solana-program-rosetta

Multiple implementations of Solana programs across languages: Rust, Zig, C, and even assembly.

More programs will be added over time!

Getting started

Prerequisite for all languages

• Install Rust: https://www.rust-lang.org/tools/install

Rust

• Install Solana tools

./install-solana.sh

• Go to a program directory

cd helloworld

• Build a program

cargo build-sbf

• Test a program

cargo test-sbf

Zig

• Get the compiler

./install-solana-zig.sh

• Go to the Zig implementation of a program

cd helloworld/zig

• Build the program

../../solana-zig/zig build

• Test it

cd ..
SBF_OUT_DIR="./zig/zig-out/lib" cargo test

• OR use the helper from the root of this repo to build and test

./test-zig.sh helloworld

C

• Install Solana C compiler

./install-solana-c.sh

• Install Solana tools

./install-solana.sh

• Go to a program directory

cd helloworld/c

• Build a program

make

• Test it

cd ..
SBF_OUT_DIR="./c/out" cargo test

• OR use the helper from the root of this repo to build and test

./test-c.sh helloworld

Assembly

• Install Solana LLVM tools

./install-solana-llvm.sh

• Go to a program directory

cd helloworld/asm

• Build a program

make

• Test it

cd ..
SBF_OUT_DIR="./asm/out" cargo test

• OR use the helper from the root of this repo to build and test

./test-asm.sh helloworld

Current Programs

• Helloworld: logs a static string using the sol_log_ syscall

Language	CU Usage
Rust	105
Zig	105
C	105
Assembly	104

Since this is just doing a syscall, all the languages behave the same. The only difference is that the Assembly version doesn't set the return code to 0, and lets the VM assume it worked.

• Transfer-Lamports: moves lamports from a source account to a destination, with the amount given by a little-endian u64 in instruction data.

Language	CU Usage
Rust	459
Zig	44
C	104
Assembly	31
Rust (pinocchio)	32

This one starts to get interesting since it requires parsing the instruction input. Since the assembly version knows exactly where to find everything, it can be hyper-optimized.

• CPI: allocates a PDA given by the seed "You pass butter" and a bump seed in the instruction data. This requires a call to create_program_address to check the address and invoke_signed to CPI to the system program.

Language	CU Usage
Rust	3662
Zig	2825
C	3122
Rust (pinocchio)	2816
