Kairo Review 2026: Swap, Perps and BTC Financing on Arc

Kairo describes itself as the financial layer of the Arc network. From one interface you can swap tokens, trade perps, take part in prediction markets, provide liquidity, lend, join or create on-chain funds, launch tokens and send USDC payments. Every product runs from your own wallet.

The platform also includes a Chrome extension called X Trader, a Bitcoin instalment product called KAIRO Finance, and an optional AI agent built on the Circle Agent Stack. A native token, $KAIRO, is used across the ecosystem, though the project says it confers no equity and no promised value.

The interface is operated by Proodos Group BV. The site is open about its limits: it says it is not licensed or approved by any regulator, and that the X Trader extension and KAIRO Finance are not independently audited. KAIRO Finance deposits and new financing are currently closed.

Kairo is an interface and set of smart contracts on the Arc network. You connect your own wallet, choose a product, and sign each transaction yourself. The project says it never holds funds or keys, so trades settle directly from your wallet.

The swap quotes from live pool pricing and charges a flat 0.25% fee that appears before signing. Perps let you trade with leverage, which means positions can be liquidated if the market moves against you. Prediction markets price outcomes as market-implied probabilities.

KAIRO Finance works like a Bitcoin instalment plan. You pay a deposit of at least 40% in USDC, USDC lenders fund the rest, and the BTC stays locked in a vault. Rules run in smart contracts, with a Chainlink BTC/USD price feed, liquidation at 75% LTV, and liquidation proceeds sold into USDC on Arc. Once every dollar is repaid, the BTC is released.

The swap charges a flat 0.25% KAIRO fee on every chain, displayed before you sign. The X Trader extension adds no extra fee on top of that. Network gas fees from your wallet apply as usual.

KAIRO Finance publishes fixed borrower rates: 9.99% for 6 months, 11.99% for 12, 13.99% for 24 and 14.99% for 36. Late payments add penalties of 2.00% after the due date, 4.00% after 72 hours and 5.00% at 168 hours, when the position is permanently in default. Early payoff carries no fee. Fees for perps, pools and prediction markets are on the project's fees page and are not stated on the homepage.

The project describes itself as non-custodial: you sign every transaction and the extension keeps your recovery phrase encrypted on your device. Even so, every product executes through smart contracts, so bugs, external venues and network issues can cause losses. The project says plainly that the X Trader extension and KAIRO Finance are not independently audited. It does not publish audit reports on its homepage.

Regulatory status is also stated directly: the interface is operated by Proodos Group BV and is not licensed, registered or approved by any regulator. Users are responsible for checking legality in their own jurisdiction, and the site lists geographic restrictions and prohibited markets. Prediction markets are for adults only (18+), and the site links a responsible trading page. Only risk money you can afford to lose.

Kairo is for crypto users already comfortable with self-custody wallets, leverage and early-stage protocols who want to trade or earn on Arc. It is not suited to beginners, to anyone who needs audited or regulated products, or to people who cannot lawfully use such platforms where they live.
