What is WBTC: Understanding the Wrapped Bitcoin Token and Its Role in DeFi

Wrapped Bitcoin's Positioning and Significance

In 2019, BitGo, Kyber Network, and Ren jointly launched Wrapped Bitcoin (WBTC), aiming to solve the issue of Bitcoin's limited functionality on Ethereum and other smart contract platforms.

As the first ERC20 token pegged 1:1 to Bitcoin, WBTC plays a crucial role in the DeFi ecosystem, enabling Bitcoin holders to participate in Ethereum-based decentralized finance applications.

As of 2025, WBTC has become a core asset in the DeFi space, with a market capitalization of over $12 billion and 144,048 holders. This report will analyze its technical architecture, market performance, and future potential.

Origin and Development History

Birth Background

Wrapped Bitcoin was created by a consortium including BitGo, Kyber Network, and Ren in 2019, aiming to address the lack of Bitcoin's interoperability with Ethereum-based DeFi protocols.

It was born during the rise of decentralized finance, with the goal of bringing Bitcoin's liquidity and value to the Ethereum ecosystem through a transparent and verifiable wrapping process.

WBTC's launch opened new possibilities for Bitcoin holders to participate in yield farming, lending, and other DeFi activities on Ethereum.

Important Milestones

• 2019: Mainnet launch, achieving 1:1 Bitcoin backing with on-chain verification.
• 2020: Rapid adoption in DeFi protocols, driving price and usage growth.
• 2021: Total value locked (TVL) in WBTC surpasses 1% of Bitcoin's market cap.
• 2025: Ecosystem expansion, with WBTC integration in hundreds of DeFi platforms.

With support from the WBTC DAO and custodians, Wrapped Bitcoin continues to optimize its security, transparency, and real-world applications in the DeFi space.

How Does Wrapped Bitcoin Work?

Decentralized Control

While WBTC operates on the Ethereum network, its minting and burning processes involve multiple parties to ensure decentralization and security.

Merchants initiate minting or burning requests, custodians hold the underlying Bitcoin, and the DAO oversees the entire process, creating a system of checks and balances.

Blockchain Core

WBTC leverages Ethereum's blockchain, a public and immutable digital ledger that records every transaction.

Transactions are grouped into blocks and linked through cryptographic hashes, forming a secure chain.

Anyone can view the records, establishing trust without intermediaries.

Ethereum's upgrades, such as the shift to Proof-of-Stake, further enhance WBTC's performance and efficiency.

Ensuring Fairness

WBTC utilizes Ethereum's consensus mechanism (currently Proof-of-Stake) for transaction validation and prevention of fraudulent activities.

Validators stake ETH to maintain network security and process WBTC transactions, receiving rewards in ETH.

This system provides enhanced energy efficiency and higher transaction throughput compared to Bitcoin's Proof-of-Work.

Secure Transactions

WBTC uses public-private key cryptography to secure transactions:

• Private keys (like secret passwords) are used to sign transactions
• Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security, while transactions remain pseudonymous on the Ethereum blockchain.

Additionally, WBTC implements a transparent custodial system with regular proof-of-reserve audits to verify the 1:1 backing of each WBTC token with actual Bitcoin.

WBTC's Market Performance

Circulation Overview

As of November 14, 2025, WBTC's circulating supply is 126,763.48883569 tokens, which is equal to its total supply of 126,763.48883569. This indicates a fixed supply model.

New WBTC tokens enter the market through a minting process controlled by custodians with merchant approval, directly impacting its supply and demand dynamics.

Price Fluctuations

WBTC reached its all-time high of $125,932 on October 7, 2025, likely driven by overall market bullishness and increased institutional adoption of Bitcoin-pegged assets.

Its lowest price was $3,139.17, recorded on April 2, 2019, possibly due to the early stages of the project and lower Bitcoin prices at the time.

These fluctuations reflect market sentiment, adoption trends, and external factors affecting both WBTC and the underlying Bitcoin.
