See how it works
Select each stage to inspect the mechanism. These are conceptual models, not live networks.
Follow a Bitcoin transaction
Wallet
Select available UTXOs, recipient, change and a fee. This simulation never connects to a wallet.
Inside a Layer 2 rollup
Transaction
The user signs on the selected Layer 2, which has its own chain identifier.
From a market price to a contract
Sources
Observations originate from selected markets and data providers. Market quality affects input quality.
The lifecycle of an Aave loan
Supply
Supply supported collateral to the selected market. Contract and asset risks begin here.
What a wallet signature authorises
Inspect
Check network, recipient, asset and permissions before signing.
A Merkle tree, from data to root
Change leaf A. Watch its fingerprint, its parent and the root change; the B, C and D branches keep their inputs. SHA-256 is calculated locally. This simplified UTF-8 example is not Bitcoin serialization.
