## Release notes

### v0.5.6

- Adds Meteora DBC log parsing with program-context routing and filter parity.

- Adds Raydium CLMM/CPMM and Orca account parsers and exports.

- Fixes default no-filter RPC/Yellowstone instruction parsing so it no longer behaves like an empty include-only filter.

- Merges RPC ALT loaded writable/readonly keys into the full instruction account table.

- Skips ShredStream/RPC instruction parsing early for account-only or empty include-only filters.

### v0.5.5

- Aligns ShredStream parsing with Rust/Node.js/Go for low-latency static-account paths.

- Uses default pubkey placeholders for V0 ALT-loaded instruction accounts instead of dropping the instruction.

- Adds discriminator fallback when the ShredStream outer program id is ALT-loaded.

- Fixes Pump.fun ShredStream create/create_v2 fallback to use instruction-order accounts.

- Improves Pump.fun v2 short-account parsing, event-type filtering, and multi-protocol routing parity.

## How to use

### 1. Install

**From PyPI**

```bash

pip install sol-parser-sdk-python==0.5.6

```

**From source**

```bash

git clone https://github.com/0xfnzero/sol-parser-sdk-python

cd sol-parser-sdk-python

pip install -e .

pip install grpcio grpcio-tools protobuf base58 python-dotenv

```

### 2. Environment (Yellowstone gRPC examples)

At the **package root** (next to `pyproject.toml`):

```bash

cp .env.example .env

# Set GRPC_URL (or GRPC_ENDPOINT) and GRPC_AUTH_TOKEN or GRPC_TOKEN

```

Run examples from that directory so `.env` is picked up (same idea as the Node.js package).

**CLI overrides:** `--grpc-url` / `-g`, `--grpc-token` / `--token` (also `--grpc-url=https://host:443`). **Rust-compatible names:** `GRPC_AUTH_TOKEN` (same as [sol-parser-sdk](https://github.com/0xfnzero/sol-parser-sdk) examples), `GRPC_ENDPOINT` (alias for URL). **Legacy env:** `GEYSER_ENDPOINT` / `GEYSER_API_TOKEN`. **Precedence:** CLI > `GRPC_URL` / `GRPC_ENDPOINT` > `GEYSER_*` > defaults; token: CLI > `GRPC_AUTH_TOKEN` > `GRPC_TOKEN` > `GEYSER_API_TOKEN`. Explicit shell `export` wins over `.env`; `python-dotenv` does not overwrite existing variables.

Helpers: `sol_parser.env_config` (`parse_grpc_credentials`, `require_grpc_env`, `parse_shredstream_url`, …), re-exported from `sol_parser`.

### 3. Smoke test

```bash

python examples/pumpfun_quick_test.py

```

Requires `GRPC_URL` (or `GRPC_ENDPOINT`) and (for most providers) `GRPC_AUTH_TOKEN` or `GRPC_TOKEN` in `.env` or the environment. You can pass credentials on the command line instead; see step 2.

### 4. Minimal gRPC subscribe + parse

```python

import asyncio

import os

import base58

from sol_parser import parse_logs_only

from sol_parser.grpc_client import YellowstoneGrpc

from sol_parser.grpc_types import Protocol, SubscribeCallbacks, transaction_filter_for_protocols

async def main():

    endpoint = (

        os.environ.get("GRPC_URL", "").strip()

        or os.environ.get("GRPC_ENDPOINT", "").strip()

        or os.environ.get("GEYSER_ENDPOINT", "solana-yellowstone-grpc.publicnode.com:443")

    )

    token = (

        os.environ.get("GRPC_AUTH_TOKEN", "").strip()

        or os.environ.get("GRPC_TOKEN", "").strip()

        or os.environ.get("GEYSER_API_TOKEN", "")

    )

    client = YellowstoneGrpc(endpoint)

    if token:

        client.set_x_token(token)

    await client.connect()

    filter_ = transaction_filter_for_protocols([Protocol.PUMP_FUN, Protocol.PUMP_SWAP])

    filter_.vote = False

    filter_.failed = False

    def on_update(update):

        if update.transaction is None or update.transaction.transaction is None:

            return

        tx_info = update.transaction.transaction

        slot = update.transaction.slot

        logs = tx_info.log_messages

        if not logs:

            return

        sb = bytes(tx_info.signature) if tx_info.signature else b""

        sig = base58.b58encode(sb).decode("ascii") if len(sb) == 64 else ""

        events = parse_logs_only(

            logs, sig, slot, None, subscribe_tx_info=tx_info

        )  # tx_info from gRPC update — fills accounts from instruction keys

        for ev in events:

            print(ev)

    sub = await client.subscribe_transactions(

        filter_,

        SubscribeCallbacks(on_update=on_update, on_error=print, on_end=lambda: None),

    )

    print("subscribed", sub.id)

    try:

        await asyncio.Event().wait()

    except KeyboardInterrupt:

        pass

    await client.disconnect()

asyncio.run(main())

```

**Lighter path:** `parse_logs_only(logs, …)` only needs log messages from the update (no full wire transaction).

### 5. ShredStream (HTTP — not Yellowstone gRPC)

Python includes a native ShredStream client (`ShredStreamClient`, `ShredStreamConfig`) plus the same env/CLI helpers as Node (`parse_shredstream_url`: `SHREDSTREAM_URL` / `SHRED_URL`, `--url` / `-u` / `--endpoint=`). Install the optional extra with `pip install 'sol-parser-sdk-python[shredstream]'`. ShredStream uses its own endpoint, **not** `GRPC_URL`.

The Python ShredStream hot path uses static account keys only. V0 ALT-loaded instruction accounts are represented with default pubkey placeholders, and ALT-loaded outer program ids are parsed best-effort by discriminator. Inner CPI/log-only events still require the Yellowstone/RPC paths.

## Examples

From the **package root** after `pip install -e .`. Run with `python examples/.py`. Scripts are written to mirror the **output layout and env names** of [sol-parser-sdk/examples](https://github.com/0xfnzero/sol-parser-sdk/tree/main/examples) (Rust); streaming uses `subscribe_transactions` + `parse_logs_only` with the same program IDs as `TransactionFilter::for_protocols` in Rust.

**Env:** gRPC examples need **`GRPC_URL`** or **`GRPC_ENDPOINT`**, plus **`GRPC_AUTH_TOKEN`** or **`GRPC_TOKEN`** (or legacy `GEYSER_*`). See **`.env.example`**.

---

## Protocols

PumpFun, PumpSwap, Raydium AMM V4 / CLMM / CPMM, Orca Whirlpool, Meteora DAMM V2 / DLMM, Raydium LaunchLab (see `sol_parser/`).

---

## Useful exports

- `parse_logs_only` — log-based DEX events from gRPC log messages.

- `format_dex_event_json` / `dex_event_to_jsonable` — pretty-print `DexEvent` as indented JSON (one field per line); `repr(ev)` is the default dataclass single-line form, not JSON.

- `YellowstoneGrpc` — async Yellowstone gRPC client (`connect`, `subscribe_transactions`, `disconnect`).

- `now_micros` — microsecond clock (same role as Rust `sol_parser_sdk::core::now_micros`).

- `transaction_filter_for_protocols` / `program_ids_for_protocols` / `account_filter_for_protocols` — same program IDs as Rust `Protocol` + `for_protocols` in `grpc/filter.rs`.

- `parse_grpc_credentials` / `require_grpc_env` — load `.env` + env + CLI (aligned with [sol-parser-sdk-nodejs](https://github.com/0xfnzero/sol-parser-sdk-nodejs) `grpc_env`).

---

## Advanced

### Custom gRPC endpoint

```python

import os

from sol_parser.grpc_client import YellowstoneGrpc

endpoint = os.environ.get("GRPC_URL") or os.environ.get("GRPC_ENDPOINT") or os.environ.get(

    "GEYSER_ENDPOINT", "solana-yellowstone-grpc.publicnode.com:443"

)

token = (

    os.environ.get("GRPC_AUTH_TOKEN")

    or os.environ.get("GRPC_TOKEN")

    or os.environ.get("GEYSER_API_TOKEN", "")

)

client = YellowstoneGrpc(endpoint)

if token:

    client.set_x_token(token)

```

### Create + buy detection

`parse_logs_only` can detect create-and-buy patterns from program logs; see the PumpFun examples.
