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.
