amm.mint

Mints liquidity tokens by providing a token pair. Learn more about the Fee AMM

Usage

example.ts
import { Actions } from 'tempo.ts/wagmi'
import { parseUnits } from 'viem'
import { config } from './wagmi.config'
 
const { liquidity, receipt } = await Actions.amm.mintSync(config, {
  to: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
  userTokenAddress: '0x20c0000000000000000000000000000000000000',
  validatorTokenAddress: '0x20c0000000000000000000000000000000000001',
  validatorTokenAmount: parseUnits('100', 6),
})
 
console.log('Liquidity minted:', liquidity)

Liquidity minted: 100000000n

Asynchronous Usage

The example above uses a *Sync variant of the action, that will wait for the transaction to be included before returning.

If you are optimizing for performance, you should use the non-sync amm.mint action and wait for inclusion manually:

import { Actions } from 'tempo.ts/wagmi'
import { Actions as viem_Actions } from 'tempo.ts/viem'
import { waitForTransactionReceipt } from 'wagmi/actions'
import { parseUnits } from 'viem'
import { config } from './wagmi.config'
 
const hash = await Actions.amm.mint(config, {
  to: '0x742d35Cc6634C0532925a3b844Bc9e7595f0bEbb',
  userTokenAddress: '0x20c0000000000000000000000000000000000000',
  validatorTokenAddress: '0x20c0000000000000000000000000000000000001',
  validatorTokenAmount: parseUnits('100', 6),
})
const receipt = await waitForTransactionReceipt(config, { hash })
 
const { args: { liquidity } } 
  = viem_Actions.amm.mint.extractEvent(receipt.logs)
