Rent out your GPU

Any Linux machine with a supported NVIDIA GPU can join the marketplace. The Gysga agent runs renters’ containers, reports your GPUs and keeps an outgoing tunnel to the platform — you don’t open any ports.

Requirements

Section titled “Requirements”
  • OS: Ubuntu 22.04 or 24.04, x86_64, with systemd.
  • GPU: one or more supported NVIDIA GPUs of the same model in one machine (see below).
  • NVIDIA driver 570 or newer (the current templates need CUDA 12.8–12.9; older drivers get fewer renters because templates with a higher CUDA requirement skip the machine).
  • Docker and the NVIDIA Container Toolkit (docker run --gpus all nvidia/cuda:12.8.1-base-ubuntu24.04 nvidia-smi must work).
  • Disk: 100+ GB free on the partition with /var/lib/gysga (images, models and renters’ /workspace live there). More disk = more templates and larger models fit.
  • RAM: at least 16 GB per GPU is recommended. CPU cores and 90% of RAM are shared between renters in proportion to their GPUs.
  • Network: a stable connection; 100+ Mbit/s recommended for downloading models. No public IP or open ports needed.
  • The machine should be dedicated: renters get the GPUs exclusively while their servers run.

Supported GPUs

Section titled “Supported GPUs”

RTX 3060 (12 GB), 3080 Ti, 3090, 4060 Ti 16GB, 4070 Ti SUPER, 4080 / SUPER, 4090, 5070 Ti, 5080, 5090; RTX A4000, A5000, A6000, RTX 6000 Ada, RTX PRO 6000 Blackwell; A10, A40, L4, L40, L40S, A100 40/80GB, H100, H200, B200. Laptop GPUs and cards with less memory than listed are not accepted. Renters pay the fixed price of your GPU model.

Install

Section titled “Install”
  1. In the dashboard open Rent out your GPU → Add machine. You get a one-time install command; its token is valid for 24 hours and registers one machine.
  2. Run it on the machine:
Terminal window
curl -fsSL https://get.gysga.com | sudo sh -s -- <token>

The installer:

  • checks the OS, the NVIDIA driver, Docker and the NVIDIA Container Toolkit;
  • downloads the gysga-agent binary;
  • writes its configuration to /etc/gysga/ (the machine’s credentials are stored in /etc/gysga/machine.json, readable by root only);
  • installs and starts the gysga-agent systemd service.

On start the agent:

  • creates the Docker network gysga (10.231.0.0/16, no traffic between containers, no IPv6);
  • adds firewall chains GYSGA-FWD and GYSGA-IN (iptables) that block containers from reaching your LAN, private address ranges, cloud metadata, the host itself and outgoing SMTP;
  • stores data in /var/lib/gysga (models/ — model cache, instances/ — renters’ workspaces).

Within a minute the machine appears in the dashboard with its GPUs. When all GPUs are supported it becomes active and starts receiving renters.

Levels and earnings

Section titled “Levels and earnings”

You earn a share of the rental price for every second a renter’s server runs on your machine:

Level Share Requirement
Bronze 65% start level
Silver 75% 95% uptime, machines active for 7+ days
Gold 85% 99% uptime, machines active for 30+ days

Uptime is the share of time your machines are online. The level is recalculated automatically; a server keeps the share that applied when it was launched. Higher-level and more reliable machines are offered to renters first.

Example: one RTX 4090 ($0.40/h) rented 16 hours a day earns about $125/month at Bronze and $163/month at Gold.

Payouts

Section titled “Payouts”
  • Earnings are on hold for 7 days (to cover disputes), then become available.
  • Payouts are made in USDT on TRON (TRC20). Set your address in Rent out your GPU → Payouts.
  • Minimum payout: $10. Request any available amount; the team sends it and the transaction hash appears in the payout history.
  • After changing the payout address, payouts are paused for 48 hours (protection against account takeover).

Managing the machine

Section titled “Managing the machine”
  • Stop renting temporarily: sudo systemctl stop gysga-agent. The machine goes offline; running renters are paused (not charged) and your reliability drops, so avoid stopping while servers run.
  • Remove a machine in the dashboard. It’s only possible when no renters’ servers are left on it; the agent’s credentials are revoked.
  • Uninstall:
    Terminal window
    sudo systemctl disable --now gysga-agent
    sudo docker rm -f $(sudo docker ps -aq --filter label=gysga.instance) 2>/dev/null
    sudo docker network rm gysga
    sudo rm -rf /etc/gysga /var/lib/gysga

Troubleshooting

Section titled “Troubleshooting”
Terminal window
journalctl -u gysga-agent -f      # live logs
sudo systemctl restart gysga-agent
nvidia-smi                        # GPUs visible?
docker run --rm --gpus all nvidia/cuda:12.8.1-base-ubuntu24.04 nvidia-smi
Symptom Cause
Machine stays pending A GPU is not supported, or GPUs of different models are installed.
not registered: set GYSGA_INSTALL_TOKEN The token was not passed; create a new command in the dashboard.
Install token is invalid, used or expired Tokens are single-use and valid for 24 h; create a new one.
Renters’ servers stay in pulling Slow download or low disk space; check df -h /var/lib/gysga.

Security

Section titled “Security”
  • No inbound ports. The agent only makes outgoing HTTPS connections to agent.gysga.com.
  • Containers are unprivileged: no --privileged, dropped capabilities (NET_RAW, MKNOD, AUDIT_WRITE, SYS_CHROOT), no-new-privileges, limits on CPU, memory (no swap) and processes.
  • No access to your network: the firewall chains block private ranges (10/8, 172.16/12, 192.168/16, 100.64/10), link-local and multicast addresses, the host itself and SMTP.
  • Renters’ data is deleted from your disk when they destroy their server.

Keep the machine updated and don’t run other important services on it. Renters run arbitrary code in containers; container isolation is strong but not a virtual machine.
