# Intents & Batching

Paragon Flow upgrades swapping from a simple transaction model to an intent-based execution system.

### Intents & Batching

Paragon Flow upgrades swapping from a simple transaction model to an intent-based execution system.

Instead of sending a transaction directly, users define their desired outcome and allow the system to execute it under optimal conditions.

***

### What Is an Intent?

Instead of executing a trade immediately, you:

* define what you want
* set your minimum acceptable output (minOut)
* sign an intent

Paragon then handles execution on your behalf.

***

### How It Works

#### 1. You Sign an Intent

* no transaction is sent to the public mempool
* no early exposure to bots
* only a signed instruction is created

***

#### 2. Batching Begins

Your intent is grouped with others into a short execution window.

This enables:

* improved routing efficiency
* better liquidity access
* coordinated execution

***

#### 3. Solvers Compete

Independent solvers:

* analyze all batched intents
* route across available liquidity

including:

* Paragon liquidity
* external liquidity (via 1inch and future integrations)

They compete to find the best execution path.

***

#### 4. Best Route Selection

The system selects the optimal proposal based on:

* highest output
* lowest cost
* execution reliability

***

#### 5. Atomic Execution

Trades are executed:

* in a single batch
* atomically
* with reduced frontrunning risk

***

#### 6. Settlement

On-chain settlement:

* verifies execution
* enforces minimum output (minOut)
* records execution data

👉 Any execution improvement and distribution logic is handled at settlement and explained separately.

***

### Why Intents Improve Execution

#### Better Pricing

* multi-hop routing
* cross-venue aggregation
* solver competition

***

#### More Efficient Execution

* batched order flow
* improved liquidity access
* reduced fragmentation

***

#### Execution Protection

* minimum output enforcement
* automatic revert if conditions are not met
* optional fallback to classic swap

***

### Proof-of-Best-Execution (PoBE)

Each trade records:

* expected minimum output
* actual execution output

Displayed in the interface as:

👉 “You saved X%”

All data is transparent and verifiable on-chain.

***

### Key Components

* **Trader** → signs intent
* **Batcher** → groups intents
* **Solvers** → compete for execution
* **FlowSettlement** → verifies and executes

***

### Fallback Protection

If no solver can meet execution requirements:

* the trade reverts (default)
* or executes via the standard router (if enabled)

Users are always protected by their defined minimum output.

***

### Evolution

**Phase 1**

* external routing (via 1inch)

**Phase 2**

* Paragon pools + external routing

**Phase 3**

* full multi-venue solver optimization

***

### Summary

Paragon Flow introduces a new execution model based on:

* intent-based trading
* batch-based settlement
* solver-driven routing

Paragon Flow is the execution engine that powers optimized trading across the protocol.

***

### Why Intents Are Better

#### MEV Resistance

* no public mempool exposure
* no sandwich attacks
* private execution

***

#### Better Pricing

* multi-hop routing
* cross-venue aggregation
* solver competition

***

#### Shared Value

* you keep the savings
* LPs are rewarded
* protocol aligns incentives

***

#### Smart Execution

* enforced minOut
* automatic revert if not met
* optional fallback to classic swap

***

### Proof-of-Best-Execution (PoBE)

Every trade is verified and recorded:

* your expected output
* actual output
* surplus generated
* how it was distributed

Displayed in UI as:

👉 **“You saved X%”**

Fully transparent and on-chain.

***

### Key Components

* **Trader** → signs intent
* **Batcher** → groups intents
* **Solvers** → compete for execution
* **FlowSettlement** → verifies & executes

***

### Fallback Protection

If no solver can beat your minimum:

* trade reverts (default)
* OR executes via classic router (if enabled)

You are always protected.

***

### 🌐 Evolution (Important)

#### Phase 1

* external routing (1inch, others)
* Paragon pools only

#### Phase 2

* internal Paragon pools + external routing

#### Phase 3

* full multi-venue optimization

***

### 🧾 Summary

Paragon Flow introduces a new execution model:

* intent-based trading
* batch-based settlement
* solver-driven routing
* surplus sharing
