Wu said that Ethena and Securitize announced a collaboration to submit a USDtb stablecoin application to participate in SkyEcosystem's $1 billion tokenization grand prize, proposing to use BlackRock BUIDL as the main reserve asset to support USDtb. USDtb is the only stablecoin on the market that can be fully supported by BlackRock BUIDL. The proposal also plans to establish a swap mechanism for USDtb and USDe, allowing SkyEcosystem to achieve seamless redistribution between the two assets when adjusting its reserve asset configuration.
