Solid isn’t just another DeFi app. It’s a vertically integrated financial platform designed for real users. Built on the full Fuse stack, Solid combines self-custody, seamless performance, and real-time yield into one mobile-first experience. With gasless transactions, smart accounts, and no seed phrases, it removes the complexity that keeps most people out of crypto, making mainstream adoption finally possible.
At its core, Solid is more than just a DeFi app. It’s a vertically integrated ecosystem built on top of six years of infrastructure development from Fuse Network, an Ethereum Layer 2 platform designed for real-world payments and decentralized applications. From the chain and smart wallets to relayers, APIs, and a native DEX, every layer of Solid’s stack is optimized for speed, accessibility, and user control.
“We didn’t want to build a patchwork app,” said Mark Smargon, founder of Solid. “We wanted to build something that feels like modern fintech but is powered by decentralized infrastructure. Fuse gives us that full-stack control, without compromising security or performance.”
Full-Stack DeFi Meets Fintech Simplicity
Solid is powered by key components of the Fuse stack, including:
The Chain: A fast, Ethereum-compatible L2 with instant finality.
Smart Wallets: Powered by SAFE, enabling gasless, password-free experiences.
Middleware Infrastructure: Relayers, APIs, and subgraphs for seamless performance.
Yield Engines & Trading Layers: Featuring Algebra, Voltage, and Veda integrations.
Account Abstraction: Leveraging ERC-4337 for intuitive, self-custodial smart accounts.
With integrations like Turnkey for biometric login and Pimlico for seamless ERC-4337 execution, users onboard without seed phrases, avoid signing fatigue, and enjoy gasless transactions—no matter the device or asset.
Yield Designed for Real Life
Solid’s vaults are designed to actively manage assets through curated DeFi strategies across multiple chains and protocols, with the aim of optimizing for more stable returns. By leveraging Fuse’s wholesale gas pricing and real-time indexing infrastructure, Solid seeks to improve operational efficiency and reduce common cost and latency challenges.
Upcoming features will include:
The ability to spend yield with the Solid Card
Earning on tokenized representations of real-world assets, such as Tesla stock or gold
Access to lending and collateralization functionalities
Engaging in quests, earning points, and unlocking new application experiences
“Fuse gives us the infrastructure to go beyond crypto natives,” added Mark. “We’re building for everyone, people who want to grow their savings, spend easily, and access real financial tools in one tap.”
