Earn. Spend. Save. Seamlessly.
Abstract
SOLIDās SoUSD (solidUSD) is a yield-bearing, non-custodial stablecoin designed for global adoption. It combines embedded yield, cross-chain simplicity, and real-world spendingābridging the best of DeFi and fintech. Built for mass usage, SOLID removes the friction of crypto while preserving its core values: transparency, ownership, and financial freedom.
1. The Problem: Fragmented Finance
DeFi offers yield and transparency, but demands technical knowledge CeFi offers convenience, but hides risk behind black boxes
Neither serves the next billion users
Stablecoins have cracked open the foundation of financeāvalue storage, movement, and growth. Now, the race is on to rebuild the stack. SOLID is designed to win this race.
2. Vision: Solid Is Your Wallet-Native Financial Layer
Wallets are becoming the new banksāand SOLID is building the financial stack to power them.
SOLID isnāt just another stablecoin project. Itās a decentralized bank where users earn, spend, and save through one gasless, smart asset: SoUSD. Designed to operate cross-chain with zero friction, SOLID turns any wallet into a yield-generating financial hubāwithout compromising on custody, speed, or simplicity.
SOLID solves the core problems stablecoins havenāt:
Poor UX and wallet fragmentation
Slow settlement and high fees
Opaque risk and centralized exposure
No native yield or liquidity incentives
What You Can Do with SOLID
Save: Deposit USDC or other stablecoins to mint SoUSD instantly
Earn: SoUSD generates native yield via secure, curated DeFi strategies
Spend: Use your balance in real life with the SOLID Cardāno bridges, no swaps
Experience: A slick interface, gasless by design, with full self-custody
Under the Hood: SolidVaults, Abstraction & Scaling for Real Adoption
1. SolidVaults & Yield Tokens
SOLIDās yield engine is powered by SolidVaultsāa decentralized vault system that mints yield tokens. These tokens represent your ownership stake and separate principal from interest, enabling advanced use cases like fixed yield and leveraged strategies. This structure also improves risk segmentation for users and unlocks new financial opportunities.
2. Diversified Risk Strategies
Each SolidVault curates a mix of top-performing DeFi strategies across multiple chains, optimizing for both yield and risk. By diversifying across strategies and protocols, SOLID aims to offer more consistent and stable returnsāeven in volatile market conditions. This brings real DeFi risk management to a mainstream audience.
3. Abstraction for Simplicity
SOLID removes blockchain friction through account abstraction:
No gas, no complex approvals, no wallet gymnastics.
Just tap, approve, and youāre done.
Itās DeFi that feels like your favorite fintech appāwithout giving up decentralization.
4. ZK-Powered Scale on Fuse
SOLID is built for scale.
Fuseās upcoming ZK stack will serve as our long-term infrastructureābringing instant finality, low fees, and seamless composability. This unlocks global yield and payment rails on a trustless, scalable Layer 2.
5. Governance & Protocol Ownership
SOLID isnāt just yieldāitās community-owned finance.
Depositors earn points and governance rights through their activity, giving them a stake in protocol decisions and future token allocations. Weāre building toward a fully decentralized system, not another bank.
6. Revenue Share & Sustainable Growth
Instead of taking protocol fees for ourselves, 10% of vault revenue will be used for user acquisition and onboarding. This includes gamified incentives and educational missionsādesigned to grow SOLIDās user base sustainably. Itās a growth engine, not a rake.
