Is there a max stack depth in EOSIO?

Question

For ethereum it is 1024, is there one for EOSIO, if so what is it?

Answer 1

for call depth: 250 by default (and all public eosio networks I'm aware of).

for action depth: it is controlled by default_max_inline_action_depth chain configuration parameter. It defaults to 4, but on mainnet it's 10 at the moment. you also have to be aware of the inline actions which exist on EOSIO blockchains. inline actions aren't equivalent to "message calls" (is this the right term on ETH?). message calls are synchronous whereas inline actions on EOSIO occur after (but not necessarily directly after) the currently running action.
