Errors

Background​

Sablier employs the convenient and gas-efficient custom errors introduced in Solidity v0.8.4.

The error data encoding is identical to the ABI encoding used for function calls, e.g.:

abi.encodeWithSignature("SablierV2Lockup_Unauthorized(address,uint256)", streamId, msg.sender).

Naming Pattern​

With the exception of a few generics, all errors in Sablier V2 adhere to the naming pattern SablierV2<ContractName>_<ErrorName>.

Incorporating the contract name as a prefix offers context, making it easier for end users to pinpoint the contract responsible for a reverted transaction. This approach is particularly helpful for complex transactions involving multiple contracts.
