Public Chain Mapping
Public chain mapping refers to the process of transferring a cryptocurrency from its original blockchain network to another blockchain network. There are usually two scenarios as follows:
- Mainnet Launch of Projects
Many blockchain projects temporarily issue tokens through Ethereum smart contracts when their mainnets are not yet developed. For example, EOS was initially issued as a token based on the Ethereum ERC20 standard. When the mainnet goes live, in order to convert users' held tokens into project assets truly based on the mainnet, a redemption process is required, which is called public chain mapping. It is similar to how a project team first "rents a house" on Ethereum to issue tokens, and after the mainnet is launched, the "self-built house" is completed. They need to transfer assets from Ethereum to their own mainnet, and mapping is this "moving" process.
- Cross-Chain Interoperability Needs
Some projects create bridging mechanisms to achieve cross-chain interoperability, allowing users to transfer tokens from one blockchain network to another. This typically involves locking the original tokens on the original network and then issuing equivalent tokens on the target network, thus enabling asset interoperability between the two networks.
Public chain mapping generally requires users to complete the process in accordance with specific procedures and regulations:
If tokens are stored on an exchange, some major exchanges may complete the mapping on behalf of users.
If tokens are in a wallet, users may need to register the tokens themselves, send them from the original wallet address to the wallet address of the new platform, or complete the mapping automatically through a specific wallet.
