# @OxSimpleFarmer: Pair Tokens, auto-compounding ERC-20s on Uniswap v4 for Robinho

Source: https://x.com/OxSimpleFarmer/status/2110063423799345571

## Summary

Pair Tokens are a new type of ERC-20 that fuses two tokens into one auto-compounding asset backed by a full-range Uniswap v4 liquidity pool, according to developer @OxSimpleFarmer, who invented them using Uniswap v4 hooks. The author gives examples such as NVDASPCX, which combines the NVDA and SPCX stock tokens, and ETHNVDA, which combines ETH and NVDA. Anyone can call the compound function to reinvest the pair's LP fees back into the asset. Starting tonight, users can mint or redeem Pair Tokens for any pair on Robinhood Chain via the StonkBrokers website, with minting and redeeming free and a 10% fee on compounded LP fees used for $STONKBROKER buybacks.

## Article

This weekend I invented something new, a new type of token using Uniswap v4 hooks that I call a Pair Token.

A Pair Token is a new type of ERC-20. It is a fused, auto-compounding asset, a fusion of two tokens.

For example, the stock tokens NVDA and SPCX fused into a single tokenized version of the two, with the ticker NVDASPCX, or ETH with NVDA, creating ETHNVDA.

Each Pair Token represents a full-range Uniswap v4 liquidity pool.

So why mint these tokens?

These tokens are self-multiplying in terms of value, as at any moment anyone can call the compound function to compound the LP fees generated by the pair’s trading activity back into the asset.

The token represents a new financial primitive, as it represents a proportional value and moves as an LP position NFT would, except that it is auto-compounding and, thanks to its v4 hook, allows for compounding and self-growth.

Since it is an ERC-20, this token can be freely traded onchain, LPed, or even paired with a launchpad.

A new type of token for a new type of exposure and strategy.

Starting tonight, you’ll be able to mint or redeem Pair Tokens for any pair on Robinhood Chain via the StonkBrokers website.

Minting and redeeming are free, and the compounding process on the tokens incurs a 10% fee on the LP fees generated, which is used for $STONKBROKER buybacks.

I look forward to a new line of products and protocols on Robinhood Chain using this new financial primitive.
