+; Contract addresses deployed to Base Sepolia testnet
+; FIXME: currently QA deploy reads these although works against Base (and not Arbitrum)
+;        It should be changed either by
+;           1) setting ETHLANCE_ENV=qa-base during ui & server compilation
+;           2) or change truffle config and when deploying contracts use ETHLANCE_ENV=qa
+;              during contract compilation & deployment
