General FAQ

What is Solid?

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.

How does Solid work?

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.

What makes Solid different?

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.

Where does the yield come from?

Yield comes from BoringVaults, a set of curated DeFi strategies deployed across chains. These vaults are asset-, protocol-, and chain-agnostic: for example, USDC can be allocated to lending markets on Aave, Morpho, or Venus, across Ethereum, Base, or Fuse.

BoringVaults optimize yield on a risk-adjusted basis by routing deposits to the most attractive opportunities and reallocating capital when better yields emerge, all while factoring in protocol risk, liquidity, and uptime.

BoringVaults also automate complex strategies you’d struggle to execute manually, such as rotating stablecoins between high-performing lending markets, or managing LP positions to maximize reward emissions and yield.

What is SoUSD?

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.

Vaults FAQ

How does the rebalancing of pools and allocation work?

Each BoringVault maintains a target allocation of pools, selected from a list of whitelisted strategies. The protocol evaluates these pools daily, factoring in risk, yield, and cost-efficiency. Capital is dynamically reallocated from underperforming pools into those delivering stronger risk-adjusted returns.

This automated process ensures your funds are always working in the most efficient way possible, across chains, protocols, and assets.

How are gas costs, bridging fees and other costs handled?

Gas fees and cross-chain costs are managed at the vault level and socialized across all users. The protocol handles bridging and reallocation automatically, ensuring that users don’t face the friction of manual bridging or unexpected fees.

Vault operations are optimized to minimize unnecessary transactions and costs so your capital is always working efficiently without hidden overhead.

Are the contracts audited?

Yes. All Solid contracts are audited regularly and monitored continuously. You can find detailed audit reports, bug bounty info, and other security measures in our documentation.

How does Solid weigh risk vs yield?

Solid is built to deliver secure, sustainable yield. Our vaults follow strict risk management principles to protect your capital:

• Diversified yield sources: We allocate across multiple protocols and chains to minimize exposure to any single risk.

• Battle-tested protocols only: We work exclusively with audited, reputable protocols that have a strong on-chain track record.

• Risk-adjusted strategy: Volatile or unstable yields are weighted less, while stable opportunities receive higher allocation.

• Real-time monitoring: Protocol performance, risk shifts, and market changes are constantly tracked to adjust allocations dynamically so you don’t have to.
