This is very innacurate. That screenshot you show from uniswap, the highest volume pool amongst all the ethDYDX pools on uniswap has a $2k daily volume, the second largest pool has $1.2k 30 day volume, this is just insignificant compared to the $6-10 million daily volume of DYDX. A few thousand dollars is negligable compared to several millions daily volume, there can’t be any ‘dump attack’.
That was a very different situation where ICO participants lost the seed phrase which was the direct fault of those holders and sending them ATOM without the seed phrase was an exception and a process that took years to coordinate until completion. This situation is totally different, the ethDYDX holders didn’t lose any seed phrase, and as many mentioned they are long term holders who don’t follow frequent news or holders who don’t speak english, or didn’t have access to the internet due to war or many other reasons. Moreover, before the bridge was closed it was mentioned by Nethermind: ‘If this proposal passes and the Bridge support is ceased, the dYdX community—if there is sufficient interest—could consider developing a procedure and submitting a governance proposal to migrate any remaining ethDYDX on Ethereum to DYDX on the dYdX Chain’
