And the biggest highlight of 2025: TRAIN Protocol Mainnet launch 🙌 @trainprotocol is a credibly neutral, trustless, and intermediary-free approach to cross-chain asset bridging. You’ll be hearing way more about it in 2026. Drop us a note if you want to build on top of TRAIN!

.@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

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,

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

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.

Today, we signed the Trustless Manifesto! A pledge to build systems where correctness and fairness depend on math and consensus, not intermediaries. These are the same principles that shaped TRAIN from the start

@trainprotocol is an intent-based, cross-chain asset bridging protocol that requires no third parties - no oracles, no verifiers, no validators. That sounds aligned with trustlessness to us, and so we're looking forward to hearing all about it from @bot_insane

We are building a best-in-class privacy bridge @trainprotocol on top of a best-in-class privacy network. Trust-minimized, no third parties, private user and solver.

Among all other things @trainprotocol is going to be a killer privacy bridge from/to @aztecnetwork

This is what a single @trainprotocol transaction looks like: no intermediaries, no multisigs. Just the Solver and the User performing Atomic Swaps.
