What is Halliday Payments?

Halliday Payments is a non-custodial, unified crypto payment flow that can be implemented by developers using only 7 lines of code. It orchestrates three different product categories – onramps, centralized exchanges, and bridges – into a single app, simplifying the experience for users and allowing them to get their first dollar onchain in less than a minute.

​
How does it work?

Halliday Payments is built on the Workflow Protocol, which is used to streamline blockchain development. Depending on the chain, traditional onramp providers may not be able to access liquidity, leaving users to figure out the best path on their own – a process that can take up to 30 minutes or more. Halliday Payments simplifies this process by offering seamless interoperability across different blockchain networks, ensuring users can easily deposit without having to navigate across different platforms. Halliday uses a broad network of integrations and support to create interoperability no matter the starting token or geographic location, creating a truly Web2-like experience.

​
What is a one-time wallet (OTW)?

Each unique payment begins with a new onchain address called a one-time wallet (OTW), also known as the deposit address or a single-program wallet (SPW). Each onramp or swap will create a new OTW that is controlled only by the owner wallet address specified in the API call parameters. In the event a payment gets stuck or is funded after expiration, the owner address has the ability to sign transactions to recover the assets from the OTW or retry the payment. End users control the OTW - Halliday never takes custody or control of user funds.

​
What can Halliday Payments be used for?

Halliday Payments is extremely flexible and can be utilized for a number of different business uses. This includes, but is not limited to:
  • Blockchains: Simple deposit to a specific token, expanding access to liquidity
  • Perps: Swap and stake automatically
  • Prediction markets: Deposit and immediately buy
  • Games: Easily purchase in-game assets
  • Launchpads: Onboard and swap between coins
  • Fintechs: On and offramp to stablecoins
The Workflow Protocol enables quick cross-chain development. Have an idea for a custom use case? Reach out to partnerships@halliday.xyz
