Stablecoin

Upgradeable ERC20 token with freeze and gas-less transaction capability.

Contract conforms to EIP-20 , EIP-712 , EIP-2612 and EIP-2771 .

Setup

To install with Foundry :

forge install

Test

forge test

Build

forge build

Deploy

Deploy and verify sample token with Transparent Proxy EIP-1967 :

export RPC=
export PK=
export ETHERSCAN_API_KEY=

forge script script/DeployStablecoin.s.sol:DeployStablecoinScript --rpc-url $RPC_URL --private-key $PK --broadcast --verify --etherscan-api-key $ETHERSCAN_API_KEY -vvvv

Note that some RPCs might have rate limits so concurrent deployments might be rejected. If so, run the script line by line.

Verify

If the contract is deployed without verification or if the deployed chain is not supported by forge, verification could be done independently:

export ETHERSCAN_API_KEY=

forge verify-contract --chain-id 12345 --compiler-version 0.8.14+commit.80d49f37 0x1234 src/Stablecoin.sol:Stablecoin --verifier-url https://api.explorer.com/api

Note that the chain-id and explorer's verifier-url is required.
