Market rumors suggest that PTB, a Bitcoin ecosystem project previously listed on Binance Alpha in September, may be preparing for a listing on Coinbase. This article revisits the PTB project and evaluates the feasibility of its potential Coinbase debut.

PTB Project Overview

PTB (Portal To Bitcoin) is dedicated to addressing core pain points in the "Bitcoin cross-chain + Bitcoin DeFi" space, positioning itself as a unified entry protocol for the Bitcoin ecosystem. It enables seamless access to Bitcoin assets across other blockchains, facilitating fast, low-cost atomic swaps between native Bitcoin assets—such as BTC, Ordinals, and Runes—and Layer 2 solutions or alternative Layer 1 networks. By leveraging peer-to-peer, on-chain verifiable smart contracts, PTB aims to eliminate the security risks traditionally associated with cross-chain bridges.

Funding Status:

According to RootData data, the project was founded in 2019 and has completed three funding rounds, with the latest round concluded in August 2025.

1. 2021 Round: $8.5M, first-round valuation near $100M;
2. 2024 Round: $34M;
3. August 2025 Round: $50M;
4. Investors include Coinbase Ventures, OKX Ventures, and others.

Opportunities and Risks

Opportunity Highlights:
Given the current unfavorable macro capital environment, the project appears significantly undervalued. Even compared to the initial fundraising valuation of $100M in the first round, the current fully diluted market cap stands at just $54M. When contrasted with the latest round’s implied valuation of $1B, the discrepancy becomes even more pronounced.

Risk Factors

• Project remains in early stage; ecosystem not yet fully matured
• Coinbase listing remains speculative—progress must be monitored closely
• Bitcoin DeFi narrative is still evolving, facing intense competition
• Second and third-round funding details raise skepticism, particularly the $1B valuation disclosed just one month before Binance Alpha listing—authenticity requires rigorous due diligence
