# Bridging

Just as we use bridges to get from one land mass to another, crypto bridges connect different blockchains. In simple terms, a bridge facilitates the transfer of assets from one chain to another since each blockchain is an independent entity. 

For instance, to move assets from the Solana blockchain to the Ethereum chain, you would need a bridge. This is also true for Layer 2 blockchains.

For an example directly relevant to **$PUFF**, if you have been active on the Ethereum chain but want to buy **$PUFF**; you must bridge your funds from Ethereum Mainnet to Mantle Network. **$PUFF** exists primarily on the Mantle chain, which means you have to bridge your assets to the Mantle Layer 2 and then swap that asset to **$PUFF**.
