Introduction

‍

Decentralized finance is evolving beyond simple token swaps and into full-fledged financial ecosystems. Scallop is one of the leaders in this evolution, offering a secure, scalable, and institution-ready lending protocol built on the Sui blockchain. Whether you're a passive lender, an active borrower, or a DeFi builder, Scallop creates the tools and infrastructure to help you succeed.

‍

In this article, we will break down what Scallop is, how it works, and how to get involved using Backpack.

‍

‍

What is Scallop?

‍

Scallop is the first DeFi protocol officially backed by the Sui Foundation, making it a key player in the growth of the Sui ecosystem. Launched in 2021 by Kris Lai, the platform delivers a robust decentralized money market that includes lending/borrowing, flash loans, a trader-friendly SDK, and unique token mechanics. 

‍

Designed to be transparent and composable, Scallop allows users to interact directly with smart contracts without intermediaries or custodians.

‍

Key elements of the protocol include:

‍

• Lending & Borrowing Pools: Supply or borrow assets to earn interest and incentives.

• sCoins: Interest-bearing tokens representing deposits.

• Flash Loans: Collateral-free loans that must be repaid within a single transaction.

• Vote-Escrow Governance: Lock up $SCA tokens for voting power and rewards.

‍

‍

Funding and Backing

‍

Scallop was the first DeFi protocol to receive a grant from the Sui Foundation, underscoring its importance as a foundational pillar of the Sui ecosystem. In Q1 2024, it raised $3 million in a strategic investment round co-led by CMS Holdings and 6th Man Ventures.

‍

The round drew participation from a strong lineup of backers—including KuCoin Labs, Mysten Labs, and Blockchain Founders Fund—reflecting broad conviction in Scallop’s vision to become the leading lending protocol on Sui.

Key Features and Benefits

‍

• Lending & Borrowing: Earn interest by supplying assets or borrow by using crypto as collateral. Scallop supports flexible withdrawals and real-time interest accrual.
  
  
• sCoins: Tokenized proof of deposits (like sSUI for SUI), which grow in value over time due to accumulated interest.
  
  
• Flash Loans: Borrow large sums with no collateral as long as you repay within one transaction—ideal for arbitrage and DeFi strategies.
  
  
• SDK: Scallop offers open-source SDK for developers to build innovative DeFi products and solutions on top of Scallop.
  
  
• Vote-Escrow Model: Lock $SCA tokens to participate in governance and earn rewards, promoting long-term commitment.
  
  
• Composability: Scallop smart contracts are fully autonomous, permissionless, and integrate seamlessly with other Sui dApps.

Scallop Incentive Programs and Airdrops  

‍

Scallop’s incentive structure is anchored by veSCA, the vote-escrowed version of its native token $SCA. By locking SCA, users gain access to a suite of yield-boosting features and exclusive benefits across the protocol.

‍

Borrowing Incentives — Up to 4x APR Boost

‍

Users who lock SCA to mint veSCA can receive up to a 4x boost on their Borrow Reward APR. The multiplier is determined by the proportion of veSCA a user holds relative to their borrowing amount, measured against the total protocol activity.

‍

For example, if the base APR is 25%, users with the maximum boost receive 100% APR in SCA rewards.

‍

Referral Program — Earn from Borrow Fees

‍

Scallop’s referral program rewards users who lock SCA for veSCA by allowing them to earn a portion of the borrow fees generated by their referees. The more veSCA a referrer holds, the greater their reward.

‍

Referrers can earn up to 40% of their referees’ borrow fees, while referees can receive up to a 20% discount, making it a mutually beneficial system that strengthens long-term engagement.

‍

Loyalty Program — sSCA Rewards at Milestones

‍

Scallop’s Loyalty Program rewards veSCA holders whenever the protocol reaches specific revenue milestones. At each milestone, Scallop conducts a token buyback and redistributes those tokens to veSCA holders.

‍

The more veSCA a user holds, the greater their share of the reward pool. This mechanism aligns long-term participation with protocol growth and ensures that active contributors benefit directly from Scallop’s success.
