FundingSource.dex

Creates a native DEX funding source that exchanges an input token for the required output token. The helper supplies the native DEX funding source address and encodes its arguments.

Usage

import { parseUnits } from 'viem'
import { Addresses, FundingSource } from 'viem/tempo'
 
const source = FundingSource.dex({
  maxAmountIn: parseUnits('30', 6),
  tokenIn: Addresses.alphaUsd,
})

Parameters

tokenIn

• Type: Address

Input token to exchange. The funding requirement specifies the output token and required balance.

import { Addresses, FundingSource } from 'viem/tempo'
 
FundingSource.dex({
  tokenIn: Addresses.alphaUsd, 
})

maxAmountIn (optional)

• Type: bigint
• Default: 2n ** 256n - 1n

Maximum input consumed per source invocation, in input-token base units. Zero permits no input. Omission leaves this cap unlimited; policy and slippage limits still apply.

import { parseUnits } from 'viem'
import { Addresses, FundingSource } from 'viem/tempo'
 
FundingSource.dex({
  maxAmountIn: parseUnits('30', 6), 
  tokenIn: Addresses.alphaUsd,
})

Return Type

FundingSource.Source, containing the native DEX source address as target and ABI-encoded arguments as data.
