Coinbase, one of the world's largest cryptocurrency exchanges, recently unveiled its Proof of Reserves (PoR) page for cbBTC (Coinbase’s wrapped Bitcoin). This marks a significant step toward enhancing transparency by verifying Bitcoin reserves backing cbBTC tokens.
The live reserve proof assures users that every issued cbBTC token remains redeemable for actual Bitcoin held by Coinbase.
Understanding cbBTC and Proof of Reserves
cbBTC is a wrapped version of Bitcoin (BTC) issued by Coinbase. Users deposit Bitcoin into Coinbase and receive cbBTC tokens, which can then be transferred across blockchains like Ethereum or Solana. This enables flexible Bitcoin utility without moving native BTC.
With Proof of Reserves, Coinbase demonstrates sufficient Bitcoin reserves to back all circulating cbBTC. For example, at the time of reporting, Coinbase held 26,754 BTC, supporting 26,557 cbBTC—ensuring seamless redemptions.
Why Proof of Reserves Matters
Proof of Reserves is critical in cryptocurrency for:
- Transparency: Validating exchange-held assets.
- Trust: Mitigating solvency concerns post-market crises.
- Security: Guaranteeing redeemability of wrapped tokens.

Coinbase’s move reduces risks for users wary of exchange insolvency, proving adequate reserves for all potential redemptions.
Coinbase’s Strategic Move Amid Competition
"#cbbtc lacks Proof of Reserve, no audits, and can freeze balances anytime. Essentially, it’s 'trust me.' Any U.S. subpoena could seize your BTC."
— Justin Sun (@justinsuntron)
In December, Coinbase delisted WBTC (Wrapped Bitcoin) after its custodian partnered with Justin Sun-affiliated entities. This underscores Coinbase’s commitment to platform integrity by supporting only verifiable tokens.
By pioneering PoR for cbBTC, Coinbase aims to lead in crypto transparency, setting a benchmark for other platforms to prove asset reserves and bolster global user trust.
