Hi! I've been trying all day to have a contract verified, but something is wrong. I used truffle-flattener and the output works fine on remix (I can interact with the contract), but blockscout keeps saying bytecode didn't match. I also enabled the optimizer with 200 runs.
This is the contract https://blockscout.com/poa/xdai/address/0xEEB618686fb36F6B07b44b763B1A5C4267f0c5d7/contracts
And this is the truffle compilation https://github.com/uprtcl/stairwise-token/blob/main/build/contracts/StaircaseBondingCurve.json
The contract has arrays as constructor parameters, beside this, is a rather simple one.
Any advice on how to find what might be the issue here?
Thanks!!
internal_transactions_indexed_at field in the table internal_transactions anymore. Nowadays, status of the internal transactions fetching is checked within pending_block_operations table.

In explorer it's just a problem with opening address of RandomAura. It takes too long and then crashes explorer.
Execution time which I sen is from here:

CHAIN_SPEC_PATH supports only Geth genesis json and Parity chain spec. For instance, genesis JSON file in case of Geth is here https://github.com/poanetwork/blockscout/blob/master/apps/explorer/test/support/fixture/chain_spec/qdai_genesis.json
[Victor Baranov, POA Network] > its possible from explorer to get genesis contracts ?
Only if CHAIN_SPEC_PATH is provided. Thus, only Geth and OpenEthereum are supported by Blockscout for contracts in genesis block.
https://docs.blockscout.com/for-developers/information-and-settings/env-variables
Chain specification path (absolute file system path or URL) to import block emission reward ranges and genesis account balances from. Geth- and OpenEthereum-style specs are supported.
