Audits & Exploits

• Stargate does not offer a bug bounty (14-4-2022).
• Scored 60% on DeFi Safety (14-4-2022):

"This protocol documents no tests for code coverage. Nevertheless, with 181% TtC we can assume there is good testing on Stargate. There is no test report documented by Stargate. Stargate has not undergone formal verification. Stargate was audited twice before launch and once after. Stargate does not offer a bug bounty at time of writing."

How it works

• From this bridge blog (21-4-2022):

"Most existing bridges can not send native tokens from one chain to another and rely on intermediate or ‘wrapped’ tokens to complete the bridging process. This approach creates a user experience that is slow and highly inefficient. Stargate is built around unified liquidity pools shared among many chains, ensuring that there is always adequate liquidity available and fast finality. The ultimate goal is to make cross-chain bridging seamless through a single transaction.

How Stargate solves the Bridging Trilemma:

1. Instant Guaranteed Finality. Stargate assures users and dApps that any transfer requests they make on the source chain will arrive to the destination chain. However, liquidity must be there on the destination chain, or transactions will be reverted. With Stargate’s bridge, there is no need to wrap tokens and users won’t need to swap the tokens manually on the receiving chain.
2. Cross-Chain Composability. The Stargate bridge can be composed of smart contracts from both the origin and destination chains. This will allow users to complete several swaps in a single cross-chain transaction. Imagine swapping $wBTC on Fantom for $JOE on Avalanche and entering an LP position in a single transaction without leaving Fantom.
3. Unified Liquidity. Most existing bridges require fragmentation of liquidity to function. Each chain integrated into the bridge needs a designated liquidity pool for each asset bridged. Users can also experience long delays or failed transactions if insufficient liquidity is available. A bridge that wants to add a new blockchain must also bootstrap a new pool to accommodate the new chain with sufficient liquidity on each existing chain.

Stargate presents a unified approach where all connections deposit and withdraw from a single liquidity pool, allowing Stargate to achieve scalability and efficiency that’s not possible on the lock-and-mint or burn-and-redeem bridges. Stargate also has efficient rebalancing and self-limiting mechanisms to manage spikes in withdrawal activity. Each chain on the protocol can maintain a single pool of liquidity that is “soft-partitioned” into different slices, where every slice corresponds to a specific chain in the network."

Interoperability

• Connected to Arbitrum, Avalanche, BSC, Ethereum, Fantom, Polygon and Optimism according to DeFi Safety (14-4-2022).

Oracle Method

• From DeFi Safety (14-4-2022):

"Stargate's data source is not documented. The contracts dependent are not identified. There is no relevant software function documentation. Stargate is a bridge, and is therefore is not susceptible to front-running. Stargate provides guaranteed instant finality, meaning that whatever amount of funds you bridge will be equivalently minted on the other side. Stargate documents no flash loan exploit countermeasures."
