What Zyfi does

Zyfi is a paymaster-as-a-service platform built natively on the zkSync layer-2 ecosystem, enabling dApps to sponsor gas fees on behalf of their end users and allowing those users to pay transaction fees in any ERC-20 token. Launched in June 2024 by Ondefy Labs and headquartered in Switzerland, the platform is structured around an Intent-Based API architecture that operates as a Solver within the broader Intent landscape, supporting flexible per-transaction sponsorship models without requiring smart-contract changes by integrating dApps. Its product surface includes the core Zyfi Paymaster API, ZyfAI (an AI-driven DeFi yield optimization agent), a ZFI token bridge to Base, Passkey authentication, and a MetaMask Snap that renders paymaster transactions in human-readable form.

The platform serves primarily Web3 developers and protocols — including DeFi (PancakeSwap, SyncSwap, ZeroLend, KOI, RouterNitro), NFT (Hue NFT, ZkPengz), gaming (Mithraeum), and infrastructure (Magic.link) — operating across ZKsync Era, Cronos ZKevm, and Abstract testnets. Zyfi combines a product-led, API-first go-to-market (self-serve dashboard, SDKs, and a free tier with 2,000 monthly transactions) with ecosystem-driven distribution through its partnership with zkSync, including co-administration of a $100,000 Gas Grants Program. Revenue is generated via tiered API subscriptions (Standard $149-$449, Pro $299-$899), a freemium tier with 25% markup on sponsored transactions, and standalone ERC-20 Paymaster usage at 25% markup. The company reports 323,000+ users, 3.3 million+ transactions, and 41+ integrations, and is backed by a $2 million private funding round from crypto-native investors and individual angels tied to AAVE, Paraswap, Ledger, and Safe.

Zyfi operates with a small team (1-10 employees) under parent company Ondefy Labs, and its core platform has been audited by Cantina. The company's strategic posture emphasizes ecosystem lock-in within the ZKsync ecosystem, horizontal expansion across use cases, and incremental product extensions (AI agent, bridge, MetaMask Snap) layered on top of its core paymaster infrastructure.

Direct peers

• Pimlico: Pimlico is a leading Account Abstraction infrastructure provider offering bundler and paymaster services for ERC-4337 smart accounts across EVM chains. It competes head-to-head with Zyfi in paymaster-as-a-service for dApps, with similar API-first developer positioning.
• Biconomy: Biconomy provides gasless transactions and multi-chain relayer infrastructure for dApps via APIs and SDKs, overlapping directly with Zyfi's paymaster and token-agnostic fee payments offering for EVM-compatible chains.
• Stackup: Stackup offers paymaster and bundler services for smart accounts on Ethereum and L2s, competing in the same gas-sponsorship and developer-API category that Zyfi serves for zkSync and other chains.
• ZeroDev: ZeroDev provides smart account infrastructure including paymasters, session keys, and account abstraction SDKs. It is a comparable developer-facing AA platform to Zyfi, with overlapping customer profiles of dApp and wallet builders.
• Etherspot: Etherspot delivers Account Abstraction and paymaster infrastructure with a focus on multi-chain smart accounts, directly competing with Zyfi's paymaster API and multi-chain (ZKsync/Cronos/Abstract) coverage.

Broad incumbents

• Safe (formerly Gnosis Safe): Safe is the dominant smart contract wallet and AA infrastructure provider across EVM, with broader wallet and multi-sig scope. Zyfi's Passkey feature and Magic.link integration compete in adjacent AA UX, and Safe's scale represents both a partnership vector and a competitive ceiling.
• Thirdweb: Thirdweb is a broad web3 development platform offering smart accounts, gasless transactions, and developer tooling. It overlaps with Zyfi's paymaster and gasless transaction API at the developer platform layer with much wider feature scope.
• Alchemy: Alchemy is a major web3 infrastructure provider whose Account Abstraction and gas manager products compete with Zyfi's paymaster. Alchemy serves a much broader developer base across multiple chains, representing a large-competitor threat.

Emerging players

• Particle Network: Particle Network provides chain-abstracted smart account infrastructure including gas abstraction and AA wallets. It overlaps with Zyfi's intent-based, token-agnostic gas payment and AA positioning, with a comparable focus on multi-chain UX.
• Rhinestone: Rhinestone offers modular smart account infrastructure focused on 4337 interoperability, overlapping with Zyfi's AA and paymaster stack from an emerging-player angle with similar developer API positioning.
