC or tBTC to ensure you have gas to pay for transactions.
</Warning>

**Prerequisites:**

* A [Mezo account](/getting-started/creating-an-account) created and signed in
* Your wallet [connected to the Mezo network](/getting-started/connect-wallet)
* Bitcoin or supported ERC-20 tokens to deposit

**Check supported assets:**

You can confirm the token addresses for supported assets on the [Contracts Reference](/resources/contracts#mainnet-asset-token-contracts) page.

    <Warning>
      Always verify the deposit address is correct before sending assets. Sending to an incorrect address may result in permanent loss of funds.
    </Warning>
  </Step>

  <Step title="Confirm Transaction">
    If the transaction is acceptable, confirm the transaction in your wallet
  </Step>
</Steps>

## After Depositing

After the transaction is confirmed on the source network, the bridging process begins. The process can take several minutes to complete before you receive your assets on Mainnet.

**What happens during bridging:**

1. Your transaction is confirmed on the source blockchain
2. The bridge validators verify the transaction
3. Assets are minted or released on Mezo Mainnet
4. Assets appear in your Mezo account balance

<Note>
  Bridging times vary depending on network congestion and the asset being bridged. Bitcoin deposits typically require multiple confirmations before processing.
</Note>

## Supported Assets

Mezo supports:

* **Native Bitcoin (BTC)**: The primary asset for the Mezo network
* **tBTC**: The most battle-tested decentralized Bitcoin bridge with 24k+ BTC bridged since 2020
* **Wrapped Bitcoin tokens**: Various ERC-20 Bitcoin wrappers (check the Contracts Reference for the full list)

## Transaction Fees

**Gas fees on Mezo:**

* All transactions are paid in BTC (18 decimals)
* Ensure you have sufficient BTC for gas before performing operations on Mezo

**Bridging fees:**

* Bridge fees vary depending on the source network and asset
* Fees are displayed in the review screen before confirming your deposit
