safe:new

Deploy a new Safe v1.5.0 with the given owners, at a deterministic address that is the same on every chain for the same owners, threshold and salt (created like Safe{Wallet} creates Safes: switched to the L2 singleton on every chain but Ethereum mainnet).

⚗️ Experimental — available at next.evmcrispr.com.

Smart blocks: build-time inputs only. Owners, threshold and salt determine the predicted Safe address.

Syntax

safe:new [...owners]

Arguments

Name	Type	Evaluation	Description
[...owners]	address	Build time	Owner addresses

Options

Name	Type	Evaluation	Description
--threshold	number	Build time	Signature threshold (defaults to 1)
--salt	number	Build time	Deployment salt nonce (defaults to 0)

Examples

Deploy a 2-of-3 Safe:

load safe

safe:new 0x4F2083f5fBede34C2714aFfb3105539775f7FE64 0x44fA8E6f47987339850636F88629646662444217 0x9C58BAcC331c9aa871AFD802DB6379a98e80CEdb --threshold 2

Choose a custom deployment nonce and predict a single-owner Safe:

load safe

set $owner 0x1111111111111111111111111111111111111111
set $salt 42
set $safe @safe:address($owner $salt)
safe:new $owner --salt $salt

The address is deterministic (CREATE2 over the deployment profile, owners, threshold, and salt), and the same configuration gives the same address on every chain with Safe's canonical deployment. Like Safe{Wallet}, the command deploys the plain Safe singleton with a SafeToL2Setup delegatecall in setup(), which switches the Safe to the L2 singleton on every chain but Ethereum mainnet; the deployment inputs are therefore identical everywhere. Use --salt to deploy several Safes with the same configuration. The salt defaults to 0 and is not the Safe's transaction nonce. Repeating a deployed configuration and salt reverts; this command always prepares a deployment.

On chains the canonical Safe contracts never reached (the EEZ devnet), the module uses its own deployment of the same v1.4.1 bytecode through the Arachnid CREATE2 deployer, at the same addresses on every such chain, so a Safe created there has a different address than on a canonical chain. Run scripts/deploy-create2.ts to bring the contracts to another such chain.
