Coinbase enables $100K loans

Crypto-backed borrowing is basically a way to get cash without selling the coin you already hold. That matters because selling can trigger taxes, kill upside if the asset rallies, and force people out of positions they still want. Coinbase just widened that option again. On May 12, it added Solana as eligible collateral for its onchain USDC loan product, so some U.S. customers can now borrow against SOL directly in the Coinbase app and web flow. ### What actually changed for users? The new thing is simple: SOL joined the list of assets that can back a Coinbase loan. Coinbase already offered this setup for bitcoin, ether, cbETH, XRP, DOGE, ADA, and LTC. The loans are denominated in USDC, and Coinbase acts as the front end while the borrowing itself runs through Morpho on Base. Eligible users are in the U.S. excluding New York, with more limited access in the UK. (help.coinbase.com) ### Is the limit $100,000 or $1 million? This is the first thing that needs clearing up. Coinbase’s own help page now lists a $1 million borrowing limit for SOL. But the news report tied to today’s rollout described the SOL expansion as letting users borrow up to $100,000 against their holdings. The clean read is that $100,000 may describe the initial rollout or a user-facing cap in this launch context, while Coinbase’s broader product documentation shows the higher product-level ceiling. (help.coinbase.com) The key point is that SOL is no longer a tiny test case — it sits in the same serious borrowing stack as Coinbase’s other supported collateral. ### How does this loan actually work? You post crypto as collateral, receive USDC, and keep exposure to the asset as long as the loan stays healthy. There are no credit checks, no fixed repayment deadline, and no monthly payment requirement. But this is not free money. The rate is variable, there’s a one-time processing fee, and if the loan-to-value ratio rises too far, the collateral can be liquidated automatically. Coinbase’s borrow page says liquidation risk kicks in if LTV goes above 86%. (help.coinbase.com) ### Why does Coinbase route this through Morpho? Because Coinbase is pushing a hybrid model — centralized app, onchain rails. Morpho is the lending protocol underneath, and Base is the chain where the loan mechanics live. That lets Coinbase offer a familiar interface without keeping the whole credit product on its own balance sheet the old-fashioned way. It also fits Brian Armstrong’s longer-running pitch that more financial services will move onchain. (help.coinbase.com) ### How big is this business already? Bigger than the “borrow against your crypto” feature might sound at first glance. Coinbase told The Block its crypto-backed loans have passed $2.3 billion in total originations since launch. Bitcoin still dominates that pool at $2.17 billion, with ether far behind at about $110 million. The altcoin book is much smaller so far — XRP, DOGE, ADA, LTC, and cbETH are all tiny next to BTC. That makes SOL the next real test of whether users want to lever large non-Bitcoin holdings through Coinbase’s interface. (help.coinbase.com) ### Why does Solana matter here? Because SOL is one of the few non-Bitcoin assets with enough liquidity, user base, and onchain activity to support a meaningful lending market. Adding it is not just one more ticker. It’s Coinbase saying Solana holders are important enough to get the same “don’t sell, borrow instead” treatment that used to be concentrated in BTC and ETH. If this gains traction, Coinbase gets deeper into credit, stablecoins, and onchain finance all at once. (theblock.co) ### What’s the catch? The catch is that borrowing against volatile collateral works great until the collateral drops fast. A SOL-backed loan can feel like unlocking liquidity, but in a sharp drawdown it behaves more like a margin position with extra steps. That’s why the product is useful and risky at the same time. It gives holders flexibility — but it also pulls more leverage into a market that already moves hard and fast. (help.coinbase.com) ### Bottom line This is really a story about Coinbase turning its exchange into a broader financial app. Adding SOL collateral makes that strategy more credible. The bigger question now is not whether Coinbase can offer crypto-backed loans — it already does at scale — but whether more users start treating their exchange account like a borrow-and-spend account instead of just a place to trade.
