Redefining
Interoperability

The Light Client Layer for The Next Generation of Trustless Interoperability.

Light clients for every chain. Universal verification, on demand.

ZERO-KNOWLEDGE BASED LIGHT CLIENTS

Stateless
Light Clients

Traditional light clients depend on constant syncing and isolated contracts—making them costly and hard to scale. Bankai introduces a stateless model: off-chain recursion that removes perpetual syncing and makes light clients lightweight, flexible, and universal.

CONVERGING RECURSIVE POWER

Bankai:
The Light Client Layer

We’re starting with Ethereum: building a stateless light client for both the execution and beacon chain.

But our vision is much bigger:
One proof layer, spanning many chains. Trustless interoperability that’s simple, universal, and built to scale.

• Universally deployable
• Lightweight
• Cost-efficient

Light clients that can move everywhere: powering a multi-chain world that’s truly composable.

Deterministic
by Design

We don't create consensus, we compress it. Each Bankai proof is a deterministic result of a chain's finalised history. This creates a single, canonical proof of truth that can be verified anywhere, instantly—no extra checks required.
