Base is part of the **Superchain**, a growing network of Layer 2s that share the same technology stack. This allows apps and tokens to move more easily between different chains, while benefiting from the security of Ethereum. πŸ”— Learn more: [Base](https://base.org) | [Superchain](https://superchain.eco) *** ### Wallets with Account Abstraction Investors can connect an existing Web3 wallet or simply **create a new wallet with their email**.\ Thanks to **account abstraction**, users don’t need to manage seed phrases or external tools, while keeping tokens fully under their control. πŸ”— Learn more: [Account Abstraction](https://thirdweb.com/learn/guides/account-abstraction-the-developers-guide?utm_source=chatgpt.com) *** ### Self-Custody BoulderTech does not custody client assets.\ All tokens are held directly in the investor’s wallet, ensuring **ownership always stays with the user**. πŸ”— Learn more: [What is Self-Custody?](https://www.coinbase.com/learn/crypto-basics/what-is-self-custody) *** ### Security with Battle-Tested Contracts Tokens issued by BoulderTech are based on **battle-tested smart contracts from OpenZeppelin**, the most widely used and audited standard in the Ethereum ecosystem. This ensures reliability and trust from day one. πŸ”— Learn more: [OpenZeppelin Contracts](https://docs.openzeppelin.com/contracts) *** ### Scalability Base allows BoulderTech to handle a **large volume of transactions efficiently**, keeping costs predictable and low for investors. πŸ”— Learn more: [Why Layer 2s Scale Ethereum](https://ethereum.org/en/layer-2/) *** ### Interoperability Tokens issued on Base are **EVM-compatible**, meaning they can integrate with the broader Ethereum ecosystem of tools and infrastructure. πŸ”— Learn more: [Ethereum Virtual Machine (EVM)](https://ethereum.org/en/developers/docs/evm/)
