Borrow SOL against your bag.

Soloana is a permissionless loan market on Solana. Lock your tokens as collateral and take an instant, risk-priced SOL loan — every loan priced by an on-chain AI risk engine that holds default rates under 2%.

Quickstart

Take your first loan in four steps:

1. Open the app — go to app.soloana.xyz and connect Phantom or Solflare.
2. Get test funds (optional) — use the in-app Faucet to try the flow on devnet first.
3. Post collateral — supply a supported asset (SOL, USDC, JitoSOL, mSOL) as collateral from the Markets tab.
4. Borrow SOL — draw a loan up to your collateral factor, then watch your health factor to stay clear of liquidation.

How Soloana works

Soloana runs a set of permissionless loan markets. Each market is a pool of one asset:

• Suppliers deposit an asset into a pool and earn yield from the interest borrowers pay.
• Borrowers post collateral and take a loan against it, paying a borrow rate that floats with pool utilization.
• The AI risk engine scores each market and borrower, setting a collateral factor and a risk tier so riskier collateral borrows less and pays more.

Interest rate model

Borrow rates follow a two-slope (“kinked”) curve on utilization — cheap while a pool is under-used, steep past its optimal point so liquidity is always available to repay. The SOL market, for example, uses:

// /v1/market/SOL → model
{ base_rate: 0.5, slope1: 6, slope2: 60, optimal_util: 80 }

Supply APY is the borrow interest distributed back to suppliers, scaled by utilization. Live numbers are always in the app and the API.

Borrowing a loan

Borrowing is the core of Soloana. You post collateral, draw SOL, and keep your position open as long as it stays healthy.

How much you can borrow

Each collateral asset has a collateral factor — the share of its value you can borrow against. Higher-quality, AI-scored collateral gets a higher factor:

Collateral factors are set by the risk engine and can change as scores update. Always check the live value in the app before borrowing.

$SOLO-boosted borrow power

Holding $SOLO raises your borrow power: every 100,000 $SOLO unlocks 1 SOL of additional borrow power, up to a 10 SOL cap. The Telegram /borrow command shows your live boost.

Supplying

Loans are funded by suppliers. Deposit an asset into a market and you earn the Supply APY — your share of the interest every borrower in that pool pays. Supplied assets also count as your own collateral, so you can supply and borrow at the same time.

• Non-custodial — you hold your keys, withdraw any time there is free liquidity.
• Yield is real borrow interest, not emissions — it scales with how heavily a pool is used.

Health factor & liquidations

Your health factor (HF) measures how safe your loan is:

HF = (collateral value × liquidation threshold) ÷ borrowed value

• HF > 1 — your loan is safe.
• HF approaching 1 — top up collateral or repay to avoid liquidation.
• HF < 1 — your position can be liquidated to repay the loan.

Use the in-app HF Calculator to model a loan before you open it, and turn on bot alerts with /alerts on to get a DM if your HF drops below your threshold (default 1.2).

AI risk engine

Every market is priced by an on-chain AI risk engine. It scores collateral and borrower behaviour, then sets each market’s default rate, collateral factor and risk tier — with a protocol-wide target of keeping defaults under 2%.

// /v1/risk
{
  default_rate: 0.76, model_version: "v0.4", target: 2,
  markets: [
    { asset: "USDC", score: 95, tier: "A", default_rate: 0.4 },
    { asset: "SOL",  score: 92, tier: "A", default_rate: 0.6 },
    { asset: "JitoSOL", score: 78, tier: "B", default_rate: 1.3 }
  ]
}

Markets & risk tiers

Collateral is grouped into tiers by its risk score. Higher tiers borrow more and price cheaper:

Live markets, APYs and utilization are served from the API and shown in the app.

Faucet

The faucet drips devnet test tokens so you can try the borrow / supply flow risk-free before using real funds. Open the Faucet tab in the app, connect a wallet, and request a drip (rate-limited per wallet).

FAQ

What can I borrow?

SOL, against supported collateral (SOL, USDC, JitoSOL, mSOL today; more as markets are added).

Is it custodial?

No. Soloana is non-custodial — you keep your keys and control your collateral.

Do I get liquidated?

Only if your health factor falls below 1. Keep a buffer, use the HF calculator, and enable bot alerts.

What is $SOLO?

The protocol token. Holding it boosts your borrow power (100k $SOLO = 1 SOL, up to 10 SOL). Not minted yet — boosting runs in demo mode until launch.

Security & disclaimers

Soloana is experimental software. Smart contracts carry risk, including the loss of funds. Borrowing against volatile collateral can lead to liquidation. Nothing in these docs is financial, investment, or legal advice.

• Non-custodial — never share your seed phrase; Soloana will never ask for it.
• Only interact through official links: soloana.xyz, app.soloana.xyz, @soloanapbot, x.com/usesoloana.
• Do your own research and only borrow what you can afford to be liquidated on.
