Coinbase Wrapped BTC (CBBTC) is an ERC-20 token on Ethereum that tracks the value of Bitcoin, allowing BTC exposure to move within the Ethereum ecosystem. Traders commonly swap CBBTC to access Ethereum-based DeFi protocols without selling their Bitcoin position, or swap out of CBBTC back toward native BTC or stablecoins when exiting those positions. Because CBBTC lives on Ethereum, it inherits that network's settlement characteristics and gas fee structure.
Exchange Coinbase Wrapped BTC
Before exchanging Coinbase Wrapped BTC
Before swapping CBBTC, confirm that both your sending and receiving addresses are Ethereum-compatible ERC-20 addresses — CBBTC is not available on any other network. Ethereum confirmation times can vary depending on network congestion, so factor that into your timing. No memo or destination tag is required for CBBTC transactions. The Zest widget displays the rate and estimated output before you confirm, so review those figures carefully, especially during periods of Ethereum network activity that could affect gas costs.

Frequently Asked Questions
CBBTC is an ERC-20 token on Ethereum, so you need a standard Ethereum address (0x…) for both the source and destination. Sending CBBTC to a non-Ethereum address will result in permanent loss of funds, so double-check compatibility with the receiving wallet before confirming.
CBBTC is issued by Coinbase and backed by BTC held in Coinbase custody, making it distinct from other wrapped BTC variants issued by different entities. The key practical difference when swapping is that CBBTC operates solely on Ethereum, whereas some other wrapped Bitcoin tokens exist on multiple networks. Always verify which specific wrapped BTC token your destination platform or protocol accepts.
Minimums vary by pair and network. The exchange widget shows the exact minimum and maximum for your selected pair before you confirm, so you can check the limits before sending anything.
No signup is required for standard swaps. Zest is non-custodial: you send from and receive to wallets you control, and the rate is shown before you confirm.
