Stake USDC, earn pooled yield from Aave, Morpho, and Pendle, and enter weekly prize draws powered by Chainlink VRF — with 100% of your deposit always withdrawable. CLGO holders unlock up to 2x winning odds.
JackCo, a no-loss lottery protocol built on Base, is now live. Unlike traditional lotteries where players risk losing their stake, JackCo lets users deposit USDC that earns yield across established DeFi protocols. That yield is pooled and awarded to weekly winners selected through Chainlink’s verifiable random function (VRF) — while every participant’s principal remains fully protected and withdrawable at any time.
The mechanism is simple. Users stake USDC on Base, where deposits are deployed across diversified, audited protocols — Aave, Morpho, and Pendle — to generate yield. Rather than distributing that yield in small individual amounts, JackCo pools it into a single prize. Each week, winners are drawn on-chain via Chainlink VRF and receive the pooled rewards. The only two outcomes are winning a share of the pool or getting a full deposit back. There is no scenario in which a participant loses their principal. Deposits can be withdrawn at any time, with no lock-up period, starting from as little as 1 USDC.
JackCo introduces a native token, CLGO, that gives holders a measurable edge. Holding CLGO on Ethereum boosts a participant’s winning odds — up to 2x — calculated on a 30-day average to prevent last-minute manipulation. CLGO holders also earn referral rewards across infinite depth: when someone they refer participates, they continue earning CLGO for as long as that user stays active. CLGO is currently listed on MEXC.
Security is central to JackCo’s architecture. Deposits are diversified with a maximum 40% allocation to any single protocol, and an automatic circuit breaker triggers if total value locked drops by 20%. The protocol’s core contracts are immutable, and all prize draws use Chainlink VRF for provably fair, verifiable-on-chain randomness. Deposits on Base are gas-sponsored, meaning users can participate without holding ETH for transaction fees.
JackCo’s launch comes during what the protocol describes as its strongest entry window. With fewer than 1,000 stakers currently participating, individual winning odds are at their highest point. As the community grows, the number of weekly winners scales accordingly — from a handful today to as many as 68 per week at full scale. The earliest participants, designated “Pioneers,” lock in a permanent 1.5x odds multiplier.
JackCo represents a category of DeFi known as prize-linked savings — a model that has historically attracted billions in deposits by removing the downside risk typical of both lotteries and yield farming. By combining principal protection, diversified real yield, provably fair draws, and a token-based odds boost, JackCo aims to make weekly prize opportunities accessible to anyone holding stablecoins.
