SMC: The Blockchain Where Your Phone Number is Your Wallet

Introducing Short Messaging Chain (SMC) - The First Blockchain Built For The Other 7 Billion-

The global financial system has a blind spot. While DeFi protocols race to build faster DEXs,
lower gas fees, and more sophisticated yield strategies, 1.4 billion people on earth still
can't access any of it- not because they lack the desire, but because they lack a smartphone,
a bank account, or the technical knowledge to manage a seed phrase.

Short Messaging Chain (SMC) is built to fix that.



WHAT IS SMC?

SMC is an EVM-compatible Layer 1 blockchain that maps every user's E.164 phone number directly
to an on-chain wallet address. No app. No browser extension. No seed phrase written on a piece
of paper. Your phone number is your wallet- and to send, receive, or swap crypto, you simply
send a text message.

This isn't a custodial service. SMC is a fully decentralized protocol. Private keys are derived
from the user's credentials in under 500 milliseconds and are never stored anywhere on the
network. The user retains full, non-custodial ownership of their assets at all times.



HOW IT WORKS

Sending crypto on SMC is as simple as sending a Venmo request - but without Venmo.

A user texts: SEND 50 SMC +(NUMBER)

The SMC gateway, which interfaces with the blockchain directly, confirms the transaction,
requests a PIN to authorize it, and broadcasts the signed transaction on-chain. The recipient
at +(NUMBER) receives the funds in their wallet - which was automatically provisioned
the first time anyone sent them anything, simply by virtue of their phone number existing
in the E.164 namespace.

No onboarding flow. No KYC. No app download. The act of receiving a text is the act of
opening a wallet.



THE TECHNOLOGY

SMC is a fork of go-ethereum, fully EVM-compatible. Every Solidity smart contract, every
DeFi primitive - Uniswap, Aave, Compound - works natively on SMC without modification.

Key technical parameters:
- Block time: 3 seconds
- EVM compatible: yes (full go-ethereum fork)
- Key derivation: sub-500ms, ephemeral (never persisted)
- Sub-wallet architecture: users can spawn infinite child wallets from a single phone number
(separate wallets for business, savings, trading - all from one SMS thread)
- Open source

The sub-wallet system is particularly powerful. A merchant in Lagos can run a business wallet
and a personal wallet from the same SIM card, segregating funds the same way a Western user
might use separate checking and savings accounts - without ever needing a bank.



WHY SMS?

SMS has a near-perfect penetration rate in markets where banking does not. Nigeria, Indonesia,
Bangladesh, Ethiopia - these are countries where feature phones outnumber smartphones and
mobile money is already the dominant financial paradigm. M-Pesa, the SMS-based mobile money
platform launched in Kenya in 2007, now moves more than $314 billion per year.

SMC brings that same frictionless experience to a trustless, decentralized blockchain -
combining the accessibility of M-Pesa with the programmability of Ethereum.



THE MARKET OPPORTUNITY

The numbers are stark:

- 1.4 billion unbanked adults globally (World Bank, 2021)
- 5.4 billion mobile phone subscriptions worldwide
- $800B+ annual remittance market, averaging 6% in fees
- DeFi total value locked: $100B+ - almost entirely inaccessible to the unbanked

SMC is positioned at the intersection of all four. The addressable market is not the
existing DeFi user - it is everyone who has ever needed to send money internationally
and paid Western Union's fee to do it.



NON-CUSTODIAL BY DESIGN

A common critique of SMS-based financial systems is centralization risk. If a gateway
controls the keys, it controls the money.

SMC addresses this directly. The gateway is a signing interface only - it never holds
private keys. Keys are derived on demand, used to sign a transaction, and immediately
discarded. The blockchain itself is fully decentralized. No single entity, including the
SMC development team, can freeze, reverse, or seize user funds.

This is DeFi - delivered via a 160-character text message.



FOR INVESTORS

SMC represents a category-defining opportunity: the first blockchain protocol purpose-built
for the SMS-first, unbanked global majority. The infrastructure is built. The EVM compatibility
means the full DeFi ecosystem is available from day one. The go-to-market is any market where
a phone signal exists and a bank branch does not.

ABOUT SHORT MESSAGING CHAIN

Short Messaging Chain (SMC) is a decentralized, EVM-compatible Layer 1 blockchain that uses
the global E.164 phone number namespace as its identity and wallet layer. SMC enables anyone
with a mobile phone to send, receive, and interact with DeFi applications via SMS - no
smartphone, no app, and no seed phrase required.

Short Messaging Chain (SMC) is a blockchain infrastructure company building the world's
first decentralized financial network designed around the mobile phone number.

We exist because the promise of decentralized finance has not reached the people who need
it most. The 1.4 billion adults without a bank account are not unbanked by choice - they
are unbanked by friction. Smartphones are expensive. Seed phrases are complex. Gas fees
are opaque. DeFi, for all its innovation, remains inaccessible to the majority of the
world's population.

SMC removes every layer of that friction.
