I'm looking for a simple example of using `L1CrossDomainMessenger` to move tokens/NFTs for a @safe on L1 to the aliased address on the /op-stack. @bountybot 0.125 ETH or equivalent on L2 Success criteria: 1. Safe on L1 with aliased address on L2 2. NFT and/or ERC20 tokens in the aliased address on L2 3. Execute a tx cross-chain via Safe to move the NFT/token to any other address Demo can be on Sepolia and Base/OP Sepolia with a Safe you control. Specifically looking to understand the message required to execute this transfer on the L2 address. Base contracts https://docs.base.org/docs/base-contracts Possibly relevant docs https://docs.optimism.io/connect/resources/glossary#address-aliasing https://docs.optimism.io/builders/app-developers/tutorials/cross-dom-solidity

I dealt with this a few months ago but never actually needed to put it in prod: https://github.com/topocount/sona-protocol/compare/l2-bridge?expand=1

The way to do this "easily" is to use L1/L2 token bridge interfaces (which have canonical examples for interfacing with the XD bridge abstractions). There were a ton of gotchas getting something to actually bridge and it took a lot of trial and error to get it working

Here is the L1 interface https://github.com/topocount/sona-protocol/commit/3b2e98dc959ed982c684e270f947bc8dcf7c4453#diff-64408c03c8ce1c4163dc38b37093407a0d546b9ee5fe537e28a252c87be907b7R172-R192
