Glossary

Key terms used throughout the Gearbox Protocol documentation.

Term	Definition
Adapter	A thin wrapper contract that translates Credit Account multicalls into calls to an external DeFi protocol (e.g., Uniswap, Aave), enforcing collateral checks before and after execution.
Bytecode Repository (BCR)	An on-chain registry of audited contract bytecode. Deployments are verified against the BCR to ensure only approved, audited code runs in production.
Credit Account	An isolated smart-contract account that holds a user's collateral and borrowed funds. All leveraged operations happen inside a Credit Account.
Credit Configurator	The admin-facing contract that governs a Credit Manager's parameters, such as allowed tokens, adapters, debt limits, and liquidation thresholds.
Credit Facade	The user-facing entry point for a Credit Manager. It validates multicalls, enforces health-factor checks, and emits events for account operations.
Credit Manager	The core contract that manages Credit Accounts for a given market. It tracks collateral, debt, and permissions, and delegates user interactions to the Credit Facade.
Credit Suite	The combination of a Credit Manager, its Credit Facade, and its Credit Configurator, together forming the complete management layer for leveraged accounts in a market.
Cross-Chain Multisig (CCM)	A governance mechanism that coordinates administrative actions across multiple chains, ensuring consistent parameter changes for Gearbox deployments on different networks.
Debt Ceiling	The maximum total amount that can be borrowed from a pool by all Credit Managers combined, limiting the pool's overall leverage exposure.
Diesel Token	The ERC-20 LP share token received when depositing into a Gearbox pool. Its value appreciates over time as interest accrues to the pool.
Health Factor	The ratio of a Credit Account's total weighted collateral value to its total debt. A health factor below 1.0 means the account is eligible for liquidation.
Instance	A single deployment of the Gearbox Protocol on a specific chain, consisting of an AddressProvider and all contracts registered through it.
Instance Owner	The governance address (typically a multisig or DAO) that controls an Instance's AddressProvider and can register or update protocol contracts.
Liquidation Threshold (LT)	A per-token coefficient (in basis points) that discounts a collateral token's value when computing the weighted collateral for health-factor calculations. A lower LT means the protocol treats the token more conservatively.
Market Curator	An entity or role responsible for configuring and managing a specific market's parameters, including allowed collaterals, debt limits, and risk settings.
Multicall	A batched sequence of operations executed atomically on a Credit Account within a single transaction. All health-factor checks are deferred until the end of the batch.
Omni-EVM	Gearbox's cross-chain execution model that allows Credit Accounts to interact with protocols on multiple EVM-compatible chains from a single position.
Pool	A lending pool that accepts deposits from liquidity providers and lends to Credit Managers. Each pool is denominated in a single underlying token.
Protocol DAO	The decentralized governance body that oversees the Gearbox Protocol, controlling upgrades, risk parameters, and treasury operations.
Quota	A per-token borrowing allocation within a pool that limits how much of a specific collateral type can be used across all Credit Accounts.
Quota Rate	The additional interest rate (RAY-scaled, per-second) charged on a Credit Account for holding a non-underlying collateral token that requires a quota.
Total Weighted Value (TWV)	The sum of each collateral token's balance multiplied by its price and its liquidation threshold. TWV divided by total debt gives the health factor.
