Authenticate with Prflght Using Your Solana Wallet

Prflght authenticates you through your Solana wallet. There are no passwords or email-based accounts. You sign a message with your wallet to prove ownership, and the dashboard issues an API key you use to authorize all subsequent SDK calls.

Dashboard authentication

Go to app.prflght.xyz.
Click Connect wallet and select Phantom or Solflare.
Approve the connection in your wallet extension.
Sign the authentication message when prompted. The message is plain text — it does not authorize any transaction or transfer of funds.

Once you sign, the dashboard opens and your session is active. Sessions persist until you disconnect your wallet or revoke access from the dashboard.

API key

Your API key is generated automatically when you first authenticate. Find it in the API Keys section of the dashboard. Use the API key alongside your agent’s wallet public key when you initialize the Firewall client:

import { Firewall } from '@prflght/sdk'

const firewall = new Firewall({
  apiUrl: 'https://api.prflght.xyz',
  agentId: agentKeypair.publicKey.toString(), // base58 public key of your agent's wallet
})

The agentId field must match the agent wallet you registered in the policy editor. Prflght uses this value to look up the correct policy and to verify that requests are coming from the expected agent.

Environment variables

Store your credentials in environment variables rather than hardcoding them:

PRFLGHT_API_URL=https://api.prflght.xyz
PRFLGHT_AGENT_ID=<agent wallet pubkey>

Then reference them in your SDK config:

const firewall = new Firewall({
  apiUrl: process.env.PRFLGHT_API_URL,
  agentId: process.env.PRFLGHT_AGENT_ID,
})

Never commit your API key to source control. Store it in a secrets manager, a .env file excluded from version control, or your deployment platform’s secret storage. Anyone with your API key can submit firewall check requests on behalf of your agent.

Authentication errors

If the agentId in your SDK config does not match the wallet you registered, or if your API key is invalid or revoked, Prflght blocks the transaction and throws a FirewallDenyError with a descriptive reason. Check the err.reason field to distinguish an authentication failure from a policy violation:

import { FirewallDenyError } from '@prflght/sdk'

try {
  const result = await firewall.check(txBase64)
} catch (err) {
  if (err instanceof FirewallDenyError) {
    console.error('Blocked:', err.reason)
    // e.g. "invalid API key" or "agentId mismatch"
  }
}

To rotate your API key, open the API Keys section of the dashboard, revoke the existing key, and generate a new one. Update your environment variables before restarting your agent.
