TRON and Ethereum Take Different Paths to Multisig
Both chains support requiring multiple signatures for a transaction, but they get there through fundamentally different mechanisms — which changes what you need to check for security.
TRON's approach: built into the account
On TRON, multisig is a native property of any regular account — configured directly through the Owner/Active permission structure via AccountPermissionUpdate. No separate contract deployment is needed; the account you already have can be reconfigured in place.
Ethereum's approach: a separate smart contract
On Ethereum, multisig typically means deploying a dedicated smart contract wallet — like a Safe (formerly Gnosis Safe) — which holds funds and enforces its own multi-signature rules in code. Your regular externally-owned account isn't multisig itself; it's just one of the signers authorized to approve transactions through that separate contract.
What this means for checking security
On Ethereum, you'd audit the smart contract wallet's configured signers. On TRON, you check the account's own Owner and Active permission fields directly — there's no separate contract address to look up, which is also exactly why TRON's native multisig can be quietly reconfigured by anyone who briefly holds Owner access, without deploying anything new.
