Burn / Redeem Page not recognizing eligible tokens + and not burning tokens properly

Manifold Support

To Whom It May Concern,

I’ve launched a few burn pages where people are burning tokens from an OpenSea contract to redeem tokens from a new Manifold Contract on Base. For some users it’s working fine, for others, it’s not recognizing the eligible tokens in their wallet. There is especially an issue when users purchase qualified tokens to burn after the claim page has been published. Example, you need 3 tokens to qualify, someone with 1 token buys 2 more. When they go to the claim page the site is not recognizing the 2 tokens they just purchased.

A second issue is that the tokens do not seem to be burning consistently. Some are burning while others are not. Here is an example where three tokens per the transaction hash were sent to the burn address, but these tokens still remain in my wallet. https://basescan.org/tx/0xc89d2c050faa8c9f6ae74aa923c7e93b263538a6ef208fd47400bfd5ac309b85

My wallet: 0xDF464B3759a515e2bfE348Ba66A081B139eA58C3
Example Claim Page: Warhol | Manifold
Qualifying tokens to be burned: https://opensea.io/collection/get-based-by-jhekub?tab=items

gm - Thanks for reaching out. Where are you seeing that these tokens are still in your wallet?

Howdy, thanks for reporting. We’re aware of the issue and doing what we can to speed things up. Our base nodes have been having trouble and we’re in direct contact with the base team. Issue comes from our node being a few blocks behind the real world, so this causes things like

  1. Newly minted/bought token not appearing as eligible for burn
  2. Token that was just burnt seemingly eligible for burn again

The good news is for 1, that issue fixes itself after somewhere between 2-10 minutes.

For 2, the good news is that our contracts are very well written and would never allow someone to double burn a token. They will get an error if they attempt to be sneaky like that, and they will not be able to even fire off a transaction and waste gas on a tx that would fail.

If you ever have any doubt about what is and is not in your wallet, check against the following as a sanity check:

  • OpenSea
  • Your browser wallet extension
  • Etherscan

Those 3 places were probably correctly showing the tokens as no longer in your wallet post-burn.

On etherscan I can the tokens did completely burn as expected, so rest assured it’s all working, just some delays in data showing.
