Relay Chain has processed over 100 million transactions and clocked a transaction volume exceeding $20 billion. The milestone comes as the network runs on a dedicated chain built atop Celestia, an architecture designed to tackle the scalability and cost bottlenecks that have long dogged blockchain transactions.
The Celestia-based design
Relay Chain doesn't run on a general-purpose Layer 1. Instead, it uses its own dedicated chain built on Celestia, a modular data-availability network. That means transaction data gets posted to Celestia's consensus layer while execution happens on Relay Chain's own chain. The separation lets each part scale independently – the chain handles throughput without competing for block space on a crowded mainnet.
Scalability and cost in practice
The architecture directly addresses two pain points. First, scalability: because Relay Chain's dedicated chain can adjust its parameters, it's not limited by the throughput of a shared base layer. Second, cost: by batching data commitments to Celestia instead of settling every transaction on Ethereum or similar networks, fees stay low even as volume spikes. The 100-million-transaction mark shows the design works at scale – and the $20 billion volume suggests real economic activity, not just noise.
What comes next
Relay Chain isn't slowing down. With the architecture proven out at these volumes, the team can focus on onboarding more users and applications. The next milestone – whether it's 200 million transactions or a push into cross-chain – will test whether the Celestia-based model can keep costs low as the network doubles again.
