NFTs are popular these days. But usual NFT designs are a bit like musical chairs and highly speculative: because 100% of your payment goes to the previous NFT owner, your NFT lacks intrinsic value. If you can’t find the next buyer, then the NFT becomes a bag.

KittenNFT solves this…


We introduced KittenSynthetic in our previous article:

Please read it for the basic designs of our BULL & BEAR leverage tokens.

KittenSynthetic is now online at https://www.kitten.finance/new/. Two markets are available at this moment (please feel free to contact us for adding more):

  • You can use USDC to 3x trade…


This is part 8 of the KittenSwap series, in which we gradually present our unified swap+lending+option product (https://kitten.finance).

Here we show our synthetic asset & leverage design using Chainlink feed.

We will begin with BULL and BEAR tokens, such as QQQ_BULL_3x and QQQ_BEAR_3x. The benefits of our design:

1. Suitable for long-term holding. No time decay.

It is…


Kitten.finance focuses on DeFi innovation. Shadow is our latest invention, which can work as a cross-chain bridge for any blockchains supporting smart contracts.

As its first application, here we show it is possible to deposit token on ETH, and claim farming rewards on Polygon (Matic), to significantly save gas for…


Here is Part 2 of our Low Degree Testing Series. Part 1 is at:

As an example, assume Bob’s claim is deg(f) < 256.

Bob constructs g(a,b,c,d), such that f(x) = g(x, x⁴, x¹⁶, x⁶⁴).

The task is to prove deg_a(g) < 4, deg_b(g) < 4, deg_c(g) < 4


You may have heard about zk-SNARK, zk-STARK, etc., which can be used for ETH Layer 2 scaling and more. An excellent explanation is Vitalik’s blog post:

The Low Degree Testing in zk-STARK can be confusing for most newcomers. It is usually explained using a recursive algorithm.

Here we provide…


This is part 7 of the KittenSwap series, in which we gradually present our next-generation swap+lending+option product.

The lending+option part will be our version of Aave+Hegic which works for all tokens, instead of a few high MC ones.

1. From Put-Call Parity to Lending

Consider the famous put-call parity:

In other words, ASSET = [CALL] +…


This is part 6 of the KittenSwap series, in which we gradually present our design for the next-generation swap+lending+option solution.

Consider lending. Currently we can only use a number of high MC tokens as collateral on major lending platforms, and low MC tokens are at a disadvantage.

This is part 5 of the KittenSwap series, in which we gradually present our design for the next-generation swap.

KittenSwap is at https://www.kittenswap.org/ and you can trade our first IKO (Initial KittenSwap Offering) token $LIQUID there.

In this article, we discuss a simple method to improve limit orders using AMM…


LIQUID (https://www.kittenswap.org/) has a ever-rising price floor, which means LIQUID holders will be able to lock LIQUID for risk-free ETH when our LIQUID lending contract is ready.

This lending contract will be available for all current LIQUID holders. There’s no need to do any migration.

1. Benefits for LIQUID: Less Selling, Easier Buying

For simplicity, assume the current…
