Security

As a reminder, Swaap v2 relies on 3 core modules, as described in the graphics below

The protocol’s security is paramount to us. We want our users’ funds to be as safe as possible.

In order to achieve that, each module has gone through extensive security checks.

Inventory This module, which takes care of the asset accounting and execution (join pool, exit pool, swap assets) is a fork of Balancer V2 Vault infrastructure. It therefore inherits from its benefits and security guarantees.

Balancer v2 has been live for 2 years with up to $1bn in TVL secured. The protocol has been thoughtfully audited by Trail of Bits, Consensys Diligence and OpenZeppelin.

Quotation This module provides the quote at which traders can execute transactions. It is a proprietary offchain module.

It has been stress tested using the AMM simulator, a tool developed by Swaap Labs in collaboration with the Louis Bachelier Institute. For more information about it, refer to this paper.

Safety on this module is delivered by the Settlement module, whose role is to perform onchain authenticity and performance checks on the quotes provided.

Settlement Prior to executing a trade, the Settlement module employs on-chain safeguards to revise or reject outdated or underpriced quotes. These include a Max Drawdown Circuit Breaker, Last Look, and Max Imbalance. These safeguards are designed to protect LPs' funds, especially during extreme market conditions such as flash crashes or stablecoin de-peggings. For more information, please refer to the v2 whitepaper.

The settlement module has been carefully audited by two prestigious & independent security firms:

Control and Upgradability​

The core smart contracts of Swaap, such as the Vault, the SafeguardPool, and the SafeguardFactory, are designed to be immutable for enhanced security. This means they cannot be upgraded or modified.

However, certain parameters can be controlled by the DAO through a multisig mechanism. These allow the DAO to perform actions like pausing or unpausing the contracts and adjusting certain safeguard parameters. However, it's crucial to understand that these parameters and actions do not grant the Swaap team any access to liquidity providers' deposits. Moreover, they don't influence the pricing of the pool. Their main function is to set loss limits and implement safeguards against extreme unforeseen events. Notably, the Swaap team has the ability to pause the protocol within the first 9 months following the deployment of its contracts.

Moreover, the DAO has the capability to initiate fee collection based on the pool's total supply. While these fees have a yearly cap of 5%, they are presently inactive as of 10/10/2023.

This approach ensures transparency and reinforces our commitment to safeguarding users' assets. For detailed information on available actions, please refer to the Governance and Safeguard Pool sections.

Recommendations​

By design, Swaap pools can be minted in a permissionless way, therefore anyone can create their own pool. Before providing liquidity to any of them, we advise you to run the following checks to prevent any loss of funds:

  • Ensure that the pool has been deployed with Swaap’s Factory.
  • Check the address of the tokens of the pool you are joining and check that they are correctly implementing ERC20’s standard.
  • Ensure that the tokens within the pool are all distinct. Pools with the same token twice are not supported by the protocol. For instance, you should not join an ETH / ETH / DAI pool. P.S. in rare cases, different token addresses can point to the same token balance. These tokens are not supported by the Swaap pool and must be avoided as well.
  • Ensure that the right Chainlink oracles are associated with the right tokens (refer to Chainlink's documentation).

The pools that are available on the Swaap frontend have all been carefully vetted by the Swaap Labs team, so there is no need to run such verifications on them.

Disclaimer​

Please note that while Swaap v2 has undergone extensive security checks and auditing, no system can be completely secure. As with all smart contract-based platforms, there exists an inherent risk when interacting with contracts. Smart contracts are permanent on the blockchain; once deployed, they cannot be altered. This can be advantageous for trust and security, but if there is an error or vulnerability in the code, it might be exploited.

Users should exercise caution and conduct their own research before interacting with Swaap or any other DeFi protocols. It is important to have a clear understanding of the smart contract interactions, the associated risks, and to use the platform at your own risk.

Swaap is not responsible for any losses incurred due to the use or interaction with its smart contracts, and users are encouraged to only invest funds they can afford to lose. It is highly recommended to stay informed and be vigilant of the changing dynamics in the DeFi space.
