Notes

This tool does maths only. It never connects a wallet, moves funds, or stores anything.
Rates are fetched once from a public exchange API when you load them, and are indicative — the real rate on any exchange or on Bridge Swap will differ and includes a fee.
Cryptocurrency prices are volatile; a converted figure can change within seconds.
Stablecoins (USDT, USDC) are treated as exactly $1 for the conversion.
