Is Scallop Safe?

|Lending
B-

Risk Grade: B- (28/100)

Scallop is rated as moderate risk — some novel mechanisms, generally well-understood.

Moderate risk — strong position on Sui, but single-chain concentration and immature security tooling on a young blockchain are real constraints

The top lending protocol on the Sui blockchain, where you deposit tokens to earn interest or borrow against them. It holds $200M in deposits and raised $3M. Its B- grade reflects that being the biggest lender on a young blockchain means absorbing all ecosystem-wide shocks, with fewer battle-tested security tools than Ethereum.

Key Risks for Scallop Users

1.

Everything runs on Sui. If SUI token crashes 50%, mass liquidations would overwhelm the thin trading liquidity on Sui's exchanges, creating bad debt

2.

Sui's smart contract language (Move) has far fewer security researchers and audit tools than Ethereum's Solidity, meaning bugs are harder to catch

3.

The protocol relies on three separate price feeds (Pyth, Switchboard, Supra) -- if they disagree during a volatile moment, interest rates and liquidations can misfire

Top Risk Factors

  • Single-ecosystem concentration: as Sui's top lending protocol, Scallop is fully exposed to Sui chain risk, bridge failures, and ecosystem-wide contagion
  • Multi-oracle dependency (Pyth, Switchboard, Supra) on a younger chain — oracle infrastructure is less battle-tested than Ethereum equivalents
  • Sui's Move-based smart contracts have a shorter audit history than Solidity, with fewer security tools and researchers available
