ICO Market and Industry

In June 2017, the total funds raised by ICOs exceeded the amount that blockchain startups had raised from venture capital companies for the 12 months preceding it.  A lot of businesses are looking into ICOs, but without a doubt, it is easy to conclude that this phenomenal growth has left many gaps that have yet to be fulfilled. The existence of these gaps has resulted in a high barrier to entry for enterprises who have trouble trying to bridge their islands of existence to the rest of the crypto and mainstream economies. We are in a state of flux and solutions are needed to address these issues.


Comsa is a conduit for future ICOs that want to exist in the COMSA ecosystem. As part of the project, a COMSA team is now already in place to provide companies with consultation, expertise and solutions to support their very own ICOs and implement blockchain technology into their business practices using our Zaif exchange and mijin private blockchain software, all at the same time, as a one-stop solution.


Starting with COMSA itself as the first ICO, Tech Bureau, Corp. will launch the token sale on October 2nd, 2017.

This cryptocurrency raised from the token sale will not only fund us to develop the COMSA CORE system and to expand its reach in a rapidly growing ICO market but also to accelerate the growth of its existing core businesses, which are the crypto exchange Zaif and the private blockchain product, mijin.

As part of COMSA’s very own token sale, CMS (COMSA token coin) holders who bought their CMS from COMSA’s token sale exercise will get to enjoy a premium bonus of 5% for every CMS they use to participate in these future ICO campaigns on the COMSA platform.

The token sale will be launched at 14:00 JST on October 2nd, 2017 and closes at 14:00 JST on November 6th, 2017.

5% of CMS tokens will be distributed as referral bonuses to token sale referrals. Sign up today to get your own referral link.

ICO Solution

COMSA is a one-stop solution that includes a creation of multi-language whitepaper, pre-configured token sale dashboard, blockchain integration services and PR services, dedicated for your own ICO. Your ICO token issued on COMSA platform can be converted between NEM and Ethereum blockchain via COMSA CORE engine. (Planned in 2018)

Token Solution

COMSA provides Zaif exchange to list your ICO token, and its payment service to allow your token holders to spend it. We also provide private blockchain software “mijin”, to let you manage tokens in the internal blockchain ledger in your system. We also support fiat pegged tokens and crypto pegged tokens that can be transferred between NEM and Ethereum blockchains.

One-time Smart Contract

In 2018, you will be able to coordinate Bitcoin, NEM, Ethereum and multiple mijin private blockchains as one network to keep the balance of your token among them. We will also offer “network fee delegation” on the NEM blockchain that allows you to process practical business transactions in fiat currency on the blockchain without owning its native currency XEM.


COMSA pre-registration starts on August 3rd, 2017
