CCIP v1.6.0 Aptos Events API Reference

Events

This document details the events emitted by the core CCIP modules on Aptos.

onramp

ccip_send

When the ccip_send entry function completes successfully, the onramp module emits a single event, CCIPMessageSent. This event signifies that a new cross-chain message has been initiated and sent from Aptos.

#[event]
struct CCIPMessageSent has store, drop {
    dest_chain_selector: u64,
    sequence_number: u64,
    message: Aptos2AnyRampMessage
}

offramp

execute_single_report

After successfully processing an incoming message from a source chain, the offramp module emits an ExecutionStateChanged event to record the outcome of the message execution on Aptos.

#[event]
struct ExecutionStateChanged has store, drop {
    source_chain_selector: u64,
    sequence_number: u64,
    message_id: vector<u8>,
    message_hash: vector<u8>,
    state: u8
}
