PANews reported on May 30 that according to The Block, Bitcoin Lightning Network service provider Amboss launched a self-custodial income product Rails, allowing users to earn income by providing liquidity. The product includes two plans: Rails LP is for enterprises and high-net-worth users (minimum 1BTC locked for 1 year), and the liquidity subscription service is suitable for Bitcoin payment merchants (rate starting at 0.5%). The sources of income include payment routing and liquidity leasing, but there is no guaranteed return.
