The devnet of XDC supports EIP-1559 now. This article demonstrates how to setup stablecoin on devnet by EIP-1559.
install nvm
Please install nvm first:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash
Then close your current terminal simply, open a new terminal to make nvm take effect.
install node and yarn
The stablecoin-evm project requires node v20.9.0 and yarn v1.22.19:
https://github.com/circlefin/stablecoin-evm/blob/master/package.json#L100-L101:
"engines": {
"node": "20.9.0",
"yarn": "1.22.19"
}
So we install node and yarn with the following commands:
nvm install v20.9.0
nvm use v20.9.0
npm install -g yarn@1.22.19
install stablecoin-evm
Install stablecoin-evm step by step according to the README. But we have to update the Foundry's version in the file setup.sh since nightly-f625d0fa7c51e65b4bf1e8f7931cd1c6e2e285e9 has problem to support EIP-1559.
git clone https://github.com/circlefin/stablecoin-evm
cd stablecoin-evm
# Use nightly-206dab285437bd6889463ab006b6a5fb984079d8 which is latest at 2024-12-16
VER="nightly-206dab285437bd6889463ab006b6a5fb984079d8"
sed -i "s/^FOUNDRY_VERSION=nightly.*/FOUNDRY_VERSION=${VER}/" setup.sh
yarn
yarn compile
yarn hardhat typechain
configure stablecoin-evm
Prepare 1 private key for deploy and 2 addresses for administration:
echo "[]" > blacklist.remote.json
cp .env.example .env
vi .env
Here is my .env file:
DEPLOYER_PRIVATE_KEY="0x1234......"
TOKEN_NAME=USDC
TOKEN_SYMBOL=USDC
TOKEN_CURRENCY=USD
TOKEN_DECIMALS=6
PROXY_ADMIN_ADDRESS="0x85f33E1242d87a875301312BD4EbaEe8876517BA"
OWNER_ADDRESS="0xD4CE02705041F04135f1949Bc835c1Fe0885513c"
MASTER_MINTER_OWNER_ADDRESS="0xD4CE02705041F04135f1949Bc835c1Fe0885513c"
GAS_MULTIPLIER=110
BLACKLIST_FILE_NAME=blacklist.remote.json
Notice:
- PROXY_ADMIN_ADDRESS must be different with OWNER_ADDRESS
- PAUSER_ADDRESS is optional, will be OWNER_ADDRESS if not set
- BLACKLISTER_ADDRESS is optional, will be OWNER_ADDRESS if not set
- LOST_AND_FOUND_ADDRESS is optional, will be OWNER_ADDRESS if not set
deploy on devnet
We can remove the --legacy flag in command line since the devnet supports EIP-1559 now:
forge script -vv --broadcast scripts/deploy/deploy-fiat-token.s.sol --rpc-url https://devnetstats.hashlabs.apothem.network/devnet/
