ERC 4337

ERC-4337 is an Ethereum standard that enables account abstraction, allowing smart contract wallets to offer Web2-like features like social recovery, batched transactions, and paying gas fees with any token. It achieves this without changing the core Ethereum protocol.

Why it matters on AGON

AGON is built for sports bettors, not just crypto natives. The standard crypto onboarding is a high-friction process that kills conversion. ERC-4337 lets us abstract away the complexity. Instead of forcing you to manage a seed phrase for an EOA wallet, we can provision a smart account tied to your social login. No more getting rekt by losing a piece of paper.

This standard powers a seamless betting experience on AGON. You deposit USDC and place bets on /markets without needing ETH in your wallet for gas. Our system uses a Paymaster to handle gas fees, deducting the cost from your USDC balance or sponsoring it entirely. This means one-click betting, not two separate "approve" and "bet" transactions. It's how we deliver a user experience closer to Stake than to a pure DeFi protocol.

How to apply

You don't directly "apply" ERC-4337 as a user; you experience its benefits. The mechanism operates through a separate mempool for UserOperations, which are user intents rather than full transactions.

The flow works like this:

1. You sign a UserOperation (e.g., "place a 100 USDC bet").
2. A network of off-chain actors called Bundlers package your operation into a standard transaction.
3. The Bundler submits this transaction to a global EntryPoint contract on-chain.
4. The EntryPoint contract verifies and executes the operation through your specific smart contract wallet.

A Paymaster contract can be specified in the UserOperation to sponsor the gas fee, enabling payment in USDC or other tokens. This architecture is what makes a smooth, abstracted UX possible on an EVM chain.
