createEscrow

function createEscrow(
    address freelancer,
    uint256 amount,
    address token,
    uint256 durationInSeconds
) external returns (uint256)

Creates an unfunded escrow. The caller becomes the client.

Rules

• freelancer cannot be zero;
• amount must be greater than zero;
• token cannot be zero;
• durationInSeconds must be greater than zero.

Effects

The function increments nextEscrowId, calculates deadline = block.timestamp + durationInSeconds, stores the escrow with Created status, emits EscrowCreated, and returns the ID.

Reverts

• ZeroAddress()
• InvalidAmount()

Creating an escrow does not move tokens. The client must approve token spending and then call fundEscrow.
