HALLIDAY

Halliday is a blockchain company and product lab working to create a unified, cross-chain payments ecosystem. Its flagship offering, Halliday Payments, is a unified payments platform that enables users to onramp from fiat, swap across chains, and take onchain actions with minimal friction. The platform integrates top bridges and DEXes, instantly adding new pathways to tokens while intelligently routing through the best onramps based on geography, payment method, and latency. Backed by a16z crypto and Hashed, Halliday has worked with prominent developers including ApeChain, Story Protocol, and DeFi Kingdoms to provide seamless experiences for both developers and end users. 

The company operates on a fully non-custodial basis, meaning users connect their own wallets (such as MetaMask) and retain complete control of their funds at all times. Halliday never takes custody of user assets. Developers can integrate the payment solution with just 7 lines of code using the SDK widget, or leverage the headless API for complete customization. The platform supports any token on any chain, making it a universal payment infrastructure layer for the multi-chain web3 ecosystem. Halliday raised $20 million in Series A funding in March 2025, bringing total raised to $26 million.
