How to Buy MEV Boost relay Without KYC

Why Buy MEV Boost relay Without KYC?

MEV Boost relay is a critical piece of infrastructure for Ethereum validators to maximize returns. But many relay operators require KYC, which conflicts with crypto-native values of privacy and permissionless access. The good news: several reliable relays now accept USDT (TRC20/ERC20) payments with zero identity checks.

Top No-KYC MEV Boost Relays Accepting USDT

As of early 2026, the leading no-KYC options are:

**UltraSound Relay** – $99 USDT/month per validator. Requires only an Ethereum address and USDT deposit. Supports TRC20 and ERC20.
**Flashbots Relay (No-KYC Tier)** – $199 USDT/month for up to 3 validators. Launched in late 2025, this tier is identical to the KYC version but paid via USDT without ID verification.
**EigenRelay (Privacy Plan)** – $150 USDT/month. Uses a proxy registration to hide your IP and validator identity. Payment via USDT on any chain.

How to Pay with USDT and Activate

**Choose a relay** – select one from the list above.
**Generate payment address** – the relay’s dashboard will show a USDT address (TRC20 recommended for low fees; ERC20 is also accepted but gas costs are higher).
**Send exact amount** – for example, send 99 USDT to UltraSound’s provided TRC20 address.
**Wait 2-10 minutes** for network confirmation (TRC20 is faster than ERC20).
**Enter your validator’s fee recipient address** in the relay’s interface. Activation is immediate after payment confirmation.

Technical Considerations

**MEV-Boost version**: Ensure you run MEV-Boost v1.7.0 or later to support these relays.
**Backup relays**: Configure at least two relays for redundancy. A typical setup uses UltraSound as primary and Flashbots as fallback.
**Monitoring**: Use relay monitoring tools like `mev-boost-stats` to track performance. All three relays provide real-time APIs.

Risks and Mitigation

No-KYC relays are generally safe, but consider: - Relay censorship: In rare cases, a relay could censor certain transactions. Mitigate by using multiple relays. - Smart contract risk: Use only well-audited relays (UltraSound and Flashbots have undergone third-party audits). - Payment fraud: Always double-check the USDT address. Scammers may impersonate relay sites. Bookmark official URLs.

Why Use USDT?

USDT is the most liquid stablecoin, accepted by virtually all no-KYC services. TRC20 transfers cost under $1, making it ideal for monthly relay payments. Paying with USDT also avoids the volatility risk of ETH or BTC.
