SXG is a Solana-based service that connects the yield from staked SOL with access to real GPU computing. Users deposit SOL into their own vault on Solana; the principal remains theirs and can be withdrawn at any time. According to SXG, only the yield earned by the staked SOL is used to pay for GPU time, so users do not spend their deposited SOL to run workloads.

The service offers access to real NVIDIA RTX 4090 GPUs for generating images from text and using a Python workspace. New users receive their first three minutes of GPU access free. SXG provides an interactive rack interface for exploring and selecting GPUs, and users can connect a Solana wallet, such as Phantom or Solflare, to get started. Wallet verification requires signing a message, with the site stating that this does not involve a transaction or network fee. SXG presents its offering as a way to use GPU computing while keeping control of the SOL held in a personal Solana vault.
