## Quick answer
A listing announcement moves price in minutes and book depth over days, so day-one volume mostly reflects market makers and bots, as of October 2026. Our board ranks 24 venues, and FeeEdge's 17 August 2026 survey put entry-tier spot taker fees near 0.10%. Check depth at your size before you size.

## Summary
A listing announcement moves price first and depth second, and only the price move is fast. Announcement-day volume comes mostly from market makers seeding the book and bots closing the gap against other venues, and neither group is obliged to stay. Entry-tier spot taker fees sat near 0.10% in FeeEdge's 17 August 2026 survey, while L1 ERC-20 withdrawals cost $2 to $10 with congestion above $50. Walk the book at your size before you size, and price the exit before you enter.

## Key takeaways
- Announcement-day volume measures inventory that crossed, not liquidity that stayed
- FeeEdge's 17 August 2026 survey put entry-tier spot taker fees near 0.10%
- L1 ERC-20 withdrawals cost $2 to $10 on the same survey, above $50 in congestion
- The board ranks 24 venues on sampled 24h volume as of October 2026, with the top row near a third of the sample

## FAQ
Q: Why does volume spike on listing day if liquidity does not?
A: Volume counts turnover, and turnover can come from participants who have no intention of holding inventory. Market makers seed a new book under an obligation with a minimum size, and arbitrage bots trade the new pair against the same asset elsewhere. Both print volume on day one and both can be gone by day three.
Q: How long does a new pair take to trade like a mature one?
A: In practice the spread compresses over days rather than hours, as a second and third maker arrive and as the venue's fee tier attracts flow that makers can warehouse. There is no fixed schedule, and some pairs never reach the depth of the venue's established books.
Q: What is the cheapest check before buying a newly listed pair?
A: Walk the ladder at the notional you actually intend to trade and compare the average fill with the touch price. That single number captures spread and slippage together, and it costs nothing but a few seconds before the order.
