The new signature is only added when the proposal is called again after the proposal verification has passed. Query add-singer proposal account information. ``` $ ppl-sig proposal-info 2DT5HB9DsuK3DhejcmqGvYNAX6tunKa1c cCJH3b28wND Initiator:3AGrFExFviu6Gg6mUgdf4BUbi178Cg43ysbmYc5gbCYv Proposal summary: "3AGrFExFviu6Gg6mUgdf4BUbi178Cg43ysbmYc 5gbCYv initiating add a new signer 9UxRmcoVtr3KMxK3j5WDo9tXE sdYGhwK8Tnqiaw97UBB to multi sig account FF7s3KDy5kSP1wz eZCaj4Ns5boP5cb94k3APvZM2VvHp" ----------------Voted account---------------- 3AGrFExFviu6Gg6mUgdf4BUbi178Cg43ysbmYc5gbCYv ``` You can see in the proposal summary information that indicates which singer initiated the proposal to add singer to which signature account. The voting operation is then performed using other signature accounts at ``` $ ppl-sig vote --proposal 2DT5HB9DsuK3DhejcmqGvYNAX6tunKa1cc CJH3b28wND --signer . /id2.json voting for a proposal 2DT5HB9DsuK3DhejcmqGvYNAX6tunKa1ccCJ H3b28wND Signature: 3ZApa9x22XFmW2vvo8TwDxLZgB2JcHwAzp13DAR4QyakLgb7KkdcXATRQe1jfFjqvKSBT3Yi4qKrfmePNG8ah5sw ``` To view the proposal information again after voting. ``` $ ppl-sig proposal-info 2DT5HB9DsuK3DhejcmqGvYNAX6tunKa1c cCJH3b28wND Initiator:3AGrFExFviu6Gg6mUgdf4BUbi178Cg43ysbmYc5gbCYv Proposal summary: "3AGrFExFviu6Gg6mUgdf4BUbi178Cg43ysbmYc 5gbCYv initiating add a new signer 9UxRmcoVtr3KMxK3j5WDo9tXE sdYGhwK8Tnqiaw97UBB to multi sig account FF7s3KDy5kSP1wz eZCaj4Ns5boP5cb94k3APvZM2VvHp" ----------------Voted account---------------- 3AGrFExFviu6Gg6mUgdf4BUbi178Cg43ysbmYc5gbCYv 4vxfArUy35WeLMwBCe8FEUjWq7gXPpRyF8A85EL44CB8 ``` You can see that the list of voted signatures has changed. The proposal initiator calls the multi-signer interface add-signer again. ``` $ ppl-sig add-signer --msa FF7s3KDy5kSP1wzeZCaj4Ns5boP5cb94k3 APvZM2VvHp -s 9UxRmcoVtr3KMxK3j5WDo9tXEsdYGhwK8Tnqiaw97UBB add new signer in multi sig account FF7s3KDy5kSP1wzeZCaj4Ns5 boP5cb94k3APvZM2VvHp Creating proposal account 2DT5HB9DsuK3DhejcmqGvYNAX6tunKa1ccC JH3b28wND Signature: 5WoF6ohPC9FjDjegztSzv7wT8cwb1hjco1Xey6L1iBt5ZocnCVtUbttBBPDCKpEC7AFghPPPizeaDW8qEMZnZ7uW ``` This operation corresponds to step 9 of the multi-signature process. At this point, the business logic of the multi-signature interface has been executed and the multi-signature account information is queried and you can see that the new singer address has been added. ``` $ ppl-sig multi-info FF7s3KDy5kSP1wzeZCaj4Ns5boP5cb94k3APvZM2Vv Hp Pass Threshold: 49% ----------------all signers---------------- DySd8hi7Z4jrV3ixAk5dT1kPJQzKMiUyyCF38DiJypLY 4vxfArUy35WeLMwBCe8FEUjWq7gXPpRyF8A85EL44CB8 3AGrFExFviu6Gg6mUgdf4BUbi178Cg43ysbmYc5gbCYv 9UxRmcoVtr3KMxK3j5WDo9tXEsdYGhwK8Tnqiaw97UBB ``` Add New Signature Interface is a well-defined multi-signature interface that demonstrates the call execution process for multi-signature contracts and can be referred to when developing custom contracts.
