This newsletter is made possible thanks to Sablier


Sablier V2 is a next-generation token streaming protocol that doubles down on our flagship Lockup design.

V2 pushes the boundaries of web3 payment protocols:

  • Non-linear streaming: exponentials, logarithms, or any other curve
  • Every stream is a transferable NFT
  • Third-party UIs can monetize their Sablier integration with broker fees
