Sablier (sablier)

Token streaming protocol for continuous payments. Supports linear, cliff, and dynamic vesting schedules with NFT-based stream ownership.

What it offers

withdrawFromStream: Withdraw accrued tokens from an active stream
cancelStream: Cancel a stream and return remaining tokens to sender
createWithDurations: Create a new linear stream with cliff and total duration

Streams are ERC-721 NFTs - the stream recipient is the NFT owner
cliff: no tokens vest until cliff duration passes, then cliff amount vests immediately
Tokens accrue linearly between cliff and total duration
Only cancelable streams can be cancelled; non-cancelable streams run to completion
Approve the streaming asset to lockupLinear before createWithDurations
amount in withdraw is uint128, not uint256

On Ethereum, Sablier is a namespace: its contracts need no import.

function main() {
  // Ethereum's lockupLinear, `0xAFb979d9afAd1aD27C5eFf4E27226E3AB9e5dCC9`.
  require(Sablier.LockupLinear != 0);
}

createWithDurations((address sender, address recipient, uint128 totalAmount, address asset, bool cancelable, bool transferable, (uint40 cliff, uint40 total) durations, (address account, uint256 fee) broker) params) returns (uint256 streamId)
withdraw(uint256 streamId, address to, uint128 amount)
cancel(uint256 streamId)
