Solidly exchange

Solidly exchange, a decentralized finance (DeFi) protocol designed for efficient stablecoin trading with a novel fee distribution model. Also known as Solidly finance, it was built as a fork of the popular Uniswap V2 code but introduced radical changes to how liquidity providers earn rewards. Unlike most DEXs that charge a flat 0.3% fee on trades, Solidly exchange lets liquidity providers capture 100% of trading fees from the pool they’re in—while also earning voting rewards for locking their tokens. This design turned it into a magnet for large stablecoin liquidity in 2021, especially on Polygon and Fantom.

What made Solidly exchange stand out wasn’t just its fee structure—it was its voting mechanism, a system where users lock their tokens to gain voting power and influence which trading pairs get fee rewards. If you locked Solidly’s native token for four years, you could vote to direct all trading fees toward specific pools like USDT/USDC or DAI/FRAX. This created a game where big players competed to lock up tokens and control the flow of revenue, not just to earn fees but to dominate the protocol’s direction. The result? A few wallets ended up controlling over 80% of the voting power, sparking debates about centralization in DeFi.

But here’s the twist: Solidly exchange didn’t survive its own success. In early 2022, its founder abruptly left and open-sourced the code, triggering a wave of forks. Projects like Velodrome, a popular fork on Optimism that improved user experience and added more flexible voting options, took the core idea and made it better. Others, like Solidity, a programming language used to write smart contracts on Ethereum, often confused with Solidly due to similar naming, have no relation at all—but people still mix them up. The original Solidly exchange faded, but its DNA lives on in dozens of DeFi protocols that now use its fee-incentive model to attract liquidity.

Today, if you’re looking at a DEX that gives you voting rights for locking tokens and lets you steer where trading fees go, you’re probably using a Solidly-style protocol. The original didn’t last, but its ideas reshaped how DeFi rewards liquidity. The posts below dive into real examples: what went wrong with the original, how forks like Velodrome fixed its flaws, and why some traders still avoid it entirely. You’ll also find reviews of exchanges that copied its model—and others that tried and failed. Whether you’re a liquidity provider or just curious about DeFi’s wild experiments, this collection shows how one flawed idea sparked a revolution.
