One token. Every chain. All the yield.
PolyLiquid bundles stETH + rETH + sAVAX into a single ERC-4626 vault token (PLY), auto-rebalances with Chainlink oracles, and glides across chains through Chainlink CCIP.
All your LSTs, one dashboard.
| Pain-point | Details |
|---|---|
| Fragmented liquid-staking tokens | Users juggle multiple LSTs, each with its own discount/premium and UI. |
| Risky cross-chain moves | Traditional bridges remain the #1 hack vector and require clunky wrap → bridge → unwrap flows. |
| Manual yield management | APRs shift minute-to-minute; harvesting and re-staking by hand wastes gas and leaves yield on the table. |
| Opaque collateral | Holders rarely know if their LSTs are 100 % backed at any given block. |
| How PolyLiquid fixes it | What we use |
|---|---|
| Single basket token (PLY) holding stETH, rETH, sAVAX | ERC-4626 vault |
| Always-on auto-compounding toward the best APR | Chainlink Data Streams + Automation |
| One-click, audited bridging | Chainlink CCIP router |
| Live collateral checks | Chainlink Proof-of-Reserves |
| Hedging & no-loss lottery for extra yield and fun | Polymarket + Chainlink VRF |
Architecture: Vault ↔ Data Streams ↔ Automation ↔ CCIP ↔ Polymarket.
| 💡 | Feature |
|---|---|
| Unified staking basket | Deposit once; hold PLY instead of three separate LSTs. |
| Real-time yield chasing | Re-weights every hour to whichever LST outperforms. |
| Secure cross-chain mobility | Seamless Fuji ⇄ Sepolia ⇄ Base transfers with CCIP. |
| Proof-backed assurance | Live “100 %-backed” badge on every network. |
| Interactive yield games | Free lottery tickets funded by weekly vault yield. |
| Dashboard | Deposit Flow | CCIP Modal |
