How to Read Multi-Signature Wallet Activity on a Block Explorer

11 October 2026

A multi-signature (multisig) wallet requires multiple private keys to authorize a transaction, rather than just one. On a block explorer, this activity appears as a sequence of on-chain confirmations and executions that correspond to the wallet’s internal approval process. To read it, you look for the transaction that submitted the proposal, the subsequent approval transactions from co-signers, and finally the execution transaction that actually moves funds.

Understanding the Multisig Lifecycle on Chain

Most multisig wallets on Ethereum and compatible chains follow a standard pattern: a proposer creates a transaction, co-signers approve it, and once the required threshold is met, the transaction is executed. On a block explorer, each of these steps is a separate transaction from a different signer address, but they all reference the same multisig contract.

The key is to identify which transaction is the proposal, which are approvals, and which is the execution. The multisig contract itself emits events that the block explorer surfaces in its event log tab.

Step-by-Step: How to Read a Multisig Transaction

1. Find the execution transaction. This is the transaction that actually moved tokens, changed a contract parameter, or interacted with another contract. It will be the most recent in the chain of events. Look for a transaction hash in the activity feed of the multisig wallet address.

2. Open the execution transaction details. Scroll to the "Logs" or "Event Logs" section. The multisig contract will emit an event like ExecutionSuccess or Execution that confirms the transaction was carried out. Note the transactionId (or proposalId) in that event.

3. Search for the proposal event. Use the same transactionId to find the corresponding TransactionCreated or ProposalCreated event. This transaction will show the proposer's address, the recipient, the amount, and the raw data sent. It also records the list of signers and the threshold required.

4. List the approval events. Between the proposal and the execution, there will be one or more TransactionApproved or Confirmation events, each from a different co-signer address. The block explorer will show these as separate transactions. Count them to confirm they meet the threshold.

5. Check the timestamps. The proposal, approvals, and execution must occur in chronological order but can span minutes or days. A gap of more than a few hours between proposal and execution is normal if the wallet uses a timelock.

What to Look For in the Transaction Details

• The to address in the proposal or execution transaction is the contract or wallet the multisig is interacting with. This is the actual destination of the funds or the contract being called.

• The value field shows the native token amount sent. If the multisig is moving ERC-20 tokens, the value will be 0, and the token transfer happens via an internal transaction embedded in the execution.

• The data field contains the function call the multisig is executing. For a simple ETH transfer, this is often 0x. For a DEX trade or a contract interaction, it will be a long hex string you can decode using the block explorer's "Decode Input Data" feature.

Identifying a Multisig Wallet on the Explorer

Most block explorers label common multisig contracts (e.g., Gnosis Safe, Argent, or custom multisigs). If the label shows "MultiSig" or "Safe" next to the address, you can view the "Contracts" tab to see the signers and threshold. This tab typically lists all owner addresses and the current confirmation threshold.

If the explorer does not label the contract, you can verify it by calling the contract's getOwners() and getThreshold() functions through the explorer's "Read Contract" tab. This will return the list of signer addresses and the number required.

Common Pitfalls

• Do not confuse internal transactions with multisig approvals. An internal transaction is a call from one contract to another during a single transaction. Multisig approvals are separate transactions from different wallet addresses.

• A multisig can execute a transaction that itself calls another multisig. In that case, you will see nested events. Focus on the outer multisig's events first.

• Some multisigs use a "queuing" pattern where proposals are submitted but not immediately executable. The block explorer will show the proposal event but no subsequent approvals until the queue is processed.

• If you see many approval events but no execution, the transaction may have been cancelled or revoked. Look for a TransactionCancelled or Revoked event with the same transactionId.

Practical Example Walkthrough

Suppose you see a transaction from a multisig wallet sending 10 ETH to an unknown address. Open that transaction. In the event logs, you find an ExecutionSuccess event with transactionId = 42. Then search for the TransactionCreated event with that same ID. That event shows the proposer was address A, the destination is the unknown address, and the value is 10 ETH. Then find the Confirmation events: one from address B and one from address C. The threshold on the contract is 2, so B and C's approvals were sufficient. Now you know the full story: A proposed sending 10 ETH, B and C approved, and the funds moved.

When to use this information

Reading multisig activity is useful for verifying that a protocol's treasury is being managed as advertised, checking that a token sale wallet isn't making unauthorized moves, or confirming that a DAO proposal was executed correctly. It also helps spot suspicious patterns, such as a multisig that suddenly changes its signer list or executes a large transfer right after a proposal with no approvals visible on chain.

The block explorer gives you the raw events. The story of who approved what, when, and why, is what you reconstruct from those events.
