[ANN] Hodl Hodl p2p exchange public BETA launch

[ArturHodlHodl]

Hey Hodlers,

Today, Hodl Hodl, a P2P cryptocurrency exchange, has enabled contracts and trading functionality. From this moment on, until July 2018 - you can sign up and trade with zero commissions.

Join us at hodlhodl.com!

What is Hodl Hodl?

Hodl Hodl is a P2P cryptocurrency exchange that allows users to trade directly with each other and it doesn't hold user funds - locking it in multisig escrow instead.

How does Hodl Hodl work?

All trading activity happens directly between buyers and sellers, and without a middleman involved. Each time a contract is created between two parties, Hodl Hodl exchange generates a unique multisig escrow cryptocurrency address. The seller sends cryptocurrency from his wallet to this address, and when the cryptocurrency is safely locked in escrow, the buyer sends his fiat currency (such as EUR or USD) to the seller. Upon receipt of the fiat, the seller then releases the locked funds from escrow using his payment password, and the buyer receives crypto in his wallet.

Hodl Hodl key features

1. Secure: multisig (P2SH) contracts, you control the key to the funds in escrow;
2. Cheap: low fee – max 0.6% per trade (fees will only be implemented beginning July 2018);
3. Decentralized: P2P trades without KYC/AML;
4. Support of native Bech32 Segwit addresses;
5. P2SH-P2WSH Segwit multisig escrow addresses;
6. Truly global P2P cryptocurrency exchange;
7. Trade BTC and LTC;
8. We have a TESTNET version of our exchange - where you can trade with TESTNET BTC/LTC - without risking actual money.

Features we are offering with the first release of our exchange

Privacy-focused environment:

To trade on Hodl Hodl you don’t need to reveal your identity. Just sign up and you are ready to trade with complete anonymity and no restrictions.

Verification takes place on a voluntary basis - you may choose to get verified in order to receive some benefits, but it is not required.

Security:

Hodl Hodl does not hold any money (neither cryptocurrency, nor fiat currency), which increases security of your funds. Instead, we create a unique P2SH multisig escrow address on the Bitcoin or Litecoin blockchain for each trade.

P2P cryptocurrency exchange that supports Segwit:

We’ve been working hard to have Segwit enabled with our first release: we’re generating P2SH-P2WSH Segwit multisig escrow addresses for compatibility with non-segwit wallets for each contract, plus you can release or refund bitcoins from escrow to native Bech32 Segwit addresses. This means that you’ll spend less money on transaction fees.

Referral program:

As a bonus, we offer you a referral program where you’ll receive part of our exchange commission for every trade your referral participates in once we start charging an exchange fee.

You can earn up to 10% of our exchange commissions, depending on how many active traders you have referred to the exchange.

You may also reduce the exchange commission you’re paying to Hodl Hodl by referring at least one active trader. Once you’ve done this, you will receive a discounted exchange fee of 0.55% forever.

You can find more information on https://hodlhodl.com/users/referral_program and in our FAQs.

Progressive fee system:

Once we enable exchange fees there will be different exchange fee rates available:
 
1. An exchange fee of 0.6% is used for newly registered users.
2. An exchange fee of 0.55% is applied to referrals; users who’ve registered with Hodl Hodl using a referral code. As mentioned above, you can permanently lower your exchange fee to 0.55% by referring at least one active trader.
3. An exchange fee of 0.5% is applied to users who have passed the verification process.

Litecoin support:

Hodl Hodl also supports Litecoin with the same P2SH multisig escrow address functionality. We will apply no exchange commissions to Litecoin trades until July 2018.

Multi-language platform:

With this release, we’ll be supporting two languages: English and Russian. Our support team speaks both languages.

TESTNET version:

Before trading with real coins, we recommend you learn how to trade on Hodl Hodl exchange TESTNET. Link to TESTNET: testnet.hodlhodl.com.

The TESTNET version is identical to the MAINNET, except for one key difference: you are trading with TESTNET Bitcoins and Litecoins without risking any actual money.

Please, be aware that all trades happening on testnet.hodlhodl.com are with TESTNET Bitcoins/Litecoins. Never send any actual funds for Bitcoins/Litecoins received on testnet.hodlhodl.com.

We are opened in BETA-mode

For now, we are opened in BETA-mode until July 2018, which means a lot of new features are coming soon, but the main functionality of the exchange is ready and available now!

While we’re in BETA, we recommend you use following browsers to trade on our exchange: Chrome, Mozilla, Opera, Safari upgraded to the newest versions.

5. Adding new cryptocurrencies to the exchange;
6. Integration with wallet providers;

Looks very interesting.

Good luck with your project and I will be sure to look over the referral program. 

The crypto space needs more p2p exchanges.

[timerland]

Looks like a very professional project and extremely well thought out.

I think that the fact that Localbitcoins has recently made it a requirement for everyone that wants to advertise on their platform now makes it a lot easier for competitors such as you guys to enter the market. And to use multisig escrow, with support of other altcoins planned, I can see this going a long way to potentially overtake paxful if everything is done well.

It'll be hard to build a customer base that trusts you. These p2p exchanges require lots of trust, and people essentially use it as their wallet to store all their crypto. A new business can have a difficult time doing that. Also, gaining enough local users that actively advertise is gonna be hard, I searched and most of the offers are "anywhere" and aren't that appealing to someone using it locally.

Interesting P2P exchange project.
But I wonder if your project would be user-friendly and if the trading could be finished fast.

I just used the exchange, the seller received my bank transfer today he just wrote to me saying he can´t release the funds, he claims to be gotten the following message when attempting to release the BTC.

"Not enough funds on escrow address. Perhaps, the transaction to the escrow address hasn't been confirmed yet. Please try again later."

Just wworte to support and waiting to hear back from them, hopefuly it is something that can be fixed...

Thanks a lot! We'll start paying referral fees once Hodl Hodl implemented fees (Q3 2018).

How do you like the fact that we're not hoDling your funds? Also, have a question - why is it bad, that most of our users post global offers?

Interesting P2P exchange project.

Isn't it already user-friendly? Thanks for your review!

Just to clarify here - the problem really existed on our side, but we've fixed it in quick order and buyer successfully received his bitcoins.

Warning to everyone with account at HodlHodl p2p exchange, according to reports from users and from their own medium post, payment passwords for some users have been compromised!
This affected some contracts and they had to liquidate them to avoid loss of funds, and they are starting to migrate funds from old escrow they used.
It is interesting that one of the investors to HodlHodl is Bitfinex exchange, and this issue was first reported by @6102bitcoin on twitter.
They even posted a PGP signed message and signature to confirm ownership:

Dear all,

We wanted to make this blog post about recent events that happened at Hodl Hodl.

First of all, let us apologize for not setting up our communication in the proper way. To ensure that our communication channels are not compromised, we have published a PGP key on our website (see ToS section at lend.hodlhodl.com). Again, we could have handled the communication better, but we didn’t manage to ensure it with all the rush and actions we should be taking to protect our users.

Secondly, we have started migration/liquidation of user contracts to prevent the potential loss of funds. Unfortunately, our recent internal and external audit identified that some user payment passwords might have been compromised. This affected a limited number of contracts, but we are taking proactive measures to ensure that everyone is safe. We are still investigating these issues and building tools to easily migrate funds from old escrow to the new ones. We are going to publish a transparency report on the investigation of these issues and fixing them.

We have contacted external auditors and are doing external and internal audits on a daily basis.

If you have any questions — feel free to contact us through all our communication channels listed in our contacts section.

We continue working and doing our best to avoid any further issues. In the upcoming days, we will post several posts, including our security and transparency road map.
