@nodary/utilities

Utility helpers & metadata for interacting with the Nodary services.

Install

npm i @nodary/utilities   # or `yarn add @nodary/utilities`

Quick start

const {
  api3Contracts,
  nodaryChainIds,
  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
console.log(api3Contracts.CHAINS.length);

API surface

• Constants: nodaryAirnodeAddress, nodaryXPub, nodaryFeeds
• api3Contracts – the @api3/contracts module re-exported as-is. Use this to access CHAINS, deploymentAddresses, etc., and avoid pinning a separate @api3/contracts version in your project.
• nodaryChainIds() – list of EVM chain IDs served by Nodary.
• computeEndpointId(endpointName)
• computeTemplateId(feedName)
• computeFeedId(feedName)
• computeSponsorWalletAddress(feedName, deviationThreshold, deviationReference, heartbeatInterval)

TypeScript declarations are shipped alongside the JavaScript source (src/index.d.ts), so consumers get full type information for both the local helpers and the re-exported api3Contracts namespace.
