We are excited to introduce Trademail to allow BSV users and businesses to send to any cryptocurrency account using Paymail.

Users of wallets including RelayX, SimplyCash, Dot, Moneybutton, Centbee and more can now send funds to any cryptocurrency address as simple as using your destination crypto address as the prefix followed by,, and respectively.

Today’s launch includes BTC, ETH, USDC, and USDT(ERC20) for any amount $5 and above.

For example you can open SimplyCash and send $5 to and USDC will arrive in your destination wallet within 5 minutes. Fees are currently ~3% depending on sent amount, and we will continuously work to lower it as volumes scale.

From the start, interoperable payments have been a cornerstone of Relay’s mission. We believe applications, businesses and merchants within Bitcoin SV and crypto generally will find interesting and powerful use cases for Trademail as a seamless way to hedge, convert, and send to the coin of your desire.
