What is UTXO Bundling?

UTXO Bundling lets you securely reassign the right to spend a group of UTXOs, without ever moving them on-chain. Rather than merging coins, Thunderbolt reassigns control off-chain. Using a cryptographic trick called a key tweak, users can hand over control of coins instantly, without touching the blockchain.
It’s not just batching. It’s not just compression. It’s a delegation system that preserves Bitcoin’s trust model while unlocking speed and scale.
