Opcode: STREAMUPDATE

[PaulRBerg]

Spec

Updates the stream with the sender msg.sender and the recipient recipient for token with ID token_id by setting the payment rate to new_amount per new_cadence.

Input

• recipient of type `Address
• token_id of type U256
• new_amount of type U256
• new_cadence of type U16

Output

None.

Receipt

• New receipt of type StreamUpdate
• Data
  • The sender's updated terminus of type U256

Errors

• The update MUST NOT cause the sender to be either insolvent or have a solvency lower than 1 hour

Notes

• Can be executed either by an EOA via one of the new transaction types or by a contract
• I went with STREAMUPDATE instead of UPDATESTREAM so that all streaming-related opcodes can be grouped together
• The spec assumes that there can be only one stream between users
