Carbon Points Decoder

Rust decoder for the Star Atlas Points program on Solana, generated using Carbon CLI.

Program Information

• Program ID: Point2iBvz7j5TMVef8nEgpmz4pDr7tU7v3RjAfkQbM
• Network: Solana Mainnet
• Description: Star Atlas Points program for managing player progression systems with categories, levels, and point tracking. Supports daily point limits, level upgrades, token-gated progression, and spendable points mechanics.

Features

• Decodes all Points account types
• Full instruction parsing support
• Integration with Carbon indexing framework
• Support for point categories with configurable levels
• Token-gated level progression with license types
• Daily point tracking and limits

Usage

Add this crate to your Cargo.toml:

[dependencies]
carbon-points-decoder = "0.10.0"

Decoding Accounts

use carbon_points_decoder::{PointsDecoder, PointsAccount};
use carbon_core::account::AccountDecoder;

let decoder = PointsDecoder;
let decoded_account = decoder.decode_account(&account);

if let Some(decoded) = decoded_account {
    match decoded.data {
        PointsAccount::PointCategory(category) => {
            println!("Point Category: {:?}", category);
            println!("Profile: {}", category.profile);
            println!("Point Limit: {}", category.point_limit);
            println!("Is Spendable: {}", category.is_spendable != 0);
            println!("Token Required: {}", category.token_required != 0);
            if category.token_required != 0 {
                println!("Token Mint: {}", category.token_mint);
                println!("Token Qty: {}", category.token_qty);
            }
        }
        PointsAccount::UserPointsAccount(user_points) => {
            println!("User Points Account: {:?}", user_points);
            println!("Profile: {}", user_points.profile);
            println!("Point Category: {}", user_points.point_category);
            println!("Earned Points: {}", user_points.earned_points);
            println!("Spent Points: {}", user_points.spent_points);
            println!("Current Level: {}", user_points.level);
            println!("Daily Earned: {}", user_points.daily_earned_points);
            println!("Last Earned Timestamp: {}", user_points.last_earned_points_timestamp);
        }
        PointsAccount::PointsModifier(modifier) => {
            println!("Points Modifier: {:?}", modifier);
            println!("Point Category: {}", modifier.point_category);
            println!("Can Increment: {}", modifier.can_increment != 0);
            println!("Can Decrement: {}", modifier.can_decrement != 0);
        }
    }
}

Working with License Types

The Points program uses license types to control level progression requirements:

use carbon_points_decoder::{LicenseType, PointsLevelLicenseType};

// LicenseType is used for level upgrade requirements with quantity
match license_type {
    LicenseType::None => {
        println!("No license required for this level");
    }
    LicenseType::Burn { quantity } => {
        println!("Requires burning {} tokens to unlock this level", quantity);
    }
    LicenseType::Vault { quantity } => {
        println!("Requires {} tokens transferred to vault for this level", quantity);
    }
}

// PointsLevelLicenseType is a simpler enum without quantities
match license {
    PointsLevelLicenseType::None => println!("No license"),
    PointsLevelLicenseType::Burn => println!("Burn license"),
    PointsLevelLicenseType::Vault => println!("Vault license"),
}

Working with Boolean Flags

The Points program uses u8 fields for boolean flags. Check them like this:

// Check if a point category requires tokens
if category.token_required != 0 {
    println!("This category requires token: {}", category.token_mint);
}

// Check if points are spendable
if category.is_spendable != 0 {
    println!("Points can be spent in this category");
}

// Check if tokens should be transferred to vault
if category.transfer_tokens_to_vault != 0 {
    println!("Tokens will be transferred to vault: {}", category.token_vault);
}

// Check modifier permissions
if modifier.can_increment != 0 {
    println!("This modifier can increment points");
}

if modifier.can_decrement != 0 {
    println!("This modifier can decrement points");
}

Account Types

This decoder supports all Points account types:

• PointCategory - Defines a category of points with levels, limits, and token requirements

  • Contains point limits, spendability settings, and token-gating configuration
  • Supports dynamic levels array (stored as RemainingData in the on-chain account)
  • Can require tokens for point earning or level upgrades

• UserPointsAccount - Tracks a user's points and level for a specific category

  • Stores earned points, spent points, and current level
  • Includes daily point tracking with timestamps
  • Links to a profile and point category

• PointsModifier - Grants authority to modify points for a specific category

  • Controls increment and decrement permissions
  • Used to delegate point management authority

License Types

The Points program uses two license type enums:

LicenseType

An enum with associated data for level upgrade requirements:

• None - No license or tokens required
• Burn { quantity: u64 } - Requires burning the specified quantity of tokens
• Vault { quantity: u64 } - Requires transferring tokens to a vault

PointsLevelLicenseType

A simpler enum without quantities:

• None - No license required
• Burn - Burn-type license
• Vault - Vault-type license
