LuckyClaw

The lossless GameFi protocol that turns stablecoin yield into an exciting game

Videos

Description

LuckyClaw

No-Loss GameFi Protocol


Overview

In most GameFi, you pay to play and usually lose money.

In LuckyClaw, you never lose your principal. You stake stablecoins, play a claw machine daily, and win NFTs that grant yield share. Your capital is always withdrawable—no lockups, no penalties.

This is no-loss GameFi.


How It Works

Deposit stablecoins (USDT, USDC, USDe, PYUSD) to earn daily claw machine attempts. We route your capital to Aave for safe, stable yield (optimized for highest APY while maintaining safety).

You're not paying to play. You're earning plays by staking. Want out? Withdraw your principal anytime.

The yield stays in the protocol. Your capital stays yours.


Stake Tiers & Daily Attempts

Your stake amount determines how many times you can play each day:

Stake Amount

Tier

Daily Tries

$100-$299

Bronze

1

$300-$999

Silver

3

$1,000-$4,999

Gold

7

$5,000+

Platinum

15

Attempts refresh every 24 hours. Minimum stake: $100.

Want more tries? Purchase extra attempts for $19 each. No limits—buy as many as you want.


Provably Fair Randomness

Every claw attempt triggers Chainlink VRF—provably fair randomness on-chain.

The random number determines your claw strength from 1 to 100. Claw strength determines NFT rarity. The claw machine visualization in the UI reflects these probabilities, but outcomes are purely determined by Chainlink VRF.

VRF Probability Ranges:

  • 1-85: Common (85% chance)

  • 86-95: Rare (10% chance)

  • 96-99: Epic (4% chance)

  • 100: Legendary (1% chance)


NFT Yield Multipliers

These NFTs aren't collectibles. They're yield multipliers.

Each day, protocol yield is split into tier pools:

  • 5% of yield → Common NFT holders

  • 15% of yield → Rare NFT holders

  • 30% of yield → Epic NFT holders

  • 50% of yield → Legendary NFT holders

Your share = Tier Pool ÷ Active Holders in That Tier

Yield is claimable daily for maximum flexibility and security.

Example: If 3 Legendary holders exist and daily yield is $143:

  • Legendary Pool: $143 × 50% = $71.50

  • Each holder earns: $71.50 ÷ 3 = $23.83/day

If a 4th person wins a Legendary, each holder now earns $17.88/day. Natural dilution keeps the system sustainable.


NFT Crafting System

Don't like your luck? Craft lower-tier NFTs into higher rarities.

Crafting Ratios:

  • 6 Common → 1 Rare

  • 6 Rare → 1 Epic

  • 6 Epic → 1 Legendary

Why these ratios?

This matches the probability distribution:

  • Expected Commons per Rare (from drops): 85% ÷ 10% = 8.5 → 6 is generous

  • Expected Rares per Epic: 10% ÷ 4% = 2.5 → 6 creates scarcity

  • Expected Epics per Legendary: 4% ÷ 1% = 4 → 6 maintains rarity

Economic impact:

  • Crafting burns lower-tier NFTs → reduces holder count → increases yield per holder

  • Creates NFT sink mechanism → prevents infinite dilution

  • Allows dedicated players to "grind" their way to Legendary without pure luck

Example: You have 30 Commons. Craft 6→1 Rare (5 times) = 6 Rares. Then craft those 6 Rares → 1 Epic.


Unlimited Supply, Controlled Scarcity

There's no cap on NFT supply per tier.

Scarcity is controlled by:

  1. VRF probability (1% for Legendary means only 1 in 100 successful grabs)

  2. Crafting sink (burning lower tiers reduces total supply)

As more players win high-tier NFTs, individual yield shrinks naturally. This incentivizes early participation while keeping the protocol sustainable long-term.


Stake Requirements to Claim Yield

To earn yield from your NFT, you must maintain a minimum stake:

NFT Rarity

Min. Stake Required

Tier Yield Pool

Common

$100

5%

Rare

$500

15%

Epic

$2,000

30%

Legendary

$10,000

50%

What happens if you withdraw below the minimum?

You get a 7-day grace period to re-stake. After 7 days, your yield eligibility is suspended (you still own the NFT, but can't claim yield until you re-stake).

Dormant NFTs forfeit their yield share. Remaining active holders in that tier split the unclaimed yield equally.


NFT Trading

NFTs are fully tradeable. Players can:

  • Sell NFTs they can't afford to activate (e.g., win Legendary but only have $100 staked)

  • Buy high-tier NFTs to instantly access yield without grinding

  • Trade on any marketplace (OpenSea, Blur, or official LuckyClaw marketplace)

Price discovery is based on:

  • Current number of active holders (fewer = more valuable)

  • Stake requirement to activate

  • Protocol TVL (higher TVL = bigger yield pool)


Protocol Revenue Sources

LuckyClaw generates revenue through two mechanisms:

1. Extra Attempts

  • Players can purchase additional claw machine tries for $19 each

  • No daily limit—buy as many as you want

  • 100% revenue to protocol treasury

2. NFT Trading Fees

  • 3% fee on all NFT buys and sells (applied on both sides of trade)

  • Collected regardless of marketplace used

  • Revenue scales with trading volume

Revenue Example (100 Active Users):

Monthly projection:

  • 200 extra tries purchased: 200 × $19 = $3,800

  • 50 NFT trades @ avg $1,500: 50 × $1,500 × 6% (3% buy + 3% sell) = $4,500

  • Total: $8,300/month = $99,600/year

At 1,000 users: ~$996,000/year

All revenue flows to protocol treasury for development, marketing, and ecosystem growth.


Economic Example

Protocol State:

  • Total TVL: $500,000

  • Daily Yield: $500,000 × 5% APY / 365 = $68.49

Active NFT Holders (with crafting activity):

  • Common: 200 holders (many being burned for crafting)

  • Rare: 30 holders (some crafted, some dropped)

  • Epic: 8 holders (mostly crafted)

  • Legendary: 3 holders (2 crafted, 1 dropped)

Daily Yield Distribution:

  • Common Pool: $68.49 × 5% = $3.42 → $0.017/holder/day

  • Rare Pool: $68.49 × 15% = $10.27 → $0.34/holder/day

  • Epic Pool: $68.49 × 30% = $20.55 → $2.57/holder/day

  • Legendary Pool: $68.49 × 50% = $34.25 → $11.42/holder/day

A Legendary holder with $10k staked earns $11.42/day = $4,168/year = 41.7% APY (vs Aave's base 5%).

Crafting reduces holder counts over time, increasing individual yields.


Key Features

LuckyClaw combines three things:

DeFi safety — principal always withdrawable, backed by Aave
GameFi engagement — daily claw machine attempts + crafting progression
NFT utility — real yield share, tradeable, upgradeable through crafting

It's Aave meets arcade meets progression system, all in one closed loop.

Safe capital. Fair randomness. Real rewards.


Technical Architecture

Smart Contracts:

  • StakingVault: Manages deposits, withdrawals, Aave integration, extra try purchases

  • GoldenTicketNFT: ERC-721 with rarity-based yield eligibility and crafting

  • YieldDistributor: Calculates and distributes daily tier pools

  • CraftingContract: Burns lower-tier NFTs to mint higher tiers

Infrastructure:

  • Blockchain: Arbitrum Sepolia (testnet) → Arbitrum (mainnet)

  • Randomness: Chainlink VRF v2

  • DeFi: Aave v3 (USDT, USDC, USDe, PYUSD - optimized for yield)

  • Frontend: React, ethers.js, animated claw machine UI

  • Backend: Node.js for VRF orchestration


Core Stats

  • Principal: Always safe (Aave-backed, no lockups)

  • Yield Source: Aave v3 stablecoin lending (optimized for safety + APY)

  • Supported Assets: USDT, USDC, USDe, PYUSD

  • NFT Supply: Unlimited (controlled by VRF probability + crafting sink)

  • Yield Distribution: 5%/15%/30%/50% split across tiers

  • Claim Frequency: Daily (24-hour cycle)

  • Stake Tiers: $100 (1 try/day) → $5,000+ (15 tries/day)

  • Extra Tries: $19 each, unlimited purchases

  • VRF Probabilities: 85%/10%/4%/1% (Common/Rare/Epic/Legendary)

  • Crafting Ratios: 6→1 for each tier upgrade

  • Grace Period: 7 days to re-stake before losing yield eligibility

  • Trading Fee: 3% on buys and sells

  • Key Innovation: Stake-gated yield + crafting progression without principal locks


Why LuckyClaw Works

For retail players:

  • $100 gets you in the game

  • Craft your way to rare NFTs through grinding

  • Win high-tier NFTs and sell for profit

  • Never lose your principal

  • Claim yield daily for peace of mind

For whales:

  • Buy NFTs on secondary for instant yield

  • Stake $10k+ for 15 tries/day and dominant yield share

  • Purchase unlimited extra tries at $19 each

  • Diversify DeFi yield with gamified upside

  • Daily claims for maximum liquidity

For the protocol:

  • Capital retention through yield incentives (not forced locks)

  • Crafting burns NFTs → natural deflationary pressure

  • Trading fees scale with activity

  • Multi-stablecoin support maximizes yield optimization

  • Revenue from extra tries and trading fees funds growth

That's LuckyClaw.
