Allows to easily create tx to be signed through CLI and submitted on a Safe
Safer is a tool that helps you sign & submit transactions to a Safe, without requiring any interaction with Safe's backend or frontend.
Safer is a set of Foundry scripts that can be used as fallback in case Safe App is down and the blockchain is the only thing that can be trusted.
Safer enables submitting complex transactions without the need of intermediaries.
Safer unlocks true DAO resilience.
make
to initialize the repository..env
file from the template .env.example
file.
SENDER
to the address used to execute the transaction on the Safe. If you don't execute the tx, you don't need to set it.SAFE_NONCE
to override a transaction's nonce. Remove it to use the default, latest Safe nonce. Leave it blank to use nonce 0.FOUNDRY_ETH_RPC_URL
to customize the RPC endpoint used. This is useful to interact with a Safe deployed on another chain than Ethereum mainnet (the default one).make tx
and follow the steps to create a Safe transaction using create-safe-tx; ORdata/tx.json
make sign:ledger
data/signatures.txt
with the signer who will execute the transaction on the Safethreshold
signatures are available in data/signatures.txt
, each one per linemake exec:ledger
With make sign
& make exec
, one can also use any other wallet provider available with cast
:
make cmd:interactive
to input the private key to the command promptmake cmd:ledger
to use a Ledgermake cmd:trezor
to use a Trezormake cmd:keystore
to use a keystoremake cmd:"private-key 0x..."
if you really want to save your private key to your shell's history...You can also append any cast
parameter:
make sign:"ledger --mnemonic 1 --mnemonic-index 1"
or make exec:"ledger --mnemonics foo --mnemonic-indexes 1"
to use another account than the default one at index 0
