Signless Transactions

What are Signless Transactions?

Signless transactions allow users to perform common actions without signing each transaction, offerong a more user-friendly experience, especially for repetitive and routine actions such as trading.
Signless transactions can be activated in your profile on Demex, Carbon's frontend UI.
This guide explains signless transactions and a comprehensive list of actions that can be performed without the need for traditional signature authentication.

Technical Overview of Signless Transactions

The implementation of signless transactions is made possible through two key modules of the Cosmos SDK: authz and feegrant.
  • Authz Module: This module allows a user (the granter) to grant another user (the grantee) the authorization to execute transactions on their behalf. This is facilitated through the MsgGrant transaction, which specifies the types of actions the grantee is allowed to perform. When the grantee executes an authorized transaction, it is done using the MsgExec command, effectively acting under the granter's permissions without needing the granter to sign the transaction.
  • FeeGrant Module: Alongside the authz module, the feegrant module enables the grantee to utilize the granter's account balances to pay for transaction fees. This means that the grantee can perform transactions without needing their own balance for fees, as the granter's balance can be used instead.
