FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

solana-pubkey

Latest Version on Packagist run-tests PHPStan Total Downloads

Tiny, framework-agnostic PHP library for Solana public keys and Ed25519 signature verification.

Built for Sign-In With Solana flows where you need to validate a wallet address and verify a detached signature — without pulling in a full Solana SDK.

Installation

Requires PHP 8.3+ and ext-sodium. No other runtime dependencies.

Usage

Verify a Solana wallet signature

Construct from raw bytes

Base58 encoding

API surface

See PUBLIC_API.md for the SemVer-governed surface. Anything not listed there is @internal and may change in any release.

Exceptions

All thrown exceptions extend SanderMuller\SolanaPubkey\Exceptions\SolanaPubkeyException (which extends RuntimeException):

Exception Thrown by
InvalidPublicKeyException PublicKey::from(), PublicKey::fromBytes() — wrong length or invalid base58
InvalidBase58Exception Base58::decode() — non-alphabet character
InvalidSignatureException PublicKey::verify() — signature is not exactly 64 bytes

PublicKey::verify() returns false (does not throw) for wrong-but-well-formed signatures and tampered messages.

Why this exists

The collectiq/solana-php-sdk is a full Solana SDK (RPC, transactions, Borsh, programs, DID). For SIWS-style auth flows, you only need three primitives: base58 codec, Ed25519 verify, and pubkey validation. This package ships exactly those, with no framework dependencies and no proprietary-license upstream.
