As part of ongoing efforts to streamline and maintain our API, we are deprecating several Insight Service endpoints that have seen limited usage.

You can now specify custom slippage tolerance on the /bridge/swap endpoint. With the slippageToleranceBps parameter, you can specify how many basis points in slippage your swap can tolerate. Warning: Lower slippage tolerance values could result in reverted swaps. Without this value specified, it will continue to use the default

This dramatically reduces friction: no extra signing steps, no manual execution flows. Just describe
