What is a Mainnet Swap?

Mainnet Swap is a process that occurs when a cryptocurrency project migrates from a testnet or other blockchain network to its own mainnet. This typically occurs when the project has reached a sufficient level of maturity and is ready to launch as a fully operational cryptocurrency.

The main purpose of a mainnet swap is to provide a more secure and stable platform for the transfer of cryptocurrency assets and the execution of smart contracts. By moving from a testnet to a mainnet, the cryptocurrency can take advantage of the added security and decentralization provided by its own blockchain network.

The mainnet swap process involves several steps, including the creation of a new blockchain, the distribution of coins to existing holders, and the migration of data from the old blockchain to the new one. This process typically involves coordination between the project team, exchanges, and other stakeholders in the cryptocurrency ecosystem.

It's important to note that mainnet swaps can be complex and risky, and it's essential to follow best practices and guidelines to ensure a successful transition. For example, it's important to ensure that all existing users have their assets transferred to the new mainnet and that the new network is fully functional before the old network is shut down.

Overall, mainnet swaps are a critical step in the development of any cryptocurrency project and play a crucial role in establishing the network's security and stability.

Simplified Example

Think of a mainnet swap like trading vehicles with your friends. Imagine you have a car and your friend has an airplane. You both love your vehicles and want to keep them, but you both want to try driving a different vehicle.

This is what happens in a mainnet swap. People who have digital money or tokens on one network (like the car) can exchange them for the same digital money or tokens on another network (like the airplane). Just like trading vehicles with your friend, in a mainnet swap, you can keep using your digital money or tokens, but on a different network that you want to try out.

History of the Term "Mainnet Swap"

The term likely originated around 2017-2018, aligning with the pinnacle of Initial Coin Offering (ICO) activity. During this period, numerous projects raised funds through ICOs and issued ERC-20 tokens on the Ethereum blockchain, representing future utility on the project's forthcoming mainnet, which was still in development. As projects completed the construction of their independent blockchain networks, the necessity emerged to transition from ERC-20 tokens to the project's native tokens on the mainnet, giving rise to the term "Mainnet Swap." Initially circulating within the blockchain community through blogs, forums, and discussions among developers and early adopters, the term gradually gained broader acceptance over time. Now, "Mainnet Swap" is widely recognized within the cryptocurrency space as the concept of mainnet launches and token migrations has become more mainstream.


Ethereum Classic to Ethereum Mainnet Swap: Ethereum Classic is a blockchain network that was created as a result of a hard fork from the Ethereum Mainnet. After the fork, some users chose to continue using Ethereum Classic, while others switched to the Ethereum Mainnet. In a mainnet swap, users who held Ethereum Classic can exchange it for Ethereum on the Ethereum Mainnet.

Binance Smart Chain Mainnet Swap: Binance Smart Chain (BSC) is a high-performance blockchain platform that was created to support decentralized applications and decentralized finance (DeFi) projects. In a mainnet swap, users who held assets on the Ethereum Mainnet can exchange them for equivalent assets on the Binance Smart Chain Mainnet.

TRON Mainnet Swap: TRON is a decentralized blockchain platform for building and running decentralized applications and executing smart contracts. In a mainnet swap, users who held TRON tokens on the Ethereum Mainnet can exchange them for TRON tokens on the TRON Mainnet. This allows users to take advantage of the faster transaction speeds and lower fees that are offered on the TRON Mainnet.

  • Atomic Swap: A decentralized way of exchanging cryptocurrencies or digital assets from one blockchain to another, without the need for a centralized exchange or intermediary.

  • Location Swap: An innovative technology that makes it possible to easily switch between different locations while using a digital device.
