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

Algebra

Constants.ts

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

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

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

FarmingCenterAddress is the FarmingCenter contract address from your contracts deployment

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