Mine $DYSN with Points

There are two ways to earn Points:

1. When a user with membership makes a deposit in the dual investment.
2. When a referee swaps their Points for $DYSN, the user can receive 1/3 of the Points.

We will explain how to check user's Points balance and guide you through the process of swapping Points for $DYSN.

Retrieving Points balance

Let's make a async function to retrieve user's balance of Points. For further details, please refer to IFarmRewardInfo to verify data types.

Exploring farmInfo.userInfo, we uncover the following:

1. spBalance is in BigInt format with 18 decimals.
2. coolDownTime is represented in BigInt format as a Unix timestamp (in seconds). Users are unable to swap points when the current time is earlier than coolDownTime.

import { getFarmRewardInfo } from '@dyson-finance/dyson-interface-sdk/reads'
import { IFarmRewardInfo } from '@dyson-finance/dyson-interface-sdk/dist/constants'

//...
    const client = getPublicClient({
      chainId: selectChain,
    })
    const farmInfo: IFarmRewardInfo = await getFarmRewardInfo(client, {
      farmAddress,
      account: (account as Address) || zeroAddress,
    })

//...

Calculate the exchange rate

We have created a function to compute the exchange rate from Points to $DYSN. However, it requires fetching certain data with the IFarmRewardInfo interface.

For a detailed explanation of the formula implemented here, please refer to our documentation on convert Points to $DYSN.

import {
  getCurrentReserve,
  globalApToGOV,
} from '@dyson-finance/dyson-interface-sdk/calculations'

//...
  const dysnAmountOut = useMemo(() => {
    const globalW = farmInfo.w
    const reserveGlobal = getCurrentReserve(
      farmInfo.rewardRate,
      farmInfo.lastReserve,
      farmInfo.lastUpdateTime,
    )
    return globalApToGOV(parseFloat(formatUnits(spBalance, 18)), reserveGlobal, globalW)
  }, [
    farmInfo.w,
    farmInfo.rewardRate,
    farmInfo.lastReserve,
    farmInfo.lastUpdateTime,
    spBalance,
  ])
//...

Swap action

For the rate of swap point to $DYSN amount, please visit farm.

User can help others to swap their points to the governance token($DYSN). During the process, there are some key rules should be noticed.

• Accessibility: Any third party can trigger this function.
• Cooldown Requirement: Users can only perform a swap after their cooldown period ends, determined by their generation in the referral system.
• Referral System Registration: To initiate a swap, users must be registered in the referral system. Upon swapping, the user's referrer receives 1/3 of the user's Points.

import { prepareSpSwap } from '@dyson-finance/dyson-interface-sdk/actions'

const config = await walletClient.simulateContract({
  address: FarmContractAddress,
  ...prepareSpSwap(walletClient, address),
})
await walletClient.writeContract(config.request)
