40 m, the shell exchange

Rent a shell

Hermit crabs line up by size and wait for the shell that fits. Pick what you want to run, Shello finds the GPU shell that holds it, and your own wallet rents it on Nosana.

What this is

A GPU you rent by the hour on Nosana's network, paid in NOS from your own wallet: a chat model endpoint, image generation, or a Jupyter notebook. Shello is not part of Nosana and takes no fee.

How it works

Choose what runs and for how long. Prices are Nosana's, read live from the chain.
Shello builds the transaction, reads it back, and simulates it on Solana so you see what moves before you sign.
A GPU node picks the job up. Unused time is refunded by Nosana's program. Manage it in My shells.

What you sign

Sign in signs a text message. It is not a transaction and costs nothing.
Rent signs a real Solana transaction that moves NOS from your wallet into Nosana's program. You see every amount first, measured by a simulation just before your wallet opens.
Shello never asks for a seed phrase or private key, and never holds your NOS.

Before you trust it

Shello never holds your NOS, SOL or keys. Your wallet pays Nosana directly.
Nosana runs the GPU, not Shello. We don't guarantee uptime; jobs can fail or queue.
Unused time is refunded by Nosana's program; a small SOL deposit returns when you close the job.
Your endpoint is protected by a key only you hold. Keep it private.
Not audited yet. Rentals are capped at $25 per transaction.
Software, not advice.

Locked with an access key made in your browser. Shello and Nosana see only its hash. Every request needs it: Authorization: Bearer <key>.

4Check before you sign

No Solana wallet found in this browser. Phantom, Solflare, Backpack and OKX Wallet can sign in; on a phone, use the wallet button at the top to open Shello inside your wallet app. You do not need a wallet for anything free on Shello.

Signing in signs a short text message: "Sign in to Shello. This does not send a transaction or cost anything." Shello never asks for a seed phrase or private key.

5Sign with your wallet

Your wallet shows a Nosana transaction from your own address. Signing it pays the deposit straight into Nosana's program.
