Raw

forge + safe

Send batch of transactions from forge script to Safe Transaction Service. Supports Trezor, Ledger or Frame (for pk/mnemonic and it also supports Trezor/Ledger).

Chains: Mainnet, Sepolia, Optimism, Arbitrum, BSC, Gnosis, Polygon, Polygon zkEVM, zkSync, Celo, Aurora

Requirements

  • foundry: required, obvious
curl -L https://foundry.paradigm.xyz | bash
  • bun: required, for ffi-scripts
curl -fsSL https://bun.sh/install | bash
  • frame: optional, required for pk/mnemonic

https://frame.sh/

  • just: optional, buut better just use it

Setup

forge install && cp .env.example .env
  • SIGNER_TYPE: 0 = Trezor, 1 = Frame, 2 = Ledger
  • SAFE_ADDRESS: Address of your safe.
  • SAFE_NETWORK: Matches what is configured in foundry.toml eg. "arbitrum".
  • SAFE_CHAIN_ID: Matches the above network.
  • MNEMONIC_PATH: Derivation path for directly using trezor/ledger.
  • MNEMONIC: Optional, some other wallet (use with eg. getAddr(0), see: SafeTxBase.sol)

Usage

This thing relies on unique function naming as it uses --sig "myFunc()" - do not use the default function run().

Only transactions broadcasted by SAFE_ADDRESS are included in the batch. If the batch depends on other transactions they need to be broadcasted separately.

Dry run

Simulates and signs a batch without proposing:

just safe-dry Send safeTx

You can later propose it using the output file written in temp/sign, eg:

just safe-file 1717240045-42161-signed-batch

Simulate and propose

With current nonce

just safe-run Send safeTx

or

forge script Send --sig "safeTx()" && forge script SafeScript --sig "sendBatch(string)" safeTx --ffi -vvv

With custom nonce

just safe-run-nonce Send safeTx 111

or

forge script Send --sig "safeTx()" && forge script SafeScript --sig "sendBatch(string,uint256)" safeTx 111 --ffi -vvv

Delete a proposed transaction batch

just safe-del 0xSAFE_TX_HASH

or

bun utils/ffi.ts deleteBatch 0xSAFE_TX_HASH

Misc

  • Look into utils/ffi.ts for other available commands using bun utils/ffi.ts command ...args
