+# Eartton Token Standard
+
+## Simple Summary
+An advanced token standard for TON that extends Jetton with integrated DeFi capabilities.
+
+## Abstract
+Eartton introduces a comprehensive token standard that builds upon TEP-74 (Jetton) to provide built-in mechanisms for liquid staking, AMM functionality, dynamic tokenomics, and decentralized governance. This standard aims to simplify DeFi development on TON while maintaining high efficiency and security.
+
+## Motivation
+Current DeFi development on TON requires multiple separate contracts and protocols for advanced functionality, leading to:
+1. Increased complexity and development time
+2. Higher gas costs from multiple contract interactions
+3. Potential security risks from complex integrations
+4. Fragmented liquidity across protocols
+
+Eartton solves these issues by providing an all-in-one solution that maintains compatibility with existing infrastructure while adding advanced functionality.
+
+## Specification
+
+### Overview
+Eartton implements all standard Jetton interfaces and adds the following components:
+
+1. Master Contract (Token Management)
+2. Staking Contract (Liquid Staking)
+3. Pool Contract (AMM)
+4. Wallet Contract (Extended Functionality)
+
+### Contract Interfaces
+
+#### Master Contract
+```func
+;; Storage Structure
+storage#_ total_supply:Coins
+         owner_address:MsgAddress
+         content:^Cell
+         jetton_wallet_code:^Cell
+         burn_rate:uint16
+         staking_apr:uint16
+         farming_pool_size:Coins
+         paused:Bool
+         blacklist:^Cell
+         governance:^Cell
+         last_distribution_time:uint64
+         dynamic_params:^Cell = Storage;
+
+;; Required Methods
+- get_wallet_address(slice owner_address)
+- get_jetton_data()
+- get_eartton_params()
+```
+
+#### Staking Contract
+```func
+;; Storage Structure
+storage#_ total_staked:Coins
+         exchange_rate:uint32
+         sttoken_supply:Coins
+         master_address:MsgAddress
+         stakers:^Cell
+         rewards_pool:Coins = Storage;
+
+;; Required Methods
+- stake(uint128 amount, uint32 lock_period)
+- unstake(uint128 amount)
+- claim_rewards()
+```
+
+#### Pool Contract
+```func
+;; Required Methods
+- swap(uint128 amount_in, uint128 min_amount_out)
+- add_liquidity(uint128 amount_a, uint128 amount_b)
+- remove_liquidity(uint128 lp_amount)
+```
+
+### Operation Codes
+```func
+const int op::transfer = 0xf8a7ea5;
+const int op::mint_sttoken = 0x1234F201;
+const int op::swap = 0x1234F301;
+const int op::propose_vote = 0x1234F001;
+// ... other operation codes
+```
+
+### Features
+
+#### 1. Dynamic Tokenomics
+- Adaptive burn rate based on market conditions
+- Dynamic staking APR
+- Automatic parameter adjustments
+
+#### 2. Liquid Staking
+- Immediate stToken minting
+- Flexible lock periods
+- Compound rewards
+
+#### 3. Built-in AMM
+- Constant product formula
+- Dynamic fees
+- Slippage protection
+
+#### 4. Governance
+- Parameter modification
+- Access control
+- Transparent execution
+
+### Security Considerations
+
+1. Front-running Protection
+```func
+;; Example implementation
+if (block.timestamp > deadline) {
+    throw(error::deadline_exceeded);
+}
+```
+
+2. Reentrancy Guard
+```func
+;; Example implementation
+if (in_progress) {
+    throw(error::reentrant_call);
+}
+in_progress = true;
+```
+
+3. Access Control
+```func
+;; Example implementation
+if (!equal_slices(sender_address, owner_address)) {
+    throw(error::unauthorized);
+}
+```
+
+## Rationale
+The design decisions in Eartton prioritize:
+1. Gas efficiency
+2. Security
+3. Ease of integration
+4. Backward compatibility
+
+## Backwards Compatibility
+Eartton maintains full compatibility with TEP-74 (Jetton) while extending functionality.
