Burn Supply - Base Documentation

When a holder redeems for fiat, they return the tokens and you burn them, keeping circulating supply matched to reserves. Burning is gated by BURN_ROLE and burns from the caller’s own balance.

Demo

Burn on redemption

Terminal

# Burn 400 MUSD held by your redemption address.
base-cast send $TOKEN_ADDRESS "burn(uint256)" 400000000 \
  --rpc-url $RPC_URL --private-key $REDEMPTION_KEY

Use burnWithMemo to tie the burn to the fiat payout. To reclaim tokens from a blocked account instead, see Recover funds.
