Thank you for this detailed contribution. As far as I can judge, I'm pleased with Terablock's interest in the Hive Blockchain. As mentioned in the post, your product is already in daily operation in a prominent DApp on Hive, namely Splinterlands. I also view a successful and well-maintained bridge with the main tokens HIVE and HBD as highly valuable (assuming we're talking about the main tokens and not second-layer solutions like Hive Engine, etc.).
However, what surprises me is the need for an upfront grant from the Hive community. Your services, bridges, and swaps are not free, I assume that you'll be charging fees after implementation. Here, I see the risk being shifted onto the community.
As you've demonstrated with Splinterlands, you've been able to generate substantial revenue from fees. That should be motivation enough to include HIVE/HBD as tokens and as part of the blockchain.
Moreover, if this were an open-source protocol that could be maintained by the community post-development, I could understand better. For a closed-source system, this seems a bit too much to spend.
As a final point, I'm curious about how you plan to attract sufficient liquidity. As far as I understand, there's no way for users to participate in the pool. Or am I misunderstanding this? Can an external liquidity provider also participate? This would be very interesting if, by holding your tokens, one could support the protocol and potentially earn a share of the fees.
