Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fund-wallet scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Getting an Obolus wallet ready to spend

The wallet cannot fund itself. This is deliberate — Obolus never holds a claim on the user's money and never asks for a card. Your job is to tell the human exactly what to send and where, in the right order, and to know when funding is not the problem.

Call wallet_funding_info first. It returns current_step, next_action and the address, and it is the authority — everything below explains why it says what it says, so you can answer follow-up questions rather than just relaying it.

The three steps are in a forced order

The chain enforces this, not Obolus. Doing them out of order does not fail gracefully.

1 — Send ALGO to the vault address. An Algorand account must hold a minimum balance before it can do anything at all: 0.1 ALGO for the account, plus 0.1 for each asset it holds. So a USDC-capable vault needs 0.2 ALGO, and a little over that is sensible.

2 — Opt the vault into the payment asset. Obolus does this itself; it just needs step 1 done first, because opting in creates the asset holding that the second 0.1 ALGO covers.

3 — Send USDC. Only now.

Why the order cannot be rearranged: an Algorand account cannot receive an asset it has not opted into. The transfer is rejected outright — there is no pending state, no holding area, and nothing to claim later. USDC sent at step 1 does not arrive slowly; it does not arrive.

This matters most when the user funds from an onramp or an exchange, because those deliver USDC and not ALGO. Step 1 still has to happen separately, and the user will not expect that. Say so before they send anything.

What this actually costs

About 0.2 ALGO of minimum balance — cents, not dollars, though re-check the price rather than quoting a figure you were not given. It is not a fee: minimum balance stays in the account and is recoverable when the account is closed.

The buyer pays no transaction fee. The x402 facilitator sponsors it. Settlement transfers land with fee: 0. So the ALGO is for the minimum balance and nothing else — do not tell the user they need ALGO "for gas", because they do not, and it changes how much they think they need to send.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
