What is Orbiscribe?

It enables anyone to permanently inscribe data - text, images, SVG, code, HTML, JSON, or any file - directly on-chain using EVM transactions.

Orbiscribe also introduces B20, a fungible token standard whose minting, pricing, and fair-launch rules are enforced directly by smart contracts — open minting on a bonding curve with built-in anti-bot fees.

Inscriptions are permanent, open, and indexed by the Orbiscribe Explorer.

[001] How It Works

Orbiscribe records arbitrary data on-chain through transaction calldata, while B20 token economics are enforced by on-chain contract logic around every mint.

Inscriptions can be simple raw data such as text, SVG, images, or structured JSON for NFT collections and B20 tokens.

Every valid inscription is indexed, rendered, and displayed inside the Orbiscribe Explorer.

Once confirmed on-chain, the inscription becomes a permanent artifact.

{
  "p": "b20",
  "op": "deploy",
  "tick": "ORB",
  "max": "21000000",
  "lim": "420"
}

$ORB is the first B20 token. Each mint issues 1,000 tokens on a bonding curve that starts at 0.0001 ETH and climbs to ~0.001 ETH as the supply fills.

[002] Key Features

On-Chain Inscriptions: Data is written directly into EVM transactions, without relying on external storage like IPFS.

Fair Launch Mechanics: No pre-mines, no private allocations, no whitelist advantage. Every user mints under the same bonding-curve rules.

On-Chain Enforcement: B20 launches enforce bonding-curve pricing, fees, and fair-launch rules at the contract level.

Raw Inscriptions: Users can inscribe raw data directly. Text, SVG, images, JSON, HTML, and code can be written on-chain.

B20 Fungible Tokens: Deploy, mint, and transfer tokens with bonding-curve pricing enforced on-chain. Tickers are first come, first served; enforced fees curb spam and bot abuse.

02 Creating an Inscription

To create an inscription on Base, you need a Base-compatible wallet with enough ETH or Base testnet gas for transaction fees.

Steps: Connect your wallet on the Orbiscribe Inscribe page. Choose your format: text, image, SVG, JSON, HTML, or file upload. Upload or paste your content. Review the platform fee and network gas. Click Inscribe. Your wallet signs the transaction. Wait for Base confirmation. Your inscription becomes permanently stored on-chain.

03 Supported Formats

Maximum size may be constrained by Base transaction limits and gas costs.

Orbiscribe is an experimental protocol - not a financial product. No returns should be expected.

04 Fees & Costs

Orbiscribe uses a hybrid fee model.

Raw inscriptions are kept simple and accessible, while B20 token operations require enforced fees to reduce spam and bot activity.

Inscriptions

Raw inscriptions are visible in the Orbiscribe Explorer once indexed. The indexer is open and reads valid Orbiscribe inscription data from Base transactions.

B20 Tokens

B20 fees are strictly enforced. Operations without the correct fee are ignored by the indexer. This prevents bots from minting entire supplies for free.

Other

All fee-based operations are handled through protocol-recognized transactions. If a transaction fails, the operation is not indexed.

05 Protocol Specification

All Orbiscribe operations use Base transactions with structured protocol payloads.

Protocol identifier:

{
  "p": "orbiscribe"
}

For B20 tokens:

{
  "p": "b20"
}

06 Operations

Example: Inscribe Operation

{
  "p": "orbiscribe",
  "op": "inscribe",
  "type": "image/svg+xml",
  "name": "My First Orbiscribe",
  "data": "<svg>...</svg>"
}

Example: Transfer Operation

{
  "p": "orbiscribe",
  "op": "transfer",
  "symbol": "ORB",
  "id": "42",
  "to": "0x0000000000000000000000000000000000000000"
}

07 B20 Token Standard

B20 is a fungible token standard on Base, inspired by BRC-20 on Bitcoin.

Anyone can deploy and mint tokens using structured Orbiscribe JSON payloads.

Key Rules: Ticker is 4-5 uppercase letters (A-Z), first come first served, first valid deploy claims ticker forever, fixed 8 decimals, deploy/mint/transfer fees enforced, operations without required payment ignored, fair launch only, no pre-mines.

08 Deploy a B20 Token

Create a new fungible token.

Fee: 0.00015 ETH / Base gas equivalent

{
  "p": "b20",
  "op": "deploy",
  "tick": "ORB",
  "max": "21000000",
  "lim": "420"
}

If the ticker already exists or the required fee is not paid, the deploy is ignored by the indexer.

09 Mint B20 Tokens

Mint tokens from an existing deployment.

Fee: 0.00015 ETH / Base gas equivalent per mint

{
  "p": "b20",
  "op": "mint",
  "tick": "ORB",
  "amt": "420"
}

Validation Rules: ticker must exist, amount must be less than or equal to mint limit, total minted supply must not exceed max supply, required mint fee must be paid, and transaction must be valid on Base.

Anti-Bot Design: every mint requires a protocol fee. This makes large-scale bot minting expensive and helps keep launches fair for normal users.

10 Transfer B20 Tokens

Send B20 tokens to another address.

Fee: 0.0005 ETH / Base gas equivalent

{
  "p": "b20",
  "op": "transfer",
  "tick": "ORB",
  "amt": "500",
  "to": "0x0000000000000000000000000000000000000000"
}

The indexer verifies the sender's balance using the transaction sender address. You can only transfer tokens you own.

11 Transfer Inscriptions

Transfer ownership of any Orbiscribe inscription - text, SVG, image, JSON, HTML, or code - to another wallet.

Use the inscription ID from the Orbiscribe Explorer.

{
  "p": "orbiscribe",
  "op": "transfer",
  "id": "442",
  "to": "0x0000000000000000000000000000000000000000"
}

Only network gas is required unless the protocol defines an additional transfer fee. The indexer verifies ownership from the transaction sender. You can only transfer inscriptions you own.

12 Marketplace

The Orbiscribe Marketplace allows listing, buying, and trading inscriptions. All marketplace actions are represented through on-chain Orbiscribe operations and indexed by the protocol.

v1: OTC Trading - transfers are peer-to-peer. Buyers and sellers coordinate off-chain through Discord, Telegram, X, or other channels, then settle ownership on-chain.

v2: Escrow Marketplace (coming soon) - list to buy flow with escrow-style verification. The buyer pays, the indexer verifies payment, and ownership transfers according to marketplace rules.

Disclaimer: Orbiscribe is an experimental inscription and token protocol built for Base. It is not a financial product. B20 tokens are experimental assets. No profit, return, or future value should be expected.
