The problem PolyLiquid solves

What problem does PolyLiquid solve?

Liquid staking is powerful, but today it’s messy, risky, and labour-intensive:

  1. Fragmented tokens & diverging prices – Leading LSTs (stETH, rETH, sAVAX) often trade at different premia or discounts, forcing users to juggle multiple assets and dashboards.
  2. Dangerous, complex cross-chain hops – Traditional bridges remain the #1 attack vector in Web3, and bridging requires a tedious wrap → bridge → unwrap flow.
  3. Manual yield chasing – Staking APRs shift constantly; harvesting and re-compounding by hand wastes gas and leaves yield on the table.
  4. Opaque reserve backing – Users can’t easily verify that liquid-staking derivatives are fully collateralised.

What users can do with PolyLiquid

  • Deposit once, earn everywhere – Hold one PLY token and let the protocol hunt the best staking yields across Ethereum, Avalanche, Base and more.
  • Forget manual upkeep – Compounding, migrations, and hedges all run automatically.
  • Travel safely – Move PLY cross-chain without touching risky third-party bridges.
  • Verify backing on-chain – Anyone can check that every vault share is 100 % collateralised.
  • Join the fun – Predict weekly APR outcomes or enter the no-loss lottery without risking principal.

PolyLiquid turns fragmented, hands-on liquid staking into a single, portable, self-optimising asset—making DeFi yield safer, simpler, and more engaging.

Challenges I ran into

Challenges & quick fixes

  • CCIP decimals bug
    Issue: PLY (18 dec) mis-scaled when minted on Fuji (8 dec test token).
    Fix: Added a shim router that normalises decimals before mint.

  • Functions timeout
    Issue: Polymarket API sometimes exceeded 20 s limit.
    Fix: Cached last good result and used exponential back-off.

  • Gas spikes on rebalance
    Issue: Harvest + swap + CCIP in one tx hit block gas cap.
    Fix: Split into two upkeeps and packed calldata, saving ~40 % gas.

  • UI chain desync
    Issue: Wallet network change mid-tx showed stale balances.
    Fix: Network guard blocks actions until chain IDs match and prompts user.
