Biconomy's Bundler API provides a hosted bundler service that enables easy submission of user operations (userops). Bundlers compile these userops into handle operations (handleops) and submit them on-chain via the EntryPoint contract, ensuring smooth transaction confirmations.

Pricing

Our Bundlers are free to use on all chains without any prohibitive subscription pricing. No more need to count API calls you are making, or compute units you consume; send UserOps with full freedom!

Bundlers earn on-chain from pre-verification gas buffer and majorly from the Bundling of multiple UserOps, and we don’t charge you anything on top of this on-chain revenue.
