LayerZero has an absolute commitment to continuously evaluating and improving security, to demonstrate this we are pleased to run the largest live bug bounty program across the industry at up to $15M!
You can read more about the program and make reports via Immunefi.
To date LayerZero has awarded almost $1M to white hats that have made disclosures.
A separate bug bounty of up to $2M exists specifically covering The Aptos Bridge, which will in time increase in scope to join the above program. More details on this separate bounty program can be found here.
