Start Your Own Kora Relayer

Kora relayers help Livre Wallet users submit private shielded-pool transactions on Solana. Running a relayer helps decentralize the network and can let operators earn configured relayer fees from supported transactions.

One-command install

curl -fsSL https://solprivatewallet.com/install-kora-relayer.sh | sudo bash

The installer creates a relayer key, installs the Kora service, creates a systemd service, and prints your relayer public key.

What a relayer does

• Pays Solana network gas for supported private transactions.
• Submits shielded-pool transactions to Solana.
• Helps users avoid linking their wallet directly to gas payments.
• Can earn configured relayer fees from supported pools.

What a relayer cannot do

• It cannot see or take user seed phrases.
• It does not control user wallets.
• It does not custody user funds.

Mainnet program IDs

Shielded pool program:

Verifier adapter:

After install

Check status:

systemctl status kora-relayer.service --no-pager -l

Watch logs:

journalctl -u kora-relayer.service -f

Edit config:

/etc/kora/kora.env

Public endpoint

For public use, put the relayer behind HTTPS with Nginx or Caddy:

https://your-relayer-domain.example -> localhost:8788

Emergency mode

Livre Wallet can also support emergency local mode. Emergency mode does not require a Kora relayer. The wallet generates proofs locally and submits through Solana RPC with the user paying network gas.

Security

• Use a dedicated hot wallet.
• Keep only operational SOL in the relayer wallet.
• Back up your relayer key securely.
• Restrict SSH access.
• Use HTTPS.
• Never ask users for seed phrases, private keys, PINs, wallet files, or recovery words. A legitimate Kora relayer only receives proof packages and public routing data. Relayer operators cannot recover user funds and do not need custody of user wallets.
