Stack traces

Stack traces in blocktorch are provided as call trace as well as interaction flow visualization. They are accessible in the log details, the account abstraction explorer and the step debugger.

The stack trace displays the sequence of function calls in a transaction as a tree structure.

Each element represents a function call or event trigger and includes information such as call stack depth, call type, and call parameters.

In the Step debugger you can also access the smart contract source code along with the stack trace to dig deeper into the data.

Call trace

The call trace includes:

• The Calltype which can be CALL, STATICCALL or DELEGATECALL

• The Gas used shown as whole number in [] and on the right side visualized in blue bars to do gas profiling of each function step

• The to address of the contract the call was made to

• The decoded function signature with the argument types it requires

• The + and - signs enable you to elapse and expand the tree

Interaction flow

The call trace includes:

• The Calltype which can be CALL, STATICCALL , DELEGATECALL or OTHER , the call types are also visually color coded as the color of the branch

• The Gas used visualized as the thickness/weight of the branch

• The to address of the contract the call was made to

• The decoded function signature with the argument types it requires

• The round node at each branch can be clicked to elapse and expand the branch
