Multi-signing in the XRP Ledger (XRPL) is a powerful feature that enhances security and flexibility in transaction authorization. This functionality allows multiple secret keys to sign a transaction, providing shared control over an address and serving as a contingency plan in case a key is lost. By implementing multi-signing, XRPL users can ensure that their accounts remain protected even if a single key is compromised. Additionally, this feature can be used alongside other authentication methods, such as master and regular key pairs, ensuring that at least one method remains active at all times. Below, we explore the key benefits of multi-signing, the setup process, and practical applications.
Key Benefits of Multi-Signing
Enhanced Security: One of the primary advantages of multi-signing is its ability to enhance security. By requiring multiple signatures from different keys stored on separate devices, the risk of unauthorized transactions is significantly reduced. Even if a hacker gains access to one key, they cannot execute a transaction without the other required signatures.

Shared Custody: Multi-signing is particularly useful for joint accounts and business operations that require multiple approvals. By distributing signing authority among multiple individuals, organizations can ensure that no single person has absolute control over the account.

Delegation of Control: Multi-signing allows users to delegate transaction authorization to a trusted group of signers. This is beneficial in cases where the primary account holder is unavailable, ensuring that transactions can still be processed without disruption.
Setting Up Multi-Signing: Signer Lists
Before using multi-signing, users must configure a SignerListSet transaction. This transaction establishes a list of authorized signers, each with a specified weight, and defines a quorum—the minimum total weight required to approve a transaction. A SignerList can contain between 1 and 32 entries, excluding the address that sets up the list.
Each signer entry has two key parameters:
- Signer Weight: Determines the level of authority assigned to each signer. A higher weight indicates greater influence over transaction approval.
- Quorum: Specifies the minimum combined weight required to validate a transaction. The quorum must be greater than zero and less than or equal to the total weight of all signers in the list.
Additionally, the Wallet Locator feature in XRPL allows users to embed up to 256 bits of arbitrary data per signer entry. This feature is particularly useful for smart contracts and decentralized applications, as it helps verify signer identities.
Examples of Signer Weight and Quorum in Action
- Simple Shared Account: A quorum of 1 with multiple participants, each having a weight of 1, allows any participant to approve a transaction individually.
- High-Security Account: A quorum of 3 with three signers, each assigned a weight of 1, ensures that all three must approve each transaction.
- Corporate Governance: A quorum of 3 could include a CEO (weight 3), Vice Presidents (weight 2 each), and Directors (weight 1 each). Transactions may be approved by three Directors, a Vice President and a Director, two Vice Presidents, or the CEO alone.
- Emergency Recovery Plan: A signer list with three trusted friends (each with weight 1 and a quorum of 3) can act as an emergency recovery mechanism if the primary key is lost.
Submitting Multi-Signed Transactions
To successfully submit a multi-signed transaction, users must follow these steps:
- Define a SignerList: The sending account must have an active SignerList in place.
- Configure the Transaction: The SigningPubKey field must be empty, and the Signers field must contain the necessary signatures.
- Ensure Signer Compliance: The provided signatures must match those listed in the SignerList, and their combined weight must meet or exceed the quorum.
- Calculate the Transaction Fee: The fee must be at least (N+1) times the standard transaction cost, where N is the number of signatures required.
- Predefine All Fields: All transaction fields must be set before signatures are collected. Auto-filling is not permitted.
- Sort Signers Correctly: In binary form, signers must be arranged in ascending order based on their addresses. The submit_multisigned function automatically handles ordering for JSON submissions.
Conclusion
Multi-signing in the XRP Ledger provides an essential security and governance layer for users who seek enhanced protection, shared control, and delegated authorization. By carefully configuring signer lists, weights, and quorum settings, XRPL users can safeguard their assets while ensuring seamless transaction execution. Whether for personal security, business operations, or emergency recovery, multi-signing offers a robust solution to meet a wide range of needs.
