Key changes
BNB supported as a wallet currency
We have introduced BNB as a supported wallet currency. Users can trade it via the new BNB/USDC spot pair and use it to offset their upside BNB risk in X:PM.
Solana added to cross-collateral pool
Solana (SOL) is now part of the cross-collateral pool. This enables users to trade BTC, ETH, USDC, and USDT-settled instruments using SOL as collateral.
API
Potential breaking change: Scientific notation in JSON responses
We have updated the JSON formatting of numeric values in our API responses. Starting with this release, some numerical values, such as prices, may be returned in scientific notation. For example:
-
Previously:"strike": 64000
-
Now:"strike": 6.4e4
Our system does not enforce a strict rule for its use, so numeric values may be represented either way.
Scientific notation is fully compatible with JSON standards and supported by most modern JSON libraries. Clients are advised to test their implementation against testnet to ensure compatibility.
Breaking changes
-
We have removed the legacy method
private/toggle_portfolio_margining. Clients are advised to use private/change_margin_model instead.
