We just made building on Train a lot easier. You can now mint test tokens directly from our new Faucet, so you and your agents can perfect your integrations without spending a single penny

Try it yourself: testnet.train.tech/

That’s it for today! If you care about trustless swaps, privacy-preserving apps, or protocols anyone can join, reach out — we’d love to build this together: t.me/trainprotocol

Aztec Testnet support is live on TRAIN. TRAIN verifies swaps locally, so no off-chain coordinator needs to inspect the details — a natural fit for privacy-preserving chains. We already supported Aztec Devnet. Today, our integration moves to @aztecnetwork Testnet.

Destination amount support is live on TRAIN. Most swap flows start with the input: choose what you send, then see what arrives. But real-world flows often start from the other side: the amount that needs to arrive. TRAIN now supports specifying what should arrive.

That same Passkey flow is what makes one-click swaps possible. The user confirms once, and TRAIN handles the rest locally. Combined with faster solver infra and reward mechanisms baked into the protocol, trustless swaps on TRAIN are quick and simple.

Passkey accounts are live on TRAIN. Atomic swaps rely on a secret to coordinate the exchange without a trusted third party. With Passkeys, TRAIN handles that lifecycle locally: the secret is derived from the user’s passkey, stays under their control, and keeps the flow simple.

We’re building TRAIN so cross-chain swaps can be trustless, permissionless, privacy-preserving — and still feel fast and simple. Today’s update adds: • Passkey accounts • Fast one-click swap flow • Destination amount support • @aztecnetwork Testnet support Details below

.@bot_insane at @trustlessconf | @EFDevcon Argentina 2025! In his recent talk at the trustless:// conference, our co-founder Aram shared the vision behind the TRAIN protocol and why we’re building it. “Interop is not an end-user product. It's infrastructure.” That infrastructure, Aram explained, should be open, secure, and neutral. And that’s exactly what TRAIN is. An intent-based, cross-chain bridging protocol that removes the need for third-party verifiers and approvals – no oracles, no validators, no multisigs.

🙌🙌

Want to be a part of the next phase of cross-chain interop? TRAIN is open to you! If you want to integrate a network, run a solver or meet your apps interop needs in a trustless way, reach out to us and join TRAIN: t.me/trainprotocol

The TRAIN protocol contracts, solver agent, and bridging dApp are open-source under the MIT license. The PreHTLC contracts are currently deployed on EVMs, @solana, @Starknet, @fuel_network, and are in active development on @aztecnetwork, @Bitcoin, @ton_blockchain, @Stacks, @SuiNetwork, @Aptos, XRP 👉 docs.train.tech/protocol/int…

TRAIN is permissionless. This means any network can be a part of TRAIN – EVMs, altVMs, rollups, or appchains. And that’s not all. Anyone can run a solver, add tokens and earn bridging fees – all without approvals.

TRAIN is an intent-based system secured by Atomic Swaps (HTLCs) and Local Verification. When bridging with TRAIN, users send their intents to solvers, who fulfill them using PreHTLCs (our version of Atomic Swaps). Neither side ever gives up custody of funds. Every step is fully transparent and can be verified locally. No external dependencies or trust assumptions.

We offer a solution: a protocol designed to solve interop’s two biggest issues – security and scalability.

The reality of blockchain interoperability today is fraught with security risks. Every existing interop solution is either centralized or depends on centralized operators. And what if you want to add a new chain? You’ll definitely need someone’s approval.
