ed25519-gpu-vanity

A CUDA-based miner for finding ED25519 vanity public keys (encoded as Solana Base58 addresses) ending with a specific suffix (default: "pump").

Warning: Keys generated by this tool are NOT SECURE and should not be used for any sensitive applications. Use at your own risk. Note: Base58 encoding on the GPU is less efficient than hex encoding. Expect lower keys/second compared to typical hex vanity address generators.

Building

Ensure CUDA binaries are in your PATH:

export PATH=/usr/local/cuda/bin:$PATH # Adjust path if necessary
make -j$(nproc)

Running

LD_LIBRARY_PATH=./src/release ./src/release/cuda_ed25519_vanity

Configuration

You can adjust the search parameters by editing the src/config.h file and recompiling the project using make.

Key configuration options include:

• suffix: Change the target suffix string (default: "pump"). Remember to keep it reasonably short for faster searching.
• STOP_AFTER_KEYS_FOUND: Set how many matching keys should be found before the program stops (default: 100).
• MAX_ITERATIONS: Limits the total number of iterations the program runs (default: 100000). This acts as a failsafe or time limit.

After modifying src/config.h, rebuild the project:

make clean && make -j$(nproc)

Output

Found keys are collected from the GPU(s) and printed by the host process. Host-side Base58 encoding is used to display the final keys.

When a matching key is found, the output will look like this:

--- MATCH FOUND (GPU <gpu_id>) ---
Public (Base58): [<Base58_public_key_ending_in_suffix>]
Secret (Base58): [<Base58_encoded_64_byte_private_key>]
--------------------------

• The Public (Base58) key (e.g., ...pump) is the Solana vanity address.
• The Secret (Base58) key is the 64-byte expanded private key compatible with Solana wallets (e.g., Phantom allows importing via this format).

Note: The Base58 encoding of the public key (which determines the suffix match) is performed on the GPU during the search. The host then re-encodes the raw keys found using Base58 for display.
