有位大兄弟制作了一个计算variational积分价值的网站,使用起来很方便: 我以市值1.5B,总积分9.3M,空投25%来计算,每分的价值是40u,1000分就是40000u 我认为这是保守估计,如果8月份variational上线了swaps和api,数据会更好看,而且以var的格局来看,空投应该不止25%,可能30%以上!

Built a DIY calculator site in a weekend — betting on "boring tools" over content After my last project (an AI debate platform) got rejected by AdSense for "low value content," I went the opposite direction: no content treadmill, no AI features, no backend. Just genuinely useful calculators. studandslab.com — 10 free calculators for woodworking and home projects (board feet, stair stringers, concrete, drywall). Everything runs client-side, so hosting is free and every visitor costs me $0.
