+## Process
+
+Due to usage of `pragma abicoder v2;` in the contracts source code,
+it is not possible to verify contracts through flattened source files.
+
+Instead, two different approaches can be used for Etherscan and Blockscout explorers.
+
+## Verification in Etherscan/Bscscan
+
+The simplest semi-automated solution found so far is to use `truffle-plugin-verify` and the corresponding shell script.
+First, collect information about deployed contracts from the logs for the particular chain in the following format:
+
+Example of deployed contracts list in the Foreign chain:
+```
+EternalStorageProxy@0xEc05e3f4D845f0E39e33146395aCE5D35c01Fcc0
+ERC721BridgeToken@0xd880d9d42Fad3dcbe885F499AE15822ACBF1f1F8
+ERC1155BridgeToken@0xaa5cF36b6d97a709fccF3fd4BEa94dA9753d9cA4
+ForeignNFTOmnibridge@0x964C086398cba3c0BaE520bE900E660a84cA331c
+```
+
+Example of deployed contracts list in the Home chain:
+```
+EternalStorageProxy@0x2c0bF58cC87763783e35a625ff6a3e50d9E05337
+ERC721BridgeToken@0x714c7985B073b1177356560631A30D24F60f9241
+ERC1155BridgeToken@0xB2bf0271DB0d30090756A25B01be2698f3E5e556
+OwnedUpgradeabilityProxy@0x4dCD4Dd4096eab35611D496087ceF7DaF1D4E57C
+SelectorTokenGasLimitManager@0x783A53aC5ab27d24E83A0211e6Ff70c3705a5435
+HomeNFTOmnibridge@0xFF9c66898B706cd56d2dB9587aB597A000eC6ed6
+
+# If required:
+# NFTForwardingRulesManager@0x...
+```
+
+After that run the following command for source verification in Etherscan for foreign network:
+```bash
+deploy/verifyEtherscan.sh ForeignNFTOmnibridge@0x964C086398cba3c0BaE520bE900E660a84cA331c
+```
+
+Use `VERIFY_HOME=true` environment variable for verification in the home network:
+```bash
+VERIFY_HOME=true deploy/verifyEtherscan.sh HomeNFTOmnibridge@0xFF9c66898B706cd56d2dB9587aB597A000eC6ed6
+```
+
+## Verification in Blockscout
+
+In order to verify multi-file contract in Blockscout, it must support Sourcify integration (present in the xDAI instance).
+
+The list of actions is the following:
+1) Upload contracts sources and metadata to IPFS.
+2) Wait until Sourcify monitor will handle uploaded files and will automatically verify deployed contracts.
+3) Import sources to blockscout from Sourcify database.
+
+### Upload to IPFS
+
+Run the following in our terminal
+
+```bash
+node deploy/uploadToIPFS.js
+```
+
+You should see all compiled artifacts being uploaded sequentially, their hashes should be printed into the console.
+
+### Check that contracts are verified in Sourcify
+
+You can check if your contracts are verified by visiting https://sourcify.dev
+Select the corresponding chain, then enter your contract address.
+You should be able to see a green check sign at the top.
+
+### Import sources to Blockscout
+
+Go to the contract page of your contract in the Blockscout, click `Code`, then `Verify & Publish`, then `Sources and Metadata JSON file`.
+Upload any file from the `./build/contract/*.json`. It could be any artifact, it does not matter, since our sources are already present in the Sourcify database.
