On Thursday 24 March someone going by the name of HashArt on OpenSea found an exploit in the Orthoverse NFT contract, allowing the crafting of transactions that allow any NFT in the contract to be moved to any address.
Obviously this is not a good state of affairs. As a result, Richard and I fixed the contract, finally wrote a test suite, corrected other niggling but only cosmetic bugs we'd found, and added artificial scarcity to the contract.
And then we migrated all the existing tokens into the new contract, which turned out to be incredibly painful, and quite expensive ($5000 in gas).
The scarcity thing may sound like an oxymoron for a contract that involves 1.5*10⁴⁸ tokens, but we managed it.
Listen to the episode for a full explanation and other fun Orthoverse stuff.
The Orthoverse is doomed! But not quite yet.
