Choosing Your Path

Adapter Development

Choose this path if you want to:

• Add a new DeFi protocol (DEX, lending, yield) to Gearbox

• Enable Credit Accounts to interact with your protocol

• Become part of the Gearbox ecosystem

Adapters are the bridge between Credit Accounts and external protocols. They enforce security constraints while translating calls to protocol-specific interfaces.

Protocol Integration

Choose this path if you want to:

• Build a smart contract that uses Gearbox Credit Accounts

• Create automated strategies on top of Gearbox

• Compose Gearbox with your own protocol logic

Protocol integrations call Gearbox from the outside, building multicalls and executing operations programmatically.

Core Extension

Choose this path if you want to:

• Extend Gearbox core functionality (CreditManager, Pool, etc.)

• Build custom contract logic that inherits from core contracts

• Implement advanced customizations requiring deep protocol knowledge

This is an advanced path requiring thorough understanding of Gearbox internals, security considerations, and upgrade patterns.

Prerequisites

All paths require:

• Solidity 0.8.x experience

• Understanding of the Multicall System

• Familiarity with Credit Accounts
