Bitcoin is a Tier-1 protocol at Coinbase, reflecting its foundational importance to our strategy and the broader crypto economy. Our approach to supporting the network is focusing on three key pillars: its Core Protocol (L1), its function as a premier Asset (BTC), and its potential as an Innovation Layer.
This report details the key initiatives we've launched to execute on this strategy, organized into two main areas that support these pillars.
First, we explore how we are Building the Future of Finance with Bitcoin. These efforts, which support our "Asset" and "Innovation Layer" pillars, leverage Bitcoin as a foundational asset for new products. This suite of offerings includes cbBTC, and Bitcoin-backed loans. Beyond advanced DeFi products, we are also bringing Bitcoin into everyday spending - the Coinbase Card, which is designed to unlock new uses and broaden adoption.
Second, we detail our Protocol-Level Enhancements. This work supports our "Core Protocol (L1)" pillar and is designed to make Bitcoin more efficient, reliable, and scalable. These enhancements include our new, mempool-aware fee estimation service and our support for the Lightning Network.
Building on these core protocol enhancements, Coinbase is leveraging Bitcoin as a new tool for financial products. These offerings are designed to connect the crypto economy with everyday finance, creating real value for our users.
Coinbase Wrapped BTC (cbBTC) is our solution for bringing Bitcoin's deep liquidity into the decentralized finance (DeFi) ecosystem. By making Bitcoin compatible with applications on Base, Ethereum, Arbitrum and Solana, cbBTC unlocks its potential as a productive asset. Since launching in late 2024, adoption has grown consistently. The total supply now exceeds 68,000 BTC with a market capitalization of over $8.2 billion1 as of October 2025. This growth is further evidenced by a rapidly expanding user base, with the number of daily cbBTC holders surpassing 516,000 across multiple chains.

Our onchain Bitcoin-backed loans product on Coinbase allows users to unlock the value of their Bitcoin without the need to sell. By collateralizing their cbBTC, customers can borrow USDC directly onchain via the Morpho protocol on Base, providing instant liquidity while retaining their long-term investment. This streamlined process requires no credit checks or lengthy applications, offering a capital-efficient way to access funds. The product has seen significant traction, with onchain borrow originations surging to over $1B2 by October 2025. This strong market demand validates our strategy of building an integrated financial ecosystem where a user's Bitcoin can serve as productive collateral.
The volume of onchain borrow originations has grown significantly, highlighting the demand for Bitcoin-backed loans.
The Coinbase One Card seamlessly integrates Bitcoin into the daily financial lives of our users. Offered exclusively to Coinbase One members, the card provides an industry-leading 4% back in Bitcoin on all purchases. With no annual fees and the ability to spend directly from a Coinbase cash balance, this premium reward structure transforms everyday spending into a powerful tool for accumulating Bitcoin. This creates a positive cycle of earning, spending, and saving within our ecosystem, reinforcing the value of our membership and driving the utility of crypto in everyday life.
Coinbase is committed to improving Bitcoin's core capability at our services, focusing on initiatives that enhance its utility, scalability, and day-to-day efficiency. These efforts are crucial for making Bitcoin a more practical and reliable medium for payments by directly addressing key challenges like network congestion and transaction costs.
To navigate the complexities of Bitcoin's dynamic fee market, Coinbase has deployed an advanced, mempool-aware fee estimation service. This system analyzes real-time, mempool data to provide more accurate and reliable fee predictions than legacy methods. This enhancement directly benefits our retail customers by focusing on responsiveness. It ensures they pay the minimum fee possible while dramatically improving reliability, boosting our next-block transaction landing rate from 75% to 99%. This system also delivers substantial cost savings by avoiding persistent high estimates after congestion. Internal analysis shows the new service has prevented an estimated $9 million in potential overpayments over the last twelve months and is saving an additional $1 million annually on Custody transfers alone. The chart shows that the mempool-aware fee estimation rapidly reacts to both spikes and relaxations in congestion.

To address the need for faster and more affordable Bitcoin transactions, Coinbase has integrated the Lightning Network for our retail users. This Layer 2 solution provides an efficient, near-instant alternative to onchain transactions, reducing transfer costs by over 80%. This translates to an estimated annual savings for our users of between $2.6 million and $21.7 million, depending on network congestion and the price of Bitcoin. This level of weekly activity, reaching approximately 26,000 receives and 18,000 sends, confirms that the Lightning Network remains a vital component of our strategy to make Bitcoin a practical medium for payments.

Bitcoin stands as a foundational pillar of the crypto economy at Coinbase. The initiatives detailed in this report are not isolated improvements; they represent a comprehensive execution of our three-pillar strategy.
We remain committed to leading this charge, building the infrastructure, and delivering the products that will unlock Bitcoin's full potential for generations to come.
