Evaluation of the effectiveness of WET's public sale restarted anti-Bot mechanism
TL;DR
The anti-bot mechanism has proven highly effective . HumidiFi's WET public sale successfully restarted on December 8th at 16:00 UTC. The upgraded anti-bot system achieved a real user participation rate of approximately 95%, with 4,433 wallets successfully purchasing. Compared to the disastrous scenario of the first public sale being snapped up in seconds by a single entity with 1,000+ wallets, this restart has essentially achieved the goal of fair distribution.
Core Analysis
A Review of the First Public Sale Failure
The first public sale, held on December 4-5, 2024, was hit by a serious bot attack.
- Attack scale : A single entity controlled 1,000+ Sybil wallets (70% of the 1,530 participating wallets).
- Attack method : pre-signed transactions in bulk, each transaction packaged with an investment of 24,000 USDC to obtain approximately 350,000 WET.
- Result : The entire public sale quota was snapped up within 1-2 seconds, and real users ("weterans") were completely unable to participate in ChainCatcher bubblemaps .
- Response measures : HumidiFi immediately cancelled the public sale and the original WET tokens, refunded USDC to real participants, and deployed a new token contract , jupiterExchange.
| index | First public sale | Resumption of public sales |
|---|---|---|
| Percentage of real users | <30% | ~95% |
| Number of participating wallets | 1,530 | 4,433 |
| Robot control rate | 70% | ~5% |
| Sold out time | 1-2 seconds | Normal progress |
Upgraded anti-Bot mechanism
The Jupiter DTF platform and the HumidiFi team implemented a multi-layered protection system:
Technology upgrade :
- Smart Contract Rewriting : The Temporal team refactored the DTF contract, fundamentally preventing bulk transaction packaging for cryptoTimes.
- Security Audit : OSEC completes comprehensive audit to ensure contract security.
- Front-end verification : Requires access through the official front-end, blocking direct contract calls.
Participation restrictions :
- Wallet limit : Reduced from 1,000 USDC to 500 USDC per wallet.
- Blacklist mechanism : Excluding all identified bot addresses, those who attempt to snipe during the initial public sale will be "completely unable to obtain tokens."
- Priority Allocation : Wetlist and JUP stakers will receive a proportional airdrop of the new token jupiterExchange.
Actual effect data
Preliminary results after UTC went live on December 8th at 15:10 :
- Participation scale : 4,433 wallets successfully purchased, 60,000+ actual participants
- Percentage of genuine users : Based on wallet age analysis, approximately 95% are genuine users, with only 5% being suspicious.
- Robot control : No large-scale bundled transactions or Sybil cluster attacks detected.
- Technical performance : Startup was delayed by 40 minutes due to traffic and the deployment of the anti-bot system, but overall it was rated as a success and a fairer bubblemaps application.
Key improvement metrics :
- The actual user engagement rate increased from <30% to 95% (+217%).
- The number of participating wallets increased from 1,530 to 4,433 (+190%).
- The robot dominance rate dropped from 70% to 5% (-93%).
Community feedback and emotions
Positive aspects :
- Appreciation was given to the team for their quick response and transparent handling of the initial failure.
- The new measures have been recognized as effectively improving fairness.
- We have confidence in HumidiFi's technological capabilities (daily trading volume of over $1 billion, accounting for 35% of Solana's spot market) . x.com
Cautious attitude :
- There are doubts about the long-term durability of anti-bot measures.
- Concerns that a 40-minute delay and unexpected early activation may leave vulnerabilities
- Calls for the industry to introduce KYC or more robust algorithmic detection mechanisms (cryptoTimes)
Overall sentiment has shifted from strong negative sentiment following the initial public offering to cautious optimism, with acknowledgment of the effectiveness of the measures but vigilance regarding the risks associated with the Solana ecosystem's IDO robots.
in conclusion
HumidiFi's WET public sale relaunch validated the effectiveness of its multi-layered anti-bot mechanism . Through a combination of contract rewriting, strict restrictions, and address blacklisting, the real user participation rate reached 95%, a fundamental reversal from the disastrous initial public sale. Although system deployment caused a 40-minute delay, the overall execution successfully prevented Sybil attacks and bulk transactions, setting a new benchmark for fair launches of the Jupiter DTF platform and the Solana ecosystem. While the community still has reservations about the long-term sustainability of protection, the initial data from this relaunch demonstrates that the upgraded measures have been significantly effective at this stage.
