NEAR Rainbow Bridge Great Leap Forward-an early adopter of the trend of public chain bridging

NEAR officially released the Ethereum cross-chain rainbow bridge, which is currently running between the NEAR testnet and the Ethereum Ropsten Testnet, without sacrificing the trustless and permissionless features of the blockchain. Rainbow Bridge can do:

  • Bridging homogeneous tokens, non-homogeneous tokens or any kind of assets
  • Write an Ethereum contract that uses contract status or NEAR verification nodes
  • Use Rainbow Bridge to make cross-contract calls

In the construction of the NEAR ecosystem, the decentralized prediction market platform Flux also released its mainnet, becoming the first Defi protocol released on the NEAR platform. The horse racing game ZEST is currently also running on the NEAR main network. The predecessor of the game was deployed on Ethereum. At the same time, the Ethereum NFT platform Mintbase has just begun to open up the NEAR mainnet.

It is reported that this is the first production ready fully decentralized bridge.

In terms of accelerating the construction of financial infrastructure, using Rainbow Bridge technology, anyone (user, app, developer or any entity) can transfer assets between Ethereum and NEAR without permission. Stable coins such as USDT or DAI will become the basis for more open finance and open network use cases. NEAR’s capacity expansion and low fees have greatly reduced the threshold for use. Therefore, more and more Ethereum projects are considering migrating to the NEAR platform.

Will the use of oracles be the ultimate killer of impermanence?

AMMs use mathematical formulas (ie algorithms, joint curves) to replace order matching, which determines the price based on the number of underlying assets in the pool and the number of trading assets between the pool.

In order to increase the depth of the liquidity pool, AMMs have been providing incentives such as “liquidity mining” to attract millions of dollars worth of assets into the pool. However, depositors quickly realized that providing AMM with liquidity may in some cases be inferior to simply putting assets in a wallet. This problem is also known as impermanent loss.

In more detail, AMMs rely on the continuous arbitrage of market participants to adjust the proportion of asset reserves in the liquidity pool, so that AMM prices are always consistent with external market prices. However, arbitrage profits come at the expense of liquidity providers. The loss will only be offset when the price returns to the initial ratio, which is why it is defined as non-permanent. However, due to the high volatility of encrypted assets, non-permanent losses sometimes become permanent losses.

Bancor simply explained the impermanence loss with the following figures. They compared the LP portfolio and the HODLer portfolio (HODL-hold for dear life, meaning to keep in the wallet). For simplicity, this example assumes that there are no transaction fees. When the relative price of coins changes, HODLer is more advantageous than LP due to the aforementioned arbitrage effect.

The solutions to impermanence losses at this stage can be divided into two categories:

Focus on assets with less volatility -> reduce the probability of impermanent losses

Since impermanence losses are closely related to asset volatility, the simplest solution is to ignore assets with high volatility. For example, Curve.fi focuses on stable currency transactions, which is why Curve’s liquidity providers rarely worry about impermanence losses. Only when a stable currency is decoupled, impermanence losses will occur.

Use oracles to get a “fairer” price

Bancor uses Chainlink oracles instead of relying on arbitrage to balance AMM prices with market prices. The weight of each asset in the pool will be adjusted according to the latest price of the oracle, while eliminating arbitrage opportunities and protecting the asset value of liquidity providers.

DODO has also adopted a similar solution. However, both DODO and Bancor v2 are still in the early stages, and it has not been proven that continuous reliance on oracles can truly solve the problem of impermanence. This scheme has risks such as the failure of the oracle and the arbitrage speed is faster than the price update speed. In this case, impermanence losses are still possible.
