How It Works
Your Polymarket balance is held in pUSD : Polymarket's native collateral token. When you supply to a DeFi protocol via Shard, pUSD is automatically unwrapped to USDC.e and supplied in a single signature. No manual swaps, no extra steps.
Shard routes your supply directly to the protocol. No intermediary, no custody. Shard adds no fees.
Supply flow one signature, four steps:
Approve pUSD spend
Unwrap pUSD → USDC.e
Approve USDC.e spend on the protocol
Supply USDC.e to the protocol
Everything happens in a single wallet signature.

Lending vs Yield
Lending
Supply USDC.e to a lending pool — earn interest paid by borrowers. Rate varies with utilization.
Auto-compound yield
Deposit into a vault — yield is automatically reinvested to maximize returns.
Note DeFi protocols carry smart contract risk. All protocols listed on Shard have been audited by independent security firms. Shard adds no fees calls go directly to the protocol's audited contracts. Always review each protocol's own documentation before supplying funds.
DeFi Partner Interfaces
Coming soon
Beyond direct protocol supply, Shard is building dedicated DeFi interfaces for ecosystem partners — embedded directly in the app, no external tab required.
Each partner gets its own interface within Shard: supply, manage positions, and withdraw without ever leaving the workspace.
