The one-stop liquidity-as-a-service DeFi protocol iZUMi Finance announced at the InfraCon event in Seoul that it will launch the "Zero Gas Fee Transaction" service, which will be carried out in two stages. In the first phase, iZUMi Finance will issue semi-fungible tokens (SFT) to certified users, who will be eligible to receive iZi token airdrops to subsidize Gas Fee expenditures. Cheems, the meme token of the zkSync Era network, will be the partner and the first pilot in this phase. In the second phase of the "Zero Gas Fee Transaction" service, iZUMi Finance will cooperate with two service providers, Particle Network and Biconomy, which provide Account Abstraction (Account Abstraction) middleware for blockchain projects. It is Paymaster's smart contract model, which supports blockchain projects to automatically subsidize users for zero Gas Fee transactions.
