Scallop (SCA), a next-generation peer-to-peer money market built on the Sui blockchain, once stood as the flagship DeFi protocol in the ecosystem. Yet its native token has fallen more than 98% from its all-time high of $1.49. This article provides an in-depth look at the protocol's design, tokenomics, development journey, and current market reality.
What Is Scallop?
Scallop is a DeFi protocol that offers high-yield lending, low-fee borrowing, Automated Market Making (AMM), and digital asset self-custody tools. It was among the first DeFi projects to receive an official grant from the Sui Foundation in November 2022, highlighting its institutional-grade ambition. The native SCA token has a maximum supply of 250 million, with 45% allocated to liquidity mining, 15% to contributors, and the remainder to development, operations, strategic partners, advisors, and ecosystem growth. The release schedule is designed to support long-term liquidity, with varying lock-up periods.
How Does the Protocol Work?
Scallop functions as a peer-to-peer money market where users can lend and borrow directly. It integrates AMM tools for seamless trading and provides a Software Development Kit (SDK) for professional traders to execute complex strategies, including zero-interest loans. The protocol also features mixed asset pools, isolated pools, and flash loans. Security is prioritized through regular audits and a bug bounty program.
Key Milestones
Scallop won first place at the Sui Builder House Seoul Hackathon in June 2023 and the Move Hackathon by WebX Circle in July 2023. Its mainnet launched on Sui in July 2023, quickly reaching a peak Total Value Locked (TVL) of $156 million, making it the top DeFi protocol on Sui by lending and borrowing volume. In Q1 2024, Scallop raised $3 million in a strategic round co-led by CMS Holdings and 6th Man Ventures, and simultaneously launched the SCA token.
Tokenomics and Utility
SCA serves as both a governance and utility token. Holders can stake SCA to obtain veSCA, which grants voting rights and enhanced earning potential. As of May 25, 2026, the circulating supply stands at approximately 157.7 million SCA (63% of max supply).
How to Earn on Scallop
Users can earn by staking SCA with lock-up periods from 2 days to 4 years, or by lending assets on the platform to earn interest. The protocol also ran a two-phase airdrop campaign rewarding early supporters and active lenders/borrowers.
Market Performance and Risks
SCA reached an all-time high of $1.49 but has since declined by 98.66%. It sits approximately 31.77% above its all-time low of $0.02. Such volatility is common among DeFi tokens, driven by market sentiment, competition, and token unlocks. While Scallop remains a leading protocol on Sui, investors should conduct thorough DYOR and assess risks carefully.
