Binance Schemas

Binance Schemas

The @tundraconnect/binance/schemas subpath exports Guardian validators and inferred types for the stream payloads (event.data).

import { BinanceTradeSchemaObject } from '@tundraconnect/binance/schemas';

declare const payload: unknown;
const [error, trade] = BinanceTradeSchemaObject.safeParse(payload);

Binance's single-letter keys are case-sensitive (e/E, t/T, b/B, m/M), so each schema renames exactly the documented ones and passes every other key through untouched (the trade's M, for one, stays M). Decimal strings become numbers; ids and timestamps must already be numbers.

Schema	Stream	Fields
BinanceTradeSchemaObject	<symbol>@trade	eventTime, symbol, tradeId, price, quantity, tradeTime, buyerIsMaker
BinanceBookTickerSchemaObject	<symbol>@bookTicker	updateId, symbol, bidPrice, bidQuantity, askPrice, askQuantity
BinanceDepthUpdateSchemaObject	<symbol>@depth@100ms	eventTime, symbol, firstUpdateId, finalUpdateId, bids/asks as { price, quantity }

buyerIsMaker: true means the buyer was the resting order — the taker sold.
