multisig stuff to setup with mew

How to

so there're two wallets , transaction goes after you have both signatures.

for this you need two wallets in mew , then deploy this contract with remix with constructor args like that [addr1 , addr2] , 2 . addr's go with quotes. then
load contract from address (remix will show it) and do stringtosend with receiver address and how much money . addr , 2000000

you'll see a string. copy that what is after string : . better use doubleclick to select because you may select carriage_return symbol otherwise.

then

sign this stuff in both mew wallets (sign message in mew)

copy both signatures (0x stuff that goes after sign.:)
then do spend in remix with addr , how much , [sign1 , sign2]. signatures go in quotes

thats all.

if second wallet owner wanna check what he's offered to sign he should do 'load contract from address' aka AtAddress in remix and do 'stringtosend' himself

Side notes

you can also use etherscan for all other than contract deployment. tx has a lower comission than in remix.
2000000 is 0.000000000002 eth
sign'es go without quotes there in spend
stringtosend is in 'Read' there , where spend is in 'Write'
nifty wallet could be used when do "Connect to metamask"
you'll need new stringtosend after successful spendERC20 or spend

ERC20

erc20stringtosend
tcont_addr , addr ,2000000
tok contract address goes first

spendERC20
addr , tcont_addr ,2000000 ,[sign1 , sign2]
tok contract address goes second
