Earn

How Trails supports common flows for DeFi protocols, yield opportunities, perpetual exchanges, vault deposits, and more to accelerate TVL and volume.

Earn with Trails

Trails simplifies DeFi yield deposits by natively integrating with protocols across chains — surfacing APY, TVL, and other metrics, and handling all swapping and bridging to the vault or pool token in a single transaction.

Use cases

• Deposit into lending protocols like Aave or Morpho
• Fund yield aggregator vaults like Yearn Finance
• Fund auto-compounding yield strategies

Examples

Deposit into a user-selected vault

Trails has integrated multiple DeFi pools and vaults across Aave, Morpho, and others. Users can pick from the integrated set out of the box:

EarnWidget.tsx

import { Earn } from '0xtrails/widget'

export const App = () => {
  return (
    <Earn
      apiKey="YOUR_API_KEY"
      renderInline={true}
      theme="auto"
      onEarnSuccess={({ sessionId }) => {
        console.log('Deposit completed:', sessionId)
      }}
    />
  )
}

Deposit into a specific DeFi pool

For natively supported protocols like Aave and Morpho, use composable actions — no ABI encoding required. The lend and deposit builders handle the contract calls internally:

import { useTrailsSendTransaction, lend, erc20Utils } from '0xtrails'

export function AaveLendButton({ recipient }: { recipient: `0x${string}` }) {
  const { sendTransaction, isPending } = useTrailsSendTransaction({
    actions: [
      lend({
        marketId: 'base-usdc-aave-v3-lending',
        amount: '100',
      }),
    ],
  })

  return (
    <button
      disabled={isPending}
      onClick={() =>
        sendTransaction({
          to: recipient,
          tokenAddress: erc20Utils.USDC.addressOn('base'),
          tokenAmount: '100',
        })
      }
    >
      {isPending ? 'Sending...' : 'Supply 100 USDC to Aave'}
    </button>
  )
}

Use useEarnMarkets to discover available marketId values at runtime. For protocols not covered by the action builders, see Composable Actions — custom.
