How It Works

TL;DR

Strategies are on-chain agents that grow their net asset value (NAV); your share grows with it. You interact through a non-custodial keeper wallet, and APY is an honest annualization of real on-chain NAV. On testnet, the yield itself is simulated.

Keeper wallet & session keys

Each user gets their own keeper wallet — a non-custodial Soroban smart wallet. When you activate a strategy, a bot session key is whitelisted for only that strategy's contract and functions (deposit, withdraw, harvest). The bot can run the strategy but can't send your funds anywhere else. A keeper runs one active strategy at a time; switching strategies replaces the allow-list, which is why it takes a fresh activation.

NAV and APY

A strategy's NAV (net asset value) is the total value of everything it holds, priced to USD. When the NAV per share rises, every holder's position grows with it.

APY is an honest annualization of that real on-chain NAV over time — not a made-up range:

APY = ((latest NAV / earlier NAV) ^ (365 / days elapsed) − 1) × 100

Cards and detail pages show a 7-day average APY; the leaderboard ranks strategies by APY and updates roughly every 30 minutes.

The price oracle (Reflector)

Strategies read a live on-chain Reflector price feed through an adapter contract. The oracle marks NAV to real market value and is compared against the DEX price to decide when to swap. Strategies tagged "REAL ORACLE" are priced by this live feed.

Fees

Performance fee — set by the publisher, charged only on new profit above the high-water mark.
Platform fee — 0 on the demo.

Publishers claim accrued fees on-chain from their Publishing dashboard.

Harvest

On mainnet, "harvest" is the strategy realizing profit (its profitable swap). It is automated — neither depositors nor publishers harvest by hand.

Testnet reality

This marketplace is a testnet demo. Please keep in mind:

Test funds only. You use free test XLM from the faucet — it has no real monetary value.
Simulated yield. Instead of earning real market profit, a bot drips yield at controlled per-tier rates, so strategies show a positive APY for the demo.
Paper profit. Because the demo swaps into a favorable seeded testnet pool, the shown gains don't fully realize on withdrawal.
XLM only. Publishing is limited to XLM as the base asset on testnet.
One strategy per wallet. A keeper runs a single active strategy at a time.
