On-Chain

The chain settles. It does not decide.

Positions settle on RH-CHAIN, chain 4663, an Arbitrum Orbit L2. Everything that requires judgement stays off-chain, where it can be tested and reverted.

Design

Every deployed line is a line you cannot patch.

That single constraint drives the whole on-chain design. Contracts hold custody and settlement — the parts that genuinely need to be trustless — and nothing else.

Strategy, risk limits, and routing live off-chain in Python, where a mistake is a revert and a redeploy rather than a permanent liability. A larger on-chain surface would look more impressive and be considerably worse.

Privacy

Public chains are not anonymous. Plan accordingly.

Masking: Addresses are truncated to 0xabcd…1234 before they leave a process, and no wallet identifier — masked or otherwise — appears in an anonymous response.
Banding: Public balance and deployment figures are rounded into bands. Exact values are operator-only, because an exact figure plus a public ledger is an identity.
Omission: Current holdings and sizes are absent from anonymous responses rather than shifted onto a delayed feed. A live public book would invite front-running.
Registry: Only wallets in the designated registry can be traded against. The registry links a public address to a custody path — never to key material.

On the tension. A site arguing for verifiability that also masks its addresses looks contradictory, and is not. What is verifiable is the behaviourof the system: the caps, the gates, the masking itself. What is withheld is the operator’s position, which is information about a person rather than evidence about a system.
