LCX Liberty DEX is live, and the routing engine behind it is open to everyone
by LCX Team ·
Today we launched LCX Liberty DEX at dex.lcx.com. It is a non-custodial trading aggregator that works out its own prices by reading liquidity straight from the blockchains it trades on, moves value between any two supported chains in a single flow, and carries a multi-chain portfolio that opens on a wallet address alone. The same engine that prices the consumer product is available to any builder as an API, an SDK, an embeddable widget and a live MCP server.
This post explains what we built and why we made the choices we made. The short version is that we decided to own the hard part of the problem rather than rent it, and that decision shapes everything else in the product, including how we make money.
Where LCX Liberty DEX sits
LCX Liberty is the LCX DeFi product line: a family of non-custodial products built so that an asset can be owned, traded and tokenized without a custodian in between. Own it, trade it, tokenize it is the founding idea, and self-custody is the condition every product in the line holds an asset in, from the moment it is issued to the moment it is traded. LCX Liberty DEX is the first product in the line to go live in full. LCX Liberty Chain, which brings real-world assets on-chain, is on testnet, with LCX Liberty Explorer alongside it.
We started with trading on purpose. Tokenizing an asset is only worth doing if the asset can then be held, priced and traded without asking anyone’s permission, so trading is the piece that has to exist first for the rest to mean anything. LCX Liberty DEX is where self-custody stops being somewhere to keep assets and becomes somewhere to use them. It is also the layer the rest of the line will settle through, which means everything that follows inherits the routing, the pricing and the multi-chain reach that go live today.
Why we read the blockchains ourselves
Ask most aggregators for a price and they pass on an answer they got from somewhere else, from a pricing service they pay for and do not control. That middle step is invisible to the user and it is where a surprising amount goes wrong: stale quotes, missing venues, coverage that ends where the vendor’s coverage ends.
LCX Liberty DEX does not have that step. We watch the pools on every chain we support, keep our own live picture of where the liquidity is, and work the price out ourselves, on the spot, the moment we are asked. More than 400,000 pools and more than 400,000 tokens across 40+ venues, held in memory and priced there.
Three things follow from that.
It is fast. Nothing stands between the user and the number. There is no round trip to an outside service in the middle of a quote, because there is no outside service.
It is ours to answer for. When a route is wrong, we can find out why, and we can fix it. That is not a small thing. If the price comes from a vendor, the honest answer to a user’s question is that we do not know either.
It ranks routes by what actually arrives. The engine sorts by what reaches the user’s wallet after gas rather than by headline output, which are different numbers and sometimes very different numbers. Larger orders are split into pieces routed across different venues.
Why there is no platform fee
A platform fee on a swap never appears as a line item. It widens the quote, and the quote is the one number a user cannot check for themselves. Charging one means the user has no way of telling the difference between a good route and a worse route with a fee inside it, and the whole point of an aggregator is that the user should be able to trust the number.
So LCX Liberty DEX does not charge one. Users pay network gas and the fees charged by the pools their route uses, and nothing to LCX.
That is not generosity, it is where the business sits. The valuable thing we built is not a swap screen, it is the engine underneath it, and the engine is what we sell. Companies that want good execution without building the machinery to read every chain themselves can pay for the API. The trade is free because it is not the product.
Cross-chain, and what actually happens
Trading is multi-chain by design. Swaps run today on Ethereum, Base, Arbitrum One and OP Mainnet, and the architecture allows chains to be added without changing how the product works.
A cross-chain swap runs between any two supported chains, in either direction, quoted as one route and executed as one flow, with the cross-chain leg filled in seconds. The user picks what they are paying with and what they want to receive, and that is the whole interaction.
Underneath, three things happen: a swap on the source chain, a cross-chain leg, and a swap on the destination chain. The cross-chain leg runs over Across, where relayers fill the transfer and expected fill time is one to three seconds. We price all three together and run them as one action, so there is no separate bridging step, no wrapped intermediate token to understand, and no second application to visit.
We are describing the mechanism rather than waving at it because the alternative on most platforms is worse in a specific way: bridge, wait, then trade again on the far side, holding an asset through a gap the user did not ask for. Knowing what the gap is and how long it lasts is part of the product.
A portfolio that asks for nothing
Trading is one part of what LCX Liberty DEX does. Alongside it sits a full multi-chain portfolio that opens on a wallet address alone: no account, no email, no signature, and no permission granted to anything.
It reads token holdings and how they are allocated, DeFi positions including concentrated liquidity down to the fees each position has accrued, NFTs, perpetual positions, and the wallet’s transaction history, across every supported chain in one view. A token and pool explorer sits alongside it, priced from the same live view of the market that the router trades on, so the number a user sees while researching is the number the router would trade on.
There is nothing clever about this and that is the point. It is a read of public chain state, which is all a portfolio ever needed to be.
LCX Liberty Labs Inc. never holds user funds. Your keys. Your assets. Your control.
The engine is the business, and it is open
Everything above is available to builders. Wallets, exchanges, trading interfaces, treasury tools, payment flows and autonomous agents can integrate the routes and skip the infrastructure entirely.
It ships as a public REST API, a TypeScript SDK, and an embeddable swap widget that drops into an existing product. One integration covers every supported chain, cross-chain routing in either direction, and a live picture of 400,000+ pools, none of which the integrator has to build, run or keep current. The hard part is watching every pool on every chain and never falling behind, and it is already running.
The free tier covers 150,000 calls a month and requires no card. Paid plans settle in $LCX, USDC or USDT, with a 25 percent discount for settling in $LCX, the utility token connecting the LCX ecosystem.
The MCP server, and why it cannot spend
The MCP server is live. An AI assistant can connect to LCX Liberty DEX directly and price a trade, resolve a ticker, read a token price or list the supported chains, reading the same live market data and the same router the application uses.
Every tool it exposes is read-only by construction. An agent can find the best route and explain it, and it has no ability to sign, spend or move anything. There is no permission to misconfigure and no key to leak, because the capability was never built.
We think this is the right default and we want to be plain about why. As assistants start doing real work on behalf of people, the question stops being whether an agent can find a price and becomes what it is allowed to do with one. Drawing that line in the software is the only place it can be drawn honestly. A policy document is not a control.
“We have been building digital-asset infrastructure since 2018, and the lesson of those years is simple. Whoever sees the liquidity sets the price, and whoever sets the price holds the power. LCX Liberty DEX sees it for itself, on every chain we support, and we are opening that engine to everyone. Financial liberty for everyone is not something you can outsource.”

What this adds up to
LCX Liberty is that work opened up: non-custodial, built in the United States, with the pricing layer given away and the engine underneath it available to anyone who wants to build on it.
LCX Liberty DEX is live now at dex.lcx.com. Developers can start at the same address.
