# Pricing

Builders can pay for additional access tiers beyond standard relay access. All prices are billed monthly in USD.

## Services

The services below can be purchased independently and are mutually exclusive. All services are billed monthly in USD.

#### **1. Co-location**

Place builder infrastructure alongside a relay region to reduce network latency. Co-located instances can expect an average network round-trip latency of ***75us***, measured with a TCP handshake probe (\*).

Co-located instances will be hosted within the Titan Helix AWS account, with SSH access restricted exclusively to the third party. Users can select their preferred operating system and disk configuration during provisioning.

AWS Supported regions - North Virginia (`us-east-1`), Frankfurt (`eu-central-1`), Tokyo (`ap-northeast-1`)

Each region included will incur the following costs

1. **Service fee -** USD 5000
2. **Instance cost** (subject to availability in the region): c8a.8xlarge (USD 1500) or c7a.8xlarge (USD 1400)
3. **Data transfer cost**: AWS charges for data egress, which will be reflected on each monthly bill

#### 2. Extended feature support 

Fixed cost of USD 3000 for the following features available across all relay regions

1. **TCP Bid Submissions -** Access to the persistent TCP endpoint for latency-sensitive bid submission, as an alternative to HTTP submitBlock
2. **Fast** **sigverify -** Builders authenticate using a provided API key, which is validated against their public key. This bypasses BLS signature verification, reducing submission latency by approximately 2 ms.
