Mint Supply - Base Documentation

When fiat lands in reserves, mint matching supply. Minting is gated by MINT_ROLE, and an optional supply cap keeps circulation from exceeding your reserves.

Demo

Mint and cap

Terminal

# Mint 1,000 MUSD (6 decimals) to a holder.
base-cast send $TOKEN_ADDRESS "mint(address,uint256)" $HOLDER 1000000000 \
  --rpc-url $RPC_URL --private-key $MINTER_KEY

# Cap total supply. A mint past the cap reverts with SupplyCapExceeded.
base-cast send $TOKEN_ADDRESS "updateSupplyCap(uint256)" 10000000000000 \
  --rpc-url $RPC_URL --private-key $PRIVATE_KEY

Use mintWithMemo to tag a mint with the reserve deposit it backs. See Reconcile with memos.
