Bridge is a service that allows tokens to be converted between networks. NEOPIN currently supports network conversion of NPT, USDT and ETH, and more multi-chain tokens will be supported in the future.

## How it works

NEOPIN Bridge uses the mint-and-burn mechanism, where the original token is locked in the vault and a corresponding amount of the bridged token is minted.&#x20;

***Thus, the value of the bridged token (nToken) is pegged to the value of the original token on a 1:1 ratio.***&#x20;

When the nToken is bridged, the nToken is burned and the corresponding amount of the original token is unlocked and released to the user.
