safe:propose-offline

Create an unsigned Safe transaction, rejection or Safe message without the Safe Transaction Service and bind its JSON to a variable, for owners to sign with safe:confirm-offline.

⚗️ Experimental — available at next.evmcrispr.com.

Smart blocks: cannot be nested. This command performs an immediate wallet, RPC, external-service or control-flow operation and cannot run inside an atomic batch.

Accepts ordinary (...) and smart !(...) payload blocks. Smart blocks support explicit @helper! expressions and returned-value captures.

Syntax

safe:propose-offline <variable> <safe> <proposal>

Arguments

Name	Type	Evaluation	Description
variable	variable	Build time	Variable that receives the unsigned JSON
safe	address	Build time	Safe address
proposal	block | string	Build time	Commands composing the transaction, cancel (with --nonce) to reject a pending one, or a message (text or EIP-712 typed data)

Options

Name	Type	Evaluation	Description
--salt	bytes32	Build time	Smart-batch storage salt for reproducible offline signing (block forms with !)
--nonce	number	Build time	Safe nonce for a command block (defaults to the on-chain nonce), or of the pending transaction to cancel

Creates an unsigned Safe transaction or Safe message, binds its JSON to the variable and prints it, without the Safe Transaction Service. No wallet is needed, so anyone can prepare it, also during simulation. Owners then sign it with safe:confirm-offline.

The Safe commands are named after where their result goes: the Safe Transaction Service (propose, confirm), a variable holding JSON (propose-offline, confirm-offline), or the chain (confirm-onchain, execute). See Offline Safe transactions for the complete flows.

The JSON contains chainId, safe, signatures, version: 1 and kind, plus tx and safeTxHash for a transaction, or message, safeMessageHash and the original content for a message. Numeric transaction fields are decimal strings. Share the complete JSON rather than the block: rebuilding a block later can produce a different transaction if a helper read changed.

Examples

A transaction, at the current on-chain nonce unless --nonce is given:

load safe

set $mySafe 0x5afe3855358e112b5647b952709e6165e1c1eeee
safe:propose-offline $tx $mySafe (
  safe:change-threshold 2
)

A rejection of the transaction pending at a nonce:

load safe

set $mySafe 0x5afe3855358e112b5647b952709e6165e1c1eeee
safe:propose-offline $rejection $mySafe cancel --nonce 42

A message a dapp asks the Safe to sign:

load safe

set $mySafe 0x5afe3855358e112b5647b952709e6165e1c1eeee
safe:propose-offline $msg $mySafe "I agree to the terms"
