Server instructions

Tools for the Libre blockchain (BTC/USDT lending and DEX). Read tools are free. Compose tools return unsigned actions plus an ESR link; sign with your own key (WharfKit) and call push_transaction, or hand the esr link to a human wallet (Bitcoin Libre / Anchor). This server never holds keys.
