What is Solid USD (soUSD) (SOUSD)?
Solid USD, often referred by its ticker soUSD, is the primary token for the SOLID protocol, a decentralized finance project designed to function as a savings and spending application. The project aims to bridge the gap between complex blockchain mechanics and everyday financial utility by providing a user-friendly, self-custodial experience. At its core, soUSD is a yield-bearing stablecoin. Unlike traditional stablecoins that require active management to generate returns, soUSD is designed to increase in value over time automatically. When users deposit supported assets like USDC into the protocol, they mint soUSD tokens. These tokens represent a share in the protocol's underlying vaults, known as BoringVaults. These vaults are managed through curated DeFi strategies that deploy capital across various lending markets and staking protocols on multiple blockchain networks to capture rewards. A standout feature of the project is its emphasis on accessibility and real-world application. The protocol is designed to be gasless and signature-free, meaning users do not need to manage native network tokens for transaction fees or navigate the technical hurdles typically associated with on-chain interactions. Furthermore, the ecosystem includes the SOLID Card, a Visa-integrated payment solution that allows users to spend their soUSD balance directly at millions of merchants worldwide. This integration allows the accrued yield to be used for everyday purchases through digital wallets like Apple Pay and Google Pay. The project operates as a cross-chain protocol, primarily utilizing the Fuse network architecture while maintaining the ability to operate across different chains without requiring users to manually interact with bridges. Security within the application is managed through biometric authentication, moving away from traditional seed phrase management to offer a more familiar, bank-grade login experience. By combining decentralized storage principles with automated yield generation and direct spending capabilities, Solid USD seeks to provide a comprehensive DeFi stack for users to earn, save, and spend within a single ecosystem.

Solid USD (soUSD) (SOUSD) FAQ
Staking rewards for soUSD are variable, fluctuating based on protocol liquidation events and token emissions. Rewards are typically distributed in both soUSD and the protocol’s governance token. Currently, these rewards must be claimed manually by the user within the protocol interface rather than being automatically compounded.
The Stability Pool is a core component where users deposit soUSD to maintain protocol health. These deposits are used to absorb debt from under-collateralized positions that face liquidation. In return for providing this liquidity, stakers receive the liquidated collateral at a discounted rate, effectively generating yield through these liquidation events.
soUSD is a decentralized, over-collateralized stablecoin. To mint soUSD, users must provide collateral value exceeding the amount of stablecoins generated. The protocol utilizes assets such as LCRO on Cronos or assets on Fuse. To ensure security, the protocol seeks audits from reputable firms like PeckShield or CertiK to mitigate smart contract vulnerabilities.
The SOLID Card is designed to provide real-world utility for soUSD, enabling both online and in-store transactions. There is significant interest regarding its rollout across various regions, including the EU and US. This card integrates decentralized finance with daily spending, allowing users to leverage their digital assets for traditional commerce.
soUSD is a multi-chain token active on ecosystems such as Fuse and Cronos. The protocol is designed to facilitate gasless cross-chain operations, likely utilizing meta-transactions or relayers to simplify the user experience. Users can acquire soUSD through platforms like LBank or decentralized exchanges on the supported networks.
If the value of deposited collateral falls below a specific liquidation ratio, the position may be liquidated. For Stability Pool participants, a portion of their soUSD balance may decrease as it is used to pay off the debt. However, they are compensated with the liquidated collateral at a discount. Users should monitor collateral ratios to avoid losing deposited assets during market volatility.
