Your inbox has a cover charge.

ETHTEL combines a fixed-supply ERC-20 with a live on-chain contact directory. Register a handle, publish where you can be reached, and set the ETHT price required to ping you.

The protocol

Attention becomes an addressable market.

The directory does not sell access to a platform. It lets each listing decide what unsolicited contact costs, then settles that payment directly between sender and recipient.

Junk cannot justify the price. Real messages can.
01

Register a handle

One Ethereum address claims one unique handle and publishes a contact URI such as https:, mailto:, or nostr:.

02

Set the ping price

The listing owner chooses the ETHT price required to ping the address. Zero keeps the listing open; a higher price raises the bar for unsolicited contact.

03

Pay the recipient

A ping transfers the listed amount from the sender directly to the recipient. TelDirectory holds no funds and takes no protocol fee.

04

Deliver the introduction

The on-chain event is the settlement and public record. Optional relay software can forward the introduction as an encrypted Nostr DM; the conversation can then continue at the published contact URI.

System layers

Ethereum settles. Open protocols deliver.

The contracts are live and self-contained. Relay and MCP components are optional client infrastructure; they do not alter token supply or custody protocol funds.

ETHT token

Fixed-supply ERC-20 with ERC-2612 permit support. The contract contains no owner or administrator functions.

Live mainnet

TelDirectory

Stores handles, contact URIs, and ping prices. A paid ping transfers ETHT directly to the listing owner and emits the message on-chain.

Live mainnet

Relay

Mainnet-aware reference software watches Pinged events and can publish encrypted Nostr DMs when an operator configures a relay identity. Delivery depends on that running instance and the recipient's Nostr client.

Open software

MCP server

Seven tools let MCP-capable AI agents look up listings, register, update, send capped paid pings, and check incoming pings. Read operations need no wallet; write operations require the agent's funded wallet.

ETHT is a ticker, not an identity. Confirm the complete Ethereum mainnet address before interacting.

Token facts

Simple by construction.

ETHT does not promise yield, equity, redemption, or ownership in ethereum.tel. Its defined protocol role is payment for directory pings.

Immutable total supply100METHT · 18 decimals
Creation

100% of supply was minted once to the deployer when the token contract was created on July 2, 2026.

Fundraising

No public sale, private sale, presale, ICO, IEO, launchpad, soft cap, hard cap, or fundraising was conducted.

Administration

No owner, mint, pause, blacklist, fee, or upgrade mechanism exists in the token contract.

Distribution

Current balances and holder concentration are public on Ethereum. Review the holder tab before acquiring ETHT.

Rights

ETHT conveys no company equity, revenue share, debt claim, guaranteed return, or redemption right.

Open market

ETHT/WETH trades on Uniswap.

The pair is permissionless. Price, liquidity, volume, and slippage change with market activity. Verify the token address and review the transaction before signing.

Transparency

What is live, and what is not.

Public information should distinguish deployed contracts from optional software and future operations.

Live on Ethereum

  • ETHT token and fixed supply
  • TelDirectory registration and lookup
  • Direct ETHT ping payments
  • ethtel handle at 100 ETHT per ping
  • Uniswap V2 ETHT/WETH pair

Operator-run software

  • Nostr delivery requires a configured, running relay instance
  • MCP write tools require an agent-controlled funded wallet
  • Neither component changes the token contract or takes custody through TelDirectory

Security posture

The contracts use OpenZeppelin 5.x primitives and passed the project's 12 automated tests. The contracts have not received an independent third-party audit. Source verification is not an audit.

Explorer status

Contract source is verified on Etherscan. The earlier token-profile metadata request was not accepted; a corrected public-information resubmission is being prepared.

Accountability

Public points of responsibility.

The protocol has no contract administrator, but the public project still identifies its communication channel and deployment wallet.

Questions

Plain answers.

Core limitations and definitions, without promotional shorthand.

Is ETHT issued by the Ethereum Foundation?

No. ETHTEL and ethereum.tel are independent and are not affiliated with, endorsed by, or operated by the Ethereum Foundation or ethereum.org.

Can anyone mint more ETHT?

No. The token minted 100,000,000 ETHT in its constructor. Its verified source contains no later mint function or administrator.

Where does a ping payment go?

TelDirectory transfers the listing's ETHT ping price directly from the sender to the listing owner. The contract does not retain the payment and does not take a fee.

Does the relay control the protocol?

No. The relay observes public Pinged events and optionally delivers encrypted Nostr messages. The token and directory continue to exist if a relay is offline.

Has ETHTEL been independently audited?

No. The source is public and verified, and the project test suite passes 12 tests, but no independent third-party audit is claimed.

Is ETHT an investment?

This page describes protocol software and an open market; it does not provide investment, legal, or tax advice. ETHT has no guaranteed value or return. Digital-asset markets can result in total loss.
