The LI.FI Product Stack: Seven Layers, One Integration

LI.FI is not a bridge aggregator. It is a full infrastructure stack. I was writing about Layer 5 when they shipped it live. Here is every layer and what just changed.

Just Shipped  ·  May 26, 2026

LI.FI launched LI.FI Intents two days ago — a modular full-stack execution engine built on the Open Intents Framework (OIF), led by the Ethereum Foundation. This post has been updated to reflect it.

When most people encounter LI.FI, they see a swap interface or a bridge aggregator. That is the top of the stack. What sits underneath is a seven-layer architecture, each layer doing a distinct job, and together making it possible to move, swap, stake, and deploy assets across any chain in a single step.

Understanding each layer is how you understand why LI.FI is structurally difficult to compete with. You cannot replicate one layer and call it done.

Layer 1: The Embeddable Widget

The Widget is the surface layer — a plug-and-play swap and bridge interface any application can embed. Works with React, Next.js, Vue, and Svelte. Fully customisable: layout, branding, wallet handling, and feature flags. Most users who interact with LI.FI-powered infrastructure are using the Widget without knowing it. The infrastructure is invisible. That is by design.

Layer 2: The Orchestration Layer

The Orchestration Layer is the brain. It knows where assets are across every supported chain, what they cost, and what yields are available. When a request comes in, it finds the optimal route and combines multiple steps into a single transaction where possible. This is what makes one-click cross-chain actions work at scale.

Layer 3: LI.FI Composer

Composer goes beyond bridging and swapping. It enables programmable multi-step flows: bridge into a yield vault, stake into a protocol, chain multiple cross-chain actions — all in one transaction. Bridge → swap → stake → deposit. One confirm. Cross-chain composability at the infrastructure level, not the application level.

The LI.FI Composer turns multi-step DeFi workflows into single transactions. The complexity lives at the infrastructure layer. The user sees one confirm.

Layer 4: The Aggregation Layer

The most comprehensive meta-level aggregation in the market. Connects to 29+ bridges and 33+ DEXs across 60+ networks. Users get the best price without knowing which protocol executes. Wrapped token variants, non-EVM differences, canonical token mapping — handled automatically in the background.

Layer 5: LI.FI Intents  LIVE MAY 26

This is the layer that just shipped. LI.FI Intents is a modular, full-stack execution engine that fulfills orders through a network of professional solvers competing to provide the best execution. It is built on the reference contracts of the Open Intents Framework (OIF) — a public-good initiative led by the Ethereum Foundation, with contributors including LI.FI, OpenZeppelin, Uniswap Labs, Hyperlane, and 30+ other teams.

The core problem it solves: intent stacks have historically been too rigid, forcing every application into a single shared execution model. Real-world assets are a clear example — RWA flows need permissioned solvers who can market-make those tokens directly. Generic solver sets cannot fill them. LI.FI Intents fixes this by making the stack modular and configurable at every layer.

LI.FI Intents is the OIF in production, at scale. Over $80B in volume, 100M+ transfers, and 1000+ integrations available to OIF-compatible solvers from day one.

What makes this significant beyond the technology: it is the orderflow. A solver who integrates the OIF integrates one of the largest orderflow sources in crypto immediately. The flywheel — orderflow attracts solvers, solver competition tightens prices, better prices attract more orderflow — now starts spinning at scale for an open standard.

Layers 6 and 7: LI.FI's Own Products

LI.FI Pioneer is LI.FI's own solver. It guarantees execution even when third-party solvers cannot fill, and helps institutions launch and distribute tokenised assets — RWAs and stablecoins — across LI.FI's network. With LI.FI Intents now live, Pioneer is one of the first production solvers operating on the OIF stack.

LI.FI Fly is a DEX aggregator built specifically for new and emerging chains. Day-one best-price swaps, instant access to competitive liquidity including private market makers.

Why the Architecture Matters

The layered design means each component is independently useful. Together they create a full infrastructure stack from UI to execution that no single protocol can replicate by adding one feature. And with LI.FI Intents now live on an open standard, the stack is no longer just LI.FI's to build on — it is the industry's.
