TBD

Open-source developer platform and protocols for decentralized finance and Bitcoin

by block · Treasury & Cash Management

Executive Summary

TBD was an initiative by Block (formerly Square) focused on building open-source decentralized financial services, primarily centered around Bitcoin. Its mission was to create a platform and developer infrastructure to enable broader access to the global economy, including a protocol for on- and off-ramps from fiat to digital currencies, particularly for the unbanked. However, Block announced in its Q3 2024 Shareholder Letter that it is winding down TBD, indicating a cessation of active development and investment in the project.
