cosmos 多签/多重签名
- 生成两个普通账户
nscli keys add mykeyname
nscli keys add mykeyname2
- 生成多签账户
lee
,该账户对外转账需要mykeyname
和mykeyname2
的签名
nscli keys add --multisig=mykeyname,mykeyname2 --multisig-threshold=2 lee
- 给多签账户转一点币,便于测试
nscli tx send $(nscli keys show -a alice) $(nscli keys show -a lee) 10bde --chain-id=namechain
- 创建一笔多签交易:多签账户对bob转2bde
nscli tx send $(nscli keys show -a lee) $(nscli keys show -a bob) 2bde --generate-only --chain-id=namechain > unsignedTx.json
unsignedTx.json
