📦 A smart contract that distributes a balance of tokens according to a Merkle root

merkle-distributor's Issues

Is it possible to retrieve/burn tokens inside the merkle distributor?

There was a faulty configuration (I didn't take decimals into account), and tokens were sent to the ATA before realizing the mistake. Is there any remedy?

Or do I treat those tokens as lost forever?

Claim doesn't work in next.js in Browser

The bug is connected to this line:
https://github.com/saber-hq/merkle-distributor/blob/master/src/utils/bytes32.ts#L5-L6

const buf = new Uint8Array(Buffer.alloc(32));
b.copy(buf, 32 - b.length);

Before copying, the next.js polyfill for Buffer will check if buf is a Buffer, and it evaluates to false.

Proposed Solution

Usage instructions?

It's a little bit unclear how to use this. There is clearly a need for a JSON file with the amounts and the owner addresses. It would be very good to add something about this to README.
