What Halliday does
Halliday is a San Francisco-based blockchain infrastructure company founded in 2022 by Akshay Malhotra and Griffin Dunaif. The company has developed the Workflow Protocol — described as the first Agentic Workflow Protocol — a declarative computing layer for cross-chain and cross-block asynchronous execution that enables developers and autonomous systems (AI agents, software) to safely perform on-chain tasks with immutable guardrails enforced on-chain. The company pivoted from its original buy-now-pay-later-for-NFTs focus to a broader workflow and payments infrastructure positioning.
Halliday's commercial product surface is anchored by two core offerings. Halliday Payments is a unified crypto payments suite that consolidates fiat onramps (Stripe, MoonPay, Transak, Coinbase Pay), bridges (Stargate), DEXs, and centralized exchanges into a single API or 7-line-of-code widget, supporting onramp, cross-chain swap, bridge, and deposit flows. Smart Accounts (ERC-4337) provide non-custodial, programmable wallets with social login, session keys, and gas sponsorship, purpose-built for Web3 gaming. Sub-products include HalliPay, Session Keys, Direct NFT Checkout, and a Growth Suite with NFT trials and subscriptions. The Claude Code Plugin extends the developer experience into AI-assisted natural-language integration.
Halliday serves Web3 gaming studios (DeFi Kingdoms, Shrapnel, Tiltyard, MetaDOS, Aether Games, ApeChain), appchains and L1/L2 networks (Story Protocol, SKALE, Caldera, Ava Labs), DeFi protocols, and is positioning into fintech and banking channels via the Mastercard Crypto Partner Program. The business model is transaction-fee based with no public pricing — revenue is generated as a take rate on payment and processing volume plus a cut of solver network fees. GTM is API-first self-serve for developers, complemented by direct enterprise sales for flagship integrations and channel partnerships with infrastructure providers (Caldera, Pimlico, Web3Auth). The company has raised $26M total from a16z crypto (lead in both rounds), SV Angel, Credibly Neutral, Avalanche Blizzard Fund, and angels from Coinbase, Story Protocol, Celestia, and Alchemy.

Halliday competitors and assessment
Company assessmentDirect peers
- LI.FI: LI.FI is a cross-chain bridge and DEX aggregation API that lets any Web3 app offer users the best swap and bridge routes. Directly comparable to Halliday Payments: same target customer (Web3 developers), same delivery model (API/SDK + widget), and overlapping protocol coverage.
- Squid Router: Squid provides cross-chain swap and bridging for any token via a single API, with one-click UX for end users. Closely mirrors Halliday's onramp/bridge/cross-chain swap/deposit value proposition for Web3 app developers.
- Rango Exchange: Rango is a multi-chain DEX and bridge aggregator exposing its routing logic as APIs for wallets and dApps. Directly comparable to Halliday Payments as a backend orchestration layer for cross-chain commerce flows.
- Socket: Socket (now part of the Modulr family) provides chain-abstraction infrastructure and Bungee cross-chain swap APIs for dApps. Competes head-to-head with Halliday's intent-based cross-chain orchestration for Web3 applications.
- deBridge: deBridge is a cross-chain interoperability protocol offering messaging and liquidity transfer between chains. Overlaps with Halliday's Workflow Protocol on cross-chain execution and orchestration for appchains and L2s.
- Across Protocol: Across is an intent-based cross-chain bridge optimized for fast, cheap transfers between EVM chains. Competes with Halliday's bridging/cross-chain swap capabilities and shares the same intent-driven design philosophy.
Broad incumbents
- LayerZero: LayerZero is the leading omnichain messaging protocol underpinning many cross-chain apps. Functions as a broad incumbent infrastructure layer that competes with Halliday's orchestration stack at the messaging/verification layer.
- Wormhole: Wormhole is a cross-chain messaging protocol connecting multiple blockchains, with broad adoption across DeFi and gaming. A broad incumbent in the same cross-chain infrastructure space Halliday orchestrates on top of.
Emerging players
- Particle Network: Particle Network offers chain abstraction and account abstraction primitives including smart wallets and universal accounts. Adjacent competitor to Halliday Smart Accounts and chain-abstracted onboarding for Web3 apps.
- Magic Eden: Magic Eden is a leading NFT marketplace that has expanded into gaming and chain-abstracted payments. Overlaps with Halliday's NFT checkout, gaming monetization, and Web3 payments positioning.
