# Subgraph Settings

Before deploying subgraphs you need to tweak some things to your needs:

## Algebra

### Constants.ts

[Algebra/src/utils/constants.ts](https://github.com/cryptoalgebra/Algebra_Subgraph/blob/main/Algebra/src/utils/constants.ts)

`FACTORY_ADDRESS` is the address of the AlgebraFactory.sol contract

```
export const FACTORY_ADDRESS = '0x9742E5C4452ccA62ce115d302756e9150CbA36Aa'
```

### Pricing.ts

[Algebra/src/utils/pricing.ts](https://github.com/cryptoalgebra/Algebra_Subgraph/blob/main/Algebra/src/utils/pricing.ts)

`WMatic_ADDRESS` is the address of your network Native Token

```
const WMatic_ADDRESS = '0x0d500b1d8e8ef31e21c99d1db9a6444d3adf1270'
```

`USDC_WMatic_03_POOL` is the address of the Native Token / USDC pair pool

```
const USDC_WMatic_03_POOL = '0xc3c4074fbc2d504fb8ccd28e3ae46914a1ecc5ed'
```

`WHITELIST_TOKENS` is the array of tokens, which many tokens usually are paired with, so we can trust their volume and liquidity

```
export let WHITELIST_TOKENS: string[] = [
  '0x0d500b1d8e8ef31e21c99d1db9a6444d3adf1270', // WMATIC
  '0x2791bca1f2de4661ed88a30c99a7a9449aa84174', // USDC
  '0xc2132d05d31c914a87c6611c10748aeb04b58e8f' // USDT 
]

```

`STABLE_COINS` is the array of stablecoins

```
let STABLE_COINS: string[] = [
  '0x2791bca1f2de4661ed88a30c99a7a9449aa84174', // USDC
  '0xc2132d05d31c914a87c6611c10748aeb04b58e8f' // SUDT
]
```

`MINIMUM_Matic_LOCKED` is the required number of native tokens in the pool to include it when calculating prices

```
let MINIMUM_Matic_LOCKED = BigDecimal.fromString('0')
```

### Subgraph.yaml

[Algebra/subgraph.yaml](https://github.com/cryptoalgebra/Algebra_Subgraph/blob/main/Algebra/subgraph.yaml)

`network` is your network name

```
network: matic
```

For every contract you should change its `startBlock` - the block to sync from, and `address` from your contract deployment

```
 source:
    ...
      address: '0x9742E5C4452ccA62ce115d302756e9150CbA36Aa'
      startBlock: 31656556 
```

## AlgebraFarming

### Constants.ts

[AlgebraFarming/src/utils/constants.ts](https://github.com/cryptoalgebra/Algebra_Subgraph/blob/main/AlgebraFarming/src/utils/constants.ts)

`FarmingCenterAddress` is the FarmingCenter contract address from your contracts deployment

```
export const FarmingCenterAddress = Address.fromString("0xB1d4784473277c162E36656fa066dfEd21B1EC89")
```

### Subgraph.yaml

[AlgebraFarming/subgraph.yaml](https://github.com/cryptoalgebra/Algebra_Subgraph/blob/main/AlgebraFarming/subgraph.yaml)

`network` is your network name

```
network: matic
```

For every contract you should change its `startBlock` - the block to sync from, and `address` from your contract deployment

```
 source:
    ...
      address: '0x9742E5C4452ccA62ce115d302756e9150CbA36Aa'
      startBlock: 31656556 
```

## PolygonBlocks

### Subgraph.yaml

[polygonBlocks/subgraph.yaml](https://github.com/cryptoalgebra/Algebra_Subgraph/blob/main/polygonBlocks/subgraph.yaml)

`network` is your network name

```
network: matic
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.algebra.finance/algebra-integral-documentation/algebra-v1-technical-reference/subgraph/subgraph-setup/subgraph-settings.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
