Our vision
Money, Made Solid
We build financial products that give everyone the power to protect and grow their money - no matter where they were born.
Money should do more than sit still.
Too much of modern money runs on permission. Accounts freeze. Transfers stall. Access depends on where you were born.
Traditional finance was built around institutions. Solid is built around you: one self-custodial place to protect, grow, and spend your money without ever handing over control.
Digital dollars finally make that possible. We built the app that makes it effortless.
No banks deciding who gets access.
No borders limiting opportunity.
No gatekeepers between you and your future.
Foundation
Our story didn't start with Solid.
Solid is built by the team behind Fuse, working on crypto payments for over seven years. Our conviction hasn't changed: the end game isn't institutional chains. It's self-custody, and the closest digital equivalent to cash.
What we believe
Principles that keep us honest.
Technology changes quickly. The things we build for should not.
Access over permission
Financial tools should exist because people need them — not because a gatekeeper approved them.
Simplicity is a feature
Self-custody should feel as natural as the best money apps. No seed-phrase homework.
Transparent by default
Onchain means verifiable. No hidden fees, no fine-print games.
Build on solid foundation
Strong foundations. Simple experience.
Solid brings trusted infrastructure together so the product can feel effortless.

Frequently asked questions
SOLID is a full-stack DeFi protocol that lets users earn, spend, and save directly from their self-custodial wallet. At its core is SoUSD — a yield-bearing, non-custodial stablecoin designed for a seamless, cross-chain experience.
When you deposit USDC, you mint SoUSD — a token that represents shares in a vault optimized for yield. Your funds are allocated into whitelisted, audited DeFi strategies. You earn automatically as the vault grows in value.
No staking. No lockups. Yield compounds passively.
Note: While we abstract gas and signatures for simplicity, you still sign transactions and pay gas when minting or redeeming.
SOLID offers DeFi without the headaches.
You get:
- Real yield from curated strategies
- Abstracted bridging & gas management
- Full control through self-custody
- A sleek interface and upcoming payment card
All in one protocol, designed to just work — for everyone.
SoUSD is a yield-bearing stablecoin. Unlike typical 1:1 pegged stablecoins, SoUSD represents your share in a growing vault.
Its value increases over time as interest accrues — no need to stake or manage positions.
SoUSD is gasless, cross-chain, and composable — ready for use in payments, swaps, lending, and more.
SoUSD uses a dynamic exchange rate, based on the vault's current performance:
exchange rate = total assets / total sharesIf the vault has earned yield, each SoUSD is worth more than $1, so you’ll receive fewer SoUSD tokens — but your USD-equivalent value is preserved and grows over time.
Yield comes from BoringVaults — a set of curated DeFi strategies across chains. Capital is deployed into secure, audited protocols with strong performance histories (e.g., lending markets, staking).
Strategies are selected based on risk, uptime, and on-chain performance, ensuring your SoUSD earns reliable, risk-adjusted yield — without you lifting a finger.
