Invariant

Invariant is a permissionless automated market maker (AMM) decentralized exchange built on Solana, designed around concentrated liquidity as its core mechanism. Originally launched on Solana mainnet in March 2022 after winning recognition at the IGNITION Global Solana Hackathon, the protocol has since expanded to multiple Solana Virtual Machine (SVM)-compatible chains. As of mid-2025, Invariant operates on Solana, Eclipse, and Sonic SVM, with prior deployments on Aleph Zero.

Core Mechanism

Invariant's central design is its Concentrated Liquidity Market Maker (CLMM), implemented natively in Rust using the Anchor framework. Rather than distributing liquidity uniformly across all price ranges, liquidity providers (LPs) specify discrete price intervals where their capital is active. When the market price stays within the selected range, that position earns trading fees.

Price ranges are expressed using "ticks," where each tick represents a 0.01% price step. This tick system allows LPs to target very narrow bands around the current price, generating significantly higher virtual liquidity from the same capital. According to the protocol's documentation, this design can make capital up to 40,000 times more efficient compared to a traditional constant-product AMM, depending on the range chosen.

Key Features

Customizable fee tiers and tick spacing. Pool creators choose fee tiers suited to the volatility profile of a given token pair, with the protocol fee set at 0.1 of swap fee revenue.

No NFT-based position management. Unlike some CLMM implementations that represent LP positions as non-fungible tokens, Invariant uses a simpler account-based position model.

Fully permissionless token listing. Any user can create a trading pool for any token pair without approval.

Concentrated farms. The protocol supports incentivized liquidity mining programs with transparent farm APY calculations.

Limit orders via AMM. Introduced in November 2022, allowing users to set target exit prices for positions.

AutoSwap. Automation for LP position rebalancing as price moves over time.

Multichain Expansion

Invariant's multichain strategy centers on SVM-based chains:

Eclipse was the second chain after Solana. Invariant became the most-used application on Eclipse, recording over 530,000 transactions in a single month and attracting over 300,000 users and $500 million in cumulative trading volume within the first six months. Peak TVL reached $10 million.

Sonic SVM, a super-fast SVM Layer 2 on Solana with gaming focus, became the third SVM chain deployment in June 2025.

Aleph Zero was an earlier non-SVM expansion (built using ink!/Rust), where Invariant received an Aleph Zero Ecosystem Funding Program grant in August 2023.

Performance and Metrics

As of mid-2025 per DeFiLlama, Invariant's TVL across chains was approximately $233,000, with Eclipse accounting for roughly 90%. Cumulative all-time trading volume has reached approximately $861 million. The USDC/USDT pool on Solana has historically returned around 29.5% APY to LPs.

Token

Invariant launched its native token INVT via a Token Generation Event on July 19, 2025. INVT serves as a governance and utility token: holders can participate in protocol governance, earn liquidity mining rewards as an LP incentive, and are positioned for potential collateral use across Solana DeFi.

Security

DeFiLlama's protocol profile for Invariant notes confirmed security audits. The smart contracts are implemented in Rust using the Anchor framework. The protocol has maintained no major outages since its March 2022 mainnet launch.

Team

Invariant was built by Mateusz Zając and Wojciech Cichocki, as credited on the protocol's Devpost hackathon submission for the IGNITION Global Solana Hackathon.

Solana Ecosystem Fit

Invariant was among the earliest protocols to bring Uniswap v3-style concentrated liquidity to Solana, at a time when the chain's DEX landscape was dominated by simpler constant-product AMMs. Its native Rust implementation takes advantage of Solana's low transaction costs and high throughput — both prerequisites for a CLMM to be practically usable. By expanding primarily to other SVM chains, Invariant has positioned itself as an infrastructure-layer liquidity provider for the broader SVM ecosystem.
