如何找到 Golem Network Token (GNT) TokenTrader 合約列表？
Golem 網路代幣 (GNT)
TokenTrader合約實現了 GNT 的去信任和去中心化銷售乙太幣 (ETH)。賣方
TokenTrader使用TokenTraderFactory.createTradeContract(...)方法，指定他們想要出售 GNT 的價格，然後用 GNT 充值契約。原作者的說明可以在這裡找到。買方只需將 ETH 發送到賣方部署的
TokenTrader合約，並將 GNT 接收回買方地址。更多資訊可以在https://www.bokconsulting.com.au/blog/trustless-token- sell -contract/和https://www.reddit.com/r/ethtrader/comments/5cnl58/trustless_gnt_ sell_contract/上找到。

- 此腳本列出了所有已部署的 TokenTrader，即使是那些部署有一些錯誤的。錯誤部署的 TokenTrade 的 Sell price 和 Units 欄位通常是非常不正確的。
- 如果您確實想嘗試從這些合約中購買 GNT，請先進行少量測試。
- 這只是查找契約的工具。您對契約的使用是您自己的責任！
