StreamBuilderFills - Stream Builder Fills
Subscribe to live Hyperliquid fills attributed to one builder, optionally scoped by coin, over the V3 gRPC API.
StreamBuilderFills sends live fills whose nested builder.address equals the requested builder. Fills without builder attribution never match.
Request and live-only behavior
builder is a required 0x-prefixed address and matches case-insensitively. The zero address has no special meaning. Empty coins selects every coin; supplied coin names match exactly and unknown names simply never match.
The stream has no opening snapshot or backfill. A source block can still emit an empty fills list after filtering so that sequence remains contiguous.
Sequencing and recovery
Require contiguous sequence values. A gap or ABORTED means live frames were lost; reconnect and use StreamFills or historical data for the missing interval. See the gRPC overview for shared errors.
