InfinitySwap

InfinitySwap is now Bitfinity Network, a next-generation Ethereum Virtual Machine (EVM) that serves as a Layer 2 for Bitcoin and Bitcoin on-chain assets, built on the Internet Computer (ICP). Bitfinity delivers high-throughput (1000+ TPS) EVM execution with full Ethereum tooling compatibility (MetaMask, Remix, Hardhat) exposed through a standard Ethereum JSON-RPC endpoint, letting developers deploy Solidity smart contracts and bridge BTC, ckBTC, and other assets. The project also maintains the Bitfinity Wallet, the Bitfusion bridging SDK, canister SDKs for the Internet Computer, and the InfinitySwap decentralized exchange heritage. Backed by Polychain, it targets DeFi builders who want Bitcoin-secured, EVM-compatible infrastructure.

InfinitySwap publishes 1 API on the APIs.io network. Tagged areas include Company, Defi, Blockchain, Ethereum, and EVM.

InfinitySwap’s developer surface includes documentation, getting-started guide, engineering blog, support, signup flow, sandbox, authentication, and 9 more developer resources.
