Blockchains like Ethereum, Arbitrum, and Solana operate as separate, independent networks, each with different transaction speeds and costs. Cross-chain bridging lets you move your cryptocurrency from one blockchain to anotherāhelping you access lower fees, new apps, or different protocols when you need them
Bank Transfers Across Countries:
Think of moving your money from a Canadian account to a U.S. account for cheaper remittance or easier spending. Bank transfers often involve payment processors, currency conversions, and extra fees. Bridging lets you do this in crypto, moving your funds from Ethereum (the āCanadian accountā) to Arbitrum or Solana (the āU.S. accountā), usually for much lower fees and quicker access.
Currency Exchange and Remittance:
When you travel, you swap your CAD for USD or EUR, sometimes paying service and exchange fees to get the currency needed locally. Similarly, cross-chain bridging swaps your asset from one blockchain "currency" to another so you can use it for trades or payments where you need it mostāoften saving both time and money along the way.
Property & Registry Transfers:
Transferring a house deed from one province to another can mean paperwork, approvals, and fees. With cross-chain bridging, you're ātransferringā your assetās ownership from one blockchain network to anotherāmaking it usable where conditions (such as transaction fees or access) are better for your needs.
Stock Transfers Across Brokers:
When moving shares from one broker to another for better service or lower fees, you ensure your investments are optimized for your strategy. Bridging in crypto does the sameāmoving assets between networks to capture better DeFi interest rates, trading opportunities, or community tools
No matter your investing strategy, the goal is clear: maximize returns and minimize unnecessary costs. Bridging lets you transact on blockchains where fees are lower and opportunities are greater, whether youāre trading, staking, using decentralized finance apps, or accessing exclusive NFT launches.
Example:
Instead of selling ETH directly on the Ethereum network (with high āgasā fees), you bridge it to Cronos or Arbitrum, where selling is cheaper, keeping more profit in your pocket during a bull market rush.
Most bridges use a ālock-and-mintā system: your asset is securely locked on one blockchain; a matching version appears (āmintedā) on the other. When you want to bring it back, you āburnā the minted version, and the locked asset is released.

While bridging is a great tool, itās not without its challenges:
