Everyone else in crypto is probably having a good day because prices are up, but gotta say that I’m having a pretty bad one as a crypto consumer developer 🤕

We’ve been working on some internal code to do USDC airdrops. Turns out there’s a different address on each of Ethereum Mainnet, Goerli, Base, and Base Goerli. Oh, and on Base there is a Bridged USDC as well as Native USDC to make things more confusing.

Next, we tried to execute a Uniswap swap in our multisig and somehow external Chrome extensions were messing with some of our browsers. Took about 15 min to do a simple swap without any graceful failures or clear error messages.

Had to figure out how to get a multisig deployed across chains with the same address. People mentioned Deterministic SAFE Deployer, but it turns out figuring out how to run that is non trivial. Smol has a MultiSafe solution, but the SAFE app isn’t autodetecting the new multisig.

Well, we use MPC technology that can have the same address for across chains 🫡
