FlowEDU

FlowEDU is a fully automated token bridge purpose-built for the EDU ecosystem. It transforms the typical multi-step, complex bridging process into a simple, one-click experience for users. By handling everything on the backend — from wallet management to gas funding and cross-chain execution — FlowEDU enables seamless asset transfers across chains like BNB Chain and Arbitrum.

Problem Statement

Bridging tokens today is tedious:

• Users must manually switch networks.

• They need native gas tokens on both chains.

• Many are confused by multiple transaction confirmations.

• Errors are easy; onboarding is hard.

FlowEDU solves this by abstracting away all complexity, allowing users to deposit tokens on one chain and receive them on another without worrying about the in-between steps.

Key Features

• ✦ Seamless Bridging with Single Interaction

• ✦ Automatic Gas Funding on Destination Chain

• ✦ Secure Cross-Chain Wallet Binding

• ✦ Fee Collection for Protocol Sustainability

• ✦ Real-Time Event Monitoring with Ponder

• ✦ Built on LayerZero OFT Standard for Secure Bridging

Bridging Flow — Step-by-step Breakdown

This flow describes how a user bridges EDU tokens from BNB Chain to Arbitrum using FlowEDU.

1. User sends EDU tokens to their FlowEDU-assigned wallet on BNB Chain.

• Every user gets a unique deposit address after binding.

2. Ponder detects the deposit event.

• Monitors ERC20 Transfer events on BNB Chain.

• Verifies that the receiving wallet is a bound FlowEDU address.

3. FlowEDU checks balance thresholds.

• If the EDU token balance in the wallet exceeds a set threshold, it proceeds.

• If the wallet lacks BNB for gas fees, FlowEDU automatically funds it from a central treasury.

4. FlowEDU sweeps tokens to a central account.

• Transfers all EDU from the user's wallet to a central FlowEDU-controlled wallet on BNB Chain.

5. Bridging via LayerZero.

• FlowEDU calls the sendFrom function on LayerZero's ProxyOFTV2 contract to bridge EDU tokens from BNB Chain to Arbitrum.

6. Tokens arrive on Arbitrum.

• FlowEDU receives the bridged tokens in its central wallet on Arbitrum.

7. Final payout to user.

• FlowEDU sends (Total Tokens - 0.3% Fee) to the user’s bound wallet on Arbitrum.

Wallet Binding Flow — Step-by-step Breakdown

This flow describes how FlowEDU securely links a user’s wallet across chains.

1. User connects their wallet on the source chain (BNB Chain).

2. Backend generates a new ED25519 key pair for the user.

• This key pair represents the user’s FlowEDU identity.

3. User signs a binding message.

• The signed message includes:

  • The generated public key

  • Current timestamp

  • A human-readable message clarifying intent ("I am binding my wallet to FlowEDU")

4. Backend verifies the signature.

• Ensures the message was signed by the connected wallet.

5. Wallet Binding is stored.

• The user’s EVM address → Public Key mapping is recorded.

• FlowEDU uses this to derive or link the user’s corresponding wallets on other chains.

Why this Matters

→ Users only need to interact once.
→ They don’t need to hold gas tokens on the destination chain.
→ They don’t need to know how bridges or LayerZero work.
→ Everything "just works" behind the scenes.
