Inside Terminal One Routing: How LI.FI Powers Best Execution
Every trade on Terminal One routes through LI.FI. Here is exactly how the routing engine works and why it matters for execution quality.
The Routing Problem
The on-chain capital markets span 7 major blockchain networks. Liquidity is fragmented across hundreds of DEXes, AMMs, and bridge providers. For any given trade, there are dozens of possible execution paths — and the difference between the best path and the worst path can be significant.
A trader swapping $10,000 from USDC to USDY might route through Ethereum directly (high gas, deep liquidity), bridge to Polygon first (lower gas, different liquidity), or take a multi-hop path through an intermediate asset. Without sophisticated routing logic, the trader is guessing.
Terminal One solves this with LI.FI integration — a routing engine that evaluates every possible execution path in real time and selects the optimal route automatically.
How LI.FI Works
LI.FI is not a bridge or a DEX. It is an aggregation and routing layer that sits above the liquidity ecosystem. When a Terminal One user initiates a trade, LI.FI:
Queries liquidity across all supported DEXes on all supported chains simultaneously. Calculates the expected output for each possible route, accounting for slippage, fees, and gas costs. Evaluates bridge options if a cross-chain path provides better execution. Selects the route that maximizes the net output for the trader. Bundles the transaction (or sequence of transactions) for execution.
From the user perspective, this all happens before the trade preview appears — typically in under 2 seconds.
The 7-Chain Advantage
Terminal One supports cross-chain routing across Ethereum, Arbitrum, Base, Optimism, Polygon, BNB Chain, and Avalanche. This means that liquidity anywhere across these 7 networks is accessible for any Terminal One trade.
A wallet on Arbitrum buying a tokenized T-bill that has its deepest liquidity on Ethereum does not need to manually bridge first. The routing engine identifies the cross-chain path, executes the bridge and swap in the optimal order, and delivers the target asset to the user wallet — in a single confirmed transaction where possible.
The Fee Structure
Terminal One charges 0.25% on executed swaps. This fee is among the lowest available for the level of routing sophistication and cross-chain access the platform provides. Importantly, 20% of this fee is redistributed monthly to active traders as USDC cashback — meaning the effective fee for active users is lower than the headline rate.
