IOST Token Mapping: Historical Context and Current Status
IOST (Internet of Services Token) is a decentralized blockchain network designed to provide high throughput, scalability, and security to support large-scale decentralized applications (DApps). Its token "mapping" or "swap" operation specifically refers to the process of converting previously Ethereum-based ERC-20 tokens into native IOST mainnet tokens after the official launch of the IOST mainnet "Olympus v1.0" in 2019.
It is important to emphasize that this mainnet mapping was completed many years ago, and all IOST tokens currently in circulation are native mainnet tokens. Users no longer need to perform any mapping operations. This article aims to review this historical event and clarify its relevance to current IOST transactions.
Review of the 2019 IOST Mainnet Mapping
The IOST mainnet "Olympus v1.0" officially launched on February 25, 2019. Following this, the IOST team initiated the conversion of ERC-20 tokens to native mainnet tokens, a process that continued throughout 2019 to ensure all holders had ample time to complete the conversion. The core purpose of this mapping was to enable users to fully utilize various DApps within the IOST ecosystem and participate in mainnet functionalities such as staking, paying transaction fees, and more.
Primary methods of operation at the time:
- Through supported cryptocurrency exchanges: This was the IOST official recommended and primary method. Users simply deposited their ERC-20 IOST tokens into exchanges that supported mainnet mapping at the time (e.g., Binance, KuCoin, Huobi Global, OKEx, Upbit, etc.), and the exchanges would automatically complete the conversion. Users typically did not need to perform additional actions, as the exchange's deposit system would automatically identify and process the conversion.
- Official token mapping tool: IOST also provided a dedicated token mapping tool. Users could connect their Ethereum wallet (such as MetaMask or MyEtherWallet) to this tool, specify the amount of ERC-20 tokens to be swapped, and then send them to a designated address. The tool would automatically send the corresponding amount of native IOST tokens to the user's IOST wallet.
Important considerations:
For users holding ERC-20 IOST tokens in personal wallets (such as hardware wallets) who did not convert them through exchanges or the official tool within the specified timeframe, these old ERC-20 tokens would no longer be accepted by the IOST network, and their value might be affected. Therefore, timely completion of the mapping was crucial to ensure asset validity.
IOST Current Status and Market Overview
As of August 26, 2026, all IOST tokens have completed the mainnet conversion, and all tokens circulating in the market are native mainnet tokens. Currently, the price of IOST is approximately $0.00053233, with a 24-hour trading volume of about $33.5 million and a market capitalization of approximately $18.5056 million. Its circulating supply is approximately 34.7617 billion IOST, and the total supply is 90 billion IOST. IOST's all-time high price reached $0.129 (January 2018).
Currently, there are some third-party platforms offering "exchange" services for IOST with other cryptocurrencies, but this is a different concept from the 2019 ERC-20 to mainnet token "mapping," which is no longer required.
