HighCentralization Risk in `Escrow.sol`Acknowledged

In the contract `Escrow` the role `areTrustedHandlers` has authority over the functions shown in the diagram below. Any compromise to a trusted handler account may allow the hacker to take advantage of this authority and for example: set all the addresses he/she wants as a trusted handler, because of the logic of the contract these privileges are not revocable; then a lot of addresses will have the power to call functions that should be protected, this could sabotage the contract. ![](https://accelerator-tasks-prod.acc.corp.certik.com/9278600ca90a4e0990f8811d9be9e4ac/diagrams/centralization-Escrow-areTrustedHandlers.svg)

HighCentralized Control of Contract UpgradeAcknowledged

`EscrowFactory` is an upgradeable contract, the owner can upgrade the contract without the community's commitment. If an attacker compromises the account, he can change the implementation of the contract and drain tokens from the contract.

HighInitial Token DistributionAcknowledged

All of the `HMToken` tokens are sent to the contract deployer when deploying the contract. This could be a centralization risk as the deployer can distribute `HMToken` tokens without obtaining the consensus of the community.
