DApp Connector

DApp connectors

NuFi offers several DApp connectors allowing it to interact with DApps across multiple blockchains. Below are instructions/resources clarifying how to integrate them.

Cardano

NuFi's Cardano connector implements the CIP-30 standard and the API should behave the same as Flint wallet's CIP-30 connector, except it's injected as window.cardano.nufi. More info at https://www.cardano-caniuse.io

Ethereum / Milkomeda C1 / Polygon

NuFi's Ethereum connector implements Metamask's API documented here: https://docs.metamask.io/guide/ethereum-provider.html#methods. When integrating NuFi we suggest following the eip-6963 standard.

Legacy eip-5749

Nufi still supports eip-5749 standard and you can load NuFi from window.evmproviders. However, its prefered to use eip-6963 instead.

Legacy window.ethereum injection

NuFi still offers legacy support and also tries to inject itself intowindow.ethereum, but we discourage using this approach and rather move to eip-5749 proposal. Note that in that case, NuFi will not inject its API if it detects Metamask or other wallet injecting into the window.ethereum object, to avoid interference with these wallets. Therefore, in order to use NuFi's Ethereum connector you need to make sure that there are no other active Ethereum wallet extensions (i.e. they must be disabled/uninstalled).

EVM chains currently supported by NuFi's connector:

• Ethereum

• Milkomeda C1

• Polygon

Solana

NuFi's Solana connector can be integrated through the Solana Wallet Standard (https://github.com/anza-xyz/wallet-standard). More info here.

Flow

NuFi works with the official fcl-js SDK and is fully integrated with the fcl-discovery service. If you want to integrate NuFi directly, the parameters needed for that can be found here.
