Porto beats ERC4337 by miles in gas which means both in cost & throughput.
3 mainnet x-chain demos of using Porto in DEXs in Safari mobile. Self-custodial, no passwords, no extensions, cross-app, cross-device. Batching, sponsorship, state of the art gas costs, 1-click interop and so much more. 1/3 @Uniswap:
Porto is now production-ready & fully open source! Porto’s north star is to enable secure and programmable web-native crypto payments & finance without passwords, or browser extensions. Integrate now in 2 lines of code and in less than 1 minute: `pnpm i porto`.
