What is Multichain (MULTI)?

Quick Facts

• Protocol type: Cross-Chain Router Protocol (CRP)
• Original name: Anyswap (founded July 2020)
• Rebranded: To Multichain in 2022
• Governance token: MULTI (replaced ANY at a 1:1 ratio)
• Key technology: Secure Multi-Party Computation (SMPC) node network
• Funding: $60 million raised in 2021 at a $1.2 billion valuation
• Status: Operations ceased in July 2023 following a major exploit and founder disappearance

Introduction

Multichain is an open-source cross-chain router protocol designed to connect dozens of different blockchain networks, allowing users to transfer tokens freely between them. Its native governance token, MULTI, gives holders the right to vote on protocol decisions and participate in community governance.

The project positioned itself as the 'ultimate router for Web3,' aiming to solve one of blockchain's most persistent challenges: the inability of isolated networks to communicate and share assets.

History & Background

Multichain began its life as Anyswap, a decentralized cross-chain exchange protocol launched in July 2020. In early 2021, the team pivoted away from DEX functionality and focused entirely on cross-chain bridging infrastructure.

In 2021, the project raised a $60 million financing round at a valuation of $1.2 billion, led by Binance Labs. The platform rebranded to Multichain in 2022, reflecting its broader infrastructure ambitions. In 2023, the project's founder went missing, leading to a major operational crisis and a large-scale exploit that resulted in substantial user fund losses. Multichain officially ceased operations in July 2023.

How Multichain Works

Multichain's core innovation is its Cross-Chain Router, which automatically selects the best method to move tokens between blockchains. It operates using two primary mechanisms:

• Lock and Mint (Bridging): When a token does not natively exist on the destination chain, Multichain locks the original token in a smart contract and mints a wrapped equivalent on the target chain, maintaining a 1:1 ratio.
• Liquidity Pools: When a token already exists natively on both chains, Multichain uses cross-chain liquidity pools to facilitate the swap without minting new tokens.

Security relied on a network of SMPC (Secure Multi-Party Computation) nodes, where no single node held a complete private key, eliminating a single point of failure.

Tokenomics

MULTI serves as Multichain's governance token, allowing holders to vote on protocol upgrades, fee structures, and ecosystem proposals. Holders of the predecessor token ANY could convert to MULTI at a 1:1 ratio during the transition.

Token utility also extended to staking, where participants could lock MULTI to help secure the network and earn rewards. Liquidity providers who deposited assets into cross-chain pools earned a share of transaction fees generated by the protocol.

Ecosystem & Use Cases

At its peak, Multichain supported over 60 blockchains and more than 1,600 tokens, making it one of the broadest cross-chain infrastructure providers in the DeFi space. Use cases spanned:

• DeFi: Moving assets between chains to access different lending, yield, and trading protocols.
• NFT bridging: Enabling NFT transfers across chains using ERC-721 and ERC-1155 standards.
• Developer infrastructure: Allowing projects to extend their token presence to new blockchains without building custom bridges.

Team, Governance & Community

The protocol was founded under the Anyswap brand and governed through MULTI token voting. Community governance was intended to guide decisions on supported chains, fee parameters, and protocol upgrades. The SMPC node network was partially operated by community members and institutional partners to promote decentralization.

Following the founder's disappearance in 2023, governance effectively collapsed, and the team was unable to maintain normal operations.

Advantages

• Broad chain support: Connected over 60 blockchains, one of the widest coverage in the industry at its peak.
• Dual bridging methods: Both lock-and-mint and liquidity-pool routing gave flexibility for different token types.
• Decentralized security model: SMPC nodes distributed key management, avoiding a single point of failure.
• NFT interoperability: Native support for cross-chain NFT transfers was a differentiating feature.

Risks & Challenges

• Project cessation: Multichain officially stopped operations in July 2023; the protocol is no longer actively maintained.
• Exploit history: A major bridge exploit resulted in over $130 million in unauthorized withdrawals from custody wallets.
• Founder risk: The disappearance of the project's key founder exposed the protocol's reliance on centralized leadership.
• Market confidence: MULTI token liquidity persists on-chain, but market confidence remains significantly impaired.
• Bridge security risks: Cross-chain bridges are inherently high-value targets; custody of locked assets creates systemic vulnerability.

Long-Term Vision

Multichain's original vision was to serve as the foundational routing layer for a fully interconnected Web3 ecosystem. While the protocol itself is no longer operational, its design philosophy — combining SMPC security, multi-method routing, and broad chain coverage — influenced the broader conversation around cross-chain infrastructure.

Any potential revival of the Multichain ecosystem would depend on community or third-party intervention. The MULTI token remains on-chain as a historical artifact of one of the most ambitious cross-chain bridging projects of its era.
