# Overview

Build on Gearbox Protocol. Choose your path based on how you'll integrate.

## Choose Your Path

### [SDK Guide (TypeScript)](https://docs.gearbox.finance/dev/sdk-guide-typescript/sdk-guide)

**Best for:** Frontend developers, bot builders, analytics dashboards

The SDK provides typed access to Gearbox protocol state and operations. It wraps contract calls, handles encoding, and provides cached market data.

* Read market state via `marketRegister`
* Query credit accounts via services
* Build multicalls with helpers
* No Solidity knowledge required

### [Solidity Guide](https://docs.gearbox.finance/dev/solidity-guide/solidity-guide)

**Best for:** Smart contract developers, on-chain integrators, adapter builders

Integrate directly with Gearbox contracts from your Solidity code.

* Discover contracts via AddressProvider
* Call CreditFacade operations
* Build multicalls in Solidity
* Build custom adapters
