Regarding the fact that Coinbase Commerce does not currently support BTC payments on the chain or through the Lightning Network, Coinbase CEO Brian Armstrong responded as follows on the X platform:
“Commerce uses the new EVM payment protocol; users can pay from any self-hosted wallet; believe that payments using cryptocurrencies in the future will primarily occur on L2 and want to help make this happen.
Currently the fastest checkout on Commerce is with any ERC-20 on L2 (Base, Polygon, etc.) including Ethereum, USDC, Wrapped Bitcoin, and hundreds of ERC-20 tokens. As a fallback, customers can make payments using a Coinbase account (if they have one), including paying directly in Bitcoin (Coinbase to Coinbase transactions happen off-chain, so we can make this process instant and free).
We are integrating Lightning Network into Coinbase and hope there will be opportunities to use Lightning Network for commercial payments in the future. Online payments using cryptocurrencies won't truly become mainstream until we move away from Layer 1 and reduce transaction fees and confirmation times, so we're working hard to accelerate to get there. I think the market for people paying for everyday items at Layer 1 will be very small regardless of the chain (except maybe Solana). "
In December last year, Coinbase CEO Brian Armstrong said in an interview that Coinbase plans to integrate Solana. The company hopes that the transaction settlement speed on its platform can be less than one second and the cost is less than one cent. To do this, Armstrong said: “Coinbase will integrate Lightning Network and “other very fast Layer 1s like Solana” on Bitcoin.
