A place for developers to talk about building on Farcaster.

Has anyone built a dead simple uniswap ts library for getting quotes with viem?

Working on @beliefs - most customizable launchpad on Base.
Coding FC related stuff.
Occasionally trading.
Figuring out how to fix my sleep schedule.

Here’s the plan 

We tag @dalechyn.eth 

Then we wait

if y'all checked /devfc TG you'd see

```

import Decimal from 'decimal.js'

import { uniswapV3PoolAbi } from '@/lib/abis/uniswapV3Pool'

import { publicBaseClient } from '../publicBaseClient'

export type GetEthPriceReturnType = number
export type GetEthPriceErrorType = Error

export async function getEthPrice(): Promise<GetEthPriceReturnType> {
  const [sqrtPriceX96] = await publicBaseClient.readContract({
    abi: uniswapV3PoolAbi,
    functionName: 'slot0',
    address: '0xd0b53d9277642d899df5c87a3966a349a798f224'
  })

  return new Decimal(sqrtPriceX96.toString())
    .pow(2)
    .div(new Decimal(2).pow(192))
    .mul(new Decimal(10).pow(12))
    .toNumber()
}
```
