ERC-4337: Why Account Abstraction is a Game Changer for Crypto Gambling

ERC-4337: Why Account Abstraction is a Game Changer for Crypto Gambling

Published by Sats Hodler, 3 October 2023

On the first of March 2023 the Ethereum Improvement Proposal (EIP) 4337 was implemented, making the Ethereum Request for Comment (ERC) 4337 standard available to developers. It brings a lot of cool stuff to the table, especially from a decentralized gambling perspective.

So, what is this all about? Mainly it deals with what is called “Account Abstraction”. Without getting into anything technical (for that you can head to , let us start with an overview of some of the good stuff that ERC-4337 makes available.

Account Abstraction and Smart Contract Wallets

This can be seen as an agent controlled by your main Ehereum keys, and can be programmed to do a lot of interesting stuff. For instance they can:

  • Recover accounts without seed phrases – using means like email.
  • Paymaster – allows us to pay gas for others, or have someone else pay for you– it also allows gas to be spent in other ERC-20 tokens, not only ETH!
  • Batched transactions – means less signing, friction in user experience, and reduced gas fees. Approve, and start a new real money game round in one click.
  • Security logic – can be programmed into the wallet, and only allow transfers to whitelisted addresses, basically making it useless even if a malicious actor gains control. Multi sigs can of course also be setup.

With that little overview out of the way, let us look at how it affects crypto gambling with a real-world case that is already live.
