TL;DR
Solana DeFi holds billions in total value locked across trading, lending, and staking, with Jupiter, Kamino, and Raydium among the largest protocols.
What you can do with capital sorts into four moves: trade it, lend it, stake it, or hand it to a yield strategy.
Most of those moves quote in USDC, so what you bridge over decides what you can do on arrival.
Across bridges into Solana from 23+ chains in about 2 seconds, delivering native USDC ready to deploy.
Solana spent years known mostly for speed and cheap transactions. What it has now is an economy. By 2026 Solana DeFi holds billions in total value locked, and the chain's throughput finally has products worth running on it. The useful way to read that economy is not as a list of apps but as a list of things you can do with a dollar once it arrives. There are four. (Not financial advice. DYOR. This is just a blog post, treat it as such!)
Trade It: Jupiter Routes, Raydium Supplies the Liquidity
The first thing most capital does on Solana is move through Jupiter. It began as a DEX aggregator, finding best execution across the chain's many liquidity sources, and grew into Solana's most-used DeFi platform, now spanning swapping, the Jupiter Lend market, and a set of trading products. Underneath the aggregator sit AMMs like Raydium, the chain's largest, including concentrated-liquidity pools that let providers post capital in tight price ranges. Bridge in to trade and Jupiter is usually the first app you touch, with Raydium often the pool you actually fill against.
Lend It: Kamino Holds the Deepest Money Markets
The second move is putting a dollar to work as credit. Kamino holds one of the largest TVL positions in Solana DeFi, running lending markets alongside Jupiter Lend and other venues. Supply USDC and it earns a borrow rate; post collateral and you can borrow against it without selling. This is where capital that isn't being actively traded goes to stop sitting still.
Stake It: Jito and Marinade Make Staked SOL Liquid
The third move applies to SOL rather than dollars. Jito and Marinade issue liquid staking tokens that stay usable across the rest of DeFi while the underlying SOL keeps earning, and Jito additionally captures MEV value for stakers. Those tokens become base collateral elsewhere in the stack, so this layer feeds the lending and yield ones above and below it.
Hand It to a Strategy: Kamino Vaults and Structured Products
The fourth move is delegating the first three. Kamino's automated vaults manage liquidity positions so providers don't rebalance by hand, and structured products fold these primitives into single-click strategies. This is the layer that turns raw liquidity into managed return for people who don't want to manage it themselves.
Why You Want Native USDC When You Land
Notice what runs through all four moves: the unit is USDC. Jupiter routes against it, Kamino's largest markets price in it, most yield is quoted in it. That is why the token you arrive holding decides what you can do on day one. Bridge over the canonical USDC Circle issues on Solana and every move above is open immediately; arrive with a wrapped stand-in and you are stuck converting before you can start.
Across Delivers Native USDC to Solana in Seconds
Across moves assets to Solana from 23+ chains with sub-2-second fills on mainnet. Select your origin chain and token at the Solana bridge route, choose what you want on Solana, and confirm one transaction. A relayer puts the funds on Solana immediately and settles later, so you don't wait on origin-chain finality. Crossing from an EVM chain into Solana's SVM is a real handoff, and the USDC that lands is the canonical token, not a wrapped placeholder.
The protocol has run since 2021 with no protocol-level exploit, so capital you bridge in to chase Solana yield isn't the risky part of the trip.
Solana built the throughput first and the economy second. Both are here now, and the four moves above open the moment your USDC lands. And yes - Across is the best way to move your USDC to Solana!
