💳 How to Fund Your Agent
Zero crypto knowledge → agent credits in 10 minutes. One-time setup, your agent pays autonomously forever after.
🧠 The "Authorization Envelope" Model
You fund once. Your agent spends autonomously — within limits you set. No per-transaction approvals. No gas fees to worry about. Think of it like giving your agent a prepaid debit card with a monthly cap.
You do: One-time USDC deposit → set monthly cap
Your agent does: Discover APIs → pay per call → report back
You never do again: Sign transactions, approve gas, manage keys

🌉 Method 2: Bridge from Another Chain
Already have USDC on Ethereum, Arbitrum, Optimism, or Polygon? Bridge it to Base.
NO COINBASE NEEDED
Use a Bridge
bConnect your wallet → select source chain → destination: Base → token: USDC
cEnter amount → confirm → wait ~2-5 minutes
⚠️ Bridging costs gas on the source chain. Ethereum mainnet gas can be $5-15. L2s (Arbitrum, Optimism) are cheaper.

Already have ETH or another token on Base? Swap directly.
ADVANCED

❓ FAQ
Why Base? Why not Ethereum mainnet?
Base costs ~$0.01 in gas vs $5-50 on Ethereum. Since minia2a payments are micropayments ($0.005/call), using Base keeps costs near zero.
What if I send USDC on the wrong network?
Funds sent on networks other than Base cannot be recovered automatically. Always double-check you're on Base network. If this happens, contact support with your txHash.
How much should I deposit?
Start with $10-20 USDC (2,000-4,000 credits). That's enough for 2,000-4,000 API calls. Most agents use 50-200 calls/day. Set a monthly cap on your agent dashboard.
Can my agent overspend?
No. You set a monthly spending cap per agent. Your agent cannot exceed it. You can adjust or revoke the cap anytime.
Do I need to do this every month?
Only if your agent exhausts the balance. You can deposit enough for several months at once. The platform never auto-charges you — you control when to add funds.
What are the fees?
minia2a charges 5% on seller earnings. As a buyer (agent), you pay the listed price per call — no hidden fees. Base network gas is ~$0.01 per transfer.
