RioSwap Public Testnet is Live!
September 23, 2025

Every major innovation begins with a strong foundation. For Mintlayer, that meant years of building the core infrastructure for a native Bitcoin cross-chain swap system powered by HTLCs. This groundwork made it possible for Bitcoin to trade across chains without ever leaving the user’s control. Today, that foundation comes to life with the launch of a front end built for real users.

The launch of RioSwap marks an important step in Bitcoin’s evolution, where decentralized markets, liquidity, and real-world finance begin to converge, tapping the potential for trillions in idle $BTC to enter the on-chain economy, now driven by Mintlayer.

RioSwap is the FIRST-EVER BTC-native cross-chain decentralized exchange built on Mintlayer’s atomic swap technology. It enables direct Bitcoin swaps without the need for wrapped assets, bridges, or custodians, preserving the security and self-custody that define Bitcoin.

With the Public Testnet now live, we invite you to explore, test, and share your feedback to help us refine the experience ahead of the mainnet launch.

Your Address Checks Itself

One typo in a bech32 address gets caught, located, and corrected before signing. On 0x chains, almost any lowercase string is a valid address. Security at Mintlayer starts at the format level.

An Append-Only Attestation Layer for AI Decisions

Proofs and attestations only become evidence when they live somewhere an auditor can find them, with a timestamp nobody disputes and no way for the operator to revise the collection. Bitcoin-anchored infrastructure provides exactly that.
