Anchor v2 is the new foundation for Solana programs.
Anchor v2 gives you a Rust framework for writing Solana programs, checking accounts safely, generating IDLs and client code, and testing everything from one workspace.
Scroll for moreOne framework, one program loop
Write programs with the workflow you know, backed by a leaner runtime, clearer account types, generated IDLs, and first-class tests.
Account validation
Define account requirements declaratively and reject bad inputs before handlers run.
IDLs and generated clients
Describe your program once and generate typed client surfaces.
A complete workspace loop
Scaffold programs, build artifacts, run tests, and deploy from one CLI.
Composable Solana programs
CPI helpers, SPL integrations, and generated account metadata make programs easier to connect.
Anchor v2 in practice
Anchor v2 keeps the workflow developers rely on while making the generated program smaller, lighter, and cheaper to run.
Start where you are
Whether you are learning Anchor, moving a v1 program, or deciding if v2 is ready, start from the path closest to your code.
