Manual key splitting

anchor keysplit manual \
  --keystore-path /path/to/validator_keystore.json \
  --password-file /path/to/password.txt \
  --owner 0x123abc... \
  --operators 1,2,3,4 \
  --output-path /path/to/output.json \
  --nonce 0 \
  --public-keys key1 key2 key3 key4 \
  --network hoodi

Onchain key splitting

anchor keysplit onchain \
  --keystore-path /path/to/validator_keystore.json \
  --password-file /path/to/password.txt \
  --owner 0x123abc... \
  --operators 1,2,3,4 \
  --output-path /path/to/output.json \
