LinkPool: Crowdsale Completion, Unsold Portion Distribution and Token Transfers

Unsold Portion Distribution

In our last update, we announced that the all unsold portions of our crowdsale will be distributed to each contributor depending on how much they’ve contributed. I’m pleased to say that this has been completed, and the latest version of the contract has the new amounts added on-top.

Contract Address: 0x18824bcda34ad2f4e4209521d9e49bd216fda6a3

To check your amount in the contract, on the “Read Contract” tab, enter the address you contributed from and you’ll see similar to:

To explain this further:

key : This is your unique key in the contract, mapped to your address. If you transfer all your tokens away and then some back, you will still retain the same key. percentage : The % you’ll get of all tokens that get sent to this contract, for example from staking or NaaS. To calculate the exact percentage, divide your amount by 1000. So for the above screenshot, this would result in 37.000, i.e 37%. The image above is from one of the LinkPool wallets. shareTokens : These are the transferable token representation of the percentage you own. The value given to you is in the smallest unit for Ethereum, wei. You can convert this value by using a website like http://eth-converter.com/ to give you your ether value.

We encourage everyone to check their new contribution amount in-case of any queries. We will be locking the contract on the 10th of August making it completely immutable.

Distribution Calculation

The way distribution was executed was by a Truffle framework script that migrated the data from the old contract, increased each contributors share, deploying a new contract and then setting all the amounts as-if they was what was contributed originally.

For full transparency, this was uploaded to the GitHub repository for the PoolOwners contract and can be found here.

The distribution calculation from that script:

let contribution = Number(contributors.stakedAmounts[i].amount); let extraShare = contribution / totalAmount * unsold;let totalContribution = contribution + extraShare;let quoitent = (totalContribution / precision >> 0); totalContribution = quoitent * precision;

This snippet above shows how the distribution amount is calculated for each contributor. The contribution amount is divided by the total contributed (701.2 ether) then multiplied by the unsold amount. This provides the wei amount to add onto the existing contribution.

After that, the full amount is divided by the minimum precision of 0.04 ether taking the quotient, and then the quotient multiplied by the precision to get the complete amount. The reason we have to use a precision will be explained under token transfers.

Distribution Process

To give a step by step process of how distribution works:

Once the balance in the contract is greater than the minimum distribution threshold, distribution can be started by any one with an active ownership in the pool. When distribution is active, each owner can then claim their tokens, instantly adding them to their balance allowing them to be withdrawn at any time. Once every active owner has claimed their tokens, this will then mark distribution as complete.

That process can be repeated at any time as long as the contract balance is greater than the minimum threshold and distribution isn’t already active.

An unfortunate side-effect of this implementation is that the transferring of LP tokens between wallets is blocked when token distribution is active. This is to stop any problems during distribution and current percentages changing in the contract.

In regards to token claiming, any pool owner can claim any other active owners tokens on behalf of them. This is to ensure that the contract is never waiting on any one person to complete distribution; also allowing LinkPool to claim all tokens on behalf of owners, subsequently paying the gas.

Token Transfers

The transferring of LP crowdsale tokens between wallets is now unlocked. Since the crowdsale dashboard isn’t yet completed, the only way to to transfer tokens is to manually interact on Etherscan or MEW.

To show how this is done on Etherscan:

First click the Write Contract tab on the contract address. Scroll down to sendOwnership In the _address field, enter the address of the wallet you’d like to send the tokens to. In the _amount field, enter the amount in wei you’d like to send. Remember, the amount has to be divisible by 0.04 ether. For example, 0.16 ether is fine, but 0.18 ether isn’t. `sendOwnership` contract functionality

The reason for the minimum precision amount of 0.04 ether is due to the smallest percentage possible being 0.001%, represented as 1 in the contract. If amounts not divisible by the minimum precision was allowed, it would result in the total percentage of all owners in the contract to decrease from 100%.

Precision can be increased so the minimum percentage is 0.0001% for example, but this then increases the gas costs overall. We find the precision of 5 to be a perfect balance of gas cost and function.

Crowdsale Dashboard

The development of the crowdsale dashboard is now underway, with the first mocks being designed. This dashboard will have the following functionality:

Show you a simple summary of your ownership, the percentage and the amount of tokens you hold. The amount of tokens you’ve earned while having active ownership, current amount of tokens unclaimed. Previous distributions, how many tokens were distributed, what token was distributed and the amount of owners that claimed. The easy ability to transfer LP tokens to another wallet.

With this now being in active development, we hope we can release it soon!
