# Introduction

> What Picon DLMM is, and how these docs are organized

Picon DLMM is a discrete-bin liquidity market maker on Solana: a from-scratch Anchor program
(not a fork) that replaces a continuous bonding curve with a finite grid of discretely priced
**bins**. Liquidity providers deposit into specific bins instead of along a curve; a swap
consumes liquidity bin by bin until it's filled. The active bin *is* the market price — there's
no separate oracle or curve formula to invert.

## Who this is for

This documentation is written for developers integrating **with** Picon DLMM — aggregators,
routers, trading bots, other on-chain programs, or anyone building against the SDK or the
on-chain program directly. It assumes familiarity with Solana account model basics and
TypeScript or Rust.

If you're looking for the end-user app, that's [dlmm.picon.finance](https://dlmm.picon.finance).

## The one-paragraph mental model

A pool holds two tokens, X and Y, distributed across discrete price bins. Each bin trades at a
single fixed price; a bin's reserves determine whether it currently holds only Y (a bid, below
the current price), only X (an ask, above the current price), or both (the **active bin**, at
the current price). Liquidity providers deposit into a contiguous range of bins as
**positions**, represented as Token-2022 NFTs. Traders swap through the active bin and outward
in whichever direction the trade pushes the price — walking real reserves bin by bin, the same
way a real order book does, rather than integrating along a curve.

<Note>
  Picon DLMM is engineering-level assurance, not a formal guarantee. The program has layered
  test coverage (200+ Rust unit tests over the core bin/fee/arithmetic layer, an adversarial
  integration suite, and end-to-end conservation tests), continuously audited by the most
  advanced AI models.
