DEX-aggregator 1inch unveiled the second version of the protocol for limit-order operations — 1inch Limit Order Protocol v2. Users have access to ‘gasless’ swaps of permits-enabled tokens, ForkLog representatives said.
In June 2021, the limit-order protocol in the 1inch app launched. According to Dune Analytics, since then the feature has been used by more than 20,000 addresses, which executed about 60,000 trades with a total volume of $2.96 billion.
The new version of the protocol enables gasless swaps of tokens for ETH. This allows users who do not hold ETH in their balance to interact with the aggregator.
The service is available for permits-enabled tokens. This feature, proposed in EIP-2612, allows paying transaction fees using ERC-20 assets with the tokens themselves, rather than ETH.
On the Ethereum network, permits support 112 assets. A similar feature exists on Binance Smart Chain and Polygon networks. In the former, 33 projects are compatible; in the latter, 15. These include tokens like Aave (AAVE), Uniswap (UNI) and Balancer (BAL).
The developers also optimised the RFQ trading mode. For example, market makers can designate a specific тейкера for executing an order.
The audit of 1inch Limit Order Protocol v2 was conducted by several firms, including Certik and Pessimistic. The source code of the protocol is hosted in the GitHub repository GitHub.
Back in November, 1inch unveiled the fourth version of the protocol for a DEX liquidity aggregator.
