In Cetra V2, all user positions are represented physically as ERC-20 compliant tokens on the Push Chain.
π aTokens (Deposit Tokens)
When you supply an asset (e.g., WETH) to Cetra, you receive an equivalent amount of aTokens (e.g., aWETH).
Yield Bearing: aTokens are strictly pegged 1:1 to the underlying asset. When you look at your wallet balance, you will literally see your aToken balance growing every single second. This algorithmic growth represents the interest earned by supplying to the protocol.
Composability: Because it is an on-chain token, it represents your claim on the supplied liquidity.
π DebtTokens
When you borrow an asset, you receive a DebtToken corresponding to the borrowed asset.
Algorithmic Growth: Similar to aTokens, DebtToken balances continuously accumulate upwards. However, this growth represents the accruing borrow interest you owe to the protocol.
Non-Transferable: Unlike aTokens, DebtTokens cannot be transferred to other addresses. They exist purely as an on-chain accounting metric tied to your specific wallet.
