FAQ

Emoon is a decentralized, peer-to-peer marketplace that uses the 0x protocol to enable trustless buying and selling of crypto assets on top of Ethereum.

If you want to sell an asset, you approve the 0x protocol to broker the transaction with a buyer of your asset. Your asset doesn't leave your possession until someone buys it.

If someone buys your item, Emoon injects your signed order into the 0x smart contracts, which transfers ownership of the asset to the buyer and sends funds from the sale to your account. This transfer of ownership is atomic and is handled by a smart contract on the blockchain.

At any time, you can cancel your listing and take your item off the market, no longer allowing Emoon to sell your asset.

As a buyer, you don't have to worry about a seller's reputation or the seller not delivering your item because the transaction is brokered by the blockchain. All you have to do is pay the Ether asked for by the seller.

Because of how the 0x protocol works, you will get paid in something called wrapped ether (WETH). WETH is identical to ether but it has to be unwrapped. One convenient place you can unwrap your ether is at the 0x portal. Learn more here.

We call into ETH Gas Station to determine the optimal gas price to set. By default, we go with the "safe low" which is explained here. To learn more about the concept of gas and Ethereum in general, see this post.
If you ever see unusually high gas prices, it means that your transaction will likely fail and you shouldn't submit the transaction.
