# Deposit Liquidity

> Low-level instruction to create a new LP position and deposit liquidity

# createDepositLiquidityInstruction

Builds a raw instruction to create a new LP position and deposit liquidity at specified tick boundaries. This initializes a fresh position account and deposits PT and SY tokens into the pool within the defined tick range.

## Usage

```typescript theme={null}
import { createDepositLiquidityInstruction } from "@exponent-labs/exponent-sdk/client/clmm";
import { Keypair, PublicKey, SystemProgram } from "@solana/web3.js";

const lpPositionKeypair = Keypair.generate();

const ix = createDepositLiquidityInstruction({
  depositor: depositorKeypair.publicKey,
  market: marketAddress,
  ticks: ticksAccount,
  lpPosition: lpPositionKeypair.publicKey,
  tokenPtSrc: depositorPtTokenAccount,
  tokenSySrc: depositorSyTokenAccount,
  tokenPtEscrow: marketPtEscrow,
  tokenSyEscrow: marketSyEscrow,
  addressLookupTable: lookupTableAddress,
  tokenProgram: tokenProgramId,
  syProgram: syProgramId,
  systemProgram: SystemProgram.programId,
  eventAuthority: eventAuthorityPda,
  program: clmmProgramId,
  lowerTickKey: 100,
  upperTickKey: 200,
  maxSyIn: 1_000_000_000n,
  maxPtIn: 500_000_000n,
});
```
