Zap-In Responses

Response type	Fields

`ZapInDlmmResponse`	`setupTransaction?`, `swapTransactions`, `ledgerTransaction`, `zapInTransaction`, `cleanUpTransaction`
`RebalanceDlmmPositionResponse`	`setupTransaction`, `initBinArrayTransaction?`, `rebalancePositionTransaction?`, `swapTransaction?`, `ledgerTransaction`, `zapInTransaction`, `cleanUpTransaction`, `estimation`

Zap-Out Methods

Method	Route source	Notes
`zapOut`	Caller-supplied whitelisted payload	Lowest-level builder. Use only when you already know the downstream account order and amount offset.
`zapOutThroughJupiter`	Jupiter V6 swap-instruction response	Builds ATAs, calculates reverse amount offset, forwards Jupiter accounts, and unwraps SOL when needed.
`zapOutThroughDammV2`	DAMM v2 pool state and `createDammV2SwapPayload`	Builds DAMM v2 remaining accounts and uses amount offset `8`.
`zapOutThroughDlmm`	DLMM pair state and `createDlmmSwapPayload`	Builds DLMM remaining accounts, including transfer-hook slices when required, and uses amount offset `8`.

Estimator Functions

Function	Use
`estimateDlmmDirectSwap(params)`	Estimate whether and how much to swap when the input mint is token X or token Y. Compares DLMM and Jupiter routes.
`estimateDlmmIndirectSwap(params)`	Estimate split amounts to swap an unrelated input token into token X and/or token Y through Jupiter.
`estimateDlmmRebalanceSwap(params)`	Estimate the swap needed after removing liquidity from an existing DLMM position before zapping back in.

Jupiter Helpers

Function	Use
`getJupiterQuote(inputMint, outputMint, amount, maxAccounts, slippageBps, dynamicSlippage, onlyDirectRoutes, restrictIntermediateTokens, config?)`	Fetch a Jupiter quote. Returns `null` when the request fails or the endpoint rejects it.
`getJupiterSwapInstruction(userPublicKey, quoteResponse, config?)`	Fetch Jupiter swap instructions for a quote. Throws when the request fails.
`buildJupiterSwapTransaction(user, inputMint, outputMint, amount, maxAccounts, slippageBps, quote?, config?)`	Build a transaction containing the Jupiter swap instruction. Reuses a supplied quote when provided.

getJupiterQuote(..., maxAccounts, ..., onlyDirectRoutes, ...) forwards those flags to Jupiter /swap/v1/quote. Direct zap-in estimators pass onlyDirectRoutes=true and maxAccounts=50. That is not equivalent to a Jupiter UI quote. Slippage on the quote does not mean the output is a fair market vs the input. Integrations must validate outAmount before signing. See Jupiter customer support.

DAMM v2 Helpers

Function	Use
`getDammV2Pool(connection, poolAddress)`	Fetch a DAMM v2 pool state through `@meteora-ag/cp-amm-sdk`.
`getDammV2RemainingAccounts(poolAddress, user, userInputTokenAccount, userTokenOutAccount, tokenAProgram, tokenBProgram, poolState)`	Build account metas for DAMM v2 `swap2` in zap-out flows.
`createDammV2SwapPayload(amountIn, minimumSwapAmountOut)`	Serialize DAMM v2 `swap2` payload data for generic `zapOut`.
`isSingleSidedA(poolState)` / `isSingleSidedB(poolState)`	Detect DAMM v2 single-sided pool boundary states.

DLMM Helpers

Function	Use
`getLbPairState(connection, lbPair)`	Fetch a DLMM pair state.
`getDlmmRemainingAccounts(connection, lbPair, user, userInputTokenAccount, userTokenOutAccount, tokenXProgram, tokenYProgram, lbPairState)`	Build DLMM swap remaining accounts and `RemainingAccountInfo`.
`createDlmmSwapPayload(amountIn, minimumSwapAmountOut, remainingAccountsInfo)`	Serialize DLMM `swap2` payload data for generic `zapOut`.
`getBinArrayBitmapExtension(connection, binArray)`	Decode a bin array bitmap extension account when it exists.
`getNextBinArrayIndexWithLiquidity(...)`	Scan DLMM bitmap state for the next bin array with liquidity.
`toProgramStrategyType(strategy)`	Convert DLMM SDK strategy enum values into Zap IDL enum values.
`convertAccountTypeToNumber(accountType)`	Encode DLMM remaining-account slice account types.

`deriveDammV2EventAuthority()`	Derive DAMM v2 event authority.
`deriveDammV2PoolAuthority()`	Derive DAMM v2 pool authority.

`getOrCreateATAInstruction(connection, tokenMint, owner, payer, allowOwnerOffCurve, tokenProgram)`	Return an ATA and an idempotent creation instruction.
`getTokenProgramFromMint(connection, mint)`	Detect SPL Token versus Token 2022 from mint ownership, defaulting to SPL Token on lookup failure.
`getTokenAccountBalance(connection, tokenAccount)`	Return a token-account balance string, or `"0"` when the account lookup fails.
`wrapSOLInstruction(from, to, amount, tokenProgram?)`	Build native SOL wrap instructions.
`unwrapSOLInstruction(owner, receiver, allowOwnerOffCurve?)`	Build a wrapped SOL close-account instruction.
