MetaFishtank Official Update Log

The latest Test Season patch notes, interface refinements, stability work, and quality-of-life upgrades taken directly from the English release document.

To ensure a seamless and engaging experience during the Test Seasons, the development team has been continuously refining MetaFishtank based on community feedback and internal testing. This log tracks the official version history and the improvements already shipped into the aquarium.

Cadence

Tracked releases from Feb 1 to Mar 25, 2026.

Focus

UX + Infra

Drawing flow, wallet reliability, AI review, and testnet minting.

Direction

Season Ready

Each patch reduces friction before mainnet-facing seasons.

v0.8.0

Aquarium Interface Overhaul

Feb 1, 2026

Aquarium Interface Overhaul: The main fish tank interface was redesigned to reduce clutter and create a cleaner, more immersive viewing experience.
Drawing Board Enhancements: Brush strokes became smoother, input latency dropped, and color selection became more precise for higher-quality Genesis Fish designs.

v0.8.1

Real-Time Processing

Feb 8, 2026

Real-Time Processing: Backend API infrastructure for the Anima visual recognition engine was fundamentally optimized.
Latency Reduction: Biological similarity checks now run in near real-time, effectively removing the old loading-screen delay after drawings are completed.

v0.8.5

Immersion and Social Layer

Feb 20, 2026

Audio Implementation: Ambient underwater BGM and responsive interface SFX were introduced to deepen immersion.
Ergonomic Layout: Key interactive buttons were repositioned to improve navigation on both mobile and desktop.
Follow System Activation: Players can now follow creators and top-voted accounts to streamline cross-tank daily tasks.

v0.8.6

Reliability and Balance Tuning

Mar 5, 2026

Wallet Connectivity: Fixed intermittent Sei wallet disconnects during transaction signing.
Server Stress Testing: Throughput was tuned to stay stable under peak concurrent traffic.
AI Difficulty Calibration: The Anima engine now better tolerates minor artistic variation while remaining strict against automation.
Economic Adjustments: FishPoint smart-contract logic and late-game point sinks were refined for long-term balance.

v0.8.7

On-Chain and Aquarium Motion

Mar 19, 2026

On-Chain Performance: Testnet integrations for Genesis Fish minting were completed with better gas efficiency and transaction speed.
Dynamic Animations: Fish now display fluid tail-wagging mechanics and more natural randomized swimming paths.
Interactive Environment: Screen taps can scatter fish, and improved pathfinding prevents corner-clipping.

v0.8.8

Final Drawing and Review Safeguards

Mar 25, 2026

Brush Calibration: A hotfix resolved a rare touch-screen bug that could cause brush stutter or unexpected straight lines.
Manual Appeal System: Stylized artwork that fails automated checks can now be submitted directly to the moderation team for manual approval.

Season Rules

MetaFishtank Earning Guide

English-only rulebook content for the Test Seasons, reformatted into an in-game field manual so players can quickly understand yield, costs, survival pressure, contests, and anti-bot protection.

Welcome to the MetaFishtank Test Seasons. The goal is simple: draw fish, keep them alive, earn FishPoints (FP), and qualify for the $MFT Mainnet Airdrop. The sections below cover exactly how the game works, what it costs, and what players can earn.

Synergy

4 Fish

Reach four fish to trigger the 2.0x multiplier and jump to 850 FP/day.

Early Access

3 Free

The first three fish are free, then minting costs scale up to curb inflation.

Lifespan

40 Days

Each fish stops producing FP after day 40 until an 800 FP Nutritional Pack revives it.

Proof of Work

60%

Anima requires at least 60% biological similarity to defend against scripted fish generation.

1. Daily Yields

How Much You Earn

Every Genesis Fish produces 100 FP/day. Completing daily tasks adds a fixed 50 FP/day bonus from feeding, voting, tapping the tank 10 times, and staying online for 5 minutes.

Phase	Fish	Daily Yield	Profit
Grind	1 Fish	(1 x 100 x 1.0) + 50	150 FP/day
Grind	2 Fish	(2 x 100 x 1.0) + 50	250 FP/day
Grind	3 Fish	(3 x 100 x 1.0) + 50	350 FP/day
Boom	4 Fish	(4 x 100 x 2.0) + 50	850 FP/day
Whale	5 Fish	(5 x 100 x 2.1) + 50	1,100 FP/day
Whale	6 Fish	(6 x 100 x 2.2) + 50	1,370 FP/day

Formula for 5+ fish multiplier: Multiplier = 2.0 + (N - 4) * 0.1, where N is the number of fish.

2. Minting Costs

What You Spend

The first three fish are free for early participation. Costs increase after that to prevent infinite bot inflation and pace the FP economy.

Fish #	Cost	Unlock / Timeline
1st	Free	Connect wallet and register.
2nd	Free	Log in for 2 consecutive days.
3rd	Free	Log in for 3 consecutive days.
4th	3,000 FP	The golden milestone that activates 2.0x synergy.
5th	4,500 FP	Around day 15.
6th	6,000 FP	Around day 21.
7th	8,000 FP	Around day 27.
8th	10,500 FP	Around day 33.
9th	13,500 FP	Around day 40.

Formula for 10+ fish: Cost(N) = Cost(N - 1) + 1500 + (N - 6) * 500.

3. Survival Rules

Starvation and the 40-Day Tax

Daily Hunger: Fullness drops to 0 over 24 hours. At 0, fish enter a 12-hour grace period where yield drops to 80%. After 36 hours with no food, yield drops to 0% until fed.

No Feeding Cap: The document explicitly states there are no daily feeding limits.

40-Day Metabolic Tax: Every fish has a lifespan of exactly 40 days. After that it stops producing FP until an 800 FP Nutritional Pack revives it.

Why It Exists: This soft tax prevents early whales from endlessly inflating the point pool and protects latecomer value.

4. Weekly Voting Contests

Beauty and Beast Reward Ladder

Players receive 20 votes per day with a maximum of 5 votes on a single fish. Rewards scale upward as the season matures.

Weeks 1-4

1st: 500 FP + Weekly Gold Medal
2nd-3rd: 300 FP + Weekly Silver Medal
4th-10th: 100 FP + Weekly Bronze Medal

Weeks 5-8

1st: 1,500 FP + Weekly Gold Medal
2nd-3rd: 800 FP + Weekly Silver Medal
4th-10th: 300 FP + Weekly Silver Medal

Weeks 9-12

1st: 3,000 FP + Weekly Gold Medal
2nd-3rd: 1,500 FP + Weekly Silver Medal
4th-10th: 500 FP + Weekly Silver Medal

Season Finale Grand Prize

1st Place: +20% total season FP bonus
2nd-3rd Place: +10% total season FP bonus
4th-10th Place: +5% total season FP bonus

5. Anti-Sybil and Airdrop Protection

Dual-Layer Defense System

1. Anima Engine (Proof of Human Work)

Scripts cannot click-generate fish. Players must actually draw them, and the AI requires a 60% biological similarity threshold for mint success.

2. Mainnet Verification (Proof of Capital)

At airdrop conversion time, the Sei wallet must hold a micro-amount of tokens, such as at least 2 SEI, or show genuine mainnet transaction history. Bot clusters with identical behavior or no gas money are disqualified.

Fair Airdrop Guarantee

Airdrops are not zero-sum. Points convert at a fixed base exchange rate, and leftover season tokens roll over into the next season instead of diluting player balances.
