CraftLAB Protocol

CraftLAB is an on-chain crafting protocol built on Solana. Users stake SOL to mine $CRAFT tokens, then combine ingredients in a 3×3 crafting grid to produce blueprints — NFT-like on-chain receipts that grant boosted yield, governance weight, and exclusive access to protocol features.

Inspired by Minecraft's crafting mechanic, CraftLAB translates the joy of recipe discovery into a DeFi-native loop: the more strategically you craft, the higher your returns. An embedded AI advisor analyzes your resource profile and suggests optimal crafting paths.

Core Loop

1. Stake SOL  →  delegate to CraftLAB validator
2. Earn yield  →  converted to $CRAFT tokens (daily distribution)
3. Collect ingredients  →  CRAFT 🌿  SOL 💎  STONE 🪨  GOLD ⭐  MANA 🌀
4. Open crafting table  →  fill 3×3 grid with ingredients
5. Mint blueprint  →  on-chain NFT receipt (4 rarity tiers)
6. Hold blueprints  →  earn multiplied yield + governance rights

$CRAFT is the native utility and governance token of the CraftLAB protocol. It is mined exclusively through SOL staking — there is no presale, no VC allocation, and no team mint. Every token in existence has been earned by a real staker.

Token Properties

Earning $CRAFT

Mining rate is calculated per epoch (Solana epoch ≈ 2–3 days). The formula distributes emissions proportionally to each staker's share of total staked SOL:

daily_craft_earned = (your_staked_sol / total_staked_sol) × daily_emission_budget

daily_emission_budget decays by 0.5% per epoch (halving-style softcap)

Mining in CraftLAB is passive. Stake SOL once, and $CRAFT accumulates in your claimable balance every Solana epoch. No active transactions required until you choose to claim or craft.

How Staking Works

CraftLAB uses native Solana liquid staking. Your SOL is delegated to the CraftLAB validator cluster. You receive a cSOL receipt token (1:1 with SOL) that you can unstake at any time with a standard Solana 1–3 epoch cooldown period (~2–7 days).

Ingredient Generation

Alongside $CRAFT tokens, staking generates crafting ingredients. Each epoch, stakers receive a randomized ingredient drop based on their staked amount:

The crafting table is a 3×3 grid. Place ingredients into cells, and the protocol detects which recipe your arrangement matches. Confirmed recipes are executed on-chain — ingredients are burned and a blueprint NFT is minted to your wallet.

Recipe Book

On-chain Recipe Validation

Recipe detection runs entirely on-chain via a Solana program. The program reads the grid state, counts ingredient types, and matches against the recipe registry. No off-chain oracle is involved.

// Pseudo-code: on-chain recipe matcher
pub fn detect_recipe(grid: [Option<Ingredient>; 9]) -> Option<Blueprint> {
    let counts = count_ingredients(grid);
    match counts {
        c if c[CRAFT] == 9                           => Some(Blueprint::Overdrive),
        c if c[GOLD] >= 3 && c[CRAFT] >= 3          => Some(Blueprint::Gold),
        c if c[SOL] >= 2 && c[CRAFT] >= 3           => Some(Blueprint::Sol),
        c if c[CRAFT] >= 3 && c[SOL] >= 1           => Some(Blueprint::Base),
        c if c[CRAFT] >= 3                           => Some(Blueprint::Starter),
        _                                            => None,
    }
}

Blueprints are on-chain NFTs (Solana compressed NFTs via Metaplex Bubblegum) minted as a result of crafting. They represent your crafting achievement and confer ongoing protocol benefits as long as you hold them.

Blueprint Mechanics

Blueprints are held in your wallet as cNFTs. The protocol reads your blueprint holdings each epoch during yield calculation. Transferring or selling a blueprint immediately transfers the yield multiplier to the new holder.

CraftLAB integrates an AI crafting advisor powered by Meta Llama 3.1 8B via DeepInfra. The advisor analyzes your current ingredient inventory and suggests the highest-value crafting path given your resources and goals.

How to Use

Open the AI Lab section on the website or use /craft in the Telegram bot. Describe your inventory (e.g., "I have 8 CRAFT, 2 SOL, 1 GOLD") and your goal (maximize yield / save for legendary / diversify). The AI returns a step-by-step crafting plan.

API Endpoint

POST /api/ai/craft

{
  "resources": "8 CRAFT, 2 SOL, 1 GOLD",
  "goal": "maximize yield multiplier"
}

// Response
{
  "plan": "Craft a SOL Blueprint first (2 SOL + 3 CRAFT → 2× multiplier),
           then save remaining 5 CRAFT + 1 GOLD for a second drop before

  "estimated_multiplier": "2×",
  "ingredients_used": ["2× SOL", "3× CRAFT"]
}

Commands

Wallet Security

Private keys are encrypted with AES-256-GCM using a user-provided password. The encrypted blob is stored in SQLite. The password is never stored — only you can decrypt your key. If you lose your password, the key cannot be recovered.

Encryption: AES-256-GCM
KDF: PBKDF2-SHA256, 260,000 iterations
Salt: protocol-specific per-user salt
Storage: encrypted ciphertext only (never plaintext)

CraftLAB is implemented as a set of Solana programs (smart contracts) written in Rust using the Anchor framework. All programs are open source and audited prior to mainnet deployment.

Burn Mechanics

2% of all ingredients used in crafting are burned from the ecosystem supply. As crafting volume grows, burn rate increases — creating deflationary pressure on $CRAFT supply over time.
