Deployment

• In the project root directory, update .env. Example values are in .env.template.

• Run deployment commands:

hardhat deploy --network <network> --tags <deployment-tags>

• To verify on Etherscan using Hardhat, try:

hardhat etherscan-verify --network <network>

• To verify on Etherscan using solt, run:

source scripts/solt.sh
runsoltwrite()

Then try:

solt verify --license 3 --network <network> solc-input-<contract>.json <deployed address> <contract name>

If the second step fails, go to Etherscan and manually verify using the standard JSON input files.

• (Not recommended, does not work with ABIEncoderV2) To flatten and manually verify on Etherscan:

hardhat flatten <path-to-contract> > flattened.out

Edit flattened.out to remove the duplicate SPDX-License-Identifier lines and submit to Etherscan.
