The available evidence in this run only shows that multiple secondary outlets repeated a claim attributed to Tayvano. The direct X links provided by the user could not be fetched, so the alleged original statements were not validated. The Binance Square result and other search hits indicate the allegation was reported, but they do not independently establish that North Korean-linked workers in fact helped build all of the named protocols. The fetched Lookonchain page was unrelated/generic and therefore does not support the claim. Without a validated primary source from Tayvano or corroborating official/project responses, the statement remains unverified.
