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

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
