# MistCoin ($WMC) — Complete Reference > The first ERC-20 token prototype, deployed by the Ethereum team on November 3, 2015 — 16 days before the ERC-20 standard was proposed. ## Overview MistCoin is the most historically significant ERC-20 token on Ethereum. It was deployed on November 3, 2015, by the Ethereum Foundation's Mist team as a prototype to test standardized token creation in the Mist Browser (Ethereum's official dApp browser). Sixteen days later, on November 19, 2015, Vitalik Buterin and Fabian Vogelsteller formally proposed the ERC-20 standard (EIP-20), which codified the token interface that MistCoin had already implemented. Every ERC-20 token on Ethereum — hundreds of thousands of tokens representing hundreds of billions of dollars in value — follows the standard that MistCoin prototyped. ## Token Details | Field | Value | |-------|-------| | Name | MistCoin | | Ticker | MC (original), WMC (wrapped) | | Deployment date | November 3, 2015 | | Deployment block | #424,961 | | Original contract | 0xf4eCEd2f682CE333f96f2D8966C613DeD8fC95DD | | Wrapped contract | 0x7Fd4d7737597E7b4ee22AcbF8D94362343ae0a79 | | Wrapper contract | 0x67c6ec7e6a0e2e2d345de398d3ac607364b0ed30 | | Total supply | 1,000,000 MC | | Decimals | 2 | | Chain | Ethereum mainnet | | Standard | Pre-ERC-20 (implements balanceOf, transfer, Transfer event) | ## Historical Timeline ### June 17, 2015 — Vitalik begins standardization Vitalik Buterin begins externally proposing the first token standards in crypto on the Ethereum Wiki ("Standardized Contract APIs"). Through July 5, 2015, Vitalik expands on standardization ideas including standard decentralized exchanges and registries — the building blocks for what would become MetaMask, Uniswap, and ENS.

This was his last commit to the standards documentation before deploying MistCoin and shipping the token creation feature in the Mist Browser.

This update allowed anyone to create standardized tokens through a GUI interface.

It implements the core token interface: balanceOf mapping, transfer function, and Transfer event — the same interface that would become ERC-20.

This proposal codifies the interface pattern that MistCoin had already implemented 16 days earlier.

MistCoin's original 2015 contract only contains `balanceOf` and `transfer` functions. The full ERC-20 standard requires additional functions (`approve`, `transferFrom`, `allowance`) for tokens to be tradable on decentralized exchanges. A wrapper contract was created to allow MistCoin holders to wrap their tokens into a fully ERC-20-compliant contract (WMC) that can be traded on Uniswap and other DEXes. Holders can wrap and unwrap freely at any time. ## Trading Information - **DEX:** Uniswap V2 (Ethereum mainnet) - **Trading pair:** WMC/WETH - **Uniswap pool:** 0x7c2caefe7ef6f5edf53cdcea8d60ea615f102e0c - **Buy link:** https://swap.cow.fi/#/1/swap/WETH/WMC - **DexScreener:** https://dexscreener.com/ethereum/0x7c2caefe7ef6f5edf53cdcea8d60ea615f102e0c - **CoinMarketCap:** https://coinmarketcap.com/dexscan/ethereum/0x7c2caefe7ef6f5edf53cdcea8d60ea615f102e0c/ ## Notable Holders - Bureau of Internet Culture (BIC) — Added MistCoin to their DAO treasury ## Website Tools ### Origin Checker Compare any ERC-20 token's deployment date to MistCoin's.

MistCoin was the first token deployed on Ethereum as a test for the ERC-20 standard. It served as a proof of concept for tokenized assets on Ethereum, influencing the development of countless tokens that followed. It was deployed on November 3, 2015, by the Mist team at the Ethereum Foundation. ### What was the first token on Ethereum? MistCoin, deployed on November 3, 2015, is the oldest surviving token that implements the core ERC-20 interface (balanceOf, transfer, Transfer event). It was created by Fabian Vogelsteller and the Mist team as the reference implementation for the Ethereum Wallet's custom token feature. ### Who created the ERC-20 standard? The ERC-20 standard (EIP-20) was formally proposed on November 19, 2015, by Vitalik Buterin and Fabian Vogelsteller. However, the standardization process began months earlier: Vitalik started the "Standardized Contract APIs" wiki page in June 2015, and Fabian made critical implementation commits through October 2015. MistCoin, deployed November 3, 2015, was the working prototype of this standard. ### What is the ERC-20 token standard? ERC-20 defines a set of rules for creating tokens on Ethereum. These rules ensure tokens are interoperable with each other and with decentralized applications (dApps), providing consistency in how tokens function across wallets, exchanges, and DeFi platforms. ### How many ERC-20 tokens exist today? Millions of ERC-20 tokens have been created on Ethereum, representing hundreds of billions of dollars in combined market capitalization. Every one of them follows the standard that MistCoin prototyped in November 2015. ### Can I buy MistCoin? Yes. Wrapped MistCoin ($WMC) is tradable on Uniswap and other Ethereum DEXes.
