Thousands of Safe deployments to Optimism were noted by Twitter users, sparking speculation that an attack may have been underway. However, Worldcoin’s developer has clarified that this activity was simply an app migration.
On June 27, Worldcoin developer Tools for Humanity’s head of product, Tiago Sada, disclosed on social media that Worldcoin was the reason for multiple Safe deployments to the Optimism network over the previous week. This information was provided in response to Twitter users’ questions and rumors on the rationale and history of these deployments.

Users who were curious about the deployments’ motivations have conversations about them on Twitter. Some others thought it might be a Sybil attack or a method of address farming designed to make money from coins sent to the erroneous address.
A Safe, formerly known as “Gnosis Safe,” is a multisignature smart contract wallet that development teams frequently use to demand consent from many team members for transactions involving shared funds or software updates. Safes are also used by consumer wallets that permit gas-free transactions, like those that employ account abstraction.
Worldcoin is known for making extensive use of Safes in its operations and only allowing verified individuals to conduct gas-free transactions. The recent announcement by the Worldcoin team to switch from Polygon to Optimism is probably what caused the rise in Safe deployments.
A specific Optimism address, 0x86c5608362b3fbbeb721140472229392f754ef87, opened around 50 subaccounts between June 21st and June 27th, each of which carried out between 10,000 and 15,000 transactions. The majority of these transactions led to the development of brand-new Safe wallets. On-chain researcher Spreek discovered these peculiar transactions on June 26th and informed the community via a thread on Twitter.

Tiago Sada from Tools for Humanity addressed the rumors and clarified the circumstance. Sharing Spreek’s initial message, he added the phrase “Deploying more Safes — steady lads,” confirming that the transactions had been triggered by Worldcoin’s relocation.
Users of optimism should feel relieved by this explanation. It shows that, at least for the time being, the network is not currently under a significant Sybil assault or an address-farming scheme connected to these transactions.

On June 6, optimism received a new version upgrade named “Bedrock.” Since its deployment, the number of transactions has significantly increased thanks to the upgrade’s cheaper costs and quicker deposit times.
