## Package Ecosystem Map

### Core Solana Packages

| Package          | Purpose                              |
|------------------|--------------------------------------|
| solana           | Full Solana SDK — keypairs, tx, RPC  |
| dartus           | Borsh serialization for Dart         |
| coral_xyz        | Anchor framework client              |

### When to Use What

```
Need to connect to Solana?
├── Yes → Use `solana` package
│   ├── Mobile wallet signing? → `solana_mobile_client`
│   ├── Anchor programs? → `coral_xyz`
└── No, EVM chains → `web3dart`
```

### 1. RPC Client — Never use public mainnet RPC in prod
### 3. PDAs — Seeds must EXACTLY match on-chain program
### 4. Tokens — Wallets don't hold tokens; they own accounts
### 5. Commitment — Use `confirmed` for UI, `finalized` for final money movement
