Deployment

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

2. Run deployment commands:

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

3. To verify on Etherscan using Hardhat, try:

hardhat etherscan-verify --network <network>

4. To verify on Etherscan using solt, run:

source scripts/solt.sh
run_solt_write

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.

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

First, flatten the contract to verify:

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

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