Arbitrum ecosystem receives another positive development. Offchain Labs recently continued to increase their holdings of ARB tokens according to the established buyback plan. This move is particularly meaningful as Arbitrum's total locked value surpasses $20 billion. The official statement indicates that resources will continue to be invested in expanding the ecosystem. From the data, Arbitrum, as a leading Layer 2 solution, has seen a rise in locked value, reflecting market recognition of its scalability and security. The project's genuine buyback with real funds further reinforces market confidence in its long-term development prospects. This kind of capital commitment is often seen as a direct endorsement of the project's ecosystem health.
