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

Warning: Network fees on Ethereum mainnet become extremely expensive due to the ongoing bull market cycle. Layer 1 on-chain exchanges consume a lot gas and are thus currently only reasonable for large amounts.

Uniswap: Official Uniswap smart contract v1 and v2 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 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.

Shapeshift DEX: DEX aggregator

Matcha: DEX aggregator that allows limit orders.

Bamboorelay: HEX/WETH pair only.

Paraswap: DEX aggregator

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) and Bitcoin Cash (BCH) 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

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

Transak.com: SEPA bank transfer or debit card.

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.

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 may be no useful liquidity available at the moment. May change in the future.

 zkRollup

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