Not claiming it is. To add a little more depth to the topic And to be precise there will never be the bridge you're asking for between the current Bitcoin network and altcoins, as this is factual impossible.
Take wBTC as what it is. A "Bitcoin on the bitcoin network"-entitlement token issued by the wbtc.network. It's not a substitute to the Bitcoin network. Want to do something with Bitcoin entitlement tokens on Ethereum? Cool. To wBTC you go. I think it is a great project with great backing.

Thanks for your interest. If the project has traction, there could be some cool system in place to involve the community in governance or providing the liquidity. Currently, this is not something I or Rob would like to do, as without a community, this is BS IMO.

yes, the BTC shown on the ETH-BTC and BTC-ETH swap is native BTC Bitcoin.


I will top up the amount of ETH and BTC in the pool soon, but first I want to see if there is an overall demand for the swap.

Hello everyone,

After a lot of coffee spent on developing and finally launching an Ethereum bridge last week, I'm happy to do my own announcement post here now.
Andy already did an announcement for the bridge in the Altcoin channel: https://bitcointalk.org/index.php?topic=5425902.new#new

While working on the project, I was interested in implementing a bridge for Bitcoin to Ethereum with wrapped BTC from the wbtc network.
I developed a deadbeat simple swap between the two native base currencies BTC and ETH.
Before going deeper into the WBTC bridge itself, I wanted to get some early feedback first.

Features:
- No KYC
- Fair rates and fees IMO
- Change of slippage to your liking

BTC to ETH: https://swapbridge.io/btc-eth-bridge/
ETH to BTC: https://swapbridge.io/btc-eth-bridge/

I did a comparison to Changelly, in which they gave me a quote of 1.3398 ETH for 0.1 BTC. SwapBridge offers 1.3416 ETH.
The rate is directly taken from Uniswap's ETH/WBTC pool with 0.25% and transaction fees deducted to cover costs.


Currently, I'm writing some blog articles, like the one I did on different Bitcoin address types while getting deeper into the bridging topic.
BTC address types: https://swapbridge.io/blog/different-bitcoin-addresses/

I'm hoping to build out the project, for it to become a one-stop platform to easily swap and bridge all common tokens and native coins between different blockchains.

Feel free to ask me any questions you might have.
Your feedback is greatly appreciated!

Best, Rob

Warm welcomes,


there is no launching a crypto related project without doing an announcement post on [Suspicious link removed] in 2017 I got myself into a mess by using multiple chains daily. Somewhat glad I recently stopped using Solana and trim down on wallets to keep track of. Telling you – taxes ain't fun.

While there are already some great projects maybe going into a direction I was looking for, I couldn't keep myself from getting my hands dirty doing a cross-chain bridge or swap that also includes non EVM-chains. There are some more decentralized-leaning project's out there, but those come with a speed/cost tradeoff. When I was moving smaller quantities cross-chain, I always went for the most efficient option and with the project, I tried to cater to this need of mine. The available features are sparse and not completely to my liking, but without spending too many long nights and getting thousands of government-tokens poorer, I wanted to see first, if anyone is interested in it to use. Anyway, here is what came of it:

Bridge ETH, MATIC, BTC, DAI, USDC, USDT from Ethereum to Polygon Matic and Binance Smart Chain and back.

I'm hoping for someone to find the offering useful. I want the focus on smaller quantities with speed and low costs to be the project's number one priority. For larger quantities, which I, personally, don't like to trust in other hands than my own, there are some great alternatives already.

If there is interest, I thought about doing less block confirmations, which are scaling with the transaction value. There are definitely some speed and gas cost optimization left. Currently, SwapBridge is charging a flat network fee denoted in the bridged asset. The network fee itself is dependent on the route and asset. For example, the network cost of bridging ETH from Ethereum to Polygon Matic is 0.00001 WETH or €0.012 ($0.013, for non-EU-plebs). Furthermore, all routes charge 0.25% of the remaining amount to cover the costs.

On the project, Rob is doing the Bitcoin side. The WBTC bridge isn't ready yet on the Ethereum side, though he already launched a swap feature (Roundtrip between Ether and Bitcoin).

There is so much stuff I'd love to do, like a horizontal expansion into offering more chains and tokens. And even more a frontend  rework, for it to be having more elegance like Uniswap. Moreover, entering the receiving amount first and doing a backwards calculation!

Really looking forward to feedback or questions.

Best, Andy
