This video continues exploring DeFi by focusing on cross-rollup bridges and on-ramps. Cross-rollup crypto bridges enable the transfer of assets between different layer twos, while on-ramps convert fiat to cryptocurrency using bank transfers or credit cards, serving as gateways from web2 to web3. Examples of on-ramps on StarkNet include Ramp, Banxa, XBank, and OKX. Cross-rollup bridges like Rofi, Orbiter, and LayerSwap enhance interoperability, boost liquidity, reduce transaction fees, and offer better user experience across chains, but involve added trust assumptions.
The video walks through using Rhino bridge for asset transfer by specifying the amount, origin, destination, and approving the transaction in the connected wallet.
