Getting Started
xDFi is the base layer that connects fragmented DeFi liquidity into one synchronized network — allowing every chain, regardless of size, to access the same depth of capital available on Ethereum.
What is xDFi?
xDFi is an Omnichain Liquidity Synchronization Infrastructure.
It synchronizes liquidity and yield data across EVM chains in real time, so that tokens, vaults, and yields can exist as one unified balance sheet shared by all chains.
For smaller or emerging chains, xDFi effectively imports Ethereum’s liquidity and price depth — without bridges, wrapped assets, or custodial middle layers.
Users can deploy capital on a local chain and experience the same liquidity conditions as if they were on Ethereum, Arbitrum, or Optimism.
Why It Matters
DeFi liquidity today is fractured.
Each chain operates like an isolated jurisdiction with its own pools, prices, and incentives.
Bridges temporarily move tokens, but they don’t synchronize state — liquidity remains siloed.
xDFi solves this by introducing root-level synchronization:
Every chain publishes its LiquidityRoot and DataRoot each epoch.
These roots are verified and mirrored globally, allowing smart contracts to read the same liquidity snapshot everywhere.
This turns liquidity into a shared global constant, not a local variable of each chain.
Core Idea
Local Execution, Global Liquidity. Chains stay sovereign. Liquidity becomes universal.
xDFi isn’t a bridge, router, or sequencer.
It’s an infrastructure layer that unifies DeFi’s liquidity fabric — enabling every ecosystem to tap into the same capital depth, yield data, and risk visibility in real time.
Architecture Overview
Built on LayerZero’s trust-minimized messaging, xDFi adds deterministic liquidity synchronization and global data verification.
Each chain maintains:
LiquidityRoot — aggregated vault balances and pool depths.
DataRoot — yield metrics, risk parameters, and reward distributions.
Every few seconds (one epoch):
Chains publish LiquidityRoot + DataRoot.
xDFi Settlers verify deltas and broadcast the global synchronized root.
Smart contracts on all integrated chains validate proofs against that root.
Any transaction (swap, stake, borrow, yield claim) references this unified state before execution — ensuring that liquidity data, risk, and balances are globally consistent.
Key Benefits
1. Global Liquidity, Local Accessibility
Smaller or emerging chains can offer users the same liquidity and yield depth as Ethereum or major L2s — without bridges or custodians.
Liquidity and yield data are refreshed every epoch and verified on-chain.
Apps and users always operate on the most recent global state — no manual bridging or oracle delay.
3. Zero Added Trust
No new sequencers or validators introduced.
All state proofs are verified against on-chain roots, secured by LayerZero’s DVN and Relayer architecture.
4. Infrastructure for Liquidity Composability
Protocols can launch omnichain-native vaults or lending markets whose state automatically mirrors across chains — scaling TVL and user access without fragmenting liquidity.
Supported Use Cases
Chains
Integrate xDFi to give local users access to deep omnichain liquidity.
Your ecosystem instantly inherits Ethereum-level liquidity conditions and yield markets.
Protocols
Deploy vaults or lending markets that exist simultaneously across chains, under one synchronized state.
No more fragmented pools or manual bridge management.
Developers
Build DeFi products that rely on global liquidity or cross-chain yield data — without having to build custom bridging or synthetic token logic.
Users
Use local dApps and experience the liquidity, pricing, and yield depth of the global DeFi market — seamlessly and transparently.
Executive Summary
xDFi transforms isolated DeFi ecosystems into a synchronized liquidity network.
It’s not about moving assets between chains —
it’s about letting every chain act as a gateway to global liquidity.
