Usage

0. Generate the Snapshot

To generate the snapshot for the current period, please follow the instructions on the snapshots package README.

The file can be found at:

https://nicheman-airdrop-snapshots.s3.us-east-2.amazonaws.com/snapshot-{{period}}.json

Where {{period}} is the numeric sequential number of the distribution, starting from 1.

1. Fund the Deployer Wallet

Send to the deployer account (0x76BFB6AE7463f5c0Aad6DFeaF360EB2e0e0Bdc83) the amount of NICHEMAN being allocated for the current period.

2. Seed the Allocation

Once you got the snapshot JSON file stored, you will need to get the following values from there:

• merkleTree.root: This is the root of the merkle tree.
• droppedAmount: The amount allocated for this round of the airdrop.

Then you need to submit the following transaction:

seedAllocations(period, merkleRoot, droppedAmount)

from the deployer account.

If you don't have the private key for that account, ask Annabele or @hbarcelos for it and import it to your wallet.

NOTICE: after this transaction is mined, the NICHEMAN balance is transfered from the deployer account to the contract.

3. Claim the Rewards

In order to claim the rewards, one need to provide :

• {{address}}: The address of the juror (string).
• {{period}}: The period of the claim (number).

and also the following data from the snapshot file:

• merkleTree.claims[{{address}}].value: The amount being claimed (number)
• merkleTree.claims[{{address}}].proof: The merkle proof for that claim (string[])
