The wallet is currently funded monthly directly from the dev fund wallet. During a future fork, the funding will be finalized to be part of consensus as agreed upon by the Provisional Council.
Using the Etho Protocol Council Multi-signature Wallet requires 4 of the 7 council members' approval.
All ETHO transactions from the multisig wallet require ECP backing. ECP's are well defined proposals, initiated and voted in the Etho Protocol Council weekly meetings.
Funding ECP's can be passed that fund projects as agreed upon in advance. Such multisig wallet transactions need to reference the Backing ECP within the tracking spreadsheet.
