What this exchange is
WEEX has operated since 2018, is registered in Singapore and is known first for perpetual contracts: roughly a thousand of them, more than it has spot pairs with meaningful volume. Its own token is WXT.
It is not a top-five venue by turnover, and that defines its role in arbitrage: prices here diverge from the large exchanges more often, simply because the books are thinner and take longer to align.

Fees
Spot charges the same 0.1% to maker and taker, and the exchange publishes that rate in its own instrument directory, per pair. That is unusual: most venues make you hunt through a help section.
For arbitrage, note that volume discounts here are more modest than at the large exchanges. Two trades in a route cost 0.2%, and your break-even should be measured from that.
Withdrawals and networks
WEEX publishes its network list and fees openly, with no key and no authentication. USDT has more than a dozen networks here, and the gap between cheapest and dearest is over tenfold.
At the time of checking the dearest was TRON, and the cheapest were layer-two networks. This is the case where the habit of "withdraw over TRON, it is cheap" costs the most. Exact fees per network are in the table at the top of this page: they change, so check it rather than your memory.
P2P
The section lives at /buy-crypto rather than the expected /p2p, and is not easy to find first time. It carries around fifty currencies, with anywhere from a handful to a few dozen ads each.
The practical consequence: treat WEEX not as your main P2P venue but as a source of divergence. When ads are few, the price drifts from the market easily, and that is exactly where routes against other exchanges appear.

What is missing
A public listings feed: the exchange publishes announcements but offers no programmatic access to them, so WEEX does not appear in our listings timeline. Everything else — spot, futures, funding, transfers and P2P — is covered.
