# Introduction

A growing collection of small, audit-grade DeFi tools for Flare-family networks. Stateless contracts, no operator dependency, no admin fund powers — every tool routes principal directly to the user and pays itself for the gas it consumes.

The same frontend ([thanasdefitools.xyz](https://thanasdefitools.xyz)) hosts every tool as a top-level route. Pick what you need.

## What's here today

### Limit Orders — `/limit-orders`

Permissionless limit orders on Enosys V3, SparkDEX V3.1, and SparkDEX V4 (Algebra). Place a single order, walk away; when the market crosses your price, anyone can close the position and earn a share of the fees. Two sibling contracts cover both CLMM families behind one DEX picker.

→ Start with [What Are Limit Orders?](/thanasdefitools-docs/limit-orders/what-are-limit-orders.md), then [Placing an Order](/thanasdefitools-docs/limit-orders/placing-an-order.md).

### Sweeper — `/sweeper`

One-transaction batched cleanup of wallet dust. Pull N tokens via a single Permit2 batch signature, swap each through the deepest available venue (OpenOcean, BlazeSwap, Enosys V2), and receive the aggregate output as WFLR or USDT0. Or burn straight to `0x…dEaD` if no swap route exists.

→ Start with [What Is the Sweeper?](/thanasdefitools-docs/sweeper/what-is-the-sweeper.md), then [Using the Sweeper](/thanasdefitools-docs/sweeper/using-the-sweeper.md).

### FAsset Collateral LST — `/fasset-lst`

Share-based liquid staking on top of FAsset agent collateral pools. Deposit WFLR; receive **FACT** (FAsset Collateral Token, 18-decimal ERC-4626 share). The vault aggregates stake across multiple FXRP agents, harvests their FAsset minting/redemption fees on a permissionless cadence, and reinvests the swapped output as share-price growth. **Beta — newly deployed and not independently audited.**

→ Start with [What Is the FAsset Collateral LST?](/thanasdefitools-docs/fact/what-is-fact.md), then [Staking and Redeeming](/thanasdefitools-docs/fact/staking-and-redeeming.md). Read [Risks and FAQs](/thanasdefitools-docs/fact/risks-and-faqs.md) before staking.

## Why use ThanasDefiTools

* **No off-chain keeper network.** Every tool is permissionless — anyone can trigger or interact, no special infrastructure to trust.
* **No custodian.** Contracts are stateless or hold tokens only between user-signed entry and exit. No admin fund powers, no upgrade path that could change behavior under you.
* **Funds always reach the user.** Output forwards directly to the wallet that initiated the transaction. Treasuries collect a share of fees only — never principal.
* **Open source + audited.** Every contract, deploy script, and frontend file is in the public repo: <https://github.com/Thanasimos/ThanasDeFiTools>. Audit reports live alongside the contracts.

Up-to-date addresses, ABIs, and deploy parameters always in [Deployments](/thanasdefitools-docs/for-developers/deployments.md).

## Where to start (developers)

* **Building on top of these contracts?** [Architecture](/thanasdefitools-docs/for-developers/architecture.md) and [Contract Reference](/thanasdefitools-docs/for-developers/contract-reference.md) cover the state machine, the external surface, and the LOM-vs-Algebra differences.
* **Running an executor bot?** [Executor Bot Guide](/thanasdefitools-docs/for-developers/executor-bot-guide.md) walks through the profit math and the minimum code. Bots scanning across all DEXes need to watch BOTH Limit Order Manager contracts on chains where both are deployed.
