On Feb 26th morning, Tokenlon team received a message from 0x @willwarren89 as follows: The well-known white-hat hacker @Samczsun found that Tokenlon 4.0 has a security vulnerability. This vulnerability has a high-risk level, which will not only affect the security of the transaction fee deposited on the platform, but also will affect the safety of user funds. In response, the Tokenlon team immediately launched defensive actions from these two dimensions.

1, Tokenlon team immediately withdrew a large amount of transaction fee tokens back to the treasury to ensure that there would be no loss of precipitation fees.

2, Tokenlon team…

A look at our recent developments

We released the Tokenlon 5.0 on December 23, 2020. As of 2021.03.12, USD 9.55 million have been accumulated in the Tokenlon fee contract. Substracting the cost of 2260 ETH (approximately USD 4.05 million) that Tokenlon pays for the user’s miner fee, net fee income is USD 5.5 million; that is for Tokenlon 5.0, which has been online for 80 days.

With Tokenlon 5.0, users get access to the liquidity of Uniswap, SushiSwap and Curve. …

Proposal 5: TIP5 — Reduce trading fees for LON pairs


Tokenlon protocol charges a standard trading fee of 0.3% for LON pairs. To take advantage of the recent public attention towards LON, the core team proposes to reduce the trading fees for LON pairs as part of our Spring Festival campaign. Reduced fees should help Tokenlon offer more competitive rates for LON pairs, therefore attracting more people to trade LON on Tokenlon.
