Solver Node Setup

Guide to setting up and running a Solver Node on the Qubetics Chain Abstraction network.

Prerequisites

• wget is essential to download the binary from the release.

Installing wget

On Ubuntu 24:

sudo apt update
sudo apt install wget -y

On macOS Tahoe 26.3: Using Homebrew:

brew install wget

Download the Binary

You can view the release details here: v0.0.1 Release

Use wget to download the binary for your specific operating system:

For Ubuntu 24:

wget https://github.com/Qubetics/solver-network-binary/releases/download/v0.0.1/mpc-node
chmod +x mpc-node

For macOS Tahoe 26.3:

wget https://github.com/Qubetics/solver-network-binary/releases/download/v0.0.1/mpc-node-mac
chmod +x mpc-node-mac

1. Generate Peer ID

Each Solver Node needs a unique Peer ID to identify itself on the network. Generate one using:

On Ubuntu 24:

./mpc-node --generate

On macOS Tahoe 26.3:

./mpc-node-mac --generate

Save the generated Peer ID — you'll need it for the onboarding step.

2. Onboard & Fund the Node

Once your Peer ID is generated, it needs to be onboarded (registered) on the network. Use the onboarding portal to register:

👉 Onboarding Portal

After onboarding, fund your node with the minimum required liquidity:

Asset	Minimum Required
TICS	100000 TICS
BTC	0.065 BTC

These amounts are examples and subject to change. Refer to the latest network parameters for confirmed values.

Both balances must be met before the node connects. If the minimum requirements are not met, the node will be banned from the network for 1 hour.

3. Run the Node

Start your Solver Node:

On Ubuntu 24:

./mpc-node

On macOS Tahoe 26.3:

./mpc-node-mac

If everything is funded and onboarded correctly, your node will join the network and start participating in DKG rounds, threshold signing, and intent resolution.

Rewards

Solver Nodes earn rewards for processing cross-chain transactions. The reward rate depends on whether the node has been validated:

Status	Reward
Unvalidated	75%
Validated	100%

These percentages are examples and subject to change. Refer to the latest network parameters for confirmed values.

New nodes start at 75% rewards. To unlock the full 100%, the node must go through the validation process — this requires consistent uptime, successful participation in DKG rounds, and maintaining the minimum liquidity at all times.
