Los contratos Golem Network Token (GNT) TokenTraderpermiten la venta descentralizada y sin confianza de GNT por éteres (ETH).

Un vendedor implementa uno de estos TokenTradercontratos utilizando el TokenTraderFactory. createTradeContract(...)método, especificando la tasa a la que quieren vender sus GNT, luego recargar el contrato con GNT. Las instrucciones del autor original se pueden encontrar aquí .

Un comprador simplemente envía ETH al TokenTradercontrato implementado del vendedor y recibirá los GNT en la dirección del comprador.

La lista de contratos actualizada en vivo ahora está disponible en https://cryptoderivatives.market/ .

Puede encontrar el siguiente script en https://github.com/bokkypoobah/FindGNTTokenTrader/blob/master/findGNTTokenTrader .

# Find Golem Network Token (GNT) Token Trader information
# 
# Works on Linux and OS/X. May work on Windows with Cygwin.
#
# Usage:
#   1. Download this script to findGNTTokenTrader
#   2. `chmod 700 findGNTTokenTrader`
#   3. Run `geth console` in a window.
#   4. Then run this script `./findGNTTokenTrader` in a separate window.

#
# Notes:
#   * This scripts list all deployed TokenTrader, even those deployed with some
#     errors. The Sell price and Units fields for the TokenTrade deployed
#     with errors is normally crazily incorrect
#   * If you do want to try purchasing GNTs from these contracts, test with
#     a small amount first

Estos scripts enumeran todos los TokenTrader implementados, incluso aquellos implementados con algunos errores. Los campos Precio de venta y Unidades para el TokenTrade implementado con errores normalmente son increíblemente incorrectos.
Si desea intentar comprar GNT de estos contratos, pruebe primero con una pequeña cantidad.
Esta es solo una herramienta para encontrar los contratos. ¡Su uso de los contratos es su propia responsabilidad!
