MEV Defense Stack — Curated Namespace Set

Build the MEV Defense
Layer of Ethereum's Future

Fifteen pre-curated, protocol-grade ENS namespaces covering every layer of MEV-resistant infrastructure — from sandwich protection at the user edge, through encrypted mempools and threshold relays, down to the RLN cryptographic primitives that make it all possible. Acquired in the wake of the May 2026 high-profile sandwich attack that put MEV defense back on every roadmap. Every name scored, classified, and resolving on-chain today.

01The MEV Defense Layer CHAIN.MEV · 5 names

The user-facing surface. Where wallets, dapps, and aggregators publish identity for sandwich-resistance, MEV mitigation, and protective routing. "MEV mitigation" is the umbrella term that emerged from the post-mortems; sandwichprotection is the most-named attack with the most-named cure.

mevmitigation.eth
Tier 13 · $5,500/yr
MEV mitigation primitive. The umbrella research namespace for MEV-resistant protocol design — where encrypted mempools, fair-ordering, and threshold-relay solutions converge.
mevshield.eth
Tier 13 · $5,500/yr
MEV shield primitive. Branded protection layer for MEV exposure — where wallet-level shielding, sandwich-resistance, and pre-trade encryption flows anchor on one identity.
antimev.eth
Tier 11 · $3,500/yr
Anti-MEV primitive. The canonical namespace for the anti-MEV movement — where MEV-resistant relays, encrypted mempools, and fair-ordering protocols rally under one banner.
mevdefense.eth
Tier 11 · $3,500/yr
MEV defense primitive. The developer-facing namespace for MEV-resistant infrastructure — where private mempools, encrypted relays, and fair-ordering protocols publish identity.
sandwichprotection.eth
Tier 12 · $4,500/yr
Sandwich protection primitive. User-facing namespace for sandwich-attack resistance — where private order flow, encrypted mempools, and MEV-aware routing protect retail trades.

02Encrypted Mempool Infrastructure SECURITY.MEMPOOL · 3 names

The privacy substrate. Where transactions hide their contents until inclusion — protecting against frontrunning, sandwich attacks, and order-flow extraction. The relay tier is where MEV-Boost-style block-building meets pre-execution privacy.

mempoolrelay.eth
Tier 13 · $5,500/yr
Mempool relay primitive. Canonical relay tier for mempool infrastructure — where encrypted submissions, private order flow, and MEV-aware block builders coordinate.
encryptedrelay.eth
Tier 13 · $5,500/yr
Encrypted relay primitive. Forward-looking relay tier for encrypted-mempool architectures — where pre-execution privacy meets MEV-Boost-style block delivery infrastructure.
mempoolencryption.eth
Tier 12 · $4,500/yr
Mempool encryption primitive. The discipline namespace for hiding pending transaction contents — where threshold cryptography, encrypted relays, and MEV defenses converge.

03User-Facing Encrypted Transactions SECURITY.PRIVACY · 1 name

The end-user namespace. Where wallets, dapps, and protocols anchor end-to-end encrypted transaction flows.

encryptedtransactions.eth
Tier 11 · $3,500/yr
Encrypted transactions primitive. User-facing namespace for end-to-end encrypted transaction flows — where wallets, dapps, and relays anchor private execution standards.

04RLN Cryptographic Backing SECURITY.RLN + SECURITY.ZK · 6 names

The cryptographic primitives that make encrypted mempools possible. Rate Limiting Nullifiers (RLN) are the Vac/Waku research primitive used to enforce rate limits on encrypted message networks without de-anonymizing senders. The foundation under everything above.

rlnindex.eth
Tier 14 · $6,750/yr
Membership index primitive for Rate Limiting Nullifier systems. Tracks group membership for RLN-protected protocols — canonical identity for rate-limited anonymity sets.
rlnregistry.eth
Tier 14 · $6,750/yr
Canonical registry for Rate Limiting Nullifier networks. The reference identity where RLN group membership, rate limits, and nullifier epoch schedules publish.
rlnnullifier.eth
Tier 13 · $5,500/yr
Nullifier primitive for Rate Limiting Nullifier systems. The cryptographic primitive where spent nullifiers prevent double-spending in anonymous rate-limited protocols.
rlnusage.eth
Tier 14 · $6,750/yr
Usage tracking primitive for Rate Limiting Nullifier systems. Monitors rate-limit consumption across RLN-protected protocols to enforce per-epoch message caps.
rlnrouter.eth
Tier 12 · $4,500/yr
Routing primitive for Rate Limiting Nullifier systems. Directs RLN-protected messages through optimal relay networks while enforcing per-epoch rate limits.
nullifierindex.eth
Tier 14 · $6,750/yr
Nullifier tracking primitive for zk protocols. The canonical index where spent nullifiers, anonymity set membership, and double-spend prevention records persist.

How the layers fit together

user tx encrypted relay encrypted mempool block builder L1 inclusion
sandwich shield mev shield (wallet-side defense)
rln nullifier rln registry (cryptographic anti-spam without identity disclosure)
Each name corresponds to a real subsystem in MEV-resistant Ethereum infrastructure. From the user's wallet at the top of the stack down to RLN's group-membership proofs at the bottom — the namespaces a serious MEV-defense team would need to publish.
Full Stack Annual Lease
$78,500/yr
15 protocol-grade namespaces. Available individually or as the full stack when ENSv2 launches subdomain leasing.
No payment now · We'll contact you when ENSv2 ships
Charter Lessee Program · 5 slots site-wide
First 5 production lessees lock their rate for life.

Charter Lessees get a permanent featured rail at the top of the relevant Stack page (not the open-card row — a named "Charter Implementation" position), first refusal on adjacent names in their vertical, and co-launch positioning when ENSv2 ships. Whatever tier price applies at activation never increases. Standard lessees pay the rate at their initiation; Charter rate is permanent.

Hard cap: 5 slots across all 6 Featured Stacks. First-come. After 5, program closes. No payment until ENSv2 leasing activates.

05Why a Curated MEV Defense Stack

The May 7, 2026 sandwich attack wasn't an outlier — it was a demonstration. Every retail trader and every protocol routing flow through public mempools is exposed to extractive bots. The teams building the cure need namespace identity that doesn't sound like a marketing department picked it.

Acquired with intent
9 of these names were acquired May 8, 2026 — the day after the high-profile sandwich incident. Direct response to the most public moment for MEV-resistance demand. The 6 RLN names predate the cluster as foundational primitives.
Real on-chain footprint
15 of 15 names already resolve via ENS today (eth.limo). On-chain text records classify each by function. Verifiable, queryable, integrated into wallets and explorers.
Predictable cost
$78,500/yr for the full 15-namespace stack. Tier-based pricing. Same rate for any team that asks. No haggling.

06Common Questions

Why these 15 names specifically?

Three distinct sub-clusters that together cover the full MEV-defense stack. The 5 CHAIN.MEV names are the user-facing identity layer (sandwichprotection, mevshield, antimev, etc.). The 4 SECURITY.MEMPOOL/PRIVACY names are the substrate where encryption happens. The 6 RLN names are the Vac/Waku-research cryptographic primitives that make the substrate possible. Three layers, one defense.

Can I lease just the MEV-defense layer without the RLN backing?

Yes. Each name is independently lease-eligible. Most teams will start with 1–3 names that match their architecture (a wallet might just lease sandwichprotection.eth; a relay operator might want encryptedrelay.eth + mempoolencryption.eth). The full-stack framing is for teams building the entire MEV-defense surface, not a lock-in.

What does "lease" actually mean here?

You get exclusive subdomain rights under the parent name (e.g., your project becomes team.encryptedrelay.eth) plus the ability to mint additional subdomains as your infrastructure grows. The parent name stays in the registry — you don't buy the parent, you lease the subdomain space.

Is this stack tied to a specific MEV-defense protocol like Flashbots or SUAVE?

No. These names are vendor-neutral. They describe primitives at the protocol level — what the things ARE, not who runs them. Flashbots, SUAVE, Shutter, Veiled, and any future MEV-defense protocol are all welcome to lease subdomains under these names. The registry is infrastructure, not a brand.

When does this go live?

ENSv2 launches the subdomain-leasing primitives we'd use for full automation. ENS team has stated 2026 launch is on track ↗. Until then, leases are pre-arranged via direct contact. Reserve now to be in the first batch.

Is this the only stack you offer?

No. CPR has 44 ontological stacks across the portfolio of over 2,750 names. The other Featured Stacks: ZK Rollup Stack, Oracle Network Stack, Identity Stack, Restaking Stack, and API Infrastructure Stack. Browse all 15 verticals or the full registry.
