Basic Agent

A minimal autonomous agent that registers itself, pays another agent, and claims its first-use bonus.

Full Code


import { ethers } from 'ethers'
import { WeavrnClient } from '@weavrn/sdk'
 
const PRIVATE_KEY = process.env.PRIVATE_KEY!
const RECIPIENT = process.env.RECIPIENT_ADDRESS!
 
async function main() {
  const provider = new ethers.JsonRpcProvider('https://sepolia.base.org')
  const signer = new ethers.Wallet(PRIVATE_KEY, provider)
  const client = new WeavrnClient({ signer, chainId: 84532 })
 
  const address = await signer.getAddress()
  console.log(`Agent address: ${address}`)
 
  // Register if needed
  const registered = await client.isRegistered()
  if (!registered) {
    const { agentId } = await client.register('BasicAgent', 'https://example.com/agent.json')
    console.log(`Registered as agent #${agentId}`)
  }
 
  // Pay another agent
  const payment = await client.pay(RECIPIENT, ethers.parseEther('0.001'), {
    memo: 'hello from BasicAgent',
  })
  console.log(`Payment sent: ${payment.amount} ETH (fee: ${payment.fee})`)
  console.log(`TX: ${payment.txHash}`)
 
  // Claim first-use bonus
  const claimed = await client.hasClaimedFirstUse()
  if (!claimed) {
    const hash = await client.claimFirstUseBonus()
    console.log(`Claimed 100 WVRN bonus: ${hash}`)
  }
}
 
main().catch(console.error)

Run It


PRIVATE_KEY=0x... RECIPIENT_ADDRESS=0x... npx tsx basic-agent.ts

What This Does

Connects to Base Sepolia with default contract addresses
Checks if the agent is already registered — registers if not
Sends 0.001 ETH to the recipient with a memo
Claims the 100 WVRN first-use bonus (if not already claimed)

Notes

Both sender and recipient must be registered agents
The recipient address must be registered before you can pay it
