Core Utilities - Altude

@altude/core contains the shared primitives used by the TypeScript SDK.

Mnemonic generation

import {
  generateMnemonic,
  deriveSolanaAddress,
  deriveSolanaKeypair,
} from '@altude/core'

const mnemonic = generateMnemonic(12)
const address = await deriveSolanaAddress(mnemonic)
const keypair = await deriveSolanaKeypair(mnemonic)

Solana accounts use the hardened path m/44'/501'/<index>'/0'. Pass an index to derive another account:

const secondAddress = await deriveSolanaAddress(mnemonic, 1)

Mnemonics and derived private keys are secrets. Encrypt them at rest and never log or send them to Altude.

Direct RPC client

Most applications should call gasStation.getRpcClient(). If you need to construct the core client directly, use only values returned by transaction config:

import { createAltudeClient } from '@altude/core'

const config = await gasStation.getConfig()

const client = createAltudeClient({
  rpcUrl: config.RpcUrl,
  rpcToken: config.Token,
})

const latestBlockhash = await client.rpc
  .getLatestBlockhash({ commitment: 'finalized' })
  .send()

The client validates the URL and token, adds bearer authorization, and lazily initializes subscription support.
