Technical Overview

The Passage Vault is implemented as a combination of an on-chain smart contract and off-chain logic that lives in Amazon Web Services. The on-chain smart contract is upgradable based on a 3 of 5 multi-signature wallet (i.e Gnosis SAFE). Bracket’s smart contracts have been audited by Halborn.

Some of the computation logic used by the vault is performed off-chain within AWS. The vault’s smart contract logic guarantees that any computations from AWS can only affect creating passage orders for the vault and generating buy offers for traders attempting to sell their active passage trades prior to expiration. The computations from AWS can not request withdrawals or affect any other transaction that could possibly lead to a malicious transfer.
