Optimism

EVM settlement on Optimism through the Dexter facilitator.

Optimism is part of Dexter's production EVM settlement footprint, using the same facilitator flow as Base and other EVM chains.

Current Support

Settlement Model

On Optimism, the facilitator validates the EIP-3009 transferWithAuthorization against the payment requirements — same as Base. Recipient, token, amount, and timing are all checked before settlement.

What Integrators Should Validate

1. The route uses the correct Optimism network identifier (eip155:10)
2. The payment asset and recipient match the expected requirements
3. The facilitator accepts the payload and settles successfully
