Pause Transfers - Base Documentation

Pause the TRANSFER feature during an incident without stopping issuance or cancellation. B20 grants pause and unpause through separate roles so you can separate emergency response from recovery authority.

Demo

Pause and resume transfers

Terminal

# PausableFeature.TRANSFER is enum value 0. The function accepts an array.
base-cast send $TOKEN_ADDRESS "pause(uint8[])" "[0]" \
  --rpc-url $RPC_URL --private-key $PAUSER_KEY

# Mint remains available because only TRANSFER is paused.
base-cast send $TOKEN_ADDRESS "mint(address,uint256)" $BOB 25000000 \
  --rpc-url $RPC_URL --private-key $MINTER_KEY

base-cast send $TOKEN_ADDRESS "unpause(uint8[])" "[0]" \
  --rpc-url $RPC_URL --private-key $UNPAUSER_KEY

Pausing transfers does not pause mint, burn, or any future feature added to the enum. Pause each operation class explicitly.
