Coinbase offers $100K SOL loans

Crypto-backed loans are back at Coinbase, but in a different form than the old “borrow cash against Bitcoin” product. The new version runs through Morpho, an onchain lending protocol on Base, and as of May 12 Coinbase says customers can now post Solana as collateral too. That means a U.S. user can lock up SOL inside the Coinbase flow and pull out USDC instead of selling. The pitch is simple — get liquidity, keep your upside if SOL rises, and avoid triggering a taxable sale in the process. ### What actually changed for SOL holders? Before this update, Coinbase’s current crypto-backed loan push was centered on bigger assets, especially Bitcoin and then Ethereum. The May 12 expansion added SOL alongside ADA, XRP, LTC, and DOGE, each with a lower borrowing ceiling than BTC or ETH. For Solana holders, the practical change is that Coinbase now gives them a mainstream app-based way to turn SOL into borrowing power without moving to a separate DeFi interface first.

That is well below the $5 million cap for Bitcoin-backed loans and the $1 million cap for Ethereum-backed loans, which tells you how Coinbase is ranking collateral quality and risk. The company’s help pages also say the overall loan limit shown to a user depends on the app’s borrowing limits and the collateral available in the account. (coinbase.com) ### Is Coinbase the lender here? Not exactly. Coinbase is the interface, but the borrowing is enabled by Morpho on Base. In plain English, Coinbase is wrapping an onchain lending protocol in a familiar consumer app, so users get a simpler experience while the loan itself is still tied to crypto collateral posted onchain. That structure matters because it is not just “Coinbase restarted lending” — it is Coinbase steering retail users into protocol-based credit rails it does not fully own. (coinbase.com) ### Why would someone do this instead of selling? Because selling SOL ends the bet. Borrowing against SOL keeps the position alive. If someone needs cash for taxes, bills, or a new trade, a USDC loan lets them raise funds while still participating if SOL rallies later. Coinbase leans hard into that use case in its product language — borrow for expenses without selling your crypto. But the flip side is obvious: if SOL falls, the loan gets riskier. (coinbase.com) ### Where does the risk show up? In the loan-to-value ratio. Coinbase’s help docs explain that LTV rises when collateral drops or interest accrues, and high LTV increases liquidation risk. Coinbase also offers “liquidation protection,” which can automatically top up collateral once a threshold is hit, but that only helps if the user already has more of the same asset sitting in the account. A volatile token like SOL can move fast enough that this is not a theoretical problem. (coinbase.com) ### Why does this matter beyond one product? Basically, Coinbase is widening the bridge between exchange accounts and DeFi-style borrowing. That does two things at once. It makes onchain credit feel normal for regular users, and it turns more crypto assets into collateral that can support leverage, spending, or tax deferral strategies. For Solana specifically, it adds one more centralized access point that could increase borrowing activity around the token even though the loan itself lives on Base, not Solana.

It is Coinbase extending a broader idea — your crypto balance should act more like a margin account than a static wallet. The convenience is real. So is the risk. If SOL goes up, borrowers keep the upside. If SOL drops hard, the “don’t sell” strategy can turn into forced selling anyway. (coinbase.com)
