Mitosis Architecture

The Mitosis Liquidity Protocol is composed of the Mitosis Vaults, the Mitosis Chain, the Hyperlane AMB, and the Mitosis ISM.

1. Mitosis Vault

The Mitosis Vaults are where liquidity is kept safe. These are smart contracts deployed on each network supported by the Mitosis Liquidity Network.

For Liquidity Providers, these vaults are the gateway to minting and redeeming assets.

For Cross-chain Users, these are the initiating and terminating points of the interaction with Mitosis Liquidity Protocol for cross-chain activities.

Gateway to miAssets

On each supported network, Liquidity Providers (LPs) deposit their assets into the Mitosis Vault. The Mitosis Vault securely stores the assets and initiates the miAsset minting process.

LPs receive miAssets at a 1:1 ratio to their deposited principal assets. (e.g. deposit eETH, receive mieETH). With these miAssets, LPs can engage in various DeFi activites.

When LPs wish to reclaim their principal assets, their miAssets are burned, and the original assets are withdrawn from the Mitosis Vault.

Facilitating Cross-Chain Activities

Cross-chain Users interact with the Mitosis Vault when facilitating the Mitosis Liquidity Protocol for cross-chain activities. For example, to trigger a cross-chain transfer, users deposit assets into the Mitosis Vault on the source chain.

Eventually, the Mitosis Vault on the destination chain sends the corresponding assets to the users, finalizing the cross-chain transfer. (More about this: link to Transaction Flow)

2. Mitosis Chain

The Mitosis Chain is an EVM-compatible Cosmos chain. It plays a dual role: incubating a variety of DeFi protocols and acting as a source of truth for cross-chain activities.

Mitosis Ecosystem

The Mitosis Chain aims to nurture a broad spectrum of DeFi protocols, thereby creating the Mitosis Ecosystem.

For Liquidity Providers, this ecosystem is a particularly interesting place to utilize miAssets, as it brings together assets from various networks in the form of miAssets. (More about this: link to miAssets section).

For Cross-chain Users, the DeFi protocols within the Mitosis Ecosystem facilitate the execution of various cross-chain activities. (More about this: link to Scalability in Network section).

Mitosis Ledger Module

Operating cross-chain activities is challenging because state changes occur on different chains, resulting in numerous sources of truth.

To ensure the viability of certain cross-chain activities and to prevent users from incurring unnecessary gas costs, networks must monitor the Mitosis Vaults on every chain connected with the Mitosis Liquidity Network. However, as the number of supported networks grows, this task becomes exponentially more inefficient and even impossible.

To solve this issue, the Mitosis Chain keeps the Mitosis Ledger - the common source of truth. All cross-chain activities pass through the Mitosis Chain, which records these activities on the Mitosis Ledger. The Mitosis Ledger ensures a reliable source of truth; networks only need to refer to the Mitosis Chain.

3. Hyperlane AMB

Every transaction involving multiple chains and rollups requires data exchange between different networks. This data exchange is facilitated by arbitrary message bridges(AMBs).

Liquidity network also requires an AMB and choosing the right one is crucial. This is because the range of networks a liquidity network can support and the security level depend on the AMB.

Mitosis leverages Hyperlane AMB, which supports permissionless interoperability and modular security. Permissionless interoperability enables Mitosis to extend to any desired rollup or chain. Utilizing the modular security framework, the Hyperlane Interchain Security Module, Mitosis can tailor its security measures to the desired level and, if necessary, implement multiple, battle-tested security models concurrently.

Hyperlane has introduced the Warp Route for asset transfers. Warp Route operates using the burn-and-mint and lock-and-mint methods. In contrast to these methods, the lock-and-unlock method requires a significant amount of liquidity. The Mitosis Liquidity Protocol, with its scalable liquidity, is set to be the Hyperlane-based implementation of the lock-and-unlock cross-chain transfer.
