PANews reported on September 23 that 0xngmi, founder of DefiLlama, posted on the X platform that almost all cross-chain bridges (including WBTC) provide proof of reserve (PoR) to ensure that the issued tokens have sufficient asset support, but Coinbase's cbBTC lacks transparency and does not provide PoR. He also pointed out that because of this, DefiLlama has not yet included cbBTC on the platform because its locked volume (TVL) cannot be verified, and emphasized that DefiLlama treats all projects equally and will not make an exception for Coinbase.
