# Altude

> Gasless, non-custodial wallet infrastructure for Solana apps.

Altude is a developer platform that abstracts wallets, gas fees, and transaction infrastructure so product teams can ship Solana-powered applications without deep blockchain expertise. Users can sign in and transact without buying SOL or managing seed phrases—keys stay with the user and Altude never takes custody.

## Who It's For

- **Web3 / Solana app developers** building consumer products, games, or DeFi tools who want to remove crypto UX friction.
- **Web2 teams** entering the Solana ecosystem who prefer familiar REST API patterns over raw on-chain programming.
- **Game studios** integrating token economies into Unity, iOS, or Android titles.
- **Enterprises** needing a compliant, auditable wallet infrastructure layer.

## Core Products

### Gasless Wallet Infrastructure
Altude sponsors transaction fees on behalf of users. Users never need to hold SOL to pay gas; the application developer controls a fee-payer account through the Altude platform.

### Non-Custodial Embedded Wallets
Wallet keys are generated and held by the user (via passkeys or device-native secure storage). Altude has zero access to private keys.

### REST API
A simple HTTP API for creating accounts, requesting airdrops (devnet), checking balances, and making token transfers. Authenticated with an app-specific API key.

### Developer Dashboard
A web dashboard to register apps, obtain an App Index, monitor transaction volume, view user activity, and manage settings in real time.

| Platform       | Language       | Package / Import                    |
|----------------|----------------|-------------------------------------|
| Web / Node.js  | TypeScript     | `@altude/gasstation`                |
| Backend        | Python         | `kinetic-sdk`                       |
| iOS            | Swift          | Swift Package Manager               |
| Android        | Kotlin         | Gradle / Maven                      |

| Games          | Unity / C#     | Unity Package Manager               |

## Key Concepts

- **App Index** – A unique integer identifier for your app registered on the Altude platform. Required for all SDK calls.
- **Environment** – `devnet` (test) or `mainnet` (production).
- **Commitment** – Transaction finality level: `Processed`, `Confirmed`, or `Finalized`.
- **Keypair** – A user's public/private key pair generated from a mnemonic or secret key.

## Quick Start (TypeScript)

```typescript
import { AltudeGasStation } from '@altude/gasstation'

const client = new AltudeGasStation({
  apiKey: process.env.ALTUDE_API_KEY!,
  network: 'devnet',
})

await client.getBlockhash()
```
