Quick Start

Build the WASM binary:

make build-neg-risk
# or
cd polymarket-neg-risk-ctf && substreams build

Create the Substreams package:

make package-neg-risk
# or
cd polymarket-neg-risk-ctf && substreams pack

Run the Substreams:

make run-neg-risk
# or
substreams run substreams.yaml map_all_events \
  --network polygon \
  --start-block -1000

Event Types

The package extracts the following V2 event categories:

Trading Events

OrderFilled - Order filled (with side uint8, token_id, builder, metadata)
OrdersMatched - Orders matched (with side uint8, token_id)

Fee Events

FeeCharged - Protocol fee collected (recipient, amount)
FeeReceiverUpdated - Fee receiver address changed
MaxFeeRateUpdated - Maximum fee rate changed

Admin Events

NewAdmin - New admin added
NewOperator - New operator added
RemovedAdmin - Admin removed
RemovedOperator - Operator removed

Pause Events

UserPaused - User paused from trading
UserUnpaused - User unpaused
UserPauseBlockIntervalUpdated - Pause interval changed

Order Approval Events

OrderPreapproved - Order preapproved
OrderPreapprovalInvalidated - Order preapproval invalidated

// `Any` contains an arbitrary serialized protocol buffer message along with a URL that describes the type of the serialized message. Protobuf library provides support to pack/unpack Any values in the form of utility functions or additional generated methods of the Any type. Example 1: Pack and unpack a message in C++. Foo foo = ...; Any any; any.PackFrom(foo); ... if (any.UnpackTo(&foo)) { ... } Example 2: Pack and unpack a message in Java. Foo foo = ...; Any any = Any.pack(foo); ... if (any.is(Foo.class)) { foo = any.unpack(Foo.class); } Example 3: Pack and unpack a message in Python. foo = Foo(...) any = Any() any.Pack(foo) ... if any.Is(Foo.DESCRIPTOR): any.Unpack(foo) ... Example 4: Pack and unpack a message in Go foo := &pb.Foo{...} any, err := anypb.New(foo) if err != nil { ... } ... foo := &pb.Foo{} if err := any.UnmarshalTo(foo); err != nil { ... } The pack methods provided by protobuf library will by default use 'type.googleapis.com/full.type.name' as the type URL and the unpack methods only use the fully qualified type name after the last '/' in the type URL, for example "foo.bar.com/x/y.z" will yield type name "y.z". JSON The JSON representation of an `Any` value uses the regular representation of the deserialized, embedded message, with an additional field `@type` which contains the type URL. Example: package google.profile; message Person { string first_name = 1; string last_name = 2; } { "@type": "type.googleapis.com/google.profile.Person", "firstName": <string>, "lastName": <string> } If the embedded message type is well-known and has a custom JSON representation, that representation will be embedded adding a field `value` which holds the custom JSON in addition to the `@type` field. Example (for message [google.protobuf.Duration][]): { "@type": "type.googleapis.com/google.protobuf.Duration", "value": "1.212s" }

message Any {

optional string = 1;

optional bytes = 2;

}
