Wallet Design Requirements for Plasma Chains
Wallets built for Plasma chains have a lot on their plate. They don’t just handle your usual sending and receiving of funds, they’ve got to keep track of transaction histories, store Merkle proofs, and watch what the operator is up to. If something starts to look sketchy, the wallet should know how to trigger an exit on its own. Some wallets even lean on outside watcher services to make things easier for users, but that adds another layer to the whole setup. On top of this, wallets need to keep an eye on challenge periods and make sure exits happen in the right order. All this extra responsibility makes Plasma wallets way more complicated than your typical Ethereum wallet. Honestly, building and using these wallets comes with more headaches and hurdles than what you’d deal with on rollup-based Layer-2 solutions.
