Nexus Elements - Bridge Deposit

Overview

Install the Bridge Deposit widget for a simple bridge-and-execute deposit flow. This is lighter than the full Deposit widget.

Prerequisites

  • NexusProvider installed and initialized on wallet connect.
  • Wallet connection configured; you have the connected wallet address.

Install (shadcn registry)

  1. Ensure shadcn/ui is initialized (components.json exists).
  2. Ensure registry mapping exists:
"registries": {
  "@nexus-elements/": "https://elements.nexus.availproject.org/r/{name}.json"
}
  1. Install:
npx shadcn@latest add @nexus-elements/bridge-deposit

Alternative:

npx shadcn@latest add https://elements.nexus.availproject.org/r/bridge-deposit.json

Manual install (no shadcn)

  1. Download https://elements.nexus.availproject.org/r/bridge-deposit.json.
  2. Create each file in files[].target with files[].content.
  3. Install dependencies listed in dependencies and each registryDependencies item.

Usage

import NexusDeposit from "@/components/bridge-deposit/deposit";
import { SUPPORTED_CHAINS, TOKEN_METADATA } from "@avail-project/nexus-core";
import { parseUnits } from "viem";

<NexusDeposit
  address={address}
  chain={SUPPORTED_CHAINS.BASE}
  token="USDC"
  heading="Deposit USDC"
  destinationLabel="Deposit to Aave"
  embed={false}
  depositExecute={(token, amount, chainId, userAddress) => {
    const decimals = TOKEN_METADATA[token].decimals;
    const amountWei = parseUnits(amount, decimals);
    return {
      to: "0x...",
      data: "0x...",
      tokenApproval: {
        token,
        amount: amountWei,
        spender: "0x...",
      },
    };
  }}
/>

SDK flow mapping

  • Uses sdk.bridgeAndExecute(...) under the hood.
  • Relies on intent + allowance hooks (intent, allowance) for confirmation UI.
  • Progress updates come from NEXUS_EVENTS.STEPS_LIST and NEXUS_EVENTS.STEP_COMPLETE.

Props (NexusDepositProps)

  • address (required): connected wallet address
  • chain (required): destination chain id
  • token (optional, default "USDC")
  • chainOptions (optional): customize source chains list
  • depositExecute (required): returns { to, data, value?, tokenApproval? }
  • heading, embed, destinationLabel

Notes

  • Use embed={true} to render inline, otherwise a modal is shown.
  • This is distinct from the full deposit widget which uses swapAndExecute and broader asset selection.
