Who publishes this content
This site's Chinese guides are published by FeilongEX, organized with AI assistance, and checked against the listed sources. The article byline represents the publishing organization and does not mean that a licensed expert with an undisclosed name reviewed it. We do not fabricate author credentials, independent reviews, customer testimonials or transaction success rates.
FeilongEX provides and is responsible for the exchange service, Chinese interface, and help content; external technical materials are used only to explain the corresponding fields and general network rules. See About FeilongEX for platform information, and see Terms of service for the conditions of use for this order. The guide does not provide investment return judgments.
Different explanations use different bases
Network and asset: gives priority to blockchain protocols, token issuers, and official network documentation. Asset names, token contracts, and user receiving addresses are verified separately; community paraphrases are not used to replace these key bases.
Quote and order field sources: quote fields, confirmation flow, regional conditions, and refund rules refer to the corresponding official materials; FeilongEX's customer commitments are subject to the site's current terms of service.
FeilongEX's own features: interface operations, order lookup, and fee refund explanations are checked against the current functions and the rules published on this site. See Fee refund rules for the campaign calculation basis. Sources near the main text support the corresponding explanations, and the complete materials are listed at the end.
Official sources, quote observations and real transactions are labeled separately
Official documentation explains fields or rules; interface observations record what was returned at a certain time with a certain set of inputs. Neither alone can prove that real funds have completed an exchange.
On 2026-9-10, we collected 9 read-only quotes through the local FeilongEX server-side quote interface. The sample covered multiple exchange directions and included two floating queries with the same parameters and one fixed-mode query. All records came from the same day, with the first and last observations about 17 minutes 46 seconds apart, so they can only serve as a single-day snapshot and cannot represent a seven-day trend, long-term average fees, the lowest price or transaction success rate.
This time only quote queries were performed; no orders were created, no funds were sent and no real exchange payment was verified. Historical records are used to explain quotes, cannot be used directly for payment, and are not continuously valid prices. The public data does not include quote tokens, order numbers, Cookies, user addresses or access credentials.
可查看 Observation records for TRON → Ethereum、Records for the opposite direction与 BTC route records。若将来引用真实资金测试，将另行写明实际执行范围与可核验结果。
同日第二批查询补充了 USDT TRON → BTC、ETH → USDT Ethereum和 USDT Ethereum → ETH。另以 100 USDT Ethereum → BTC 做了两次浮动查询和一次固定查询：Records with the same parameters说明比较的边界，Mode comparison分开列出报价有效期与尚未取得的订单付款期限。这些样本不能支持长期平均费用、最低价或成交成功率结论。
See Quote observation guide for the complete methodology, nine records, and explainable scope. A machine-readable version can be downloaded from Public JSON data; when citing, the observation time, number of inputs, assets, networks, and rate mode should also be retained.
How calculation examples avoid being misleading
Manually set numbers are marked as hypothetical examples before the table; real query records are marked with time and inputs. When fees are measured in different currencies, first list the units and conversion basis; ETH, TRX and USDT cannot be added directly. Costs already included in the quote are also not deducted again.
Fee comparison example explains the difference between total outlay and estimated receipt. The subsidy calculated in the campaign based on the saved quote does not masquerade as the final actual fee bill; "submit refund address" is also not written as "paid." Completed exchanges, order refunds, and fee refunds are different records.
Currency availability, current prices, minimum and maximum amounts and payment deadlines are subject to the quote and order requirements returned by the page at the time of operation. The initial input on the page is only an editable starting amount, not an official minimum amount.
How to understand update and source review dates
"Published" records the first publication date; "Updated" records the date of substantive changes to that article's content; "Source review" records the date the official sources were checked. Newly added measured query records have their own times and do not mean that all cited documents were reviewed on the same day. Changing styles, republishing the site or refreshing quotes does not change all article dates on that basis.
Service rules may change after the source review. Dates are not a commitment to continuous monitoring or real-time review. The content revision on 2026-9-10 added route quote observations, network fee preparation, refund calculations and order troubleshooting, and corrected wording in older content that defined the boundaries of customer responsibility too broadly.
How to handle discrepancies in sources
If you find that an article is inconsistent with the current interface, interface fields or official rules, first record the article address, relevant paragraph, source link and viewing time, then recheck according to that matter. For questions involving payment amount, network, address or deadline, first confirm this order's requirements; old examples in articles cannot replace payment information.
After verification, substantive errors are corrected in the body text and update date; when the source remains unclear, the missing conditions should be clearly stated, and speculative numbers should not be added. We do not package quote responses, documentation descriptions or hypothetical calculations as completed real-fund tests.
