Birdai Labs completes a $4 million seed round, led by Castle Island Ventures

Deep Tide TechFlow message: On July 28, Birdai Labs announced the completion of a $4 million seed round. The round was led by Castle Island Ventures, with participation from Metalayer Ventures and The Venture Dept. The company focuses on building neutral infrastructure for on-chain transaction execution—used to measure, validate, and improve transaction execution quality on high-performance blockchains—while increasing market transparency and returning some of the value to participants that generate transaction flow.

The funds from this round will be mainly used to recruit senior engineering talent and expand the company’s infrastructure footprint at the chain’s underlying layer. Birdai Labs believes that as multi-proposer architecture gradually becomes an industry trend and transaction ordering rights become further distributed, execution quality is becoming a key dimension for competition in on-chain markets.
