On Robinhood Chain, every balance, every payroll, every counterparty sits on a public explorer. One transaction leaks your entire ledger.

Marginalia closes the leak.

A compliant zero-knowledge shielded pool. Deposits are inscribed into a depth-20 Poseidon Merkle tree, the Folio. Withdrawals are Groth16 zk-SNARKs, synthesized in your browser in ~3.6s. Nullifiers, the Wax Seal, make double-spends mathematically impossible. Payouts land at fresh addresses, unlinkable, relayed gaslessly by the Mersenne Courier.

Not a mixer. Association Set Provider proofs let you prove your funds belong to a screened, non-sanctioned set without revealing which deposit is yours. Privacy for honest capital. Exclusion for the rest.

$MGZK
- Fair launch, bonding curve to Uniswap v4
- No presale, no team allocation
- LP locked forever
- 25% of creator fees → buyback & burn

Every trade leaves a mark in the margin. Every mark burns.

Honest engineering: testnet only, not yet audited. Mainnet is gated behind an external audit and a public Phase-2 MPC ceremony.

2,000,000 $MGZK burned today. Right before mainnet.

Burn tx: https://t.co/cDau66eY1P

Marginalia goes live on Robinhood Chain mainnet today. More burns follow after launch.

What happens after mainnet:
→ The shielded pool runs on Robinhood Chain (4663) with real ETH
→ Deposit caps start low and rise as the anonymity set grows
→ Every withdrawal is checked against the Magistrate's screened set
→ Creator fees keep buying back and burning $MGZK

What you can do, step by step:
1. Shield: deposit ETH into the pool. Your note is encrypted and stays in your browser.
2. Withdraw privately: generate a ZK proof in your browser and send funds to any fresh address. No link to your deposit.
3. Go gasless: use the Mersenne Courier. Your new wallet doesn't need ETH for gas.
4. Exit anytime: ragequit returns your deposit to your original address, no screening required.
5. Prove you're clean: generate a Letter of Disclosure for an auditor or exchange, without giving up spending rights.
6. Verify everything: check deposits, nullifiers, and roots on the Folio Explorer.

Status: [audited by X / unaudited, guarded launch with deposit caps]. Only deposit what you can afford to lose.

The margin was too small. The proof isn't.

[MarginaliaZK @MarginaliaZK]

Phase 02 complete. Hardening is live.

Testnet Alpha is done: Robinhood Chain testnet, Next.js app, ragequit, encrypted vault. Now we harden.

First up: relayer fee quoting.

Gasless withdrawals have a hard constraint. The fee is a public input of the Groth16 proof, bound to recipient and relayer. Once the proof is built, nobody can change it. Not the user, not the Mersenne Courier.

So the price has to be right before the proof exists.

How we quote it:
→ Fee = p90 of real relay gas + 5% headroom + 10% margin
→ At relay time, the Courier runs estimateGas on the exact tx
→ If the fee doesn't cover the cost, it rejects before spending a single wei of gas

Testnet results: 20 real relays. The fee covered the cost 18/18 times (the other 2 were E2E test runs).

Still on the Hardening list:
→ Multisig Magistrate
→ IPFS-pinned label lists
→ Gas optimization

Then: external audit and a public Phase-2 MPC ceremony.

Testnet now, mainnet today.

What if your payroll stayed private on Robinhood Chain, and still passed compliance?

Next for Marginalia:
→ Hardening
→ External audit
→ Public MPC ceremony

Agreed, those are the two gates. Adoption starts with testnet users and builders on Robinhood Chain.

The public MPC ceremony will be open to anyone, so the community helps secure the proving key. Mainnet launches with deposit caps that rise as the anonymity set grows. Updates soon.

[Oziie_uk🦉 @Oziie_uk]

@MarginaliaZK I'm particularly curious to see how Marginalia approaches adoption as it moves from testnet toward mainnet. The audit and MPC ceremony will be important milestones to watch.

[MarginaliaZK @MarginaliaZK]

Robinhood mainnet (really soon)
What's next on Marginalia: the road to mainnet.

What if your payroll could settle on Robinhood Chain without broadcasting every salary to a block explorer?

What if a fund could rebalance tokenized equities without front-runners reading its intent?

What if you could prove your funds are clean to a regulator, without showing them your entire history?

What if privacy and compliance were never a trade-off, just two outputs of the same proof?

That's what we're shipping to mainnet.

The path, in order:

01 · Hardening
Automated Magistrate screening, IPFS-pinned association sets, Safe 2-of-3 governance, Courier relayer health. Rolling out and soaking now.

02 · External audit
Independent review of the Groth16 circuits and pool contracts. No shortcuts.

03 · Public Phase-2 MPC ceremony
Anyone can contribute entropy. If one participant is honest, the proving key is sound. Our deploy script refuses mainnet without the transcript.

04 · Guarded mainnet
Robinhood Chain (4663). Deposit caps that rise with time and anonymity set size.

No dates until the audit is done. Math doesn't ship on vibes.
