Range plans to transform IBC and the interchain into the most secure DeFi ecosystem, for which forming connections with Osmosis and Stride is on the anvil. Together they will develop risk tools, such as the IBC dashboard, and enhance the upcoming delivery of IBC rate limits v2. The idea of capitalizing on this is because it is the best decentralized service for improving the safety factors related to the inter-chain.
Bridges are the most vulnerable in crypto, responsible for more than $3 billion in losses. Many bridges provide large TVL and come with complicated codebases, which attracts the attention of fraudsters. Yet a large number of hacking incidents are attributed to software errors.
Sometime in 2022, the BSC Bridge experienced a $100 million transfer. This was attributed to a flaw in the IAVL Merkle-proof authentication mechanism that uses an unprovisioned Cosmos IBC library. Then Dragonberry’s weakness emerged, providing IBC with evidence of twice issuing assets to different chains.
In retaliation, Osmosis introduced IBC rate limits after the BSC and Dragonberry accident. IBC rate limits are the ceilings during idle times and calculate the net flow of an asset. This system stops moving large amounts of money, reducing the risk factor.
What differentiates rate caps from retrofit security factors is that they do not provide sufficient points of centralization within a protocol and blockchain.
Fee limits will be mandatory for blockchains that leverage economic functions and TVLs linked interchain, similar to the Wormhole Bridge.
IBC rate limits were initially created by Osmosis and will be positioned live in 2023. Within the Osmosis embodiment, the rate limit concept is implemented as a CosmWasm smart contract, which connects to an IBC middleware wrapper that includes the average ICS-20 transfer application.
