cbBTC vs WBTC vs tBTC: Which Wrapped Bitcoin?

cbBTC, WBTC and tBTC are all tokens backed 1:1 by bitcoin. What separates them is who holds the BTC. Coinbase holds cbBTC's reserves. WBTC sits with BitGo under a joint venture with BiT Global. tBTC is controlled by 100 node operators, any 51 of whom must sign. If you don't need DeFi, native BTC avoids all three risks.

Wrapped bitcoin exists because Bitcoin can't run Ethereum-style smart contracts. To use BTC as collateral, liquidity or a trading pair on Ethereum, Base or Solana, someone has to lock real bitcoin and issue a token that represents it. The way that "someone" is set up decides what you're trusting. Here's how the three main options compare as of October 2026.

WBTC: the incumbent, and the 2024 custody change

Wrapped Bitcoin went live on Ethereum on January 31, 2019, as a joint project of BitGo, Kyber Network and Republic Protocol (later Ren), with BitGo as custodian. The design is simple. Approved merchants send BTC to the custodian and receive WBTC, or burn WBTC to get BTC back. WBTC's site says only identity-verified institutions approved through DAO governance can mint and burn, and it lists merchants including Galaxy, Amber Group, BitGo, Wintermute, CoinList and Cobo. Everyone else gets WBTC on the market.

On August 9, 2024, BitGo announced it would move its WBTC business into a joint venture with BiT Global, a Hong Kong-registered trust company. The custody of the backing BTC would spread across several jurisdictions, including Hong Kong and Singapore, after a 60-day transition. BitGo said it would hold a minority stake and that the same multisig and cold-storage technology would remain in place. BiT Global's ties to Justin Sun drew criticism. Aave's risk contributors debated the change in governance: Chaos Labs called an immediate risk-off move premature, and LlamaRisk sought legal clarification on the new structure.

On November 19, 2024, Coinbase announced it would suspend WBTC trading on December 19, saying the token no longer met its listing standards. It didn't say which standards. BiT Global later sued Coinbase over the delisting. WBTC's site still describes each token as backed 1:1 and verifiable through on-chain proof of reserves. The episode showed that a custodial wrapper's risk includes who runs the custodian.

cbBTC: Coinbase's wrapper

Coinbase launched Coinbase Wrapped BTC (cbBTC) on September 12, 2024, as an ERC-20 on Ethereum and Base, backed 1:1 by bitcoin Coinbase holds. It doesn't have a separate trading pair on the exchange. Instead, Coinbase customers in supported regions send BTC from their account to a Base or Ethereum address and receive cbBTC 1:1. Sending cbBTC back to a Coinbase account converts it to BTC. On-chain, anyone can hold and transfer it. cbBTC launched on Solana as an SPL token on November 7, 2024.

At launch, DeFi integrations included Aave, Compound and Morpho for lending and Aerodrome and Curve for trading. Transparency was the early criticism. DefiLlama's developer said cbBTC fell below the standard set by other wrappers, and Coinbase said proof of reserves was on its roadmap. In April 2025, Chainlink listed cbBTC on Base among assets that use Chainlink Proof of Reserve.

The trade-off is plain: cbBTC's risk is concentrated in one large, regulated company, and direct redemption goes through a Coinbase account.

tBTC: the threshold-signer approach

tBTC, from the Threshold Network, replaces the custodian with cryptography and a set of operators. Threshold says deposited bitcoin is controlled by 100 node operators and that any 51 of them can jointly authorize a transaction. No single operator or small group holds a full private key, and the signer set is chosen by stake and rotated over time.

The current version launched on January 31, 2023, initially using "optimistic minting." A permissioned group of Minters watched for BTC deposits, and Guardians could cancel suspicious mints. Threshold now describes minting and redemption as permissionless through its app. Its docs list a 0.2% fee for each. The mint fee was waived for a while and reinstated on April 15, 2026, by governance, and staking T can partly or fully offset these fees.

tBTC is native to Ethereum and reaches other chains through bridges such as Portal and StarkGate, so its versions on Solana or Starknet add that bridge's risk on top. Its security rests on an honest majority of signers rather than one company.

Redemption: getting back to real BTC

A wrapper is only as good as the exit. Here's what redeeming each one involves:

	Direct redemption	Everyone else
WBTC	Approved merchants burn WBTC and receive BTC from the custodian	Sell WBTC on a DEX, or swap it cross-chain for native BTC
cbBTC	Send cbBTC to your Coinbase account, where it converts to BTC	Sell on a DEX, or swap cross-chain
tBTC	Redeem through the Threshold app to a Bitcoin address (0.2% fee)	Same permissionless path, or sell on a DEX

If you can't redeem directly, the price you get depends on DEX liquidity and on whether the market trusts the backing. That's when the custodian question stops being theoretical.

Where each one can fail

Risk	WBTC	cbBTC	tBTC
Key compromise	Custodian multisig keys spread across jurisdictions	Coinbase's custody systems	51 of 100 operators would have to collude or be compromised
Legal or corporate	Joint-venture structure and its jurisdictions	One company's policies and regulators	Governance decisions, such as fee changes
Exit dependency	A small set of approved merchants	A Coinbase account in a supported region	The Threshold app and signer liveness
Extra layers off the home chain	Varies by network	Issued directly on Ethereum, Base and Solana	Bridges for every chain except Ethereum

No column is risk-free. The right question is which failure you're more comfortable with: a company, a joint venture, or a decentralized signer set.

Which chains and DeFi apps support them?

Support depends on the chain. All three have DeFi integrations. Chainlink's April 2025 overview called WBTC the largest wrapped bitcoin by market capitalization. On Base, cbBTC is Coinbase's native issuance. If you're moving funds onto that network, our Base bridge shows live routes. On Solana, cbBTC is an SPL token issued directly by Coinbase, while tBTC there arrives through a bridge. Before you deposit, check which version a lending market or pool actually accepts. A bridged token with the same name won't necessarily count.

Quick answers

What is cbBTC?

cbBTC is Coinbase Wrapped BTC, a token on Ethereum, Base and Solana backed 1:1 by bitcoin that Coinbase holds. Coinbase customers in supported regions can convert between BTC and cbBTC through their account.

What is tBTC?

tBTC is the Threshold Network's bitcoin token, minted on Ethereum against BTC controlled by a rotating group of 100 signers, where 51 must agree to move funds.

Is cbBTC better than WBTC?

Neither is strictly better. cbBTC concentrates trust in Coinbase. WBTC relies on a multi-party custody arrangement and a merchant network. Choose based on which exit you can actually use.

When to hold native BTC instead

All three tokens add risk that plain bitcoin doesn't have: custodian or signer failure, smart contract bugs, bridge exposure, and redemption limits. If your bitcoin is a long-term holding rather than DeFi collateral, native BTC in a self-custody wallet avoids all of it. Our explainer on native vs wrapped crypto covers the trade-offs in more detail.

A simple decision guide:

• Holding BTC for the long term: native BTC.
• Using DeFi on Base, or already a Coinbase customer: cbBTC, with the most direct exit through Coinbase.
• Want the oldest wrapper: WBTC, live since 2019 and the largest by market cap in Chainlink's April 2025 overview, if you accept the custody structure.
• Want permissionless minting and redemption without a single custodian: tBTC, accepting threshold-signer and bridge risk.

Whichever you choose, keep position sizes in line with your trust in the issuer, and don't assume two tokens with "BTC" in the name are interchangeable inside a protocol.
