Describe your issue here.

Environment

• Deployment type: Docker-compose:
• Elixir & Erlang/OTP versions (elixir -version): latest
• Node JS version (node -v):
• Operating System: ubuntu 22.0.4
• Blockscout Version/branch/commit: master
• Archive node type && version: Geth

@vbaranov Hey! I want to add precompile contract code to blockscout.
I have chain, that implement Cosmos core logic and Geth EVM. (e.x. EVMOS). There is deployed precompile contract to address
0x1559000000000000000000000000000000000001 in Cosmos.
EXTCODESIZE == 0, and this contract hasn't deploy transaction emitted to EVM part.
How can I add contract source code manually ?

If I try to INSERT it to smart_contracts table I receive ERROR: insert or update on table "smart_contracts" violates foreign key constraint "smart_contracts_address_hash_fkey"

But I have address 0x1559000000000000000000000000000000000001 in addresses table

What is the best practice of it ?

I think the best way to do this is to pass path to your genesis/chain spec via CHAIN_SPEC_PATH env
But, if this is not applicable to you by any reason, you need to insert contract bytecode to contract_code column in addresses table

@sl1depengwyn Thanks! Will try in a short time
