LI.FI

LI.FI is a crypto bridge and DEX aggregator. It is not Li-Fi, the tech that sends internet data over light. LI.FI gives wallets and apps one API to swap tokens and move them between blockchains, Solana included. When you bridge inside a wallet such as Phantom or MetaMask, LI.FI is often the service that picks the route.

LI.FI does not run a bridge of its own. It compares routes across other bridges, swap apps and solver networks, then picks one. Philipp Zentner and Max Klenk started the company in Berlin in 2021. Its site lists more than 60 chains and over 1,000 partners. In September 2026 it spun out Jumper, its app for everyday users, as a separate company.

How the LI.FI bridge and swap aggregator works

LI.FI works like a flight search engine for tokens. An app asks for a quote, for example "USDC on Ethereum to SOL on Solana". LI.FI checks the bridges and exchanges it is connected to, ranks the routes by price, speed and cost, and returns a transaction for you to sign.

A single route can chain several steps together. LI.FI might swap your token on the source chain, send it across a bridge, then swap again on the other side. The app shows this as one action and LI.FI tracks it until the funds arrive.

On Ethereum and other EVM chains, your transaction goes to a smart contract called the LI.FI Diamond. LI.FI's architecture docs describe it as the main on-chain entry point. The Diamond passes each transaction to a smaller contract, called a facet, built for the chosen bridge, DEX or solver. New bridges are added as new facets. That design is also where the 2024 exploit came from, covered in the safety section below.

Newer parts of the stack skip bridges. With LI.FI Intents, you lock your tokens in a settlement contract and state what you want to receive. Firms called solvers then pay you on the destination chain from their own funds, and collect your locked tokens once delivery is proven.

LI.FI API, SDK and Widget: products for developers

LI.FI sells to developers and gives them three ways to plug in. The API returns quotes and ready-to-sign transactions to any server. The SDK is a code library that does the same job inside a web app. The Widget is a ready-made swap and bridge box that a team can drop into its own site.

Several products sit on top of those three, per the LI.FI website:

• LI.FI Composer bundles multi-step actions, such as swap then deposit into a vault, into one signed transaction. It launched in February 2026 and runs on EVM chains only, per the Composer docs.
• LI.FI Earn lists yield vaults across more than 20 DeFi protocols and uses Composer to deposit into them.
• LI.FI Intents is the solver marketplace described above.
• The Stablecoin API handles routing tuned for stablecoin transfers.
• LI.FI Scan is an explorer for tracking a cross-chain transfer.

LI.FI's August 2026 update added two features. Smart Deposit Addresses turn a complex action into a plain token transfer: you send funds to an address and LI.FI does the swapping or bridging behind it. Smart Slippage sets the slippage tolerance for each trade automatically instead of using one fixed number.

The chain list keeps growing. LI.FI added Injective in July 2026, then Stellar on 15 September 2026 and Circle's Arc network at its mainnet launch on 16 September 2026, according to LI.FI's changelog and X posts.

LI.FI on Solana: supported bridges, DEX aggregators and wallets

LI.FI works on Solana through its API, SDK and Widget. Its Solana docs list 12 bridges and 4 swap aggregators. An app that uses LI.FI for EVM chains can move users to and from Solana with the same code.

For swaps on Solana, LI.FI pulls quotes from Jupiter JUP$0.315+2.7%, DFlow, Titan and OKX. Those four reach DEXs such as Raydium, Orca and Meteora. For bridging, the docs list Mayan Finance, Allbridge, Relay, Across, Near Intents and Chainflip, among others.

Solana support began with Phantom CASH$0.9990.0%, which LI.FI names as its first Solana launch partner. The wider rollout came on 7 August 2024 with Mayan, Circle's CCTP and Jupiter, per LI.FI's launch post. The docs now name Phantom, Backpack, MetaMask, Binance Wallet, Robinhood and Kamino Finance as Solana users of LI.FI.

Recent Solana changes in the LI.FI changelog:

• LI.FI Intents went live on Solana in August 2026, with gasless transactions.
• SDK v4.2.0, released in July 2026, lets apps choose a Solana priority-fee tier.
• Layerswap routes gained support for native SOL and SPL tokens in August 2026.

Some swaps and bridge routes on Solana are gasless. That means the network fee is paid for you, or taken from the token you send, so you need no SOL. One gap remains: Composer, the one-click deposit tool, does not run on Solana.

LI.FI vs Jumper: what the September 2026 spin-out changes

LI.FI is the infrastructure and Jumper is the consumer app built on it. Until September 2026 the same company ran both. On 26 September 2026, LI.FI said on X that Jumper, "originally incubated within LI.FI", is spinning out to become a separate company.

LI.FI said the two firms will work "from opposite ends of the stack". LI.FI stays the routing layer for businesses and Jumper is the app for people. Jumper's spin-out notice, dated 25 September 2026, names Marko Jurina as its CEO. It also says Jumper will raise money by selling a JUMP token on the Legion platform, with no share sale beside it.

For you as a user, little changes day to day. If you want to bridge by hand, you use Jumper or a wallet. If you are building an app, you plug in LI.FI. Jumper still runs on LI.FI: a Jumper vault campaign on Base, launched on 1 October 2026, sent its deposits through LI.FI Composer.

LI.FI fees: what a swap or bridge costs

LI.FI charges a 0.25% service fee on each swap or bridge, according to its fees FAQ. On a $1,000 transfer that is $2.50. The fee is taken from the token you send.

That is rarely the whole cost. The app or wallet you are using can add its own fee on top through LI.FI's integrator fee setting. The underlying bridge or DEX charges its own fee too, and you pay network gas unless the route is gasless. LI.FI says it offers volume discounts to large partners.

The practical point is that the same route can cost different amounts in different wallets. Check the quoted "you receive" amount, since that figure already includes every fee.

Who LI.FI is for

LI.FI is for teams that want swaps and bridging inside their own product without wiring up dozens of bridges. That means wallets, trading apps and payment apps. Since March 2026 it also means AI agents, which got their own LI.FI API. CEO Philipp Zentner said in September 2026 that more than 1,400 enterprises use LI.FI.

LI.FI suits a Solana team best in one case: your users hold funds on other chains and you want those funds to arrive in one step. A Solana-only app that needs plain swaps gains less. LI.FI's Solana swaps come from Jupiter and its peers, and you can plug into those directly without LI.FI's 0.25% fee.

LI.FI is a poor fit if you are a regular user looking for an app. There is no LI.FI app to sign up for. You will meet it through Jumper or through the bridge tab in your wallet.

Is LI.FI safe? Audits, the 2024 exploit and other risks

LI.FI never holds your funds and its code is audited, but it has been hacked twice. The larger hack cost users $11.6 million in July 2024. Using LI.FI also means trusting the bridge it picks for your route.

The July 2024 hack is the main event to know about. On 16 July 2024 an attacker drained USDC, USDT and DAI from 153 wallets on Ethereum and Arbitrum, per LI.FI's incident report. A new facet lacked a check that every other facet had. That let the attacker make the LI.FI contract call any other contract. Decrypt reported that the faulty contract, GasZipFacet, had been live for five days.

Only wallets that had given LI.FI unlimited token approvals lost funds. LI.FI's API, SDK and Widget ask for limited approvals by default, and those users were safe. LI.FI blamed human error in how the facet was deployed and turned it off on all chains. It said it was weighing options, with its investors, to fully repay victims. A bug in its swap feature had already cost users about $600,000 in March 2022, according to Decrypt.

LI.FI's security page now says every contract is audited before it goes live. LI.FI also runs a bug bounty of up to $1 million through Cantina. The public audit log in its code repository runs from February 2024 to late September 2026 and holds roughly 100 entries. Most are reviews of single facets by one researcher, Sujith Somraaj. Cantina and Burra Security did others.

Three risks remain whatever the audit count:

• Each new facet is new code attached to a contract that holds user approvals. The 2024 exploit came from exactly that.
• An aggregator inherits the risk of the bridge it routes you through. If that bridge fails mid-transfer, LI.FI's audits do not help.
• We could not find a statement in LI.FI's docs of who can upgrade the Diamond contract, such as a multisig or timelock. Integrators should ask.

The simple precaution for users is to avoid unlimited approvals and revoke old ones.

LI.FI alternatives: Bungee, Rango, Squid and deBridge

The main alternatives to LI.FI are other bridge aggregators (Bungee, Rango and Squid) and deBridge, which runs its own solver network. They differ less in chain count than in how they execute a transfer.

Bungee, from the Socket team, and Rango work the way LI.FI does. They collect quotes from many bridges, then run the best one. Rango covers many chains outside the EVM world. Squid sends transfers through Axelar's network, which a comparison by Eco rates as stronger for Cosmos chains. deBridge fills orders from its own solvers and does not pool other bridges, a model built for speed. Eco, which wrote that comparison, is itself one of LI.FI's bridge partners.

For a Solana team, the choice often comes down to the route you care about. LI.FI and its peers give you wide coverage from one piece of code. A single bridge gives you one party to vet and no extra fee on top.

Does LI.FI have a token? Funding and team

LI.FI has not announced a token of its own in any source we reviewed. The JUMP token announced in September 2026 belongs to Jumper, the app that was spun out. JUMP is not a LI.FI token.

LI.FI is funded by venture capital. It has raised $51.7 million in total, The Block reported on 11 December 2025. The rounds were:

With the December 2025 raise, LI.FI said it would spend the money on three things: tools for AI agents, tools for stablecoins, and an open market for intents and solvers. All three have since shipped in some form. They are the agentic commerce API, the Stablecoin API and LI.FI Intents.
