TL;DR: Users can now swap any token on any chain directly into USX or eUSX on Solstice Finance, in one transaction. Cross-chain deposits are live, powered by LI.FI.

Yield in DeFi has always had a distribution problem.

The strategies exist. Delta-neutral vaults, funding rate arbitrage, hedged staking — institutional-grade returns that don't require you to take directional bets. The infrastructure is maturing. But the access? Still broken.

If you're sitting on ETH on Arbitrum, or USDC on Base, or stables on BNB Chain, and you want to access yield on Solana — you're looking at multiple steps. Bridge to Solana. Swap into the right asset. Deposit into the vault. Each step is a point of friction, a potential failure, and a reason for users to drop off before they ever get to the yield.

That's where LI.FI comes in.

One Swap. Any Chain. Institutional Yield.

Solstice Finance has integrated LI.FI to power cross-chain deposits directly into its protocol. Starting today, users can go from any token on 60+ supported chains to USX or eUSX on Solstice — in a single transaction.

No manual bridging. No intermediate swaps. No chain-hopping. Select your chain, select your token, arrive in yield.

This is what frictionless capital movement looks like when infrastructure actually works together.

What is Solstice?

For those unfamiliar: Solstice Finance is a Solana-native protocol built around USX, a fully collateralized synthetic stablecoin pegged 1:1 to USD and backed by USDC and USDT. It's secured by Chainlink Proof of Reserve for real-time, on-chain verification of its backing.

The real draw is Solstice's YieldVault. Users deposit USX into the vault and receive eUSX — a liquid, yield-bearing token representing their share of the vault's net asset value. The vault runs a multi-strategy, delta-neutral approach: funding rate arbitrage, hedged staking, and tokenized T-bills, dynamically adjusted based on market conditions.

This isn't experimental DeFi yield farming. Its institutional-grade infrastructure, built on Solana, now accessible from everywhere.

Why This Matters

Crypto is a multi-chain world. Liquidity lives across dozens of ecosystems — Ethereum, Arbitrum, Base, Optimism, BNB Chain, Avalanche, Polygon, and beyond. Users shouldn't have to manually navigate the plumbing just to put their capital to work.

Solstice understood this. By integrating LI.FI, they've removed the last major friction point between users and yield. The cross-chain deposit flow is powered by LI.FI's aggregation stack — tapping into the best bridges, DEX aggregators, and solvers across all supported chains to find the optimal route for every transaction.

For users, it means:

• Any token, any chain — Start with whatever you're holding, wherever you're holding it.

• One transaction — No multi-step bridging sequences. No leftover gas tokens on chains you don't use.

• Direct into yield — Land in USX for stability, or go straight to eUSX and start earning immediately.

For Solstice, it means their addressable market just expanded from Solana-native users to the entire cross-chain DeFi ecosystem. That's a meaningful unlock for TVL growth and protocol adoption.

How It Works

The user flow is simple:

1. Go to app.solstice.finance/cross-chain-swap

2. Select your source chain and token

3. Choose USX or eUSX as your destination

4. Confirm the transaction

Behind the scenes, LI.FI's infrastructure handles route optimization — finding the best combination of bridges and swaps to get users from point A to yield, with the best execution on price, speed, and fees.

Building for the Multi-Chain User

This integration is a clean example of what happens when yield infrastructure meets liquidity infrastructure. Solstice built the vault. LI.FI built the pipes. Together, they've turned what was a multi-step, multi-chain process into a single click.

The stablecoin market continues to grow, and yield-native stablecoins are emerging as a category that bridges the gap between passive holding and active earning. Protocols that make it easy to access that yield — regardless of where a user's capital currently sits — are the ones that will capture the next wave of adoption.

Solstice is now one swap away from any chain. Powered by LI.FI.
