Gearbox Protocol contracts are deployed across multiple networks. This page lists the core contract addresses for each supported chain.

## Programmatic Discovery

The recommended way to resolve contract addresses at runtime is through the **AddressProvider** contract. Rather than hardcoding addresses, query the AddressProvider to get the latest verified deployment for any protocol component:

```typescript
import { GearboxSDK } from '@gearbox-protocol/sdk';

const sdk = await GearboxSDK.attach({ client, marketConfigurators: [] });

// Resolve any protocol contract by its key
const [address, version] = sdk.addressProvider.mustGetLatest(
  AP_MARKET_COMPRESSOR,
  VERSION_RANGE_310
);
```

See the [SDK setup guide](https://docs.gearbox.finance/developers/gm-start-ts) for full initialization details.

## Notes

- Always prefer the **AddressProvider** for programmatic address resolution. Hardcoded addresses may become stale after protocol upgrades.
- Market-specific contracts (Pools, Credit Managers, Credit Facades) are discoverable through the MarketCompressor once you have the AddressProvider.
- For a complete list of address keys, see the `AP_*` constants exported by the SDK.
