You might have heard the term “on-chain payments API” if you’re a business looking at Web3 commerce. But what does it mean, and how may it help your firm perform crypto transactions more easily?

BitLily is a means for freelancers, digital creators, and service-based businesses to accept crypto payments. You need to know how blockchain payments function to use decentralized payments well..


What Is an On-Chain Payments API?

A payments API on the blockchain connects businesses directly to blockchain networks like Bitcoin, Ethereum, and stablecoins like USDT and USDC. Every transaction is logged on-chain, which means it can be seen, tracked, and is safe. This is different from regular processors.

Businesses may accept cryptocurrencies with BitLily’s blockchain payment API without having to deal with middlemen or KYC problems. This makes it one of the greatest decentralized payment platforms for firms that are digital-first.


How BitLily’s On-Chain Payments API Works

  1. API Integration: Merchants connect BitLily’s Web3 payments API to their website or online store.
  2. Checkout for Customers: Customers choose a cryptocurrency, such as Bitcoin, Ethereum, or stablecoins.
  3. On-Chain Transaction: The blockchain gets the payment to confirm it.
  4. Settlement: Merchants can get paid in crypto or through BitLily’s crypto-to-fiat settlement API, which makes it easy to send money across borders.

This method does away with the need for banks or third-party processors, so businesses may accept payments straight instantly and from anywhere.
