The founding father of Yearn finance, Andre Cronje, has seen a justifiable share of criticism these days as he deployed some good contracts that ended up dropping folks cash. Cronje defended himself in a weblog submit and defined why he believes he shouldn’t be held accountable for individuals who “ape in” his testing contracts.
Cronje will usually place massive disclaimers urging folks to deal with them with warning and never simply go in as a result of he constructed it. Little could be carried out to stop this, given the permissionless nature of those merchandise. Nonetheless, Cronje was generally criticized for not deploying contracts on testnets, the place no actual cash might be misplaced. His “I check in prod” adage additionally turns some folks away, because it appears to suggest a careless angle towards safety.
Cronje defined that he does in truth check software program in a number of levels. “[The statement] exists to discourage folks from simply utilizing methods with out investigation. It does NOT imply that I don’t check,” he wrote.
Earlier than a contract makes it to the mainnet, it goes by means of a rigorous strategy of unit, interplay and composite testing. These guarantee that every a part of the contract is working as meant, right down to particular person features.
Nonetheless, a key a part of that course of is testing in manufacturing to attain essentially the most practical situations. He defined that the mainnet offers the absolute best instruments and situations, which can not simply be replicated regionally. “I’ve found points on mainnet I by no means encountered regionally, I’ve failed to duplicate mainnet methods regionally, and I’ve encountered errors regionally that I can’t replicate on mainnet,” he defined.
Moreover, there are lots of variations of present merchandise like Yearn Finance that have been deployed to mainnet with out getting found. “There are over ~22 ‘yearns’ on ETH mainnet. There are over ~5 ‘YFIs’ on ETH mainnet,” he added. In a dialog with Cointelegraph, Cronje mentioned that the rationale why his main tasks have been by no means hacked was, “sarcastically, as a result of I check in prod.” With this strategy he says he is ready to iterate over the true points that come up, as a substitute of counting on auditors to evaluation pre-production code. “And if folks simply wait until I truly launch the product, all shall be wonderful,” he added.
One case of individuals getting burned on Cronje’s good contracts concerned one among these testing playgrounds, which have been nonetheless at the least a number of weeks away from public launch.
Addressing these points, Cronje famous, “I don’t construct for speculators.” Whereas he mentioned that he couldn’t rationally perceive the individuals who rushed into his check environments, he appears to have conceded {that a} extra pragmatic strategy could also be wanted. “I’ve extra considering to do on this,” he concluded.
Within the meantime, he pledged to not use his well-known deployer deal with to conduct additional assessments. Given the variety of earlier contracts that went undiscovered, this can be sufficient to stop additional unlucky occurrences.
The submit follows one other occasion of individuals dropping cash over one among his contracts, an unnamed undertaking usually referred to by its token ticker, LBI. The contract was deployed on mainnet on Oct. 13, instantly triggering a torrent of individuals placing their cash in it — usually saying that it’s “the brand new YFI.”
The token’s value fell instantly after, with many tales of individuals dropping small fortunes over it. A barrage of criticism in opposition to Cronje was levied by many market contributors, blaming him for the loss. It’s price noting that this value decline was not the results of any sort of malfunction, because the contracts themselves weren’t compromised.
