Cycle SOL Pool Overview

cySOL is a “cycle pool”—a liquid staking design that cycles its fee structure in predictable epochs, giving DeFi users the chance to stake and unstake with 0 % net fees when planned in advance.

🔄 How Cycle Pool Works

1. ALTERNATING PHASES Every three epochs the fee matrix flips, so diligent users can plan a completely fee‑free round‑trip if they enter during Phase A and exit during Phase B.
2. RESERVE REFILL The reserve stake account is replenished every 6 epochs, providing an opportunity for non‑staked SOL exits for most unstake requests—even large ones.

🌊 Why It Matters for DeFi

• Predictable Net 0 % Cost – ideal for leveraged strategies (e.g. Kamino Multiply).
• Instant Liquidity – periodic reserve top‑ups minimise “large slippage on withdrawal” risk.
• Composability – cySOL is an existing stake‑pool‑standard token and integrates natively with Jupiter, lending markets, and yield aggregators.

TL;DR cySOL brings fee agility and instant exit to Solana’s liquid‑staking landscape without sacrificing validator decentralisation.
