What's new

Launches, new assets, bridge routes and developer tools. Every item links to where you can check it.

AssetsStock tracker prices around the clock

Stock and ETF tracker prices now update outside the US session too. 195 of 221 tickers move after hours and at weekends: 133 from equity perpetual markets (Binance, Hyperliquid HIP-3, Bitget, Gate, MEXC, Bybit, OKX) and Robinhood extended hours, 40 from a same-index or same-sector reference (for example GOOG from GOOGL, IVV from SPY, ITUB from EWZ) and 22 ADRs from their home listing times the FX rate. The other 26 keep their last close until the US session opens. Every off-hours price passes a volume floor, a spread filter and a maximum move from the last close; if a source fails, the token keeps its last US close until a valid source returns or the US session opens.
