Connect your own wallet

Paid verification costs $0.10 USDC per check on Algorand. You pay from a wallet you control; Agent Blast Radius never holds, creates or funds wallets, and never sees your keys.

What you need

An Algorand wallet: Pera (phone), Defly (phone) or Lute (browser extension, works with Ledger).
The wallet opted in to USDC (Algorand asset 31566704). In Pera: tap + → search USDC → add.
About 0.3 ALGO kept in the wallet. Algorand requires 0.1 ALGO per account plus 0.1 per asset; it isn't spent. The payment's network fee is covered by the GoPlausible facilitator.
Enough USDC for the checks you want (a few dollars covers many).

Getting USDC on Algorand

Buy in Pera with Pera Onramp, or swap ALGO to USDC inside Pera or Defly.
Withdraw from an exchange (Coinbase, Binance, Kraken…): choose USDC and the Algorand network, and send to your wallet address.
Fiat onboarding can take a while the first time (exchange verification). Do it before you need it.

Paying

In a browser

blast verify prints a link like https://abr.kloudle.dev/pay?code=ABCD-EFGH. Check the code matches your terminal, choose Pera, Defly (scan the QR with your phone) or Lute, and approve. Your terminal picks it up.

From your agent

Give your agent an x402 wallet tool, for example GoPlausible's: in Claude Code /plugin marketplace add GoPlausible/claude-plugins, in Codex codex plugin marketplace add https://github.com/GoPlausible/codex-plugins.git, elsewhere npx @goplausible/algorand-mcp. It creates its own wallet; send it a little USDC and ALGO from yours. The agent pays with the exact arguments blast prints and asks you first.

Good to know

Payments are final. A paid claim stays collectable for 30 days with blast verify --claim <id> or blast verify --list.
Only pay codes you started yourself. The pay page and your terminal always show the same code, amount and pay-to address: 4HBMITKIS36ASVJJFON6X5FOJ4TGDJBJAPOMLEBXGRAXGWWV74WSB7AO7E.
