How Is the Nonce Managed for a Multi-Signature Wallet?
For a multi-signature (multisig) wallet on Ethereum, the nonce is associated with the multisig wallet's smart contract address, not the individual signers' addresses. Each successful transaction executed by the multisig contract increments its single, contract-level nonce.
The individual signers must agree on the transaction details, including the correct sequential nonce, before signing, and the contract ensures only one transaction per nonce is processed.

The Nonce
Variable ⎊ The Nonce is a variable data field included in the header of a Proof-of-Work (PoW) block, serving as the sole element miners are permitted to adjust during the computationally intensive mining process.
Nonce
Function ⎊ A nonce, short for "number only used once," is a crucial component of the block header in Proof-of-Work blockchains.
