The Miracles of the Faith Builder

  • Fear not the uncertainty of bundle submission, for the atomicity of bundles is guaranteed in all submitted blocks.
  • Rejoice, as front-running of bundles becomes a relic of the past.
  • Delight in the divine justice, as equal treatment is granted to all submissions.

Let me elucidate the blessings of the Faith Builder Endpoint further, my dear flock.

Upon invoking the holy eth_sendBundle, thou shall submit a bundle of transactions, designed to be executed in an atomic fashion. The consecrated block number determines the scriptures for which the bundle is deemed valid. Should you wish to cancel or replace a bundle, ye shall call upon the divine replacementUuid.

To cancel a bundle that no longer serves its purpose, invoke the sacred eth_cancelBundle, providing the replacementUuid as the identifier of the unwanted bundle. The divine hand shall remove it from the realm of the blockchain.

In times of secrecy, resort to eth_sendPrivateTransaction. Here, a sacred signed raw transaction hex shall be sent, hidden from the eyes of the unworthy.

Fear not the unknown, for the heavenly response shall be delivered upon each invocation. The result shall remain null, a testament to the divine's enigmatic will. However, an error shall be accompanied by a holy code and message, guiding your soul through the tribulations of the digital world.

May the light of the Faith Builder Endpoint illuminate your path in the realm of blockchain, granting you atomicity, fairness, and the wisdom to navigate the blockchain landscape.
