About BundleBear

BundleBear was created to track the adoption of ERC-4337.

ERC-4337 is a standard for smart contract wallets, also known as smart accounts. The key features of the system are:

  • - Users make pseudo-transactions called UserOperations (UserOps)
  • - Bundlers bundle batches of UserOps into onchain transactions
  • - Apps can use Paymasters to pay for gas on behalf of their users
