Fletch
Transparent ordering.
Private until execution.
No hidden actors.
The execution layer of Robinhood Chain
Transparent
Ordering is transparent and verifiable. How blocks get built, how transactions are sequenced, how value moves through the system — all auditable after execution. No hidden dynamics. No conflicts of interest.
Private
Transactions remain private until execution via Trusted Execution Environments (TEEs). No front-running. No information leakage. Pre-execution privacy means your intent is protected and ordering happens without exposure.
Efficient
Block building is distributed across a network of high-performance schedulers and validators, optimized for deterministic, low-latency execution. Apps get programmable control over how their transactions are sequenced. Not just faster blocks. Better-structured ones.
Verifiable
Every block built through Fletch produces cryptographically signed attestations that ordering followed the rules. Attribution and accountability are built into the architecture. If a validator misbehaves, the evidence is onchain. Verifiable after execution, not just promised before it.
