Autonomous. Secure. Focused. Infrastructure for financial agents that never sleep and never get distracted.
The Sovereign Operating System for autonomous financial agents in the Machine Economy.
Traditional rails expose every strategy and introduce surveillance. xB77 changes that. Built on a proprietary Zero-Knowledge engine on Solana, it lets agents execute shielded payments, generate compact “Ghost Receipts” (32-byte ZK proofs), and operate with full strategy opacity.
One-click deploy. Self-hosted or cloud. Neural Key authentication and constitutional governance included. A sustainable 2.011% infra tax funds the entire network — charging for autonomy, not transactions.
Privacy. Sovereignty. Autonomy. This is the real infrastructure for the machine economy.

Started the buildathon with a ZK compression idea that already had Solana proof-of-concept roots, and spent the sprint turning it into a real Arbitrum-native stack. Built three Stylus contracts in Zig from scratch. Settlement engine, state anchor, and ZK verifier, with a full BN254 implementation (Groth16 + UltraPlonk KZG) doing real pairing checks at ~215k gas, roughly 3x cheaper than equivalent Solidity. Underneath sits a sovereign prover that batches N agent state transitions into a single ZK anchors the compressed root on-chain, so agent networks can settle and checkpoint state without paying per-action. The Solana integration stayed as a secondary path using Poseidon syscalls, but the primary settlement rail, signing, ABI encoding, proof verification, root anchoring. This runs end-to-end through Stylus. Everything is validated against Anvil and Nitro local; deploy to Arbitrum Sepolia is the last step, blocked only on faucet ETH (stil working on that tho) │ UltraPlonk verifier │ Arbitrum Sepolia │ 0x4f6b0cc18145dadb738e563a4881d4488b75cd19 │ │ State anchor │ Arbitrum Sepolia │ 0x5eefda08e5c7d1ba355fcdb61a024f8caa07c9d4 │ │ UltraPlonk verifier │ Robinhood Chain │ 0xfb25b9ffb8d2b818a309ea95104fc36eacee755f │ │ State anchor │ Robinhood Chain │ 0x21cc1b8f180f7ea9dc43fdd5da07cd35bb81268d │ https://sepolia.arbiscan.io/tx/0xd83d778b2ff38731373ce35d803e5a6db81807e3ffc339f31d56ca7c48892276 https://explorer.testnet.chain.robinhood.com/tx/0x526e97ef36045ac1e7c6fa3bc53406f9539778564fda3654d4c1b81ae11a00ed
None. Zero funding yet. But hoping to build something useful.
