@sept-en this PR doesn't solve issue

Missing function to verify user's whitelisting for the specific token:

as the trader whitelisting functionality doesn't exist in solidity contract :)

[olga24912]

Doesn't work for me:

olga@olga-ThinkPad-P14s-Gen-2a:~/Aurora/spectre-bridge-protocol/eth$ yarn run deploy:verify:bridge -- goerli
yarn run v1.22.19
warning From Yarn 1.0 onwards, scripts don't require "--" for options to be forwarded. In a future version, any explicit "--" will be forwarded as-is to the scripts.
$ npm run compile-all && npx hardhat run scripts/EthErc20FastBridge/deploy_and_verify_bridge.js --network goerli

> project-name@1.0.0 compile-all
> npx hardhat compile --force

For me, this function works 50/50. Sometimes it works, but sometimes returns strange errors. Looks like a race condition.

Do we really need this function? We already have a command to deploy and verify. I am not sure that it is worth to debug it. What do you think?
