Contract Interaction Flow

Use contract-interaction flows when an EVM wallet should approve and deposit ERC-20 funds through the SDK.

Requirements

Requirement	Why
evmRpcUrl or evmPublicClient	The SDK needs public ERC-20 reads
Wallet adapter with sendEthTransaction	The SDK asks the wallet to broadcast approval and deposit transactions
Token base-unit amount	The SDK sends protocol amounts as integers

Shape

import { Chain } from "@liquidium/client";

const supplyFlow = await client.lending.supply({
  mechanism: "contractInteraction",
  profileId,
  poolId,
  action: "deposit",
  chain: Chain.ETH,
  walletAdapter,
  account: evmAddress,
  amount,
});

console.log("Deposit txid", supplyFlow.txid);

Use this for account-based ETH stablecoin flows. Simple Loans return their own deposit and repayment targets.
