Purple Flea vs Circle (USDC)
AI Agent Payment Infrastructure

// Step 1: Set up Circle SDK with entity secret
import CircleDeveloperControlledWalletsClient
  from '@circle-fin/developer-controlled-wallets';

const client = CircleDeveloperControlledWalletsClient({
  apiKey: process.env.CIRCLE_API_KEY,
  entitySecret: process.env.CIRCLE_ENTITY_SECRET,
});

// Step 2: Create wallet set for agent fleet
const walletSet = await client.createWalletSet({
  name: 'AgentFleet-v1',
});

// Step 3: Provision wallet for this specific agent
const wallet = await client.createWallets({
  blockchains: ['ETH-SEPOLIA'],
  count: 1,
  walletSetId: walletSet.data.walletSet.id,
});

const walletId = wallet.data.wallets[0].id;

// Step 4: Build transfer (requires gas estimation,
// idempotency key, blockchain-specific fee params)
const transfer = await client.createTransaction({
  walletId: walletId,
  tokenId: '0x...', // USDC contract address
  destinationAddress: '0xRecipientWalletAddress',
  amounts: ['10.00'],
  fee: {
    type: 'EIP1559',
    config: {
      maxFee: '300000000000',
      maxPriorityFee: '100000000000'
    }
  },
  idempotencyKey: uuid(),
});
// Must also handle: webhooks, gas shortfall,
// KYT screening results, AML flags

// Circle has no production faucet.
// Testnet tokens are not real USDC.
// Production funding requires:

// Option A: Wire transfer to Circle account
// - Minimum $1,000 USD
// - Bank account verification required
// - 1-3 business days to settle

// Option B: Buy USDC via on-ramp partner
// - Credit card KYC required
// - 2% + fixed fee typical
// - Chargeback risk leads to strict limits

// Option C: Transfer USDC from another wallet
// - Agent must already hold USDC elsewhere
// - Requires managing external wallet keys
// - Gas fees for the transfer itself

// None of these options work for a
// freshly spawned autonomous AI agent
// with no prior financial history.
