Safe (Gnosis Safe) Multisig Deployment

In short

Safe deployment is the work of bringing the multisig smart-account wallet to a specific EVM chain: deterministically deploying the audited Safe contract suite, standing up the backend and indexed UI, and keeping it current as Safe ships upstream releases.

A Safe deployment puts Safe, the multisig smart-account wallet formerly known as Gnosis Safe, onto a blockchain, so DAOs, protocols, and treasuries can hold assets behind multi-signature approval instead of a single private key. A Safe multisig only executes a transaction once a defined quorum of owners signs it (for example 2-of-3 or 3-of-5), which is the custody standard institutional capital and on-chain treasuries expect before they commit funds.

Protofire has been a partner of the Safe team since 2017, contributing directly to its core codebase, and is an official Safe Guardian; Protofire-deployed networks secure $2B+ in TVL across 120+ EVM networks, so when we deploy Safe on your chain it comes from the team that has done it more than almost anyone, not from a one-off fork. We deploy the audited Safe contract suite, stand up the full backend and indexed UI, brand it to your network, and keep it current as Safe ships upstream releases roughly twice a month, the result is a production multisig your ecosystem can trust on day one, and that stays trustworthy after launch.

The Safe custody and governance stack Protofire builds and maintains

Each layer ships as a maintained service, from deterministic contracts through live monitoring, not a one-time deployment.

01

Safe Contract Suite

Deterministically deployed audited contracts (GnosisSafe.sol, proxy factory, MultiSend, and supporting libraries) with addresses that match every other Safe in the ecosystem.
02

Off-chain Services

Transaction service, API gateway, configuration service, and event-listener indexer that make the contracts usable as a production wallet on any EVM network.
03

Branded Interface

Network-customized fork of the Safe UI with MetaMask and WalletConnect connectors, your domain, and 200+ DeFi app integrations wired in.
04

Modules and Guards

Spending-limit modules, recurring payments, allow-lists, and transfer restrictions that extend or constrain the multisig beyond the base owner-approval flow.
05

Policy and Governance

Safe Guardian oversight that tracks and applies upstream contract, backend, and frontend releases (roughly twice a month) to prevent ecosystem drift.
06

Monitoring and Incident Response

Infrastructure monitoring across staging and production environments, with direct Safe core team access via official Guardian status for rapid escalation.

What we deliver

Safe (formerly Gnosis Safe) is the most widely used multisig smart-account wallet on Ethereum and EVM networks. A Safe deployment is the work of bringing that wallet to a specific chain: deterministically deploying the audited Safe smart-contract suite, GnosisSafe.sol, the proxy and proxy factory, MultiSend, and the supporting libraries, then running the off-chain services a usable wallet needs.

Those services are a transaction service, an API gateway, a configuration service, and an event listener that indexes on-chain activity, plus a branded fork of the Safe interface. Because the contracts are deployed deterministically from the official audited source with no code changes, your Safe addresses and behaviour match every other Safe in the ecosystem, which is exactly what lets DeFi protocols, DAOs, and institutional signers treat it as the standard they already know. It is account abstraction in production: a smart-contract account, not an externally owned key.

An official Safe Guardian since 2017

Protofire is a blockchain engineering company that has shipped 250+ projects across 60+ networks and 95+ protocols since 2016. On Safe specifically, we have been a partner of the Safe team since 2017, contributed directly to its core codebase, and hold official Safe Guardian and Safe Wallet Partner status, which gives us quick PR-review access and close technical collaboration with the Safe core team.

Protofire-deployed networks secure $2B+ in TVL across 120+ EVM networks; we have migrated six networks to the safe.global page and contributed zkSync support, and we maintain a dedicated team focused exclusively on Safe. Networks we have stood Safe up on include Linea, Mantle, Blast, and Optimism, each running a branded, indexed interface backed by 200+ DeFi app integrations.

Beyond Safe, our credentials include maintaining Solhint, the open-source Solidity linter used by 1M+ developers, and running a top-3 indexer in The Graph ecosystem. The proof is at safe.protofire.io, the gateway to every Safe we run.

From request to a live, maintained Safe

When a chain comes to us without a multisig, the request is usually the same: "Every serious DeFi team and DAO asks if Safe is live on our network before they deploy, and it isn't." Our approach starts before any contract is deployed. In a scoping milestone we analyze RPC behaviour and opcode compatibility, because a rollup or app-chain that diverges from mainnet is where deployments quietly break.

We then deploy the audited Safe contract suite deterministically, verify it, and stand up staging and production environments with monitoring, the transaction and gateway services, and a UI forked and branded to the network's domain.

The outcome is a Safe that looks native, like safe.linea.build, multisig.mantle.xyz, blast-safe.io, or safe.optimism.io, backed by indexing and 200+ DeFi app integrations, with MetaMask and WalletConnect wired in. But the deployment is not the finish line. Safe ships frontend, backend, and contract updates roughly twice a month; chains that self-deploy tend to drift into a stale, unmaintained instance within months, which is worse than having no Safe at all because it erodes trust.

As a Guardian with direct line to the Safe core team, we track and apply those upstream releases, add Modules, Guards, and wallet connectors as the ecosystem matures, and can transfer full infrastructure ownership when you want it. The deliverable is not a one-time fork, it is a multisig your network can still rely on a year later.

FAQ

What is a Safe (formerly Gnosis Safe)?
Safe, rebranded from Gnosis Safe, is the most widely used multisig smart-account wallet on Ethereum and EVM networks. Instead of relying on one private key, a Safe is a smart contract owned by several signers that executes a transaction only when a required quorum approves it, for example 2-of-3 or 3-of-5. That makes it a leading example of account abstraction in production: a smart-contract account rather than an externally owned key. Under the hood, a Safe is the audited contract suite, GnosisSafe.sol, the proxy and proxy factory, MultiSend, and supporting libraries, deployed deterministically so its addresses and behaviour match every other Safe in the ecosystem. DAOs, DeFi protocols, treasuries, and institutions use it to custody on-chain assets behind multi-signature approval, which is why it has become the custody standard serious capital expects before committing funds.
What's the difference between Safe and a standard multisig?
A standard multisig does one thing: it requires several signatures before a transaction executes. Safe is a full smart-account platform built around that idea. The same audited contracts deploy everywhere, so every Safe interoperates, and you can extend the wallet with Modules (added functionality like spending limits, recurring payments, and automation), Guards (transaction-level policy enforcement such as allow-lists or transfer restrictions), and Safe Apps (dApps that run inside the wallet so users can swap, bridge, and stake without leaving it). The Safe{Core} SDK, including the protocol-kit and api-kit, gives teams programmatic control to create Safes and propose or execute transactions from backends and dApps. Because DeFi protocols and institutional signers have standardized on Safe's contract interface, a branded Safe deployment plugs into 200+ DeFi app integrations and tooling that a generic multisig simply cannot reach.
How do you deploy Safe on a new chain?
We run it as scoped milestones rather than a single drop. First we validate RPC behaviour and EVM-opcode compatibility, because rollups and app-chains that diverge from mainnet are where deployments quietly break. Then we deploy and verify the audited Safe contract suite deterministically, with no code changes, so your addresses match the rest of the ecosystem. Next we stand up staging and production infrastructure on AWS, the transaction service, API gateway, configuration service, and an event-listener indexer, with monitoring, wire wallet connectors such as MetaMask and WalletConnect, and brand the UI to your domain. Finally we run functional tests, document the setup, and can hand over infrastructure ownership. A first network typically takes one to three weeks; once your infrastructure exists, each additional network is roughly 70% faster. We have done this for Linea, Mantle, Blast, Optimism, and many others.
We're a chain or foundation, why do we need a Safe deployment?
Because Safe is the multisig your prospective builders already expect by name. DeFi protocols, DAOs, and treasury managers routinely ask whether Safe is live on a network before they commit capital, and many simply will not deploy funds without a battle-tested multisig in place. The absence of one quietly costs a chain deals and TVL to ecosystems that already have it. A maintained, branded Safe, one that looks native to your network, like safe.linea.build or safe.optimism.io, signals maturity and interoperability and removes a common blocker to ecosystem growth and developer adoption. It also has to stay current: chains that self-deploy tend to drift into a stale, unmaintained instance within months, which is worse than having no Safe at all because it erodes trust. A live, maintained Safe is table-stakes infrastructure for any EVM chain growing an ecosystem.
What are Safe Modules and Guards?
Modules and Guards are the two ways to extend a deployed Safe, and they work in opposite directions. Safe Modules add functionality that executes outside the normal owner-confirmation flow, spending-limit modules, recurring payments, automation, and self-custodial payment solutions built on audited Safe modules. Safe Guards do the reverse: they enforce extra checks on every transaction before it executes, letting you encode policy such as allow-lists or transfer restrictions directly into the multisig. Together they turn a generic multisig into a customizable smart-account platform where governance rules live in the wallet itself. We add both during the support phase, alongside Safe Apps, dApps that run natively inside the Safe interface so users can swap, bridge, and stake without leaving it, and wallet connectors. For teams that need programmatic control, the Safe{Core} SDK exposes the same capabilities to backends and dApps.
Who maintains the deployment after it goes live?
We do, if you want us to, and maintenance is where most of the long-term value sits. Safe ships frontend, backend, and contract updates roughly twice a month, and chains that self-deploy tend to drift into a stale, unmaintained instance within months, which erodes the very trust the wallet is meant to create. As an official Safe Guardian with a direct line to the Safe core team, we track and apply those upstream releases, monitor the infrastructure, handle incidents, and add Modules, Guards, and wallet connectors as your ecosystem matures. If you would rather run it yourself, you can take a one-time deployment with full infrastructure-ownership transfer and add a support arrangement later if your needs change. Either way, the deliverable is a multisig your network can still rely on a year after launch, not a one-time fork.
