What is WBTC: A Comprehensive Guide to Wrapped Bitcoin 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 interoperability with Ethereum-based decentralized finance (DeFi) applications.

As the first ERC20 token pegged 1:1 to Bitcoin, WBTC plays a crucial role in the DeFi and cross-chain interoperability sectors.

As of 2025, WBTC has become a top 15 cryptocurrency by market capitalization, with a market cap of over $11 billion and an active community of users and developers. This report will analyze its technical architecture, market performance, and future potential.

Origin and Development History

Background of Creation

Wrapped Bitcoin was created by BitGo, Kyber Network, and Ren in 2019, aiming to address Bitcoin's limited functionality within the Ethereum ecosystem.

It was born during the rise of DeFi applications on Ethereum, with the goal of bringing Bitcoin's liquidity and value to the Ethereum network to change the status quo.

WBTC's launch brought new possibilities for Bitcoin holders and Ethereum DeFi users.

Important Milestones

• 2019: Mainnet launch, achieving 1:1 Bitcoin backing with on-chain verification.
• 2020: Major adoption by DeFi protocols, pushing the price and market cap to new heights.
• 2021: Ecosystem explosion, with the number of DeFi protocols utilizing WBTC surpassing 100.
• 2022-2025: Continuous growth in total value locked (TVL) and integration with new DeFi applications.

With the support of the WBTC DAO and community, Wrapped Bitcoin continues to optimize its technology, security, and real-world applications.

How Does Wrapped Bitcoin Work?

No Central Control

WBTC operates on the decentralized Ethereum network, free from control by any single entity like banks or governments. The Ethereum nodes collaborate to validate transactions, ensuring system transparency and attack resistance, giving users greater autonomy and improving network resilience.

Blockchain Core

WBTC utilizes Ethereum's blockchain, which is a public, immutable digital ledger recording 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 transition to Proof-of-Stake, further enhance performance for WBTC transactions.

Ensuring Fairness

WBTC relies on Ethereum's Proof-of-Stake (PoS) consensus mechanism to validate transactions and prevent fraudulent activities like double-spending. Validators maintain network security by staking ETH and running nodes, receiving rewards in ETH. This system provides innovations such as increased energy efficiency and higher transaction throughput.

Secure Transactions

WBTC uses public-private key cryptography to protect 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. Additional security features include the multi-signature approach used in the minting and burning processes of WBTC.

WBTC's Market Performance

Circulation Overview

As of December 15, 2025, WBTC's circulating supply is 124,963.48883569 tokens, which is equal to its total supply. The maximum supply is listed as ∞, indicating no fixed cap.

New WBTC tokens enter the market through a minting process that requires merchant approval and is backed 1:1 by Bitcoin held by custodians.

Price Fluctuations

WBTC reached its all-time high of $125,932 on October 7, 2025, likely driven by broader cryptocurrency market trends 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 that time.

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