# Create Multisignature address with single keys and make signatures
If you have, for example, 3 single wallets (paper wallets) we can combine for getting a 2/3 multisignature single wallet. So a single address in which funds need 2 signatures (on 3) to be spent. This library allows creating such multisignature single-address wallet and collecting the signatures to spend it.
## Create Multisig and add the first signature
In the following example we create a multisig 2/3, using 3 public keys and use the first private key to make the partial signed transaction transaction.
```
>>> import multisig
>>> from multisig import TestnetMultisig
>>> a=TestnetMultisig(2,3)
>>> a.create_multisig("FIRSTPRIV", ['02ED3F28DA4FF57FE55D97F57E85360A8599093E3C30C37E85A1B9EDF7DC07BE34', '02ECEC779F1EDFAD7F2A37D3EA3FA954FA3DF8FF8F7B42A88F28B035E28E79B0E0', '03638F7C91C2A56A6B2EAC5CF2C545918E447D96973E560CB4E22BAADE136096C4'])

```
## Add the second (or n) signature
Now we can add the signature from the second private key to an already signed transaction with the first key
```
>>> from multisig import TestnetMultisig
>>> a=TestnetMultisig(2,3)
>>> a.create_multisig("SECONDPRIV", ['02ED3F28DA4FF57FE55D97F57E85360A8599093E3C30C37E85A1B9EDF7DC07BE34', '02ECEC779F1EDFAD7F2A37D3EA3FA954FA3DF8FF8F7B42A88F28B035E28E79B0E0', '03638F7C91C2A56A6B2EAC5CF2C545918E447D96973E560CB4E22BAADE136096C4'])
