Coinbase Wrapped BTC, or cbbtc, is an ERC-20 token that represents Bitcoin on the Ethereum blockchain. Each cbbtc is backed 1:1 by actual BTC held in custody by Coinbase. This enables Bitcoin holders to use BTC in Ethereum-based ecosystems, including decentralized finance (DeFi) protocols, lending platforms, and programmable smart contracts, without selling their BTC. To convert BTC to cbbtc, you lock BTC with Coinbase and receive the equivalent amount of cbbtc, and vice versa for redeeming. This wrapping enables BTC liquidity and cross-chain utility within Ethereum-native applications.

How can I buy, store, and redeem cbbtc safely?

To buy or redeem cbbtc, you typically use Coinbase or compatible platforms that support the token. When you hold cbbtc, store it in a compatible Ethereum wallet (e.g., MetaMask, Coinbase Wallet) that supports ERC-20 tokens. For added security, use hardware wallets like Ledger when holding larger amounts. Redeeming cbbtc for BTC requires sending your cbbtc back to Coinbase (or through the supported bridge) to unlock and withdraw the equivalent BTC to your Bitcoin wallet. Always verify contract addresses and use reputable platforms to minimize counterparty risk and avoid phishing attempts.

What are the risks and considerations of using cbbtc in DeFi?

Using cbbtc in DeFi exposes you to both typical Ethereum risks and counterparty risk related to the BTC backing. Potential risks include smart contract bugs, liquidity risk in pools or lending protocols, and fees from gas on Ethereum. Although CB’s BTC backing aims for 1:1 parity, on-chain failures or custody issues could affect redemption. Monitor the token’s peg status, check official disclosures from Coinbase, and diversify across platforms. If you’re unsure, start with small amounts and use reputable, audited contracts or pools.

How does the price of cbbtc relate to Bitcoin and BTC on Ethereum?

cbbtc is designed to track the price of Bitcoin, but its value is expressed in USD as an ERC-20 token on Ethereum. The token’s price should closely mirror BTC’s price, adjusted for minor deviations and gas costs. When BTC moves, cbbtc typically follows, since it’s backed 1:1 by BTC held in custody. However, market dynamics, liquidity on Ethereum-based platforms, and arbitrage opportunities can create small price discrepancies. Investors should compare cbbtc charts with BTC/USD and BTC/ETH trading pairs to understand relative pricing and potential slippage in swaps.

What are the current fundamentals for cbbtc (supply, market cap, and liquidity)?

As of the latest data, cbbtc has a circulating supply of about 77,215 tokens and a market capitalization around $6.94 billion. The current price is approximately $89,688, with a 24-hour price movement of about -1.98%. Liquidity varies by exchange and DeFi protocol, so traders should check on-ramps and liquidity pools on Ethereum-based decentralized exchanges (DEXes) or centralized platforms that support cbbtc. Always review the latest on-chain data, custody disclosures, and platform liquidity before large trades, and consider the impact of gas fees on profitability.
