To serve billions of users we need a way to serve DeFi into financial apps in a way that’s fast, reliable, and built for scale.

Today, we’re introducing Tachyon - our high-speed, low-latency relayer and bundling infrastructure, purpose-built to move DeFi into the next era.

Infra is the bottleneck for DeFi

Despite crypto’s growth over the past decade, one core piece of the puzzle has been consistently overlooked: transaction infrastructure. The ability to execute onchain actions quickly, seamlessly, and across multiple chains remains frustratingly difficult for users and builders alike.

Many teams are also forced to build in-house relayers, managing infrastructure that’s difficult to scale, maintain, or secure, all while user expectations rise and new chains emerge weekly.

These are not minor inconveniences. They are blockers to adoption at scale.

We’re building the fastest relayer for DeFi

Tachyon is Rath’s answer to the broken infra layer.

Tachyon is a purpose-built relayer and bundler that enables fast, low-latency, and cost-effective transactions across a growing network of blockchains.

From the ground up, Tachyon is built for performance.

It enables developers to submit transactions in under 150 milliseconds, on average and supports over 16 chains(EVM and alt-VMs).

We also simplify the UX by offering unified balances, so developers and users don’t need to manage gas or assets across every chain manually.

Tachyon in Action

Tachyon is built to serve the wide rapidly evolving needs of the crypto space. Here are potential use-cases that Tachyon will be great at:

• Wallets: Enable seamless UX for transactions by abstracting gas fees and chain complexities.

• DeFi: Power all liquidation and keeper activity on your protocol with the lowest latency possible.

• Multichain apps: If you are app is live on multiple chains, you can use Tachyon to perform multiple transactions across different chains, simultaneously.

Whether you’re building a mobile wallet, a trading protocol, or a game - Tachyon lets your users move instantly, no matter where they are.

Tachyon is the foundation for Rath

At Rath, our vision is to become the universal rails for onchain yield and liquidity - making DeFi accessible to any wallet, any app, and eventually, any user.

But none of this is possible without infrastructure that can support it. We needed the fastest, most reliable relayer in the space - one that could serve billions of transactions, across chains, with minimal friction. We also want to bring it to all the DeFi applications in the space to allow for blazing fast transaction tracking and relaying.

Whether you're a DeFi protocol, a wallet, a game, or a new kind of app, you can now plug into the fastest, most reliable transaction layer in crypto.

Crypto is mainstream, and DeFi still feels like a hack…

Crypto is no longer in the experimental phase it was during DeFi summer. The space has matured and user needs have changed. Every crypto product however is still build around an active, degen user that moves around multiple chains to hunting for high APYs!

This user is no longer the majority.

https://x.com/0xNairolf/status/1907038490111471811

What we’re seeing instead is a new wave of access points - wallets, consumer fintechs, and institutional platforms becoming the primary way for users to manage their crypto-assets. These products offer simpler UX, better user trust, and native distribution. With regulatory clarity improving, more institutions and fintechs are adopting this model and building their own frontends on crypto.

This is a healthy evolution and it’s how crypto goes mainstream. But the existing infrastructure isn’t ready for it.

Most DeFi protocols are still locked inside their own frontends, on isolated chains, and rely on complex flows and incentive programs just to get new users to show up. Meanwhile, wallets and frontends bear the full weight of integration: building bridges, parsing standards, managing yield sources, all just to offer users basic financial features.

If crypto needs to power the next wave of consumer crypto, we need to rethink the model entirely.

We need to shift from a world where users come to protocols, to one where protocols go to users.

Introducing Rath

Rath is the universal rails to bring DeFi yield to wallets and modern fintechs. We enable any application to bring DeFi yield for their users assets natively within their frontends.

Rath enables wallets and consumer apps to plug directly into DeFi primitives like staking, lending, and structured products—without needing to integrate individual protocols one by one.

At the same time, it transforms existing DeFi protocols from isolated, self-contained systems into modular liquidity engines that can power any app, wallet, or interface.

How Rath Works

At its core, Rath introduces a new primitive: auctioned liquidity - capital that lives in wallets and apps, surfaced and deployed on demand through real-time auctions. DeFi protocols bid to access this liquidity ensuring wallets always get the best yield opportunties for their users.

At launch, we plan to add permisioned support for Aave, Fluid, Ethena, Resolv, Morpho, Lido, Rocketpool, Curve, and more.

We will also slowly expand towards permissionless solvers to help frontends to tap into every DeFi protocol opportunity across chains and for every asset in user wallets. Solvers will also simplify UX so user funds will automatically swapped, bridged and deposited into the protocol.

Rath is also built on top of the EIP-7702 standard which ensures users funds remain non custodial and solvers only perform deposits on behalf of users without need of creating any extra vaults. This ensures wallets do not take on any extra layer of security risk on top and also do not need to manage any new protocol vaults for the users.

What Rath Unlocks

Rath gives wallets, consumer apps, and fintechs the infrastructure to embed DeFi into everyday financial experiences—without the UX tradeoffs.

With Rath, apps can:

• Offer native yield on idle balances

• Build auto-compounding vaults and structured products

• Surface personalized yield opportunities in real time

• Route user liquidity to the highest-bidding protocols

All of this happens non-custodially, behind the scenes, through a competitive auction layer.

No lockups. No chain friction. No protocol bloat.

The Future of Yield Is Invisible

We believe crypto is heading toward its embedded era.

Yield, once the domain of power users and complex vaults, is becoming a productized utility.

Every wallet, consumer apps, and fintech interface will become distribution layer for DeFi and quietly delivering yield through products people already use.

In that world, the protocols that matter won’t be the ones with the biggest numbers—they’ll be the ones that can get value to users, wherever they are.

Rath is our bet on that future—a protocol that turns DeFi into a service, yield into a simple product feature, and liquidity into a competitive marketplace for the next wave of crypto-powered apps.
