Fluid Io — Frequently Asked Questions

Fluid Io is a next-generation DeFi protocol that makes lending and borrowing digital assets easier, safer, and more capital-efficient. At its core, Fluid Io operates a unified liquidity layer — a shared pool of capital that multiple protocols can tap into simultaneously. This architecture means lenders always earn the best possible yield from all borrowing activity across the ecosystem, without needing to migrate funds between markets. Whether you want to deposit stablecoins for passive yield, borrow against your crypto collateral, or leverage your positions, Fluid Io provides a streamlined one-click experience built on top of Ethereum and EVM-compatible networks.

Earning yield on Fluid Io is straightforward. Connect your Web3 wallet (such as MetaMask or Rabby) to the Fluid Io interface at fluid.io. Navigate to the Lend section and choose an asset you want to supply — options include USDC, USDT, ETH, wstETH, GHO, USDtb, and more. Click "Start Earning," confirm the transaction, and you will immediately begin accruing yield directly in-kind (you receive more of the same token you deposited). There are no lock-up periods and no minimum deposit amounts. Your balance grows every block, and you can withdraw at any time subject to the protocol's automated liquidity constraints.

Fluid Io supports all major EVM-compatible wallets, including MetaMask, Coinbase Wallet, Rabby Wallet, WalletConnect-compatible mobile wallets, and the Avocado smart contract wallet developed by Instadapp. Avocado is particularly recommended for power users of Fluid Io because it abstracts gas fees, enables USDC-based transaction payments, and simplifies interaction across multiple networks. Hardware wallets such as Ledger and Trezor are also supported via MetaMask or direct WalletConnect integration.

Fluid Io currently supports lending for a growing list of assets across its liquidity layer. Supported lending assets include:

• USDC — USD Coin stablecoin, ~4.16% Net APR
• USDT — Tether stablecoin, ~4.27% Net APR
• GHO — Aave-issued stablecoin, ~8.46% Net APR
• USDtb — Ethena stablecoin, ~5.48% Net APR
• wstETH — Wrapped staked Ether, ~2.5% Net APR
• ETH / WETH — Native Ether, ~1.84% Net APR

APRs fluctuate based on market demand and utilisation rates across the Fluid Io unified liquidity layer. New assets are added via governance decisions.

To borrow on Fluid Io, you first need to deposit collateral — accepted assets include ETH, wstETH, and other approved tokens. Once you have supplied collateral, you can borrow against it up to your allowed Loan-to-Value (LTV) ratio. Fluid Io uses a vault-based borrowing system where each vault defines specific collateral and debt pair parameters, including liquidation thresholds, interest rates, and maximum LTV. Borrowers must monitor their health factor to avoid liquidation. Fluid Io's architecture also supports leveraged borrowing via the Multiply feature, allowing users to open leveraged positions in a single transaction.

There are no minimum or maximum limits for supplying funds to the Fluid Io Lending Protocol. Any amount of a supported asset can be deposited at any time. For withdrawals, Fluid Io uses an Automated Debt Ceiling (ADC) mechanism. Withdrawal capacity increases every block through a smooth algorithmic curve, which prevents sudden large outflows that could destabilise the liquidity layer. In practice, users withdrawing normal amounts will never experience any delay. Very large withdrawals during periods of high utilisation may need to be broken into smaller transactions spread across multiple blocks.

The Multiply feature on Fluid Io allows users to open leveraged positions on supported asset pairs in a single transaction. For example, a user can multiply their ETH/wstETH exposure by automatically borrowing stablecoins against their collateral and using those funds to purchase more collateral — all in one click. This is achieved through Fluid Io's integration with on-chain DEX aggregators and its own Fluid DEX liquidity pools. Multiply is designed for experienced DeFi users who understand leverage mechanics and liquidation risk. The feature dramatically reduces the complexity and gas costs normally associated with setting up leveraged DeFi positions manually.

Fluid Io charges no protocol fees for lending (supplying) assets. Lenders keep 100% of the interest generated by borrowers. For borrowers, interest accrues continuously based on the utilisation rate of each asset pool — rates are shown transparently in the interface before opening any position. Swap and trading activity on the Fluid DEX may incur small trading fees that are distributed to liquidity providers. Network gas fees (paid to Ethereum validators) are separate from Fluid Io protocol fees and are required for all on-chain transactions.

Fluid Io is a novel DeFi protocol. Like all decentralised finance applications, it carries inherent risks that users must understand before participating:

• Smart contract risk: Bugs or vulnerabilities in Fluid Io's code could result in loss of funds, even if the protocol has been audited.
• Liquidation risk: Borrowers whose collateral value drops below the liquidation threshold will have their positions liquidated.
• Market risk: Extreme market volatility can affect collateral values and interest rates simultaneously.
• Oracle risk: Fluid Io relies on price oracles; manipulated or delayed price feeds could cause incorrect liquidations.
• Governance risk: Protocol parameter changes via governance could affect your positions.

Fluid Io has undergone multiple independent security audits. A bug bounty programme is available on Immunefi for responsible disclosure.

$FLUID is the native governance and utility token of the Fluid Io protocol. It serves several key functions within the ecosystem:

• Governance: FLUID holders can participate in on-chain governance to vote on protocol upgrades, new collateral types, risk parameters, fee structures, and treasury management via the Instadapp governance forum and Snapshot voting.
• Protocol revenue: A portion of Fluid Io protocol revenue is directed toward FLUID token holders and the DAO treasury.
• Staking & incentives: FLUID may be staked to earn protocol rewards and participate in liquidity mining incentive programmes.

FLUID is listed and tradeable on major DEXs. Governance discussions happen on the Instadapp forum at gov.instadapp.io.

Fluid Io governance is community-driven and operates through multiple layers. To participate, you can hold $FLUID tokens and use them to vote on active proposals on Snapshot (snapshot.org/#/instadapp-gov.eth). Proposals are first discussed on the governance forum at gov.instadapp.io, where community members can propose changes, share feedback, and reach consensus. The Instadapp Atlas platform provides additional tools for governance participants. Active community members who contribute to discussions, write proposals, and engage in governance help shape the future direction of the Fluid Io protocol.

Smart Lend is an advanced lending strategy available on Fluid Io that automatically optimises your yield by allocating your supplied assets across multiple DeFi lending protocols simultaneously. Instead of earning yield from only Fluid Io's internal borrowing demand, Smart Lend can route capital to wherever the highest risk-adjusted rate is available — including Aave, Compound, Spark, and other integrated protocols. The strategy rebalances automatically, so users benefit from the best rates without having to monitor and migrate their funds manually. Smart Lend is ideal for users who want maximum capital efficiency with minimal ongoing management effort.

Fluid Io Lite is a simplified, automated yield strategy built within the Fluid Io ecosystem. It is specifically designed for users who want exposure to ETH staking yields without actively managing positions. Lite runs the longest-standing stETH/ETH leveraged strategy, automatically managing borrow and supply positions to amplify Ethereum staking returns. The strategy diversifies across multiple protocols including Fluid Io, Aave, Spark, and Compound. Lite targets approximately 1.5x multiplied stETH earnings and handles all the complexity in the background — making it ideal for passive investors who want enhanced Ethereum staking yields.

Yes. Fluid Io currently offers in-kind rewards for users who supply USDC and USDT on the Lending Protocol. These rewards are automatically compounded into your supply balance — meaning your USDC balance grows larger over time, inclusive of both base yield and any reward emissions. Additional reward programmes may be introduced for other assets and protocol activities via governance. Check the Fluid Io interface and official social channels for up-to-date information on active incentive programmes.

Fluid Io smart contracts have undergone multiple independent security audits by reputable blockchain security firms. Audit reports are publicly available through the Fluid Io technical documentation at docs.fluid.instadapp.io. In addition to formal audits, Fluid Io operates a bug bounty programme on Immunefi, which incentivises security researchers to responsibly disclose vulnerabilities. Despite these measures, users should understand that no smart contract system can be guaranteed to be 100% free of bugs. Always do your own research and never deposit funds you cannot afford to lose in any DeFi protocol.

Fluid Io is primarily deployed on Ethereum Mainnet, which is the canonical deployment used by the majority of users and liquidity. The protocol is continuously expanding to additional EVM-compatible networks as the ecosystem grows. The Fluid Io interface provides a network selector that allows users to switch between supported chains. Always verify you are connected to the correct network before submitting transactions. Technical documentation and the latest deployment addresses are available at docs.fluid.instadapp.io.

Fluid Io provides two separate documentation resources. For general users, the Fluid Io Guides at fluid.guides.instadapp.io explain how to use all protocol features in plain language with step-by-step tutorials. For developers and technical users, the Fluid Io Technical Docs at docs.fluid.instadapp.io contain smart contract architecture documentation, ABI references, deployment addresses, integration guides, and API documentation. The Fluid Io GitHub repository at github.com/Instadapp contains open-source smart contract code for community review.
