Safe mech delivery decode and related checks
Twenty client-side tools for Safe execTransaction, owners, nonce, modules, guards, token transfers, and event logs. The flagship separates a mech’s outer transaction from the inner call the Safe actually makes.
Safe mech delivery decode
Decode a Safe execTransaction and separate the outer sender from the inner call a mech delivers.
SafeexecTransaction decode
Decode Safe execTransaction calldata: to, value, data length, operation, gas fields, and signature blob length.
SafeSafe multisig summary
Read owners, threshold, nonce, version, and guard from a Safe with eth_call.
SafeSafe nonce gap
Compare the on-chain Safe nonce with the nonce you last saw.
SafeOwner and threshold card
Show the owner list and threshold. Threshold 1 is called out.
SafeSafe module list
Page through enabled modules with getModulesPaginated.
SafeSafe guard status
Read getGuard and show whether a transaction guard is installed.
CalldataTransaction input decoder
Split transaction input into a selector and 32-byte words, marking clean addresses.
Calldata4-byte selector lookup
Match a selector against a local list and, when CORS allows, the public 4byte directory.
CalldataERC-20 transfer decode
Decode transfer, approve, and transferFrom amounts with a decimals scaler.
CalldataERC-721 transfer decode
Decode safeTransferFrom and flag the transferFrom selector shared with ERC-20.
LogsTrace and receipt summary
Summarize a transaction receipt and, if you opt in, a callTracer debug trace.
LogsSafe event log parser
Label receipt logs that match known Safe events such as ExecutionSuccess and AddedOwner.
CalldataMech job id candidate
Show the first 32-byte word of execTransaction inner data as a candidate job id.
CalldataDelivery payload size
Classify inner calldata size as small, typical, large, or very large.
LogsGnosis Chain tx status
Read a transaction and receipt from a Gnosis Chain RPC, or any RPC you paste.
SafeSafe signature count
Count 65-byte chunks in an execTransaction signature blob. This does not recover signers.
SafeapproveHash versus exec
Tell approveHash apart from execTransaction so an approval is not mistaken for execution.
CalldataBatch transaction unroll
Unpack MultiSend transactions into operation, to, value, and data length.
ChecklistSafe transaction checklist
A local checklist to walk before you sign a Safe transaction.
