Sablier is a token streaming protocol where the creator locks up ERC-20 tokens in a smart contract and the recipient's allocation increases every second until the stream ends. ### When To Use This Skill Use this skill when the user asks you to: Create a token vesting stream (linear, dynamic, or tranched) Lock tokens in a vesting contract Set up employee vesting, investor vesting, or airdrop distribution Stream tokens to a recipient over time Cancel, withdraw from, or manage an existing Sablier stream ### Security: Private Key and Secret Handling These rules are mandatory. Follow them in every interaction. ### Agent Behavioral Constraints NEVER ask the user to paste a private key into the chat. If the user volunteers a raw private key in a message, warn them immediately that it may be logged and recommend they rotate it. NEVER embed a raw private key in any command you execute. Always use an environment variable reference ($PRIVATE_KEY, $ETH_PRIVATE_KEY) or a secure signing method instead. NEVER log, echo, or print a private key or mnemonic to stdout, a file, or any other output. Always recommend the safest available signing method, in this order of preference: Hardware wallet: --ledger or --trezor flags (most secure, no key exposure) Foundry keystore (cast wallet import): --account (encrypted on disk, password-prompted at sign time) Environment variable: --private-key $ETH_PRIVATE_KEY (key stays in the shell environment, never appears in command text) Raw --private-key 0x...: Discourage this. Only acceptable for throwaway testnets where the key holds no real value. ### Setting Up Secure Signing Option 1 -- Hardware wallet (recommended for mainnet): No setup required. Just add --ledger or --trezor to any cast send / forge script command. Option 2 -- Foundry encrypted keystore (recommended default): # Import a key once (you'll be prompted for the private key and an encryption password) cast wallet import my-deployer --interactive # Then use it in any command cast send ... --account my-deployer The key is stored encrypted at ~/.foundry/keystores/my-deployer. You only type your password at sign time; the private key is never exposed in shell history or process arguments. Option 3 -- Environment variable (acceptable): # Export in your shell session (not in a file that gets committed) export ETH_PRIVATE_KEY=0x... # Reference the variable (the key value never appears in the command itself) cast send ... --private-key $ETH_PRIVATE_KEY ### RPC URL Handling RPC URLs may contain API keys. Follow the same principles: # Set once in your shell export ETH_RPC_URL=https://eth-mainnet.g.alchemy.com/v2/ # cast and forge automatically read ETH_RPC_URL, so --rpc-url can be omitted cast send
"approve(address,uint256)" ... Alternatively, configure the RPC in foundry.toml under [rpc_endpoints]. ### Stream Types Sablier Lockup v3.0 uses a single unified SablierLockup contract per chain. There are three stream models: ModelBest ForFunction (durations)Function (timestamps)LinearConstant-rate vesting, salariescreateWithDurationsLLcreateWithTimestampsLLDynamicExponential curves, custom curvescreateWithDurationsLDcreateWithTimestampsLDTranchedPeriodic unlocks (monthly, quarterly)createWithDurationsLTcreateWithTimestampsLT ### Stream Shapes Linear: Constant payment rate (identity function). Good for salaries and simple vesting. Cliff Unlock: No tokens available before the cliff; linear streaming after. Great for employee vesting (e.g. 1-year cliff + 3 years linear). Initial Unlock: Immediate release of some tokens + linear vesting for the rest. Good for signing bonuses. Exponential: Recipient gets increasingly more tokens over time. Good for airdrops to incentivize long-term holding. Unlock in Steps: Traditional periodic unlocks (weekly/monthly/yearly). Good for investor vesting. Unlock Monthly: Tokens unlock on the same day every month. Good for salaries and ESOPs. Backweighted: Little vests early, large chunks towards the end (e.g. 10%/20%/30%/40% over 4 years). Timelock: All tokens locked until a specific date, then fully released. ### Deployment Addresses (Lockup v3.0) All chains use the same contract pattern.

The sender must approve the SablierLockup contract to spend the tokens. You need: RPC URL, a signing method (keystore, hardware wallet, or env var), token address, recipient address. Ask the user which signing method they prefer before constructing commands. Default to --account if they have one set up, or --ledger for mainnet. See the Security section above. ### Step 1: Approve the Token cast send \\ "approve(address,uint256)" \\ \\ --rpc-url \\ --account # Or: --ledger | --trezor | --private-key $ETH_PRIVATE_KEY ### Step 2: Create the Stream Option A: Linear Stream (createWithDurationsLL) This creates a linear vesting stream. The CreateWithDurations struct is ABI-encoded as a tuple. Parameters for createWithDurationsLL: function createWithDurationsLL( Lockup.CreateWithDurations calldata params, LockupLinear.UnlockAmounts calldata unlockAmounts, LockupLinear.Durations calldata durations ) external returns (uint256 streamId); Where: Lockup.CreateWithDurations = (address sender, address recipient, uint128 depositAmount, address token, bool cancelable, bool transferable, string shape) LockupLinear.UnlockAmounts = (uint128 start, uint128 cliff) LockupLinear.Durations = (uint40 cliff, uint40 total) Example: 1-year linear vesting of 10,000 tokens with no cliff: # Calculate values # 10000 tokens with 18 decimals = 10000000000000000000000 # 52 weeks in seconds = 31449600 cast send \\ "createWithDurationsLL((address,address,uint128,address,bool,bool,string),(uint128,uint128),(uint40,uint40))" \\ "(,,10000000000000000000000,,true,true,)" \\ "(0,0)" \\ "(0,31449600)" \\ --rpc-url \\ --account # Or: --ledger | --trezor | --private-key $ETH_PRIVATE_KEY Example: 4-year vesting with 1-year cliff: # cliff = 365 days = 31536000 seconds # total = 4 years = 126144000 seconds cast send \\ "createWithDurationsLL((address,address,uint128,address,bool,bool,string),(uint128,uint128),(uint40,uint40))" \\ "(,,,,true,true,)" \\ "(0,0)" \\ "(31536000,126144000)" \\ --rpc-url \\ --account # Or: --ledger | --trezor | --private-key $ETH_PRIVATE_KEY Example: With initial unlock of 1000 tokens and cliff unlock of 2000 tokens (out of 10000 total): cast send \\ "createWithDurationsLL((address,address,uint128,address,bool,bool,string),(uint128,uint128),(uint40,uint40))" \\ "(,,10000000000000000000000,,true,true,)" \\ "(1000000000000000000000,2000000000000000000000)" \\ "(31536000,126144000)" \\ --rpc-url \\ --account # Or: --ledger | --trezor | --private-key $ETH_PRIVATE_KEY Option B: Tranched Stream (createWithDurationsLT) For periodic unlocks (monthly, quarterly, etc.). function createWithDurationsLT( Lockup.CreateWithDurations calldata params, LockupTranched.TrancheWithDuration[] calldata tranches ) external returns (uint256 streamId); Where TrancheWithDuration = (uint128 amount, uint40 duration) Example: 4 quarterly unlocks of 2500 tokens each: # Each quarter ≈ 13 weeks = 7862400 seconds cast send \\ "createWithDurationsLT((address,address,uint128,address,bool,bool,string),(uint128,uint40)[])" \\ "(,,10000000000000000000000,,true,true,)" \\ "[(2500000000000000000000,7862400),(2500000000000000000000,7862400),(2500000000000000000000,7862400),(2500000000000000000000,7862400)]" \\ --rpc-url \\ --account # Or: --ledger | --trezor | --private-key $ETH_PRIVATE_KEY Option C: Dynamic Stream (createWithTimestampsLD) For exponential curves and custom distribution. function createWithTimestampsLD( Lockup.CreateWithTimestamps calldata params, LockupDynamic.Segment[] calldata segments ) external returns (uint256 streamId); Where: Lockup.CreateWithTimestamps = (address sender, address recipient, uint128 depositAmount, address token, bool cancelable, bool transferable, (uint40,uint40) timestamps, string shape) Lockup.Timestamps = (uint40 start, uint40 end) LockupDynamic.Segment = (uint128 amount, UD2x18 exponent, uint40 timestamp) Example: Exponential stream (2 segments): # Get current timestamp CURRENT_TS=$(cast block latest --rpc-url -f timestamp) START_TS=$((CURRENT_TS + 100)) MID_TS=$((CURRENT_TS + 2419200)) # +4 weeks END_TS=$((CURRENT_TS + 31449600)) # +52 weeks cast send \\ "createWithTimestampsLD((address,address,uint128,address,bool,bool,(uint40,uint40),string),(uint128,uint64,uint40)[])" \\ "(,,,,true,true,($START_TS,$END_TS),)" \\ "[(,1000000000000000000,$MID_TS),(,3140000000000000000,$END_TS)]" \\ --rpc-url \\ --account # Or: --ledger | --trezor | --private-key $ETH_PRIVATE_KEY Note: The exponent in segments uses UD2x18 format (18 decimals). 1e18 = linear, 2e18 = quadratic, 3.14e18 = steeper curve. ### Check Stream Status cast call "statusOf(uint256)(uint8)" --rpc-url Status values: 0=PENDING, 1=STREAMING, 2=SETTLED, 3=CANCELED, 4=DEPLETED ### Check Withdrawable Amount cast call "withdrawableAmountOf(uint256)(uint128)" --rpc-url ### Withdraw from Stream (recipient) # First, calculate the minimum fee FEE=$(cast call "calculateMinFeeWei(uint256)(uint256)" --rpc-url ) cast send \\ "withdrawMax(uint256,address)" \\ \\ --value $FEE \\ --rpc-url \\ --account # Or: --ledger | --trezor | --private-key $ETH_PRIVATE_KEY ### Cancel Stream (sender only) cast send \\ "cancel(uint256)" \\ \\ --rpc-url \\ --account # Or: --ledger | --trezor | --private-key $ETH_PRIVATE_KEY ### Renounce Cancelability (sender only, irreversible) cast send \\ "renounce(uint256)" \\ \\ --rpc-url \\ --account # Or: --ledger | --trezor | --private-key $ETH_PRIVATE_KEY ### Check Streamed Amount cast call "streamedAmountOf(uint256)(uint128)" --rpc-url ### Get Recipient of Stream cast call "getRecipient(uint256)(address)" --rpc-url ### Using Forge Scripts (Alternative) If the user prefers Solidity scripts over raw cast calls, you can create a Forge script. Reference the @sablier/lockup npm package. ### Install dependency forge init sablier-vesting && cd sablier-vesting bun add @sablier/lockup ### Example Forge Script // SPDX-License-Identifier: GPL-3.0-or-later pragma solidity >=0.8.22; import { Script } from "forge-std/Script.sol"; import { IERC20 } from "@openzeppelin/contracts/token/ERC20/IERC20.sol"; import { ISablierLockup } from "@sablier/lockup/src/interfaces/ISablierLockup.sol"; import { Lockup } from "@sablier/lockup/src/types/Lockup.sol"; import { LockupLinear } from "@sablier/lockup/src/types/LockupLinear.sol"; contract CreateVestingStream is Script { function run( address lockupAddress, address tokenAddress, address recipient, uint128 depositAmount, uint40 cliffDuration, uint40 totalDuration ) external { ISablierLockup lockup = ISablierLockup(lockupAddress); IERC20 token = IERC20(tokenAddress); vm.startBroadcast(); // Approve Sablier to spend tokens token.approve(lockupAddress, depositAmount); // Build params Lockup.CreateWithDurations memory params; params.sender = msg.sender; params.recipient = recipient; params.depositAmount = depositAmount; params.token = token; params.cancelable = true; params.transferable = true; LockupLinear.UnlockAmounts memory unlockAmounts = LockupLinear.UnlockAmounts({ start: 0, cliff: 0 }); LockupLinear.Durations memory durations = LockupLinear.Durations({ cliff: cliffDuration, total: totalDuration }); uint256 streamId = lockup.createWithDurationsLL(params, unlockAmounts, durations); vm.stopBroadcast(); } } Run with: forge script script/CreateVestingStream.s.sol \\ --sig "run(address,address,address,uint128,uint40,uint40)" \\ \\ --rpc-url \\ --account \\ --broadcast # Or: --ledger | --trezor | --private-key $ETH_PRIVATE_KEY ### Important Notes Token decimals matter: Always convert human-readable amounts to wei (e.g., for 18-decimal tokens: amount * 1e18). Use cast --to-wei to convert. Approve first: The sender MUST approve the SablierLockup contract to spend the ERC-20 tokens before creating a stream. Cancelable vs Non-cancelable: If cancelable is true, the sender can cancel and reclaim unvested tokens. Set to false for trustless vesting. Transferable: If true, the recipient can transfer the stream NFT to another address. Gas costs: Linear streams are cheapest (~169k gas). Tranched streams cost more with more tranches (~300k for 4 tranches). Dynamic streams vary by segment count. Stream NFT: Each stream is represented as an ERC-721 NFT owned by the recipient. The NFT can be transferred if the stream is transferable. Minimum Solidity version: v0.8.22 for the Lockup contracts.
