Pair Addresses

Bu açık kaynak protokol/SDK referansı TurkDex markasıyla sunulan uyarlamadır; sayfadaki entegrasyon örnekleri Turkchain’de etkin özelliklerin garantisi değildir. Ağ, kontrat ve işlem değerlerinde yalnızca bu kurulumun doğrulanmış ENV/registry bilgilerini kullanın.

getPair

The most obvious way to get the address for a pair is to call getPair on the factory. If the pair exists, this function will return its address, else address(0) (0x0000000000000000000000000000000000000000).

• The "canonical" way to determine whether or not a pair exists.
• Requires an onchain lookup.

CREATE2

Thanks to some fancy footwork in the factory, we can also compute pair addresses _without any onchain lookups_ because of CREATE2. The following values are required for this technique:

• token0 must be strictly less than token1 by sort order.

• Can be computed offline.
• Requires the ability to perform keccak256.

Examples

TypeScript

This example makes use of the TurkDex v2 SDK. In reality, the SDK computes pair addresses behind the scenes, obviating the need to compute them manually like this.

import  from '@uniswap/v2-sdk'
import  from '@ethersproject/solidity'
import  from '@ethersproject/address'

const token0 = '0xCAFE000000000000000000000000000000000000' // change me!
const token1 = '0xF00D000000000000000000000000000000000000' // change me!

const pair = getCreate2Address(
  FACTORY_ADDRESS,
  keccak256(['bytes'], [pack(['address', 'address'], [token0, token1])]),
  INIT_CODE_HASH
)
