# Wrapper Provide Liquidity Base

> Low-level instruction to provide liquidity using base assets with external PT purchase

# createWrapperProvideLiquidityBaseInstruction

Provides liquidity to a CLMM market using base assets with an external PT purchase to reach the optimal ratio. This instruction mints SY from the base asset and buys additional PT from the market to achieve the correct SY/PT balance for the specified tick range, then deposits the liquidity.

## Usage

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

const ix = createWrapperProvideLiquidityBaseInstruction({
  depositor: depositorKeypair.publicKey,
  market: new PublicKey("market..."),
  ticks: new PublicKey("ticks..."),
  tokenPtEscrow: new PublicKey("tokenPtEscrow..."),
  tokenSyEscrow: new PublicKey("tokenSyEscrow..."),
  tokenSyDepositor: new PublicKey("tokenSyDepositor..."),
  tokenPtDepositor: new PublicKey("tokenPtDepositor..."),
  tokenFeeTreasurySy: new PublicKey("tokenFeeTreasurySy..."),
  tokenFeeTreasuryPt: new PublicKey("tokenFeeTreasuryPt..."),
  mintPt: new PublicKey("mintPt..."),
  tokenProgram: new PublicKey("TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA"),
  marketAddressLookupTable: new PublicKey("lookupTable..."),
  syProgram: new PublicKey("syProgram..."),
  exponentCoreProgram: new PublicKey("exponentCoreProgram..."),
  lpPosition: new PublicKey("lpPosition..."),
  systemProgram: SystemProgram.programId,
  rent: new PublicKey("SysvarRent111111111111111111111111111111111"),
  eventAuthority: new PublicKey("eventAuthority..."),
  program: new PublicKey("program..."),
  lowerTickKey: 0,
  upperTickKey: 100,
  minLpOut: 900_000n,
  mintSyAccountsUntil: 3,
  externalPtToBuy: 500_000n,
  externalSyConstraint: 600_000n,
