💰Autobuyback

Yoink features an algorithmic buyback mechanism for all coins created on the platform. When market conditions are favorable, the system automatically purchases and burns tokens using the treasury pool, helping to stabilize prices and reduce circulating supply.

This mechanism supports long-term token health and sustainability, ensuring a more stable experience for traders. Treasury pools grow over time through the fees accumulated from trading volume.

🎯 How Autobuyback Works

Simplified Trigger Logic

🎯 Single Clear Condition:

Buyback triggers when current token price drops 10% below the EMA trend line.

• ✅ Easy to Predict: Just watch the EMA line on charts

• ✅ Fast Response: 50% EMA alpha responds quickly to recent prices

• ✅ Reliable Support: Automatic buying pressure at predictable level

• ✅ No Ambiguity: Single metric makes system transparent

How the System Works

📊 Step-by-Step Process:

1. EMA Tracking: System calculates Exponential Moving Average on every trade (50% alpha for fast response)

2. Price Monitoring: Compares current price to EMA after each transaction

3. Trigger Detection: When price falls to 90% of EMA (10% drop), buyback activates

4. Budget Allocation: System allocates 60% of treasury SOL for buyback

5. Token Calculation: Converts SOL to token amount via bonding curve math

6. Supply Cap: Limits purchase to 40% of on-curve supply per buyback

7. Internal Transfer: SOL moves from treasury vault → liquidity vault (internal only)

8. Burn Execution: Purchased tokens permanently burned from circulation

9. Event Logging: Transaction recorded, visible on Buybacks tab

⚙️ Technical Implementation

Dynamic Parameters

Parameter	Production Value	Purpose
EMA Drop Threshold	90% (9,000 bps)	Primary trigger: 10% price drop from EMA
EMA Response Speed	50% (5,000 bps)	Fast EMA response to recent price changes
Treasury Spend	60% (6,000 bps)	Uses 60% of treasury per buyback
Max Supply Per Buyback	40% (4,000 bps)	Caps single buyback to 40% of on-curve supply
Max Burn Total	25% (2,500 bps)	Lifetime burn limit relative to total supply

📊 Monitoring

Buyback Activity Tab

📈 Track Buybacks on Token Pages:

• Each coin page includes a dedicated "Buybacks" tab

• View complete history of all buyback events

• See exact timing, amounts, and transaction links

• Monitor treasury utilization and burn statistics

🔗 Transaction Visibility:

• Burn transactions are fully visible on Solana blockchain

• Buy operations happen internally within the program

• Only the burn will show as an external transaction

• The buyback "purchase" is actually an internal ledger update

Internal Mechanics Explained

🔄 How the "Buyback" Works Internally — and Why There’s No Visible SOL Inflow on Solana Explorer:

• SOL moves internally from the treasury vault to the bonding curve liquidity pool

• The token quotation updates to reflect the increased SOL reserves

• No actual SOL leaves the bonding curve — it’s simply an internal transfer between vaults (treasury → AMM vault)

• Result: Treasury balance decreases, curve liquidity increases, and tokens are burned

💡 Why You Only See Burns on Solana Explorer:

• The “purchase” is recorded as an internal AMM ledger adjustment

• Only the final burn transaction appears on-chain, since SOL never leaves the bonding curve account — it’s just reallocated between internal vaults

🔥 Autobuyback is enabled by default for all tokens and operates automatically without any user intervention required.
