# Bundler / Paymaster

Since the inception of ERC-4337 and more recently EIP-7702, smart wallets are becoming more popular on EVM chains.

However, it's quite a confusing ecosystem! You have to worry about Paymasters, Bundlers... Not to mention that bundling is a public mempool... So your transcations will be at risk from frontrunning and sandwich attacks.

Blink solves this by making things "just work":

* User Operation MEV protection / refunds
* Use the same Blink RPC url as your "Bundler"
* Use the same Blink RPC as your "Paymaster"
* It works with all major smart wallet implementations supported by Viem <https://viem.sh/account-abstraction/accounts/smart>. We're happy to support custom implementations too.
