[ For teams ]

Launch stablecoin Earn with one API.

1Tx is yield access infrastructure: one API and router for DeFi yield discovery, routing and execution across Aave, Morpho, Compound, Euler and Fluid — so your team ships an Earn product instead of one integration per protocol and chain.

Who we work with

The pain, then the wedge.

Wallets

Your users hold idle stablecoins, but swap → approve → deposit → monitor → withdraw is too complex to ship as-is — and you don't want to integrate every lending protocol separately.

One-click Earn across protocols, inside your wallet.

Fintechs & neobanks

Stablecoin savings is attractive, but DeFi plumbing is hard to build — and harder to explain in a familiar user experience.

Offer a simple stablecoin Earn experience while 1Tx handles vault discovery, routing and execution infrastructure.

Exchanges

DeFi Earn means protocol integrations, monitoring and confusing user education — slow, expensive and support-heavy.

Multi-protocol Earn coverage through one API and router.

Business value

What you get

  • Launch Earn and yield products faster — one integration instead of one per protocol and chain.
  • Less engineering to maintain: the registry and router absorb protocol upgrades and new markets.
  • Better conversion: swap and deposit settle atomically in a single user-visible step.
  • Multi-protocol discovery and execution from one interface, with normalized APY/TVL metrics.
  • Optional referral fee on executed flow (up to 5%) — the integration can pay for itself.
  • Agent-driven allocation, rebalancing and withdrawal with guardrails, when you're ready for it.

Integration

How integration works

  1. 01

    Discover

    GET /instruments returns the live registry — filter by chain, protocol, asset or yield, all in one normalized shape.

  2. 02

    Build

    POST /transactions/buy returns the unsigned transaction set for a deposit, cross-chain CCTP routing included when needed.

  3. 03

    Execute

    Your users' wallets sign — EOA or gasless Safe smart accounts with gas paid in USDC. You never take custody; neither do we.

Status

Where we are, honestly

  • Live on Base, Arbitrum and Unichain mainnets, covering Aave, Morpho, Compound V3, Euler and Fluid.
  • The 1Tx router is unaudited. The underlying protocols are audited; the router is the new surface. An audit is in progress — it's the gate we clear before broad institutional rollout.
  • We work with a small number of design partners directly: you get engineering access and influence over the roadmap; we get a production-grade integration to harden.
