What Is ICON?

ICON is winding down. The network entered "economic shutdown" on March 26, 2026, halting all ICX emissions and staking rewards, and is scheduled to shut down permanently on December 31, 2026, after which the chain will become a read-only archive for historical transaction lookups. ICON and Balanced have merged into SODAX, and ICX is migrating 1:1 into the SODA token. The network is still running today and the migration is underway, but the shutdown is scheduled and staking rewards have already ended. This article is preserved for reference.

ICON (ICX) was a blockchain platform developed by the ICON Foundation, based in South Korea, in collaboration with ICONLOOP (originally known as theloop), a fintech company specializing in enterprise blockchain solutions. The project was founded by Min Kim and launched in 2017 with the vision of "hyperconnecting the world," creating a network where independent blockchain communities used by governments, banks, hospitals, universities, and businesses could transact and share data with each other while maintaining their own governance and rules. The ICON Foundation raised funds through a token sale in September 2017 that closed at its target of 150,000 ETH, distributing 400,230,000 ICX tokens with 50% allocated to the sale, 16% to reserves, 14% to the foundation, 10% to community and strategic partners, and 10% to the team, advisors, and early contributors.

ICON's architecture was built around the concept of the "ICON Republic," a decentralized network that connected independent blockchain communities through a central nexus. Each community, whether a consortium of banks, a group of hospitals, or a university network, operated its own blockchain with its own consensus rules and governance. These communities connected to the ICON Republic through portals called C-Reps (Community Representatives), which participated in the Republic's governance. The underlying blockchain engine was loopchain, developed by ICONLOOP, which used the Loop Fault Tolerance (LFT) consensus algorithm optimized for enterprise-grade performance.

The ICON network used a consensus mechanism called Delegated Proof of Contribution (DPoC), a variant of Delegated Proof of Stake. ICX holders could stake their tokens and delegate them to validators known as P-Reps (Public Representatives) who produced blocks and governed the network. There were 22 main P-Reps responsible for block production and up to 78 sub P-Reps providing additional network support. Smart contracts on ICON, called SCOREs (Smart Contracts on Reliable Environment), could be written in Java or Python, lowering the barrier for enterprise developers already familiar with these languages.

A core technology of ICON was the Blockchain Transmission Protocol (BTP), which enabled trustless cross-chain communication between heterogeneous blockchains. Unlike bridge solutions that rely on multi-signature schemes or trusted relayers, BTP used on-chain verification to confirm transactions across chains without centralized intermediaries. BTP 2.0 expanded these capabilities to support connections with major networks beyond the ICON ecosystem. The project also explored subnet architecture through ICE and SNOW, application-specific networks designed for specialized use cases like DeFi and gaming.

ICON established strong roots in South Korea, with ICONLOOP deploying enterprise blockchain solutions for major institutions including the Seoul Metropolitan Government, Samsung, and several Korean insurance and securities companies. ICONLOOP's blockchain-based decentralized identity (DID) system provided digital authentication services used in government and financial contexts. The ICON DeFi ecosystem included Balanced (a decentralized exchange and stablecoin protocol), OMM Finance (a lending and borrowing platform), and Craft (an NFT marketplace), accessible through the Hana wallet, the official ICON browser extension formerly known as ICONex.

What Happened To ICON?

ICON is winding down in stages over 2026, with the network merging into SODAX and ICX migrating into the SODA token:

  1. March 26, 2026: The ICON Network entered "economic shutdown." All ICX emissions and staking rewards were halted, ending the network's staking and reward mechanics even though the chain kept producing blocks.
  2. 2026: ICON and Balanced merged into SODAX (Soda Xchange). Holders can migrate ICX into the SODA token at a fixed 1:1 ratio through the official migration dashboard at sodax.com.
  3. September 30, 2026 (scheduled): Two-way swaps between ICX and SODA are due to be disabled. From this date, only one-way ICX to SODA conversions are planned to be supported.
  4. December 31, 2026 (scheduled): The ICON Network is scheduled to shut down permanently and the chain will become a read-only archive for historical transaction lookups. After this date, ICX can no longer be migrated to SODA.

The steps dated in the future above are scheduled and had not occurred as of this writing. The network is still running today.

What About ICX Tokens?

Migrating ICX to SODA

The intended path for ICX holders is migration into the SODA token via SODAX. The official migration dashboard at sodax.com converts ICX to SODA at a fixed 1:1 ratio. Two-way swaps between ICX and SODA are available until September 30, 2026, after which only one-way ICX to SODA conversions are planned, with a final cutoff on December 31, 2026. Holders who do not migrate before the shutdown will be left holding ICX on a chain that is scheduled to become a read-only archive.

ICX Wallets

ICX can still be held in the Hana wallet, the official ICON browser extension formerly known as ICONex, and on Ledger hardware wallets for cold storage. Because staking rewards ended in March 2026, holding ICX no longer earns network rewards, and the staking, delegation, and governance features that depended on active emissions are no longer meaningful.

Can You Still Buy ICON?

ICX still trades on some centralized exchanges and within the ICON ecosystem, but the network behind it is being shut down. Anyone acquiring ICX should understand that emissions and staking rewards ended in March 2026, the chain is scheduled to become a read-only archive on December 31, 2026, and the project's forward path is migration into the SODA token rather than continued ICON development.

Rather than accumulating ICX, existing holders are generally directed to migrate their tokens 1:1 into SODA through the official dashboard at sodax.com before the migration deadlines. There is no active ICON protocol revenue, no staking mechanism, and no ongoing network reward to support holding ICX beyond the wind-down period.

Latest ICON News

In 2026, ICON moved from an active interoperability platform into a scheduled wind-down. On March 26, 2026, the network entered "economic shutdown," halting all ICX emissions and staking rewards. ICON and the Balanced DeFi protocol merged into SODAX (Soda Xchange), with ICX migrating into the SODA token at a fixed 1:1 ratio. The ICON Foundation set a final date for the network's permanent shutdown on December 31, 2026, after which the chain will be switched to a read-only archive for historical transaction queries. Two-way ICX and SODA swaps are available until September 30, 2026, with only one-way ICX to SODA conversions afterward and a final migration cutoff at the end of 2026. The project's community and development activity has shifted to SODAX, with social channels moving to the SODA Holders account on X and the SODAX Discord.
