Our verdict on Poloniex

6.8/10

Poloniex suits traders who want a conventional order-book exchange with spot, margin and derivatives markets plus a mobile app. Its main strength is the range of trading products and on-chain wallet balances of about 1.0 billion USD across many networks. The main caveat is custody: funds sit with the operator, no audits are listed, and fees, licensing and KYC rules are not public. Verify these on the official site first.

What is Poloniex?

Poloniex is a centralized cryptocurrency exchange where users deposit, trade and withdraw digital assets. DefiLlama describes it as offering order books, spot trading, derivatives markets and custodial wallets operated by the platform. The homepage promotes trading BTC, ETH, TRX, USDT and other altcoins.

DefiLlama tracks about 1.0 billion USD in wallet balances across Ethereum, Tron, XRP Ledger, Polygon, Stellar, Solana, Ethereum Classic, Arbitrum, Optimism, Bitcoin and Cardano. The seven-day change was about -0.3 percent. The exchange has no native token listed in the data.

Public reporting shows an iOS app, a login page in several languages and a promotion for cross margin trading with 3x leverage. Details such as licensing, fees and supported regions are not.

How Poloniex works

Poloniex is a centralized exchange. Users deposit crypto into wallets controlled by the platform, and the exchange records balances in its internal database. Trades happen on an order book, where buy and sell orders are matched by the exchange rather than by smart contracts.

Because trades are matched off-chain, they are fast and cheap, but users rely on the operator to hold funds honestly and process withdrawals. On-chain activity occurs only when users deposit or withdraw.

DefiLlama counts the assets held in the exchange's known wallets as TVL, about 1.0 billion USD at the time of the data. This measures reserves visible on-chain and is not a measure of audited solvency.

Watch out for

Custodial model: users do not control private keys while funds sit on the exchange.
DefiLlama lists no audits, and no proof-of-reserves details appear.
Fee schedule, KYC rules and licensing are not stated.
Leverage and derivatives products carry high risk of loss and are not suited to beginners.
Supported countries and regional restrictions are not published publicly, so availability must be checked.
No native token is listed in the data, so there is no token-based fee discount to evaluate.

Poloniex fees

Poloniex's fee schedule is not included, so no maker, taker or withdrawal rates are stated here. Centralized exchanges typically charge trading fees per order, plus network fees on withdrawals.

Users should check the fee page on the exchange and any margin or derivatives cost terms before trading. The cross margin promotion in public reporting mentions a zero interest rate in auto-borrow mode, but terms may change.

Is Poloniex safe?

Poloniex is custodial, so users depend on the operator to secure funds and process withdrawals. DefiLlama lists no audits for it, and the project does not describe proof of reserves, insurance or past incidents. Treat any exchange balance as an unsecured claim on the operator and keep only what you need for trading.

Licensing and regulatory status are not stated publicly. Rules differ by country, so check whether the exchange is permitted where you live. Leveraged products can cause rapid losses, so only trade with money you can afford to lose.
