Features

Metrics​

Transeptor bundler can be configured to store metrics using a push(InfluxDB) and pull(Prometheus) metrics system. Grafana is used to visualize all the metrics. Use --metrics flag to enable.

Entity Reputation System​

When staked(i.e., with an entrypoint contract), an entity can also use its own associated storage and senders' associated storage as ETH. The bundler can be pre-configured to blacklist(computing) and whitelist(computing) entities on startup.

Geth ERC-7562 Tracer​

Supports native tracer to enforce ERC-7562: Account Abstraction Validation Scope Rules. accountabstraction/geth-with-erc7562-tracer node.

Entrypoint contract​

Supports Entrypoint contract releases/v0.8.

Legacy Entrypoint support​

⚠️ If you are using an older version of EntryPoint, please refer to the links below. We only provide support for the most recent release of our software. We strongly recommend updating your smart contract to use Entrypoint releases/v0.8. For more information, see our Security Policy.

Legacy Transeptor bundler releases:

EIP-7702 authorizations​

On networks with EIP-7702 enabled, the eth_sendUserOperation method accepts an extra eip7702Auth parameter. Transeptor bundler include all UserOperations that require eip7702Auth in a bundle to the authorizationList and execute the bundle using a transaction type 4.

UserOp lifecycle audit trail​

The bundler provides comprehensive audit trail logging to track UserOperations as they progress through the bundle lifecycle. The audit trail captures detailed logging for each stage: userOpReceived, userOpValidationStarted, userOpValidated, userOpValidationFailed, userOpIncluded, userOpSubmittedOnChain, userOpOnChainReceipt, and userOpRejected. Each stage includes timestamps, status changes, error conditions, enabling operators to monitor, debug, and analyze bundler behavior with full traceability. Sensitive data such as signature, callData, factoryData, and eip7702Auth are redacted as 0x_REDACTED in logs to prevent revealing user operation on-chain intent and protect user privacy.

p2p mempool​

Coming soon.

To run Transeptor bundler with ERC-7562: Account Abstraction Validation Rules, a fully synced geth node node must be running alongside the bundler. Both options require the node to be enabled with debug_traceCall.
