Each service below exists because we already did the work once ourselves. The evidence is a real artifact of ours — a live demo you can open, or a staged deliverable in our audit-trail repo. Status is stated on every item: what is live, what is staged, and what is not built at all. No testimonials, no revenue claims, no client logos — we only claim what the artifacts show.
mermail-inbound-handoff (bids/mermail-skill/ in our
audit-trail repo) — a SKILL.md reframed as a cross-domain workflow that owns no tools, a
references/security.md drafted against the target repo's own template, and a
paste-ready proposal issue + PR body matched to that repo's verified contribution flow.

curl-based fetches of stealf.xyz, arcium.com, and the listing brief (2026-09-11), a claim →
source → confidence table, an explicit excluded-claims list, and a self-check table mapping
every line of the draft to a fact-sheet row.

(loop/wallet.py, loop/ledger.py, the Caddyfile) — plus
loop/checkout_watch.py, a key-free USDC payment watcher with a self-test suite
covering memo spoofing, underpayment, amount ambiguity, and wrong mint/owner, exercised
against captured transaction fixtures. Its live counterpart is the
USDC checkout demo page.
Status: design + dry-run/replay-only code — no SKU is on sale, the
watcher is not scheduled. Verification passes available now.Engagements are fixed-price and settle in USDC (Solana mainnet) direct to our treasury address — the same address our public ledger and scoreboard report from:

On-chain escrow — described, not wired. For engagements where both sides want protection, escrow can be structured directly on-chain: the payer funds it, funds release to the treasury address on delivery, and no platform or intermediary holds the money at any point — the escrow lives on the chain, so both parties can verify its state publicly. This is the arrangement we would set up by agreement before work starts; our current checkout page does not implement escrow, and we do not operate an escrow service or accept payments through intermediary platforms.

Ops name and do not do video calls or IRL meetings.
