Coinbase added Solana (SOL) as accepted collateral on its on-chain lending product on May 12, letting U.S. users outside New York borrow up to $100,000 in USDC against their SOL holdings without selling. The expansion makes SOL the third asset eligible on the non-custodial loan product, joining Bitcoin and Ethereum. Loans run through the Morpho protocol on Base, Coinbase’s Layer 2, with a maximum loan-to-value (LTV) ratio of 70% and rates starting near 5%. The move pushes SOL deeper into traditional credit use cases and signals Coinbase’s continued strategy of routing customer activity through DeFi rails rather than building closed in-house lending books.
A layer 2 blockchain is a separate network built on top of an existing chain that processes transactions faster and cheaper before settling back on the main chain. Coinbase’s Base, where the Morpho loans settle, is a layer 2 built on Ethereum.
Key takeaways
- Coinbase added SOL as collateral on its Morpho-powered onchain loan product, with a 70% max LTV and an 86% liquidation threshold.
- Eligible U.S. users (excluding New York) can borrow up to $100,000 in USDC per loan, with rates starting around 5% and no fixed repayment schedule.
- Coinbase’s onchain loan product has issued more than $2.3 billion in loans since launch, with Bitcoin still the largest collateral class.

Why Coinbase is leaning on Morpho instead of building in-house
Coinbase rolled out Bitcoin-backed loans through Morpho in early 2025, then added Ethereum. SOL is the natural next step given its market cap and the size of the U.S. retail base holding it. The exchange is not running the lending book itself. Morpho is a permissionless lending protocol that lets isolated markets set their own collateral parameters, rates, and oracles, and Coinbase routes user collateral into Morpho vaults on Base.
That design lets Coinbase ship credit products faster than chartered banks can, without taking direct balance-sheet exposure to the loans. It also gives Coinbase a way to keep large SOL holders inside its product surface instead of losing them to off-platform DeFi front-ends. Coinbase confirmed the product has originated more than $2.3 billion in loans across all collateral classes since the Bitcoin launch.
What the terms actually look like
A holder with $10,000 in SOL can draw up to $7,000 in USDC at origination. If the LTV climbs to 86%, the position is auto-liquidated, and a 4.38% penalty is deducted from the liquidated collateral on top of the principal and accrued interest. Borrowers retain ownership of their SOL throughout the loan and can repay at any time with no monthly minimum and no maturity date, which is the standard structure for a Morpho-backed credit line.
The 70% LTV is conservative relative to native DeFi platforms, where SOL collateral often runs at 75% or higher, but it builds in a wider buffer against Solana’s historical price volatility. Interest accrues continuously and is paid in USDC when the borrower repays.
Impact on Solana, DeFi credit, and traditional brokers
The immediate impact for SOL holders is liquidity without a taxable sale. That matters for U.S. users with long-term capital gains exposure, and it gives institutional SOL holders a way to extract working capital while keeping price upside. Solana’s price held above $170 on May 13 as the news circulated, and Solana ETFs took in $26.57 million in net inflows on May 11, their best single day in over two months.
For DeFi credit broadly, this is another sign that retail crypto lending is consolidating onto a small number of permissionless rails, Morpho and Aave, with centralized exchanges acting as the front-end. The collapse of BlockFi, Celsius, and Voyager pulled centralized crypto lenders out of the U.S. market, and the surviving structure puts custody-grade interfaces on top of onchain credit pools.
For traditional brokers, this is also a competitive marker. Charles Schwab opened spot bitcoin and ether trading to retail on May 13 but does not yet offer crypto-backed credit. Coinbase is using DeFi infrastructure to ship a product Schwab cannot match without a banking partner.
What comes next
Expect Coinbase to keep adding collateral types as Morpho markets are spun up on Base. XRP and Cardano are plausible candidates given their U.S. retail volumes, and a stablecoin-collateralized loop is also likely. Watch for the New York exclusion to remain in place until BitLicense holders get explicit guidance on Morpho-backed lending, and watch Solana DeFi TVL for any flow shift if larger SOL holders move collateral from Kamino or marginfi onto Coinbase’s product.
FAQ
How much can users borrow against SOL on Coinbase?
Coinbase caps SOL-backed loans at $100,000 in USDC per borrower, with a 70% maximum loan-to-value ratio. A user with $10,000 in SOL can draw up to $7,000. Liquidation kicks in at an 86% LTV, with a 4.38% penalty on liquidated collateral.
Where is the loan actually processed?
Coinbase routes the collateral into a Morpho vault on Base, its Ethereum Layer 2. Morpho is a permissionless lending protocol that handles the matching of lenders and borrowers, the interest rate curve, and the liquidation logic. Coinbase provides the front-end, identity checks, and USDC payout.
