Sophon, which has raised a total of $70 million, announced the closure of its own Layer 2 blockchain and migration to Base, with a focus on consumer application development in the future. Sophon stated that continuing to invest $2 million annually to maintain its own chain is no longer reasonable. Co founder Sebastien stated that the value of the project lies in building the product rather than running the underlying track. Sophon will no longer maintain infrastructure and is expected to reduce annual consumption by approximately $3 million after closing its own chain, while investing more capital in application development.
