When I use the etherchain.org API to get all the transactions in a block, it also returns contract messages. For example for block 911516, this call returns 7 transactions:


However when I use this query in Geth for the same block, it reports only one transaction:


Apparently etherchain.org includes contract-to-contract messages in addition to transactions. Is there a way to obtain these messages in Geth?

This is not possible in general. Internal calls to other contracts are only part of single transaction execution.

However, if a called contract emits logs they are available in transaction receipts.


You can try to look it at Ether.camp project, i looked at it contracts, raw info.


It is possible currently with both Geth and Parity, although with non-standard APIs. See the answers to How to get contract internal transactions.
