On-chain HEX token swap (Decentralized exchanges – DEX)

Warning: Network fees on Ethereum mainnet can be extremely expensive in times of network congestion. Layer 1 on-chain exchanges consume a lot gas.

Uniswap: Official Uniswap smart contract v1, v2 and v3 frontend. To access pairs with HEX select Token lists “1inch” or “Kleros T2CR”. Increase the Transaction deadline on Uniswap settings to prevent transaction timeouts.
The custom Uniswap v1 and v2 frontend ethhex.com has the HEX coin already selected.

1inch Exchange: DEX aggregator that allows limit orders. Searches for the best deal and executes trade. Beware of more expensive Ethereum fees.

Metric Exchange: DEX using the 0x protocol. Allows limit HEX/USDC orders on an order book.

Matcha: DEX aggregator that allows limit orders.

Bamboorelay: HEX/WETH pair only.

Paraswap: DEX aggregator.

Shapeshift DEX: DEX aggregator.

Metamask swap: HEX can be swapped within the Metamask wallet using the in-wallet swap function that functions as a DEX aggregator. It is the easiest way to buy HEX for new users, but the exchange fee of 0.875% is significantly higher than using a DEX directly (generally 0.3%) and consumes more gas (higher network fee).

Pine.finance: Smart contract that allows limit orders for Uniswap. New edition of the UniswapEX contract; not audited; support group @UniswapEX.

Mooniswap: Lately it has practically no liquidity, so check price slippage before executing the trade. Is more gas efficient than Uniswap or 1inch.

Renbridge: Bitcoin (BTC), Zcash (ZEC), Bitcoin Cash (BCH) and Dogecoin (DOGE) can be wrapped onto the Ethereum network trough RenBridge and the wrapped coins swapped to HEX using Uniswap or other DEX, or using the 1inch DEX aggregator.

Staker.app: Allows swapping USDC or ETH with HEX, staking and paying network fees with HEX, USDC or ETH. An excellent Android and iOS app for following your stakes, HEX statistics, and HEX related on-chain transactions. It also acts as a HEX contract frontend for Gnosis smart addresses generated by the app.

Direct fiat money on-ramps

Dharma: Direct fiat to crypto onramp/offramp linked to a bank account, but limited to USA accounts. Small fees, has a referral system, and allows up to 25,000 USD per week purchases, but holds assets for 7 days before they allow withdrawal.

Indacoin.com: Debit card purchase, not for USA citizens.

Transak.com: SEPA bank transfer or debit card (HEX is occasionally removed from the list of available coins).

Centralized exchanges (CEX)

List of centralized exchanges supporting HEX: HEX is listed on dozens of CEX. However, these require custody of funds and thus represent counterparty risks. If you have to use them, make sure you chose a trustworthy exchange with a good reputation.

Coinswitch: Aggregates liquidity from centralized exchanges; no KYC.

Changelly: Aggregates liquidity from centralized exchanges; no KYC.

ChangeNow: Aggregates liquidity from centralized exchanges; no KYC.

Atomic cryptocurrency wallet: Allows swapping HEX within the wallet and uses Changelly and ChangeNow.

A good option is also to buy ETH on a trusted and reputable CEX, such as Bitstamp, Kraken, or Coinbase, and then swap that ETH for HEX on Uniswap.

Layer 2 exchanges

HEX bridges to Polygon and xDai are currently available. Transactions on layer 2 cost nearly nothing and are very fast, but layer 1 fee still need to be paid for the bridge contract when transferring between layers. For this reason, layer 2 is currently mainly only useful for traders, or for cost averaging in or out.
Layer 2 solutions are not as secure and decentralized as mainnet, but they allow scalability.

Polygon network

Quickswap on Ethereum Polygon (Matic) layer 2 network has the largest HEX liquidity on layer 2 and decent volume (currently about 0.5M USD liquidity on each side and 100-200k USD daily volume). It is an AMM based DEX that is a 100% fork of Uniswap v2, thus audited and battle tested. Limit orders are available trough Sorbet finance contract.

Paraswap can be used on Polygon network. It is a DEX aggregator similar to 1inch.

Sushiswap on Polygon occasionally has tiny amounts of liquidity for HEX, but is currently not useful.

Transak.com allows direct fiat money onramp to Polygon network trough Matic by using SEPA bank transfer or debit card.

xDai network

Honeyswap on the Ethereum xDai layer 2 network has HEX listed, but there is little liquidity available at the moment.

 zkRollup

Loopring exchange using zkRollup layer 2 technology currently has a very small liquidity for HEX. Please check the price slippage before swapping.

Leverage and margin trading

Leverage trading is a zero sum game and extremely risky. The vast majority of leverage traders lose money, waste a lot of time in front of the screen, and destroy their health and relationships. Even the few that are good at it are generally being outperformed by hodlers holding assets with a good product-market fit. Do not leverage trade! If you cannot help yourself, limit yourself to minimal leverage, because cryptocurrencies are very volatile and your positions will get liquidated.
