  computeFeedId,
  computeSponsorWalletAddress,
} = require("@nodary/utilities");

console.log(nodaryChainIds()); // → [1, 56, 137, 42161, ...]
console.log(computeFeedId("BTC/USD")); // 0xd888b92f9d71afedd0a012622c0d1d5368fc0dc0ff1d30bb16266afcd49c2c17
console.log(computeSponsorWalletAddress("BTC/USD", 1000000, 0, 86400)); // 0x82D117e7AdEd3fC8A9266252899B21C843dDC4B2 for 1% deviation threshold, 0 deviation reference, 1 day heartbeat interval
