Deploy an SRC20 in 60 Seconds

Deploy a private SRC20 token on Seismic testnet with a single command — no compiler required

The SRC20 Factory is a pre-deployed contract on Seismic testnet that lets anyone create a private token without installing sforge or writing a single line of Solidity. You give it a name, symbol, and supply; it hands back a deployed token address.

Quickstart

bunx create-src20

That's it. The CLI walks you through the rest interactively, or you can pass everything up front:

bunx create-src20 \
  --name "My Private Token" \
  --symbol "MPT" \
  --supply 1000000 \
  --key 0xYourPrivateKey

Example output:

  Create SRC20 Token on Seismic

--symbol

Token symbol

--supply

Initial supply in whole tokens (multiplied by 10¹⁸ internally)

--key

0x-prefixed 64-character hex private key

--rpc

Supply is always treated as whole tokens. Passing --supply 1000000 mints 1,000,000 × 10¹⁸ base units, using 18 decimals.

What you get

Every deployed token is a full SRC20Token contract — Seismic's private variant of ERC20. Balances, transfer amounts, and allowances are encrypted on-chain using suint256 shielded types. Outside observers see only encrypted ciphertext. The token deployer becomes the owner and has exclusive mint and burn rights.
