# XPR Network Developer Skill

This skill provides comprehensive knowledge for developing on XPR Network, a fast, gas-free blockchain with WebAuthn wallet support.

> **IMPORTANT DISCLAIMER: AI-Generated Smart Contract Code**
>
> Smart contracts handle real assets and are immutable once deployed. AI-generated code, including code produced with this skill, should **always be reviewed by an experienced developer** before deployment to mainnet.
>
> - **Test thoroughly on testnet** before any mainnet deployment
> - **Have code reviewed** by someone familiar with XPR Network/EOSIO smart contracts
> - **Audit critical contracts** - consider professional security audits for contracts handling significant value
> - **Understand the code** - don't deploy code you don't fully understand
>
> Claude can accelerate development and help with patterns, but it does not replace proper code review, testing, and auditing practices.

## XPR Network Overview

XPR Network is an EOS-based blockchain optimized for payments and identity:

| Feature | Description |
|---------|-------------|
| **Speed** | 0.5 second block times, 4000+ TPS |
| **Fees** | Zero gas fees for end users |
| **Accounts** | Human-readable names (1-12 chars, a-z, 1-5) |
| **Wallets** | WebAuthn support (Face ID, fingerprint, security keys) |
| **Contracts** | AssemblyScript/TypeScript with @proton/ts-contracts |
| **Storage** | On-chain tables with RAM-based pricing |

### Name Change: Proton → XPR Network

The blockchain was rebranded from **Proton** to **XPR Network** in 2024. You may see legacy references to "Proton" in:
- Package names (`@proton/cli`, `@proton/web-sdk`, `proton-tsc`)
- GitHub organization (`XPRNetwork`, formerly `ProtonProtocol`)
- Documentation and code comments
- Explorer (now `explorer.xprnetwork.org`, formerly `protonscan.io` and `proton.bloks.io`)

The token symbol remains **XPR** and all functionality is unchanged.

### Chain IDs

| Network | Chain ID |
|---------|----------|
| Mainnet | `384da888112027f0321850a169f737c33e53b388aad48b5adace4bab97f437e0` |
| Testnet | `71ee83bcf52142d61019d95f9cc5427ba6a0d7ff8accd9e2088ae2abeaf3d3dd` |

## Quick Reference

### Common CLI Commands

```bash
# Install CLI
npm i -g @proton/cli

# Set network
proton chain:set proton          # Mainnet
proton chain:set proton-test     # Testnet

# Account info
proton account myaccount -t      # With token balances

# Query table
proton table CONTRACT TABLE

# Execute action
proton action CONTRACT ACTION 'JSON_DATA' AUTHORIZATION

# Deploy contract
proton contract:set ACCOUNT ./assembly/target
```

### Common RPC Query

```javascript
import { JsonRpc } from '@proton/js';
const rpc = new JsonRpc('https://proton.eosusa.io');

const { rows } = await rpc.get_table_rows({
  code: 'CONTRACT',
  scope: 'CONTRACT',
  table: 'TABLE',
  limit: 100
});
```

### Basic Contract Structure

```typescript
import { Contract, Table, TableStore, Name, requireAuth } from 'proton-tsc';

@table("mydata")
class MyData extends Table {
  constructor(
    public id: u64 = 0,
    public owner: Name = new Name(),
    public value: string = ""
  ) { super(); }

  @primary
  get primary(): u64 { return this.id; }
}

@contract
class MyContract extends Contract {
  dataTable: TableStore<MyData> = new TableStore<MyData>(this.receiver);

  @action("store")
  store(owner: Name, value: string): void {
    requireAuth(owner);
    const row = new MyData(this.dataTable.availablePrimaryKey, owner, value);
    this.dataTable.store(row, this.receiver);
  }
}
```

### Basic Frontend Login

```typescript
import '@proton/link';  // Required for mobile wallet support
import ProtonWebSDK from '@proton/web-sdk';

const { link, session } = await ProtonWebSDK({
  linkOptions: {
    chainId: '384da888112027f0321850a169f737c33e53b388aad48b5adace4bab97f437e0',
    endpoints: ['https://proton.eosusa.io']
  },
  selectorOptions: { appName: 'My App' }
});

// session.auth contains { actor, permission }
// Use session.transact() for transactions
```

## Safety Reminders

1. **NEVER modify existing table structures** once deployed with data - this breaks deserialization
2. **Always test on testnet** before mainnet deployment
3. **Verify the target account** before deploying - wrong account = overwrite existing contract
4. **Back up ABIs** before deploying changes
5. **Use new tables** for new features instead of modifying existing ones
6. **DEX deposits MUST use empty memo** (`""`) — any other memo (e.g. `"deposit"`) causes permanent, irrecoverable fund loss. See `metalx-dex.md`.
7. **All-numeric account names** (e.g. `333555`) cause silent data loss in `get_table_rows` — see `rpc-queries.md` for workarounds.
