Connect at `wss://.mainnet.rpcpool.com/`. {% hint style="info" %} The WebSocket service runs on Whirligig, Triton's WebSocket server for Dragon's Mouth gRPC. Usage pages and invoices list WebSocket traffic as Whirligig. The older `/whirligig` path reaches the same service. {% endhint %} ## Use cases * **Real-time browser apps and browser extensions.** Browsers don't support gRPC. Subscribe over `wss://` with the standard Solana WebSocket API. * **Backends.** If you can run a gRPC client, use [Dragon's Mouth](/solana/real-time-streaming/dragon-s-mouth-grpc.md). If your backend already uses a Solana WebSocket client, use the WebSocket API. ## Features
:bolt: transactionSubscribeA full-transaction subscription, a Triton extension, with account include, exclude, and required filters.
:gauge-high: Intra-slot updatesAt processed commitment, accountSubscribe and programSubscribe notify on every account write as the stream delivers it, within the slot.
:code: jsonParsed encodingaccountSubscribe and programSubscribe return structured objects for parsable programs instead of raw byte arrays, with resolved mint metadata on token accounts.
:cube: blockSubscribeNew blocks over wss://. Needs confirmed or finalized commitment.
## How it works The WebSocket server reads a Dragon's Mouth gRPC stream, matches the updates to each client's subscriptions, and sends them as standard Solana WebSocket notifications. ```mermaid %%{init: {'theme':'base','themeVariables':{'primaryColor':'#F2EDF6','primaryBorderColor':'#7A4BA0','primaryTextColor':'#171717','lineColor':'#956FB3','secondaryColor':'#E4DBEC','tertiaryColor':'#D7C9E3','edgeLabelBackground':'#F2EDF6'},'flowchart':{'nodeSpacing':20,'rankSpacing':35,'curve':'linear'}}}%% flowchart LR dm["Dragon's Mouth

Parameters and results are in [WebSocket methods](/solana/rpc-methods/real-time-streaming/whirligig-websocket.md), except for `rootSubscribe`, `voteSubscribe`, and `slotsUpdatesSubscribe`, which have no reference page. | Method | Returns | | ----------------------- | ---------------------------------------------------------------------------------- | | `accountSubscribe` | An account's data, on change | | `blockSubscribe` | New blocks | | `logsSubscribe` | Transaction logs mentioning an address | | `programSubscribe` | Accounts owned by a program, on change | | `signatureSubscribe` | A signature's confirmation status | | `slotSubscribe` | Each new slot | | `rootSubscribe` | Each new root (the highest finalized slot) | | `voteSubscribe` | Votes from committed vote transactions (none on Alpenglow; unstable Solana method) | | `slotsUpdatesSubscribe` | Detailed slot-status updates (unstable Solana method) | | `transactionSubscribe` | Full transactions matching a filter. Triton extension to the Solana WebSocket API | Each subscribe method returns a subscription `id` and has a matching unsubscribe (see [Unsubscribe](#unsubscribe)). ## Connection options {% tabs %} {% tab title="JavaScript (web3.js)" %} Set `wsEndpoint` to your `wss://` endpoint URL. Standard Solana WebSocket clients usually need no other change. ```javascript import { Connection, PublicKey } from "@solana/web3.js"; const connection = new Connection( "https://.mainnet.rpcpool.com/", { wsEndpoint: "wss://.mainnet.rpcpool.com/", commitment: "processed", } ); const subscriptionId = connection.onAccountChange( new PublicKey(""), (accountInfo, context) => { console.log("slot:", context.slot, "lamports:", accountInfo.lamports); }, "processed" ); // When done: // await connection.removeAccountChangeListener(subscriptionId); ``` {% endtab %} {% tab title="Rust" %} Uses the standard [`solana-pubsub-client`](https://docs.rs/solana-pubsub-client) crate. {% code title="Cargo.toml" %} ```toml [dependencies] solana-pubsub-client = "~4.4" solana-rpc-client-types = "~4.4" solana-account-decoder-client-types = "~4.4" solana-pubkey = "4" solana-commitment-config = "3" tokio = { version = "1", features = ["full"] } futures = "0.3" serde_json = "1" rustls = { version = "0.23", default-features = false, features = ["ring"] } # TLS crypto provider for wss:// ``` {% endcode %} {% code title="src/main.rs" %} ```rust use futures::StreamExt; use solana_account_decoder_client_types::UiAccountEncoding; use solana_commitment_config::CommitmentConfig; use solana_pubkey::Pubkey; use solana_pubsub_client::nonblocking::pubsub_client::PubsubClient; use solana_rpc_client_types::config::RpcAccountInfoConfig; use std::str::FromStr; #[tokio::main] async fn main() { let client = PubsubClient::new("wss://.mainnet.rpcpool.com/") .await .expect("connect"); let pubkey = Pubkey::from_str("").expect("valid pubkey"); let config = RpcAccountInfoConfig { encoding: Some(UiAccountEncoding::JsonParsed), commitment: Some(CommitmentConfig::processed()), data_slice: None, min_context_slot: None, }; let (mut stream, unsubscribe) = client .account_subscribe(&pubkey, Some(config)) .await .expect("subscribe"); while let Some(update) = stream.next().await { println!("{}", serde_json::to_string(&update).unwrap()); } drop(stream); drop(unsubscribe); client.shutdown().await.expect("shutdown"); } ``` {% endcode %} {% endtab %} {% tab title="JavaScript (raw WebSocket)" %} Required for `transactionSubscribe`, which returns full transaction data in a single call and is not available in `@solana/web3.js`. ```javascript const ws = new WebSocket("wss://.mainnet.rpcpool.com/"); ws.addEventListener("open", () => { // Keep alive: idle connections are closed after 60 s setInterval(() => ws.send(JSON.stringify({ jsonrpc: "2.0", method: "ping" })), 30_000); ws.send(JSON.stringify({ jsonrpc: "2.0", id: 1, method: "transactionSubscribe", params: [ { vote: false, failed: false }, { commitment: "processed", encoding: "jsonParsed", transactionDetails: "full", maxSupportedTransactionVersion: 1, }, ], })); }); ws.addEventListener("message", ({ data }) => { const msg = JSON.parse(data); if (msg.method === "transactionNotification") { console.log("tx:", msg.params.result.value.transaction.transaction.signatures[0]); } }); ``` {% endtab %} {% endtabs %} {% hint style="info" %} Connections idle for over 60 seconds are closed, so keep them alive by sending `{"jsonrpc":"2.0","method":"ping"}`. {% endhint %} Run your client close to a Triton region to lower latency. ### Commitment levels Set the commitment level per subscription in the `config` argument. `blockSubscribe` accepts `confirmed` or `finalized`, not `processed`. | Level | Meaning | Update sent | | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | -------------------------------------- | | `processed` | The node has processed the transaction or account write; its slot can still be in progress. Not yet `confirmed` or `finalized`; the block can still be skipped by the cluster. | Without waiting for its slot to finish | | `confirmed` | The highest slot voted on by a supermajority of the cluster. On Alpenglow, `confirmed` and `finalized` updates arrive together. | After its slot reaches `confirmed` | | `finalized` | The highest slot that is final. On Alpenglow, a block becomes final about 150 ms after the leader proposes it. | After its slot reaches `finalized` | The WebSocket server subscribes to Dragon's Mouth at `processed`. {% hint style="info" %} For the lowest latency, subscribe at `processed` and track `confirmed` and `finalized` yourself. `slotsUpdatesSubscribe` sends `optimisticConfirmation` when a slot is confirmed and `root` when it is finalized. {% endhint %} ## Subscribe request ### accountSubscribe {% tabs %} {% tab title="Request" %} ```json { "jsonrpc": "2.0", "id": 1, "method": "accountSubscribe", "params": [

"result": 42, "id": 1 } ``` Pass that `id` to the matching unsubscribe method (`accountUnsubscribe`, `slotUnsubscribe`, and so on): ```json { "id": 1, "jsonrpc": "2.0", "method": "slotUnsubscribe", "params": [42] } ``` The result is `true` if the subscription was active and removed: ```json { "jsonrpc": "2.0", "result": true, "id": 1 } ``` An `id` that does not exist on the connection returns error `-32602`, `Invalid subscription id.` ## Client You can find a reference CLI client on GitHub: [WebSocket CLI client](https://github.com/rpcpool/yellowstone-whirligig-client). ## Pricing WebSocket traffic is billed by the bandwidth it streams, on shared and dedicated endpoints. By default, a dedicated endpoint's WebSocket connections are served by Triton's shared servers, not by your node. See the [pricing page](https://triton.one/pricing). WebSocket frames are not compressed (no `permessage-deflate`). To stream less: * Filter your subscriptions: `filters` on `programSubscribe`, account filters on `transactionSubscribe`. * Use the `base64+zstd` encoding when bandwidth is limited, not by default. It compresses the account data field, not the whole message, and costs CPU on the server and on your client. ## What's next
