🧙‍♂️ This article provides a detailed guide on how to acquire Gas Token on Merlin Chain and explains the usage of various cross-chain bridges.

**Part 1: What is Merlin Chain’s Gas Token?**

Answer: Merlin\_BTC

As a Layer 2 solution for Bitcoin, Merlin Chain generates a 1:1 equivalent of Merlin\_BTC when BTC is bridged into Merlin.

Merlin Chain uses native Bitcoin (Merlin\_BTC) as the gas token to cover transaction fees. Additionally, MERL can currently be used as gas for transactions within the AA wallet. However, Bitcoin has 18 decimal places, which differs from the 8 decimal places used for BTC on the Bitcoin network. This is to ensure consistency with the default decimal precision for tokens on EVM-compatible chains.

Merlin Chain official documentation also provides further details on Gas👇

**Part 2: How to Acquire Merlin\_BTC?**

**1\. Official Cross-Chain Bridge**

This method is suitable for users on the BTC Mainnet. You can obtain Merlin\_BTC by linking a Layer 1 wallet (such as Unisat, OkX Wallet, etc.) and bridging your BTC into the Merlin Chain.

⭐ If you want to bridge Merlin\_BTC back to the BTC Mainnet, you can also use this cross-chain bridge.

**2\. Third-Party Cross-Chain Bridges**

This method is ideal for users on EVM chains, such as those using MetaMask or similar wallets.

You can use third-party cross-chain bridges like [Meson](https://meson.fi/), [Orbiter Finance](https://www.orbiter.finance/en), and others to bridge BTC into the Merlin Chain.

⭐ The AA wallet offers a convenient way to enable fast on-chain and off-chain interactions.

1.  By directly withdrawing MERL from an exchange to your AA wallet address, you can interact on-chain without Merlin\_BTC.
    
2.  Quickly acquire Merlin\_BTC with low transaction fees through the AA wallet

What if you want to use an EVM wallet but don’t have Merlin\_BTC for gas to interact on-chain?

1.  Withdraw MERL from an exchange to your AA wallet address.
    
2.  Use Merlinswap to convert MERL into Merlin\_BTC (using MERL for gas).
    
3.  Transfer Merlin\_BTC to your EVM wallet (using MERL for gas).
