# Solana \[Native SOL and SPL token payments]

The Solana payment method enables MPP payments on Solana using native SOL, SPL tokens, and Token-2022 assets. Solana supports two intents: **charge** for one-time payments and **session** for reserved, pay-as-you-go billing.

The reference implementation is provided by [`@solana/mpp`](https://github.com/solana-foundation/mpp-sdk), which extends [`mppx`](https://github.com/tempoxyz/mpp) with Solana-native client and server handlers.

## Installation

:::code-group
```bash [npm]
$ npm install @solana/mpp mppx @solana/kit
```

```bash [pnpm]
$ pnpm add @solana/mpp mppx @solana/kit
```

```bash [bun]
$ bun add @solana/mpp mppx @solana/kit
```

## Why Solana

Solana enables several useful capabilities for MPP:

* **Split payouts and richer settlement flows** through multiple instructions per transaction
* **Fast finality** for low-latency charge flows
* **Cheap transactions** for micropayments and fee-sponsored UX
* **Native fee payer support** so servers can sponsor network fees
* **Token flexibility** across SOL, SPL, and Token-2022 assets
* **Delegated signer options** including Ed25519 and passkey-friendly secp256r1 flows

## Choosing an intent

| | **Charge** | **Session** |
|---|---|---|
| **Pattern** | One-time payment per request | Reserve funds once, pay incrementally with vouchers |
| **Latency overhead** | One transaction or confirmed signature per request | Low after open; vouchers are off-chain |
| **Throughput** | Best for discrete purchases | Best for high-frequency metered usage |
| **Best for** | Paid API calls, downloads, fixed-price purchases | LLM APIs, streaming, repeated calls |
| **Settlement** | Immediate on-chain transfer | Reserve on-chain, settle accepted usage later |
