Preparing liquidity for a CEX listing: a checklist

A centralized exchange listing is a one day revenue moment wrapped inside a longer relationship. Most of the outcome is decided before the market opens, in preparation a founder can actually control. This is the checklist we would run with a token team ahead of a listing, and what to watch once it goes live.

It assumes you are working with a market maker, or deciding whether to. Nothing here requires trusting anyone's black box.

Before the listing

1. Capital for both sides of the book

A market maker quotes a bid and an ask. That means you need two kinds of capital, not one:

• Quote capital. Stablecoin or the quote asset, to fund the buy side of the book.
• Token inventory. Your own token, to fund the sell side.

If you arrive with only tokens and no quote capital, there is nothing to support bids on a dip, and the first sellers on listing day walk the price straight down. If you arrive with only quote capital and thin token inventory, the asks are shallow and the price spikes on any buying, then round trips hard. You want both sides funded, plus a reserve to reload after the first spikes get filled. Plan the split before the day, not during it.

Note what a market maker cannot do for you here. On a CEX it operates on trade only API access. It cannot move tokens between venues or top up your inventory itself. If inventory runs to one side, rebalancing is either a book side adjustment or a manual move your team makes. Budget the inventory up front so you are not scrambling live.

2. Understand the exchange's targets

The listing contract usually specifies operational targets: a maximum spread, a minimum depth within a price band, and a minimum daily volume figure. These are conditions of staying in good standing, not optional nice to haves. A token that drifts below them can be moved to a monitoring zone or delisted.

Get these numbers in writing from the exchange and make sure whoever runs your liquidity is designing to them. The daily volume figure in particular is a contractual threshold the venue imposes, and meeting it, sized to the contract and paced within venue tolerance, is a legitimate operational task. It is a compliance number, not a demand signal, and no one should sell it back to you as if it were real buying interest.

3. Set up trade only API keys

This is the security core of the whole arrangement. Your market maker never needs custody of your funds, and should never ask for it.

• Create API keys with permissions limited to read book, place orders, and cancel orders.
• Deny withdrawal, transfer, and account modification. A trade only key cannot move your money off the exchange, which caps the blast radius if the key is ever compromised.
• Keep the funds in your own exchange account. A market maker operates the book inside your account. It does not hold your assets.

If a prospective market maker asks for withdrawal permissions or custody, that is a hard stop. There is no legitimate market making reason for it at this tier.

4. Agree the targets in writing

Before anyone touches the book, put the mandate on paper:

• Target spread and the depth to hold within a defined price band.
• How inventory is split across bid, ask, and reserve.
• How the exchange's volume threshold will be met, stated plainly.
• Reporting cadence and what each report will contain.
• What happens around events you already know about, such as unlocks.

Written targets are what let you hold performance to account later. Vague verbal assurances such as "we'll keep it healthy" are not measurable and cannot be checked. Insist on numbers you can verify on the live book yourself.

5. Plan for cross venue price coherence

If you already trade somewhere, or you plan a second listing soon, price coherence across venues matters. When a token trades in two places, the prices should stay close after fees, or one venue prints a misleading number and arbitrageurs feed on the gap.

Real listings stagger. One venue goes live, others follow later. Do not plan simultaneous launches across several exchanges. Sequence them, get the first venue's market healthy, and make sure your liquidity provider is set up to keep the second venue coherent with the first once it opens.

On listing day

The open is the revenue moment. Volatility spikes and trading runs two ways. The market maker's real job in the first hour is to work both sides of the book: taking profit into upward spikes, reloading bids on dips, refilling asks after fills, and watching that inventory does not skew too far one way.

What you should watch, and what you should not expect:

• Watch depth and spread on the live book. You can see them yourself. Are bids reloading after they get hit? Is the spread holding near target?
• Do not expect a live trade by trade feed. A market maker's book operates quietly. Your operator summarizes when there is something worth summarizing, rather than pushing every fill in real time.
• Do not expect always on staffing. Small teams sleep and crypto runs around the clock. Agree in advance how incidents are handled, rather than assuming instant coverage at any hour.
• Do not read the volume tape as demand. Volume happens naturally during a volatile open. The number rising is not evidence of organic buying, and no one should present it to you that way.
• Ask specific questions. "Is depth holding on the bid side?" is answerable. "How's it going?" invites reassurance rather than information.

For the first twenty four hours the work stays heavy, then eases toward a standing daily rhythm as volatility cools and the book settles. The first written report typically lands at the end of the first week.

The short version

• Fund both sides of the book, plus a reserve.
• Get the exchange's spread, depth, and volume targets in writing.
• Use trade only API keys. Never grant custody or withdrawal.
• Agree the mandate, in numbers, up front.
• Sequence venues. Do not launch everywhere at once.
• On the day, measure the book yourself. Ignore the volume tape as a demand signal.

Before quoting anyone a mandate, we run a free market assessment: a look at your current book, the venue's requirements, and what liquidity your listing actually needs. If it is useful to have that picture before you decide anything, that is where we would start.
