Problem Statement

One-Liner: Supercharge! offers a basic non-custodial wallet interface, essential for a seamless exploration of the growing Superchain ecosystem. (For demo, we integrated Optimism, Zora, and Base.)Background: Wallets play a pivotal role as the primary gateway for users to interact with blockchains and DApps. They define user interactions and data presentation, making them crucial infrastructure for a multichain ecosystem. Thus, we firmly believe that wallets represent fundamental infrastructure for fostering a multichain ecosystem, and Supercharge! lays the groundwork for further development.Key Features: (a) Import EOA (b) At-a-glance view of all balances on OP stack chains + Manage chain list (c) Send tokens + All of your wallet addresses in the Address Book (d) Sign and send arbitrary transactions (e) Support fee calculation of OP stack chains (L1 data fee + L2 execution fee)

Solution

Supercharge! was inspired by and forked from the Keplr browser extension wallet (the open-source wallet for the Cosmos/Interchain ecosystem), particularly from its basic key/tx management logic and cross-chain UI. We used ethers.js to handle Ethereum/EVM-compatible data. The L1 data fee implementation is based on @eth-optimism/fee-estimation.
