First RGB asset swap on Lightning Network

KaleidoSwap executes atomic stablecoin swap on Lightning mainnet using the RGB protocol.

The decentralized exchange KaleidoSwap has successfully completed the first atomic swap of an RGB asset through the Lightning Network on mainnet. This is not a controlled environment test, but a real transaction that used authentic RGB assets, operational Lightning channels, and a trustless swap system.

The transaction involved the tUSDT asset, an RGB20 representation of the USDT stablecoin transferred into the RGB ecosystem via the UTEXO.com bridge.

The transaction numbers show:

• swap of approximately 12,000 satoshis for 13 tUSDT;
• channel with capacity of 100,000 satoshis and 90 tUSDT;
• instant settlement without mempool traces;
• both nodes operating on Raspberry Pi 4 with 4GB RAM.

The execution was instant, private, and required only a few satoshis in fees.

RGB technology extends Lightning Network functionality by enabling the transfer of assets other than BTC. RGB-enabled Lightning channels make atomic swaps possible with the same trustless guarantees as bitcoin payments.

Atomicity is guaranteed through Hash Time-Locked Contracts (HTLC): either the swap completes entirely, or no transaction is executed.

The advantages over traditional solutions are multiple: on-chain fees only required for opening and closing channels, instant settlement without double spending risk, impossibility for other operators to see and frontrun transactions, and superior privacy.

A technical detail concerns the hardware used: both RGB Lightning nodes involved in the swap operated on Raspberry Pi 4 with only 4GB of RAM, simultaneously running a Bitcoin full-node and an Electrum server. Despite the modest hardware specifications, the nodes supported channel management and swaps without issues.
