npm-package-near-async-key

NEAR Protocol utility package for managing and querying access keys on the NEAR blockchain.

Installation

npm install npm-package-near-async-key

Functions

• getAccessKeys(accountId) — Fetch all access keys for a NEAR account
• getAccessKey(accountId, publicKey) — Get details of a single access key
• generateKeyPair() — Generate a new ED25519 key pair
• verifyKeyExists(accountId, publicKey) — Check if a public key exists on an account
• countFullAccessKeys(accountId) — Count full-access keys on an account
• derivePublicKey(privateKey) — Derive a public key from a private key

Usage

import { getAccessKeys, getAccessKey, generateKeyPair, verifyKeyExists, countFullAccessKeys, derivePublicKey, } from 'npm-package-near-async-key';

// Fetch all access keys const keys = await getAccessKeys('alice.near'); console.log(keys); // [{ public_key: 'ed25519:...', access_key: { nonce: 1, permission: 'FullAccess' } }]

// Get a single access key const key = await getAccessKey('alice.near', 'ed25519:ABC123...'); console.log(key.nonce, key.permission, key.block_height);

// Generate a new key pair const { publicKey, secretKey } = generateKeyPair();

// Verify a key exists on an account const exists = await verifyKeyExists('alice.near', 'ed25519:ABC123...');

// Count full-access keys const count = await countFullAccessKeys('alice.near');

// Derive public key from private key const pubKey = derivePublicKey(secretKey);
