Historical tracing on Kaia ends on 15 September
From 15 September Kaia runs on full nodes, and how far back a call can reach changes. Tracing keeps working for recent history, roughly a day of blocks, and a state read at an explicit older block needs archive state that a full node does not hold. Everything else on Kaia stays as it is: the same endpoints on mainnet and testnet over HTTPS and WSS, the same rate limits, the same error codes, and the same method list apart from the five listed below.
