FIRO Goes Multichain: rsFIRO is Live on Rosen Bridge

FIRO is now live on Rosen Bridge, meaning you can move native FIRO to other blockchains as rsFIRO, trade it on decentralized exchanges, and redeem it back to native FIRO. Trading pools are already live on Uniswap (Ethereum), PancakeSwap (BNB Chain), and MewFinance (Ergo).

This matters because it gives the community a way to build markets around FIRO without waiting for exchange listings. Anyone can create a pool or contribute liquidity on these permissionless exchanges today.

A few important things to keep in mind:

• rsFIRO is not a private token. Its transfers and DEX trades are public. For private transactions, return to native FIRO and use Lelantus Spark.

• Always verify the contract address before buying. Fake tokens can copy a name or symbol - the contract address is the only definitive check.

  • ETH: 0x2744ea5ac9b11cb5e3cd63d3a88e858336aeddc2

  • BNB Chain: 0x13cDb5F7f398F6AF2CC3B34EB04476af3488853f

• Do not send rsFIRO to a native FIRO exchange deposit address. They are different assets on different networks.

Bridging takes 2-4 hours through app.rosen.tech. You will need transparent balance and a supported wallet (Campfire or Firo-QT). For smaller or quicker transfers, buyfiro.app also supports FIRO/rsFIRO bridging.

Reuben Interviewed at Common S3nse by CryptoFocus

Dutch crypto publication CryptoFocus sat down with Reuben at Common S3nse in Amsterdam for a 17-minute interview titled "The frozen account behind the argument." Reuben shares the story of having his bank account frozen for an entire year after unknowingly receiving USDT from a counterparty involved in a scam - despite being cleared by police. It is a personal, grounded account of why financial privacy matters in practice, not just in theory. Well worth a read or a watch.

Firominer 1.4.0: Open-Source, No Dev Fee, Competitive Performance

Firo's reference miner has been updated. Firominer 1.4.0 now supports both NVIDIA and AMD GPUs with performance within roughly 1% of popular closed-source miners - and charges zero developer fee. Since closed-source alternatives typically charge up to 2%, Firominer actually comes out ahead when fees are counted.

It also supports solo mining directly from your own Firo node - keeping block production decentralized without a pool fee on top.
