machineTokenFundingUrl

Builds a Tempo Wallet link to buy MACH, optionally prefilled with a payer and amount.

Usage

import { machineTokenFundingUrl } from 'mppx/tempo'
 
// The onramp sells MACH only on mainnet; Moderato has no funding link.
const url = machineTokenFundingUrl({ chainId: 42431 }) 
console.log(url)
undefined

The onramp supports Tempo mainnet only. Omitting chainId uses that network. Tempo.machineTokenFundingUrl from mppx exposes the same helper.

machineTokenFundingBaseUrl, also exported from mppx/tempo and Tempo, is https://wallet.tempo.xyz/agent?action=fund&intent=mach&chainId=4217.

Return type

type ReturnType = string | undefined

Returns undefined for any chain other than Tempo mainnet. Invalid addresses and non-positive amounts are omitted from the URL. Valid addresses are checksummed; amounts round up to whole cents and omit trailing zeroes. For example, 1_250_001n produces an amount=1.26 query parameter.
