Funded escrow streams.
Real USDC movement.

StreamPay Level 4 upgrades the earlier stream tracker into a USDC-backed Soroban product with fee vault accounting, escrow withdrawals, and a stronger production path.

Multi-wallet USDC setup

StellarWalletsKit opens the wallet popup directly, so StreamPay can connect through supported Stellar wallets and guide users into testnet USDC trustline setup.

Real USDC escrow streams

Funded streams now lock testnet USDC into Soroban escrow, route protocol fees into FeeVault, and expose withdrawable balances over time.

Linked contract events

The dashboard tracks escrow and FeeVault events together, so funding, fee recording, withdrawals, and completions stay visible in one flow.

How it works

Three steps to a
funded Soroban stream.

  1. 01
    Connect from the wallet popup

    Open the StellarWalletsKit modal, choose a supported wallet, and continue only on Stellar Testnet with a test USDC trustline.

  2. 02
    Fund the escrow stream

    Set recipient, total amount, flow rate, and note. The app signs a Soroban transaction that moves USDC into StreamPay escrow and records the fee vault side effect.

  3. 03
    Withdraw and monitor

    Track claimable balance, withdrawals, fee events, and lifecycle changes directly from the StreamPay dashboard.
