Drift Gateway

Self hosted API gateway to easily interact with Drift V2 Protocol

Build & Run

⚠️ Before starting, ensure a Drift user account is initialized e.g. via the drift app at https://beta.drift.trade (devnet) or https://app.drift.trade

# build
cargo build --release

# configure the gateway signing key
export DRIFT_GATEWAY_KEY=</PATH/TO/KEY.json | seedBase58>

# '--dev' to toggle devnet markets (default is mainnet)
# ensure the RPC node is also using the matching devnet or mainnet
drift-gateway --dev https://api.devnet.solana.com

# or mainnet
# NB: `api.mainnet-beta.solana.com` cannot be used due to rate limits on certain RPC calls
drift-gateway https://rpc-provider.example.com

Place Orders

• use sub-zero amount to indicate sell/offer order
• userOrderId is a uint in the range 1 <= x <= 255 which can be assigned by the client to help distinguish orders
• orderType only "limit" and "market" options are fully supported by the gateway
• oraclePriceOffset supported on "limit" order types. It creates a limit order with a floating price relative to the market oracle price. when supplied the price field is ignored.
• maxTs order expiration timestamp. NB: expired orders can incur protocol costs

$ curl localhost:8080/v2/orders -X POST \
-H 'content-type: application/json' \
-d '{
    "orders": [
    {
        "marketIndex": 1,
        "marketType": "spot",
        "amount": -1.23,
        "price": 80.0,
        "postOnly": true,
        "orderType": "limit",
        "userOrderId": 101,
        "reduceOnly": false,
        "maxTs": 1707112301
    },
    {
        "marketIndex": 0,
        "marketType": "perp",
        "amount": 1.23,
        "postOnly": true,
        "orderType": "limit",
        "oraclePriceOffset": 2,
        "userOrderId": 102
    }]
}'

Returns solana tx signature on success

Modify Orders

like place orders but caller must use either orderId or userOrderId to indicate which order(s) to modify.

• amount can be modified to flip the order from long/short to bid/ask
• the order market cannot be modified.

$ curl localhost:8080/v2/orders -X PATCH \
-H 'content-type: application/json' \
-d '{
    "orders": [{
        "marketIndex": 0,
        "marketType": "perp",
        "amount": -1.1,
        "price": 80.5,
        "userOrderId": 101
    },
    {
        "marketIndex": 1,
        "marketType": "spot",
        "amount": 2.05,
        "price": 61.0,
        "userOrderId": 32
    }]
}'

Returns solana tx signature on success

Cancel Orders

# cancel all by market id
$ curl localhost:8080/v2/orders -X DELETE -H 'content-type: application/json' -d '{"marketIndex":1,"marketType":"spot"}}'
# cancel by order ids
$ curl localhost:8080/v2/orders -X DELETE -H 'content-type: application/json' -d '{"ids":[1,2,3,4]}'
# cancel by user assigned order ids
$ curl localhost:8080/v2/orders -X DELETE -H 'content-type: application/json' -d '{"userIds":[1,2,3,4]}'
# cancel all orders
$ curl localhost:8080/v2/orders -X DELETE

Returns solana tx signature on success

Atomic Cancel/Modify/Place Orders

Atomically cancel, modify, and place orders without possible downtime. Request format is an embedded cancel modify, and place request

$ curl localhost:8080/v2/orders/cancelAndPlace -X POST -H 'content-type: application/json' \
-d '{
    "cancel": {
        "marketIndex": 0,
        "marketType": "perp"
    },
    "modify": {
      "orders": [{
            "marketIndex": 0,
            "marketType": "perp",
            "orderId": 555,
            "amount": -0.5,
            "price": 82.0
      }]
    },
    "place": {
        "orders": [
        {
            "marketIndex": 0,

            "price": 99.0,
            "postOnly": true,
            "orderType": "limit",
            "reduceOnly": false
        }]
    }
}'

Get SOL balance

Return the SOL balance of the transaction signer

$ curl localhost:8080/v2/balance

WebSockets

Websocket API is provided for live event streams by default at port 127.0.0.1:1337

Subscribing

Subscribe to order and fills updates by a subAccountId (0 is the drift default)

{"method":"subscribe", "subAccountId":0}
// unsubscribe
{"method":"unsubscribe", "subAccountId":0}

Event Payloads

event payloads can be distinguished by "channel" field and the "data" payload is keyed by the event type

order cancelled

    "data": {
        "orderCancel": {
            "orderId": 156,
            "ts": 1704777451,

        }
    },
    "channel": "fills",
    "subAccountId": 0
}

order modify

Modifying an order produces a cancel event followed by a create event with the same orderId

order cancel (missing) | experimental

emitted when a cancel action was requested on an order that did not exist onchain.

this event may be safely ignored, it is added in an effort to help order life-cycle tracking in certain setups.

• one of userOrderId or orderId will be a non-zero value (dependent on the original tx).

{
    "data": {
        "orderCancelMissing": {
            "userOrderId": 5,
            "orderId": 0,
            "ts": 1704777451,
            "signature": "2Cdo5Xgxj6uWY6dnWmuU5a8tH5fKC2K6YUqzVYKgnm8KkMVhPczBZrNEs4VGwEBMhgosifmNjBXSjFMWbGKJiqSz"
        }
    },
    "channel": "orders",
    "subAccountId": 0
}

funding payment

settled funding payment event for open perp positions

• amount is usdc

{
    "data": {
        "fundingPayment": {
            "amount": "0.005558",
            "marketIndex": 0,
            "ts": 1708664443
        }
    },
    "channel": "funding",
    "subAccountId": 0
}

Emulation Mode

Passing the --emulate <EMULATED_PUBBKEY> flag will instruct the gateway to run in read-only mode.

The gateway will receive all events, positions, etc. as normal but be unable to send transactions.

note therefore DRIFT_GATEWAY_KEY is not required to be set.

Delegated Signing Mode

Passing the --delegate <DELEGATOR_PUBKEY> flag will instruct the gateway to run in delegated signing mode.

In this mode, the gateway will act for DELEGATOR_PUBKEY and sub-accounts while signing with the key provided via DRIFT_GATEWAY_KEY (i.e delegate key).

Use the drift UI or Ts/Python SDK to assign a delegator key. see Delegated Accounts for more information.

Sub-account Switching

By default the gateway uses the drift sub-account (index 0)

A subAccountId URL query parameter may be supplied to switch the sub-account per request basis.

e.g http://<gateway>/v1/orders?subAccountId=3 will return orders for the wallet's sub-account 3

Errors

error responses have the following JSON structure:

{
    "code": "<http status code | program error code>",
    "reason": "<explanation>"
}

Some endpoints send transactions to the drift program and can return program error codes. The full list of drift program error codes is available in the API docs

Common Errors

AccountNotFound usually means the drift user (sub)account has not been initialized. Use the UI or Ts/Python sdk to initialize the sub-account first.

{
  "code": 500,
  "reason": "AccountNotFound: pubkey=FQHZg9yU2o5uN9ERQyeTNNAMe3JWf13gce2DUj6x2HTv"
}

The free _api.mainnet-beta.solana.com_RPC cannot be used due to rate-limits on getProgramAccounts calls
