参数化降雨险 · 结算依据是链上降雨读数,不是查勘Parametric rain insurance · settled by on-chain rainfall, not by loss adjustment

只读模式不签名、不发交易:能看链上全部数据,不能投保或注资 —— 交易仍然只能由钱包(MetaMask)签名。Read-only mode signs nothing: you can read everything, but buying and funding still need MetaMask.
三步上手:① 点一个城市 → ② 选保障时长 → ③ 看链上算出来的保费与触发阈值。
不需要钱包、不花钱:这三步只发只读的 eth_call,页面不签名、不广播任何交易
(真要投保才用得上钱包)。 Three steps: pick a city → pick a cover window → read the premium and trigger computed on-chain. No wallet and no gas — these are read-only eth_call requests; nothing is ever signed or broadcast.

理赔只看投保后的增量:投保当刻的链上读数记为基线,
之后新增累计降雨 ≥ 阈值 才进入判定。
实赔按国标档位打折:暴雨 50% / 大暴雨 75% / 特大暴雨 100%。 Claims use the post-purchase increase: the reading at purchase is the baseline, and only new rainfall ≥ the threshold enters judgement. A payout is scaled by tier — 50% / 75% / 100%.
