When you are about to participate in the upcoming NFT sale on the BASE chain, you suddenly remember:

Oh no, you are a professional dog-chasing expert, you have money on Solana, but you don't have a penny on the BASE chain.

What will you do?

Many friends might think of three words: cross-chain bridge.

That's right, this brings us to the well-known aggregator cross-chain bridge @jumperexchange in the industry.

Jumper Exchange supports seamless cross-chain transactions and exchanges across more than 50 chains, and some cross-chain transactions are gas-free.

As long as you choose which coin to exchange from one chain to another coin on another chain, you can complete the cross-chain transaction at super fast speeds!

And the powerful technology behind Jumper Exchange is the LI FI protocol @lifiprotocol.

LI FI is a cross-chain liquidity aggregation protocol that provides developers with API, SDK, and Widget toolkits to help them seamlessly integrate cross-chain functionality into their applications.

🔹 Widget: A few lines of code can embed a cross-chain interface, supporting multiple chains, multiple languages, and wallet compatibility, suitable for DeFi startups or GameFi quick launches.

🔹 API / SDK: Provides complete path planning, contract calls, and custom interfaces, suitable for medium to large protocols, self-hosted wallets, CEX, or fiat entry platforms.

🔹 Glacis & Airlift: Aggregates cross-chain communication protocols like Wormhole and LayerZero, unifying multi-chain token standards, allowing developers to focus on their applications without worrying about underlying complex logic, enabling intelligent scheduling of assets and messages across chains.

Currently, over 400 projects have integrated LI FI, including industry giants like Phantom Wallet, Binance Wallet, MetaMask, Bybit Wallet, and Robinhood Wallet.

According to disclosures on the official website, LI FI has processed over 31 million transactions, with a total cross-chain amount exceeding 22 billion dollars.

In addition to its core aggregation capabilities, LI FI is also building a deeper intent network infrastructure:

• Stablecoin API: Cross-chain stablecoin asset identification and rapid access

• LI FI Solver: Self-developed executor network to ensure efficient path execution

• LI FI Intents System: Modular protocol that allows external participants to bid to complete users' cross-chain intent execution

This means that in the future, LI FI will not just be about 'aggregating liquidity', but more like an order router and intent marketplace matching platform in Web3.

It can be said that LI FI and Jumper Exchange are not only cross-chain tools at the user level but also important milestones in promoting the standardization and generalization of cross-chain interoperability across the entire Web3.
