Five sovereigns, live shapes
US and core Europe sit lightly inverted; Japan and Brazil carry the steepness. Pick a country — the curve redraws from onchain feeds.
The keeper walks each curve with a mean-reverting process every 5 minutes. Curves redraw from live onchain feeds — switch a country and watch the shape.
Four moves, one wallet
Any EVM wallet works. Giltyn lives on Robinhood Chain testnet 46630 — the site adds the network for you.
Five sovereign curves, fifteen tenors, all keeper-fed onchain. Pick a country, see where spot sits against the line.
Buy YES/NO shares with USDG — every winning share redeems exactly 1 USDG — or mint the bond itself and hold the exposure.
Resolution reads the feed on the chain. No custodian, no demo data — your book is a public receipt.

Questions, answered plainly
A testnet replica of the sovereign-bond prediction market concept: binary markets on government yields plus tokenized bond exposure, live on Robinhood Chain testnet (46630).
YES/NO shares that pay exactly 1 USDG each if right, or ERC-20 bond tokens whose per-share price is the onchain pool plus coupon accruals.
A keeper simulates each country's curve with a mean-reverting random walk and pushes prices onchain every 5 minutes. Mainnet would switch to real oracles.
Any time for bonds (pro-rata). Markets pay at resolution — anyone can trigger it, and the outcome is read from the feed onchain, not submitted.
A gilt is a UK government bond — and the yields are good enough to convict. Giltyn: guilty of good yield.
No. Testnet experiment with 0 keeper samples so far — not audited, nothing here is a security or an offer.
