+# pump-parser
+
+Solana transaction parser focused on swap, liquidity, migration, platform, MEV, compute budget, and compact binary persistence workflows.
+
+The package works with a normalized `RawTx` representation, parses it into `Tx`, and emits one or more `Swap` records when a supported protocol action is found.
+
+## Features
+
+- Parse Solana RPC / Yellowstone transactions into local `RawTx`.
+- Extract swap and liquidity events into `Tx.Swaps`.
+- Preserve transaction metadata such as slot, block time, signer, fee, CU limit, CU consumed, token balances, platform fees, and MEV agent hints.
+- Encode/decode parsed transactions with the `PTXB` / `PTXS` binary formats.
+- Encode/decode raw transactions with the `PRTX` / `PRTS` / `PRBS` binary formats.
+- Stream decode large `PTXS` / `PRTS` payloads without loading every transaction into memory.
+- Merge `PTXS` batches while remapping address tables.
+
+## Supported Parsers
+
+Default parser initialization enables the hot-path Pump parsers only:
+
+- Pump
+- Pump AMM
+
+`EnableAllParsers()` additionally enables:
+
+- Meteora DLMM
+- Meteora Pools
+- Meteora DAMM v2
+- Meteora Bonding Curve
+- Orca Whirlpool
+- Raydium AMM v4
+- Raydium CLMM
+- Raydium CPMM
+- Raydium LaunchLab
+
+Use `InitParser(WithMeteoraDlmm())` when only Meteora DLMM should be added to the default parser set.
+
+## Installation
+
+```bash
+go get github.com/thloyi/pump-parser
+```
+
+This module currently declares `go 1.25.1` in `go.mod`.
+
+## Basic Usage
+
+```go
+package main
+
+import (
+	"fmt"
+	"log"
+
+	pump_parser "github.com/thloyi/pump-parser"
+)
+
+func main() {
+	// Enable all known parser programs. Omit this call to keep the default
+	// Pump + Pump AMM parser set.
+	pump_parser.EnableAllParsers()
+
+	var rawTx *pump_parser.RawTx
+	// Fill rawTx from RPC, Yellowstone, JSON, or RawTx binary decoding.
+
+	tx, err := pump_parser.ParseRawTx(rawTx)
+	if err != nil {
+		log.Fatal(err)
+	}
+
+	fmt.Println("tx:", tx.GetTxHash())
+	for _, swap := range tx.Swaps {
+		fmt.Printf("%s %s base=%s quote=%s pool=%s user=%s\n",
+			swap.Program,
+			swap.Event,
+			swap.BaseAmount,
+			swap.QuoteAmount,
+			swap.Pool,
+			swap.User,
+		)
+	}
+}
+```
+
+## Swap Result
+
+`ParseRawTx` returns a `Tx`. A transaction can contain zero, one, or multiple parsed swap records in `Tx.Swaps`.
+
+Each `Swap` describes one protocol-level swap, liquidity, migration, or pool operation that the parser can normalize. The most important fields are:
+
+| Field | Meaning |
+| --- | --- |
+| `Program` | Normalized protocol name, such as `Pump`, `PumpAMM`, `MeteoraDLMM`, `RaydiumV4`, or `OrcaWhirPool`. |
+| `Event` | Normalized action, such as `buy`, `sell`, `add_liquidity`, `remove_liquidity`, `create`, `complete`, or `migrate`. |
+| `TxIndex` | Approximate execution order across outer and inner instructions. |
+| `InstrIdx` / `InnerIdx` | Outer instruction index and inner instruction index where the swap was found. |
+| `Pool` | Pool, pair, bonding curve, or market account for the parsed action. |
+| `BaseMint` / `QuoteMint` | Base and quote mint accounts after parser normalization. |
+| `BaseTokenProgram` / `QuoteTokenProgram` | Token program for each side, useful when Token-2022 is involved. |
+| `BaseMintDecimals` / `QuoteMintDecimals` | Decimals used to interpret raw token amounts. |
+| `User` | User or effective owner account for the action. If the parsed user is not on-curve, the parser may fall back to the transaction signer. |
+| `BaseAmount` / `QuoteAmount` | Actual parsed base-side and quote-side amounts, stored as `decimal.Decimal`. |
+| `BaseReserve` / `QuoteReserve` | Pool reserves when the protocol event or accounts expose them. |
+| `UserBaseBalance` / `UserQuoteBalance` | User token balances after the transaction when available from token balance metadata. |
+| `AfterSOLBalance` | User or signer SOL balance after the transaction. |
+| `EntryContract` | Known router / entry contract account when detected. |
+| `Mayhem` / `Cashback` | Protocol or platform-specific labels detected from the transaction path. |
+
+Swap amount and slippage fields normalize instruction intent:
+
+| Field | Meaning |
+| --- | --- |
+| `SwapMode` | `exact_in`, `exact_out`, or empty when unknown. |
+| `FixedAmount` / `FixedAmountSide` / `FixedMint` | The user-specified fixed side of the swap. For `exact_in`, this is the input amount. For `exact_out`, this is the target output amount. |
+| `LimitAmountType` | `min_out` for `exact_in`, `max_in` for `exact_out`, or empty when unknown. |
+| `LimitAmount` / `LimitAmountSide` / `LimitMint` | User-specified limit on the opposite side. |
+| `ActualLimitAmount` / `ActualLimitAmountSide` | Actual executed amount on the limited side. |
+| `SlippageBps` | Remaining headroom to the user's limit in basis points. See `SLIPPAGE_MAPPING.md` for protocol-specific derivation rules. |
+
+Liquidity, migration, and DLMM-specific fields are populated only for protocols that expose them:
+
+| Field | Meaning |
+| --- | --- |
+| `Creator` | Creator account when exposed by pool or launch events. |
+| `MigrateToPool` / `MigrateTopProgram` | Destination pool and program for migration events. |
+| `LpMint` | LP token mint for liquidity operations when available. |
+| `ActiveBinId` / `StartBinId` / `EndBinId` | Meteora DLMM bin identifiers. |
+| `RemoveBp` | DLMM remove-liquidity basis points. |
+| `PositionAccount` | DLMM position account. |
+| `FeeAmount` / `LpFeeAmount` | Parsed fee amounts when the protocol exposes fee breakdowns. |
+| `FeeSide` / `FeeMint` / `FeeTokenProgram` / `FeeMintDecimals` | Fee side and mint metadata. |
+| `ConsumeUnit` | Per-swap compute unit value when available. |
+
+Amounts are normalized into decimals in parser output, but the exact scale depends on the source event and parser path. For persisted binary output, `tx_binary.go` defines the conversion rules and schema version.
+
+## Convert Transactions
+
+RPC transactions can be converted with `FromRpcTransactionWithMeta`:
+
+```go
+rawTx, err := pump_parser.FromRpcTransactionWithMeta(
+	txWithMeta,
+	blockTime,
+	slot,
+	indexWithinBlock,
+)
+```
+
+Yellowstone transactions can be converted with `ConvertYellowstoneGrpcTransactionToSolanaTransaction`:
+
+```go
+rawTx, err := pump_parser.ConvertYellowstoneGrpcTransactionToSolanaTransaction(
+	update,
+	createdUnix,
+)
+```
+
+Both conversion paths accept optional `RawTxConvertOptions`:
+
+```go
+rawTx, err := pump_parser.FromRpcTransactionWithMeta(
+	txWithMeta,
+	blockTime,
+	slot,
+	indexWithinBlock,
+	pump_parser.RawTxConvertOptions{
+		ParseLogEvents: true,
+	},
+)
+```
+
+`ParseLogEvents` attaches decoded program log events to matching instructions. `IgnoreLogMessages` skips log-message retention.
+
+## Binary Formats
+
+Parsed transaction binary:
+
+- `EncodeTxBinary` / `DecodeTxBinary` for one parsed `Tx`.
+- `EncodeTxsBinary` / `DecodeTxsBinary` for a batch of parsed `Tx`.
+- `DecodeTxsBinaryReader` for streaming `PTXS` reads.
+- `MergeTxsBinaryBytes` and `MergeTxsBinarySourcesToWriter` for merging `PTXS` batches.
+
+Raw transaction binary:
+
+- `EncodeRawTxBinary` / `DecodeRawTxBinary` for one `RawTx`.
+- `EncodeRawTxsBinary` / `DecodeRawTxsBinary` for a batch of `RawTx`.
+- `EncodeRawTxBlocksBinary` / `DecodeRawTxBlocksBinary` for grouped block data.
+- `DecodeRawTxsBinaryReader` for streaming `PRTS` reads.
+
+Format magic values:
+
+- `PTXB`: one parsed `Tx`.
+- `PTXS`: parsed `Tx` batch.
+- `PRTX`: one raw `RawTx`.
+- `PRTS`: raw `RawTx` batch.
+- `PRBS`: raw block-grouped `RawTx` batch.
+
+When adding or renaming transaction-facing enum values, update `tx_binary.go` enum tables by appending new values only. Reordering existing values changes persisted numeric IDs.
+
+## Commands
+
+Parse a live transaction by signature:
+
+```bash
+TX_HASH=<signature> go run ./cmd/rpc_parse
+```
+
+Collect Yellowstone transactions into a `.prbs` raw-block binary file:
+
+```bash
+YELLOWSTONE_X_TOKEN=<token> go run ./cmd/collect_yellowstone_rawtx_binary \
+  -endpoint ams.rpc.orbitflare.com:10000 \
+  -duration 5m \
+  -output testdata/rawtx-binary/sample.prbs
+```
+
+Measure parsed `Tx` binary size from a `getBlock` JSON payload:
+
+```bash
+go run ./cmd/measure_tx_binary_block \
+  -file /path/to/block.json \
+  -slot 413539056 \
+  -swaps-only
+```
+
+Analyze raw transaction binary size distribution:
+
+```bash
+go run ./cmd/analyze_rawtx_binary_size \
+  -file testdata/rawtx-binary/sample.prbs
+```
+
+## Development
+
+Run the full test suite:
+
+```bash
+go test ./...
+```
+
+Useful focused checks:
+
+```bash
+go test -run 'TestTxBinary|TestRawTxBinary' .
+go test -run 'TestMetaoraPoolSwapEventFromLogsUsesMatchingInvocation|TestMetaoraPoolSwapInstructionOccurrenceIncludesInnerInstructions|TestAttachLogEventsToInstructions' .
+TX_HASH=<signature> go run ./cmd/rpc_parse
+```
+
+For parser regressions, reproduce with the exact transaction signature first, then add a targeted unit test or fixture around the corrected parser path.

+# Slippage Mapping
+
+This document describes how `SlippageBps` is derived for each supported swap protocol in this repository.
+
+## Unified Fields
+
+Each parsed `Swap` may include these normalized fields:
+
+- `SwapMode`
+- `FixedAmount`
+- `FixedAmountSide`
+- `FixedMint`
+- `LimitAmountType`
+- `LimitAmount`
+- `LimitAmountSide`
+- `LimitMint`
+- `ActualLimitAmount`
+- `ActualLimitAmountSide`
+- `SlippageBps`
+
+## Internal Enum Mapping
+
+These fields are stored internally as `uint8` enums and serialized as strings in JSON / debug output.
+
+### `SwapMode`
+
+| Raw Value | Name | Serialized Value |
+| --- | --- | --- |
+| `0` | `SwapModeUnknown` | `""` |
+| `1` | `SwapModeExactIn` | `"exact_in"` |
+| `2` | `SwapModeExactOut` | `"exact_out"` |
+
+### `SwapAmountSide`
+
+Used by:
+
+- `FixedAmountSide`
+- `LimitAmountSide`
+- `ActualLimitAmountSide`
+
+| Raw Value | Name | Serialized Value |
+| --- | --- | --- |
+| `0` | `SwapAmountSideUnknown` | `""` |
+| `1` | `SwapAmountSideBase` | `"base"` |
+| `2` | `SwapAmountSideQuote` | `"quote"` |
+
+### `SwapLimitType`
+
+Used by:
+
+- `LimitAmountType`
+
+| Raw Value | Name | Serialized Value |
+| --- | --- | --- |
+| `0` | `SwapLimitTypeUnknown` | `""` |
+| `1` | `SwapLimitTypeMinOut` | `"min_out"` |
+| `2` | `SwapLimitTypeMaxIn` | `"max_in"` |
+
+## Calculation Rules
+
+- `exact_in`
+  - `SlippageBps = (actual_out - min_out) / actual_out * 10000`
+- `exact_out`
+  - `SlippageBps = (max_in - actual_in) / max_in * 10000`
+
+Interpretation:
+
+- Positive: execution is better than the user limit
+- Zero: execution lands exactly on the user limit
+- `10000`: user limit is effectively unbounded on the constrained side (for example `min_out = 0`)
+- Negative raw headroom is clamped to `0` because successful-swap storage uses a non-negative bounded metric
+
+This definition makes `SlippageBps` a bounded "remaining headroom to the user's limit" metric for successful swaps:
+
+- `exact_in`: how much output headroom remained, measured against the realized output
+- `exact_out`: how much input headroom remained, measured against the allowed max input
+
+## Protocol Mapping

+| `Pump` | `sell` | `exact_in` | token in | `min_out` | min SOL out | actual SOL out |
+| `PumpAMM` | `buy` | `exact_out` | target base out | `max_in` | max quote in | actual quote in |
+| `PumpAMM` | `buy_exact_quote_in` | `exact_in` | quote in | `min_out` | min base out | actual base out |

+| `MeteoraDLMM` | `swap` / `swap2` / `swap_with_price_impact` | `exact_in` | `AmountIn` | `min_out` | instruction min out | event output |
+| `MeteoraDLMM` | `swap_exact_out` / `swap_exact_out2` | `exact_out` | `OutAmount` | `max_in` | `MaxInAmount` | event input |
+| `MeteoraPools` | `swap` | `exact_in` | `InAmount` | `min_out` | `MinimumOutAmount` | actual output side |
+| `MeteoraBondingCurve` | `swap` / `swap2` | `exact_in` | `AmountIn` | `min_out` | `MinimumAmountOut` | actual output side |
+| `MeteoraAmmV2` | `swap` / `swap2` exact-in or partial | `exact_in` | params input side | `min_out` | params output threshold | actual output side |
+| `MeteoraAmmV2` | `swap` / `swap2` exact-out | `exact_out` | params target output | `max_in` | params max input | actual input side |
+| `RaydiumLaunchLab` | `*_ExactIn` | `exact_in` | `Amount` | `min_out` | `OtherAmountThreshold` | actual output side |
+| `RaydiumLaunchLab` | `*_ExactOut` | `exact_out` | `Amount` | `max_in` | `OtherAmountThreshold` | actual input side |

+| `RaydiumCPMM` | `swap_base_output` | `exact_out` | `AmountOut` | `max_in` | `MaxAmountIn` | actual input side |
+| `RaydiumCLMM` | `swap` / `swap_v2` | `exact_in` or `exact_out` | `amount` | `min_out` or `max_in` | `other_amount_threshold` | opposite-side actual amount |
+| `RaydiumV4` | `swap_base_in` / `swap_base_in_v2` | `exact_in` | `amount_in` | `min_out` | `minimum_amount_out` | actual output side |
+| `RaydiumV4` | `swap_base_out` / `swap_base_out_v2` | `exact_out` | `amount_out` | `max_in` | `max_amount_in` | actual input side |
+| `OrcaWhirlpool` | `swap` / `swap_v2` | `exact_in` or `exact_out` | `amount` | `min_out` or `max_in` | `other_amount_threshold` | opposite-side actual amount |
+| `OrcaWhirlpool` | `two_hop_swap` / `two_hop_swap_v2` | route-level | route specified amount | `min_out` or `max_in` | route threshold | route final output or total input |
+
+## Notes
+
+- `Pump` quote side is normalized to `wSOL` in the slippage fields, even when legacy `Swap.QuoteMint` is not populated.
+- `OrcaWhirlpool` two-hop instructions use route-level slippage. The normalized slippage fields are attached to the first returned swap entry.
+- `MeteoraAmmV2` uses `SwapMode.ExactIn`, `SwapMode.PartialFill`, and `SwapMode.ExactOut`. `PartialFill` is treated like exact-in for slippage purposes because it still uses a minimum-output threshold.
+
+## DAMM v2 Verification
+
+The `MeteoraAmmV2` mapping has been checked against the program IDL for `cpamdpZCGKUy5JxQXB4dcpGPiikHawvSWAd6mEn1sGG`.
+
+- `swap`
+  - instruction arg type: `SwapParameters`
+  - fields: `amountIn`, `minimumAmountOut`
+  - semantics: exact-in
+- `swap2`:
+  - instruction / event arg type: `SwapParameters2`
+  - `amount0`: "When it's exact in, partial fill, this will be amount_in. When it's exact out, this will be amount_out"
+  - `amount1`: "When it's exact in, partial fill, this will be minimum_amount_out. When it's exact out, this will be maximum_amount_in"
+  - `swapMode`: `ExactIn`, `PartialFill`, `ExactOut`
+
+The downloaded JSON IDL references `SwapMode` in the field docs but does not inline the enum body itself. In this repository, the raw `swapMode` values are interpreted consistently as:
+
+- `0 = ExactIn`
+- `1 = PartialFill`
+- `2 = ExactOut`
+
+That means the parser mapping is:
+
+- `swap2` + `ExactIn` / `PartialFill`
+  - `FixedAmount = amount0`
+  - `LimitAmount = amount1`
+  - `LimitAmountType = min_out`
+- `swap2` + `ExactOut`
+  - `FixedAmount = amount0`
+  - `LimitAmount = amount1`
+  - `LimitAmountType = max_in`

+
+## Tx Binary enum synchronization
+
+When adding or renaming transaction-facing enum values, keep the binary format definitions in sync.
+
+This includes, but is not limited to:
+
+- tx events
+- programs
+- platforms
+- MEV agents
+- swap modes, amount sides, limit types, and fee sides
+
+Checklist:
+
+1. Add the public constant in the normal source location, such as `enum.go`.
+2. Add any address mapping in `consts.go` when the enum is account-derived, such as platform or MEV agent detection.
+3. Append the new value to the matching versioned enum list in `tx_binary.go` under `txBinaryEnumTables`.
+4. Do not reorder or insert into existing `tx_binary.go` enum lists unless the binary version is intentionally changed; append to preserve existing numeric IDs.
+5. Add or update tx-binary round-trip coverage so encoding and decoding the new enum value is exercised.
