Our verdict on Solid Yield
6.9/10Solid suits crypto-curious users who want a stablecoin savings account and a Visa card in one self-custodial app, and who accept DeFi risk in exchange for a higher variable yield than bank savings. Its main strength is the combination of earning, spending and borrowing with clear mechanics for SoUSD. The main caveat is its small, young footprint: TVL is about $552,000, yields are maximums rather than guarantees, and returns depend on third-party DeFi strategies. Start with a small amount.

What is Solid Yield?
Solid is a self-custodial money app that combines DeFi yield with a neobank-style interface. Users deposit USDC, receive SoUSD, a yield-bearing token, and can spend through a Visa card issued by Rain.
The protocol runs on Fuse and Ethereum and has been tracked since October 2025. Its TVL is around $552,000, down about 5% over the past week, and it has no native token. Two audits are listed for it.
The homepage advertises up to 6% APY on dollars, up to 15% on FUSE and 3% on ETH, up to 5% cashback and $0 monthly fees. These are upper figures and the yield depends on the underlying strategies. The company does not publish team names or full audit details on its homepage.
How Solid Yield works
When a user deposits USDC, Solid mints SoUSD, a token that represents a share of a vault. The vault allocates funds into whitelisted DeFi strategies, such as lending markets and staking, through a set of curated strategies called BoringVaults.
SoUSD is not pegged one-to-one in the usual way. Its exchange rate equals total vault assets divided by total shares, so as the vault earns, each token is worth more than $1 and new depositors receive fewer tokens for the same USDC. The value of the position grows without staking or locking funds.
The app wraps this with a Visa card, bank-style account details and borrowing against savings. Solid says it abstracts bridging and gas, though users still sign transactions and pay gas on minting and redeeming.

Pros and cons
What we like
- Combines yield, a Visa card, bank transfers and borrowing in one self-custodial app.
- No lockups or staking required for SoUSD, with instant withdrawals advertised.
- Free virtual card with no monthly, top-up or maintenance fees, and Apple Pay and Google Pay support.
- Two audits are listed and strategies are described as whitelisted and curated.
- Clear explanation of how the SoUSD exchange rate works.
Watch out for
- TVL is small at about $552,000, so the vaults have a short and thin track record (listed since October 2025).
- Headline rates such as up to 6% APY and up to 5% cashback are maximums and the yield is variable, not guaranteed.
- SoUSD is not a 1:1 pegged stablecoin; its value depends on vault performance and the underlying DeFi strategies.
- Yield comes from third-party DeFi protocols, so smart-contract failures in those strategies can affect holders.
- The card is issued by a separate provider and the FDIC mention relates to a banking partner, so DeFi balances should not be assumed to be insured.
- No native token, team details or audit reports are shown on its homepage, so users must check the audit listings themselves.
Solid Yield fees
Solid advertises $0 monthly fees, no top-up or maintenance fees on the virtual card, and says other fees may apply under the card terms. Users still pay network gas when minting or redeeming SoUSD.
A full fee schedule, including any performance or vault management fee and foreign exchange charges, is not published on the homepage. Users would find these in the card terms, the Risk Disclosure and the in-app screens before depositing.
Is Solid Yield safe?
Solid says it is non-custodial, that users hold the keys via passkeys and that Solid cannot move funds. Two audits are listed in the protocol's tracking data, but the audit firms and reports are not named in its homepage. Yield is generated in third-party DeFi protocols, so smart-contract, strategy and depeg risks apply, and SoUSD value depends on vault performance.
The Solid Card is a Visa credit card issued by Rain, and Solid states it is a financial technology company, not a bank. FDIC coverage is mentioned for funds at its banking partner, subject to FDIC rules, and does not cover DeFi positions. One review page flags the company as potentially associated with higher-risk investments. Check that the service is available and legal where you live, and read the Risk Disclosure.

Who Solid Yield is for
Solid is aimed at people who hold stablecoins and want yield and everyday spending without managing DeFi positions themselves. It also suits users abroad who want dollar account details and a Visa card. It is less suitable for anyone who needs insured, bank-level safety for all their funds or who is uncomfortable with smart-contract risk.
Solid Yield FAQs
What is SoUSD?
SoUSD is a yield-bearing stablecoin token that represents a share in a vault. Its exchange rate is total assets divided by total shares, so each token becomes worth more than $1 as the vault earns.
Where does Solid's yield come from?
Yield comes from a set of curated DeFi strategies called BoringVaults, spread across chains, such as lending markets and staking. Solid says strategies are whitelisted and audited and are chosen on risk, uptime and on-chain performance.
Is Solid self-custodial?
Solid describes itself as non-custodial and says only the user holds the keys, secured by passkeys. Users still sign transactions and pay gas when minting or redeeming SoUSD, and the underlying strategies carry smart-contract risk.
How much can I earn on Solid?
The homepage advertises up to 6% APY on dollars, plus up to 15% on FUSE and 3% on ETH, with a 4.5% figure also shown. These are maximums, and the vault rate moves with strategy performance.
Who issues the Solid card?
The Solid Card is a Visa credit card issued by Rain, and it is separate from the savings and borrowing features. Solid advertises up to 5% cashback, no monthly fees and acceptance wherever Visa is used, with other fees possibly set out in the card terms.
Is my money FDIC insured?
Solid says it is a financial technology company, not a bank, and that banking services come from a partner bank that is a Member FDIC. FDIC coverage applies to funds held at that bank, not to DeFi vault positions.
Can I withdraw at any time?
Solid says there are no lockups or staking requirements for SoUSD and advertises instant withdrawals. Redeeming still requires signing a transaction and paying gas.
