Gasless payments (EIP-2612)

Built with

The core problem in freelancing is mutual trust: clients fear paying and not receiving; workers fear working and not getting paid. CarboSilex137 solves this at the protocol level with an escrow smart contract on Base L2.

How it works

1

Deposit

The client deposits USDC into the escrow contract. The funds are locked.

2

Lock

Neither the client nor the platform can move the locked funds.

3

Work

The assigned freelancer completes the job and submits a delivery.

4

Release

The client approves the delivery → USDC is released automatically to the freelancer.

5

Dispute

If there’s a disagreement, on-chain validators vote to release or refund.

What this guarantees

  • No chargebacks. Once funded, the worker is guaranteed payment on approval.
  • No “pay me later.” The money is already in the contract before work starts.
  • No platform custody risk. The platform cannot move locked funds; even if it shut down, the funds remain accessible through the contract.
  • Auditable. The contract is public on Basescan.
