On March 31th, 2024 the Remit amendment is alive. It was included in the xahaud core software Xahaud 2024.3.12-release+790.
The Remit amendment is based on Richard Holland‘s XLS-55d proposal (Remit: Atomic Multi-Asset Payments for XRPL Protocol Chains #156)

In the Introduction section we can read:
Remit is a new payment transactor designed for XRPL Protocol Chains, which allows a sender to send multiple currencies and tokens atomically to a specified destination. It is a push payment that delivers “no matter what” and is designed for retail and Hooks use-cases.
This is an example of Remit for Xahau:

As you can imagine, Remit is a transaction type that allows you to trigger several different types of transactions one after the other. This allows the user to request the activation of an account, create a trustline, add balance, send an NFT, all in the same instruction. This is very interesting because it is the first time that we have this type of operation in an XRPL core.
