root-agent-sdk

Pay. Verify. Create your agent. Access the onchain economy.

The missing SDK between real humans and the Celo agentic economy.

What it does

root-agent-sdk gives any Celo project 3 core functions to onboard verified humans and create AI agents with economic agency:

• createUser() — Auto wallet + fiat ramp (WaaP + Transak)
• verifyUser() — Human verification with Self Agent ID (ZK credentials)
• createAgent() — ERC-8004 agent wallet with inherited ZK credentials

Plus optional:

• createEscrow() — Conditional payments with configurable split fees (PsyEscrow)

Install

npm install root-agent-sdk

Quick Start

import { RootAgent } from 'root-agent-sdk'

const root = new RootAgent({
  celoNetwork: 'mainnet',
  transakApiKey: 'your-key',
  selfConfig: { appId: 'your-app', scope: ['humanity'] }
})

// 1. Onboard a real human
const user = await root.createUser({ method: 'email', email: 'user@example.com' })

// 2. Fund their wallet (returns Transak URL)
const fundUrl = await user.fundWallet()

// 3. Verify their identity (ZK, no data exposed)
const verified = await root.verifyUser({
  user,
  method: 'self',
  scope: ['humanity', 'sanctions']
})

// 4. Create their agent with inherited credentials
const agent = await root.createAgent({
  owner: user.wallet,
  name: 'myAgent',
  selfCredentials: verified.zkCredentials,
  permissions: ['transfer', 'escrow']
})

// Agent can now transact on Celo with verifiable human identity
await agent.execute({ to: '0x...', value: '1000000' })

How PsyChat Uses root-agent-sdk

PsyChat is a mental health platform where psychologists offer therapy sessions to patients on Celo. The root-agent-sdk powers the full flow:

1. Patient onboarding — createUser() gives each patient a Celo wallet and lets them buy cUSD via Transak
2. Identity verification — verifyUser() confirms the patient is a real human via Self Protocol (ZK proof of humanity), without exposing personal data
3. Payment agent — createAgent() creates an AI agent that manages session payments. The agent inherits the patient's ZK credentials, proving it acts on behalf of a verified human
4. Session escrow — createEscrow() deploys a PsyEscrow contract that holds cUSD until the session completes:
   • Patient deposits before the session
   • If they cancel 48h+ in advance → full refund
   • After session completes → 85% to psychologist, 10% to platform, 5% gas reserve
   • No-show after 1h grace → same split (anti-dropout)
   • Emergency timeout at 7 days → auto-release

const escrow = await root.createEscrow({
  agent: agent.wallet,
  splits: {
    provider: { address: psychologist.wallet, share: 8500 },
    platform: { address: '0xPlatform...', share: 1000 },
    gasReserve: { share: 500 }
  },
  cancelWindow: 48 * 3600,
  timeout: 7 * 86400
})

// Patient deposits for a session
await escrow.instance.deposit('session-001', psychologist.wallet, '25.00', scheduledTime)

// After session completes, agent releases payment
await escrow.instance.release('session-001')

API Reference

new RootAgent(config)

root.createUser(options)

Creates a new user with an auto-generated Celo wallet.

const user = await root.createUser({

  method: 'self',                                // Verification provider

  data: '0x...'         // Optional: raw calldata for contract calls
})
// Returns: { hash, status: 'success' | 'failed', blockNumber }

---

root.createEscrow(config)
