TzSafe

TzSafe is a multisig wallet aiming at providing better assurance of security and management of ownership than a traditional single-signed wallet. TzSafe adheres to the TZIP27 standard, which is the way of signing message for account abstraction.

Multi-signature (also multisig) wallet allows to share the ownership of an account by a smart contract. Each owner can create a proposal to propose transferring Tez or executing other contracts. Signer provides approval stored on-chain by performing Tezos transaction. Once gathering the minimal approvals, the multisig will perform the proposal.

Requirements

The contract is written in cameligo. Please follow the instructions of installation in LIGO.

The minimal required version can be found by performing make ligo-version.

Usage

Entrypoints of multisig

default

This entrypoint can receive Tez from any source.

create_proposal

Each owner can create proposal through this entrypoint. The entrypoint supports creating a batch of transactions. The batch is atomic and execution by order. If modifing settings are proposed, the modified setting will NOT apply in this batch immediately. The setting will effect on a next batch/transaction. Once a proposal is created, its ID can be located in the corresponding emitted event and can be used for both the signing and resolution of the created proposal.

sign_proposal

Signers can provide an approval or a disapproval through this entrypoint.

resolve_proposal

Through this entrypoint, owners have the capability to resolve a proposal. Whether the proposal is executed, rejected, or expires, the allocated storage space will consequently be freed.

proof_of_event_challenge

If TzSafe requires signing message, the contract owner can process the proof-of-event challenge by initiating a proof-of-event proposal through this entrypoint. This proposal, once created, necessitates signing and resolution as the other regular proposals. Following the resolution of the proposal, an event with tag "%proof_of_event" will be emitted, serving as the equivalent of the signature.

Deploy

We provide several steps for quick deploying contracts in app/ to ghostnet.

1. build contracts by performing make build
2. run make get-tezos-binary to get tezos-client binary
3. run make gen-wallet to generate an implicit account. The account information will show up.
4. go faucet to request some XTZ.
5. run make deploy to deploy contracts
