Want to use your Bitcoin in Base’s DeFi ecosystem without selling your BTC? That’s exactly what cbBTC is for — a wrapped version of Bitcoin that lives on Base (and Ethereum), backed 1:1 by real bitcoin held in custody.
This guide walks you through 7 steps to get cbBTC onto Base in 2026, plus the risks you should understand before you start.
id=”what-cbbtc-is”>What cbBTC Is
cbBTC is Coinbase’s wrapped Bitcoin token. Each cbBTC is backed by one bitcoin held by Coinbase, and you can convert between BTC and cbBTC through your Coinbase account. On Base, cbBTC behaves like any other ERC-20 token: you can hold it, swap it, or use it in DeFi apps — all while your exposure tracks bitcoin’s price.
The key thing to understand: cbBTC is an IOU, not native bitcoin. Its value depends on Coinbase’s custody and backing. If you want pure, self-custodied bitcoin with no intermediary, keep BTC on the Bitcoin network instead.
7 Steps to Get cbBTC on Base
Step 1: Set up a wallet that supports the Base network (Chain ID 8453) and back up your seed phrase offline. Step 2: Make sure you have BTC — either in your Coinbase account or purchased there. Step 3: On Coinbase, convert your BTC to cbBTC (or buy cbBTC directly where available). Step 4: Withdraw the cbBTC from Coinbase, selecting the Base network as the destination — choosing the wrong network can lose your funds. Step 5: Paste your Base wallet address carefully, verifying the first and last characters. Step 6: Confirm the withdrawal and wait for it to arrive (usually minutes). Step 7: In your wallet, import the cbBTC token if it doesn’t display automatically, and verify the balance.
Risks and Costs to Know
You’ll pay Coinbase’s conversion/spread and withdrawal fee, plus you need a little ETH on Base for gas when using cbBTC afterward. The bigger consideration is trust: cbBTC depends on a single custodian, unlike native BTC. That’s a trade-off — convenience and DeFi access in exchange for counterparty risk.

The Bottom Line
Getting cbBTC onto Base is simplest via Coinbase: convert BTC to cbBTC, withdraw to the Base network, and verify. Just remember you’re trading self-custody for convenience — and always double-check the withdrawal network.
