Predict

Same ADMIN / INITIAL_MINT + salt on every chain → same address (via Foundry’s 0x4e59… CREATE2 factory).

ADMIN=0xYourAdmin INITIAL_MINT=100000000000000000000000000 \
  forge script script/Predict.s.sol

Deploy

cp .env.example .env
# edit .env → set PRIVATE_KEY=0x...  (and ETHERSCAN_API_KEY if verifying)

# optional overrides
# export ADMIN=0xYourAdmin
# export INITIAL_MINT=100000000000000000000000000  # 100M

Same salt + ADMIN / INITIAL_MINT → same CREATE2 address on every chain.
