Streaming Payment Recipient Change Tool

WHAT IT DOES

Streaming Payment Recipient Change Tool is a DeFi-focused tool that enables senders to change the recipient of an active payment stream. Unlike static streams that lock in a single recipient, this tool allows the stream sender to redirect the remaining stream balance to a new recipient, useful for updating payment destinations or correcting errors. It reads stream status, verifies the current recipient, checks stream parameters (sender, total amount, start time, stop time), calculates remaining balance, and validates recipient change eligibility. The tool supports Ethereum, Polygon, Arbitrum, Optimism, Avalanche, BNB Chain, and Base, providing a unified interface to change stream recipients across multiple networks. This is essential for users who need to update payment destinations, such as when an employee leaves, a contractor changes wallets, or a payment needs to be redirected.

HOW TO USE

Connect your wallet using WalletConnect or a compatible browser extension. Ensure your wallet is on the network where the stream contract is deployed. Enter the stream contract address—this is the contract you are interacting with, and you are vouching for its safety. Enter the stream ID and the new recipient address. Click "Check stream" to verify the stream is active, confirm you are the sender, and ensure the new recipient is different from the current recipient. The tool displays the sender, current recipient, new recipient, remaining balance, and stream status. If the stream is active and the new recipient is valid, the "Change recipient" button appears. Click it to submit the recipient change transaction. The tool updates the stream's recipient to the new address, redirecting all future payments. The tool displays a transaction link to your chain's block explorer and logs the final gas cost using receipt.effectiveGasPrice.

ADAPTIVE RECIPIENT CHANGE VALIDATION AND EXECUTION ENGINE

The core technical mechanism that distinguishes this tool is its adaptive recipient change validation and execution engine. Unlike simple transfer tools that assume all conditions are met, this tool performs comprehensive validation before allowing a recipient change. The engine first reads the full stream data using getStream(streamId), extracting the sender, current recipient, start time, stop time, and total amount. It then checks the stream status using isActive(streamId), isCancelled(streamId), and isCompleted(streamId) to confirm the stream is in a state that supports recipient modification. The engine verifies that the connected wallet matches the stream sender, as only the sender can change the recipient. It also validates the new recipient address, ensuring it is a valid address and different from the current recipient. The engine calculates the remaining balance and displays it for reference. If all checks pass, the change is enabled. When executed, the tool calls the changeRecipient() function, which updates the stream's recipient address. All RPC calls are wrapped with timeout and retry logic, and the tool automatically falls back to a secondary provider if the primary endpoint fails or rate-limits, ensuring validation completes even during network congestion.

WHAT IT CANNOT SEE

The tool cannot guarantee that recipient changes will execute correctly if the stream is already completed or cancelled, the new recipient address is invalid, the stream contract does not support recipient modification, or the stream contract's logic changes before the change is confirmed. It has no visibility into the stream contract's internal recipient management logic beyond what the contract exposes, nor can it predict if the contract logic will be modified. The tool cannot detect if the stream contract has been upgraded. It does not monitor streams after recipient change—it is a change tool, not a tracking service. The tool cannot interact with non-EVM chains, private networks, or stream contracts that do not implement the standard recipient change interface it expects.

PLEASE NOTE

This tool is designed exclusively for EVM-compatible blockchain networks. It supports Ethereum, Polygon, Arbitrum, Optimism, Avalanche, BNB Chain, Base, and similar chains. Non-EVM networks such as Solana, Cosmos, or Bitcoin are not supported. Always verify the stream contract address, stream ID, and new recipient before changing—the tool does not validate contract safety or recipient change terms beyond basic verification. The tool provides estimates only—actual gas costs are determined at the time of transaction execution. Users are responsible for understanding recipient change risks, including the possibility that the contract may not handle recipient changes as expected.
