Relay Builds Its Own Chain After $20B in Volume Proved the Product Could Support One
The conventional playbook for blockchain infrastructure teams is to launch a dedicated chain first, then search for users. Relay inverted that sequence: it built a multichain payments network on shared infrastructure, processed more than 100 million transactions and $20 billion in volume across 85 networks, and only then built a chain the product had earned the right to need.
Relay, a multichain payments network, has launched Relay Chain, a dedicated settlement layer built using the Sovereign SDK and Celestia as its data availability backbone. The chain went live as the project reported more than 100 million transactions processed and $20 billion in total volume across 85 supported networks. In February 2026, the company closed a $17 million Series B led by Archetype and Union Square Ventures to fund the transition. The case study describing the architecture was published by Celestia in May 2026.
How the protocol works
Relay operates on an intent model. Rather than locking assets in a bridge contract, a user broadcasts a desired outcome, for example moving USDC from Ethereum to Base, and a network of competing relayers races to fulfill it by fronting capital on the destination chain. The origin chain then repays the relayer. This approach avoids the pooled-liquidity design that made earlier bridges targets for exploits, including high-profile incidents such as the Ronin and Wormhole hacks.
Before Relay Chain, the protocol settled on general-purpose networks shared with other applications. That created a compounding set of problems: gas costs fluctuated with network congestion, orders had to be batched to save fees (which introduced delays), solver capital spread thin across dozens of chains, and competing applications created blockspace contention that made execution timing unpredictable. Building a dedicated chain eliminated all four friction points by giving Relay control over its own blockspace and fee structure.
Technical performance
According to the Celestia Blog case study documenting the architecture, Relay Chain delivers approximately $0.005 per settled order. The Sovereign SDK documentation corroborates soft confirmations in about one millisecond, P99 latency under 10 milliseconds, and throughput exceeding 30,000 user operations per second. The Sovereign SDK is a Rust-based framework that posts transaction batches to Celestia. Celestia handles data ordering and availability without executing Relay's application logic, which lets the chain scale independently of Celestia's own throughput limits.
Celestia currently serves 37 rollups in production and has processed more than 160 gigabytes of rollup data. Data posting costs roughly $0.35 to $0.45 per megabyte as of early 2026. Celestia's Fibre protocol, announced in January 2026, targets one terabit per second of blockspace across 500 nodes, representing a roughly 1,500-fold improvement over the project's original throughput roadmap. Relay Chain is among the production deployments positioned to scale toward that expanding ceiling.
The design philosophy, as Celestia's case study frames it: build the product first, then build the chain when the product demands it. That sequencing inverts the typical appchain argument, where teams often launch a dedicated chain before establishing any user base. Dedicated chains are now a mature and well-documented pattern in production: the Cosmos SDK alone powers more than 60 appchains currently running live, giving developer teams a broad set of prior examples to draw from.
Why this matters for users outside the United States
The practical implications are clearest in high-remittance markets. Sub-Saharan Africa received more than $205 billion in on-chain value between July 2024 and June 2025, a 52 percent year-over-year increase. Nigeria ranked sixth and Ethiopia twelfth on the 2025 Chainalysis Crypto Adoption Index, illustrating where that activity is most concentrated. The average fee for sending $200 into the region still sits at 8.9 percent through traditional corridors. A settlement layer capable of routing value across 85 chains at sub-cent cost represents a structural improvement for anyone operating in those corridors.
South Africa is now the continent's most regulated digital asset market, with 310 licensed crypto service providers approved by the FSCA as of March 2026 and stablecoins accounting for more than 45 percent of regional crypto volume. In October 2025, South Africa successfully exited the FATF grey list, a development that signals the country's regulatory environment is stabilizing in a direction that supports both institutional participation and developer activity. Relay already routes USDC, USDT, and native assets across its supported chains. An interoperability layer with predictable, near-zero settlement costs could reduce friction between South Africa's 650,000-plus merchant endpoints and decentralized financial rails.
South Asia presents a similar picture. India, Pakistan, and Bangladesh collectively receive close to $200 billion in remittances annually, with average transfer costs of 5 to 7 percent, well above the UN's 3 percent target. Tron-based USDT dominates retail payment flows in the region at roughly 70 percent of transactions processed through CoinGate, a major regional payment processor. That pattern reflects a market already operating across fragmented chains, and Relay's architecture is designed precisely for that fragmentation.
India's regulatory environment adds a layer of compliance overhead for developers building on top of Relay Chain's APIs. The country applies a 30 percent flat tax on crypto gains and a 1 percent Tax Deducted at Source on transactions. That structure has suppressed domestic on-chain volume and pushed users toward offshore platforms, making it a material consideration for any team building India-facing products on Relay Chain infrastructure.
Pakistan is one of the largest remittance-receiving countries globally and has developed a substantial base of informal crypto users operating within a still-evolving regulatory framework. That combination of high remittance demand and regulatory uncertainty creates a compelling use case for low-cost cross-chain settlement while also posing compliance questions that developer teams will need to navigate when building products to serve that market.
Market context and developer implications
Relay is currently integrated with Phantom, MetaMask, OpenSea, and Coinbase Wallet, and the network has accumulated more than 6 million users. The broader market for cross-chain bridge infrastructure was valued at $115 million in 2024 and is projected to reach $430 million by 2032, with Asia-Pacific growing at a 27.9 percent compound annual rate through 2033.
The Relay Chain case study also functions as a template. The Sovereign SDK is publicly available, and the combination of sub-cent data availability costs on Celestia and 30,000-plus operations per second throughput makes the product-centric chain approach replicable for developer teams outside well-funded Western hubs. Teams in Lagos, Nairobi, Mumbai, or Karachi building specialized payment or lending products now have a documented architecture to follow, not just a thesis to argue about.
