Supply tokens for the first time

Choose a route, decide about collateral, preview, and confirm.

4 sections Beginner friendly

Before u start

Supplying moves the selected token from ur wallet into a market. Start with a connected wallet, the required ERC-20 token, and the network’s gas token for transaction fees: ETH on Ethereum and OP Mainnet, or AVAX on Avalanche. Read the token and Spoke names carefully: the same token may have more than one route.

u can reach Supply from an expanded Spoke asset, an Asset comparison card, or an Opportunity. The Hub inventory’s Review button also opens the drawer on Supply. None of those entry buttons moves money.

Make a supply

  1. Open the route and choose Supply. Check the asset, Spoke, and Hub in the drawer.
  2. Enter the amount in token units. Use a decimal such as 12.5, without commas or an exponent.
  3. Decide whether to enable the supply as collateral. The checkbox is offered only for eligible assets and starts off in the main site.
  4. Select Preview transaction. Read the result and any error, including the health-factor information if u already have debt.
  5. Select Confirm supply in wallet. If prompted for a token-spending approval first, review that request separately, then review the supply request.
  6. Wait for confirmation. Use View transaction to inspect the receipt, then Refresh balances and check Portfolio.

Should I enable collateral?

Collateral is supplied value that supports borrowing. The checkbox is a separate choice from supplying. Read the Collateral guide before using supplied assets to support a loan.

A supply rate can change. A displayed APY is not a promise of a fixed return, and supplying through a protocol is not the same as putting money in an insured bank account.

Check the result

A confirmed supply should be reflected in the supplied position after the data refreshes. ur wallet token balance should also change. An approval alone does not mean the supply completed.

If the action is unavailable, check the route status and remaining capacity. If the wallet rejects a later request after an approval succeeded, that approval can still exist. Inspect the receipt and current balances before starting again.

Words in this guide

Full glossary
APYAnnual percentage yield

Annual percentage yield: a rate expressed over one year with compounding included. It is not a guaranteed return.

Collateral

Eligible supplied assets enabled to support borrowing. These assets can be taken during liquidation if the position no longer meets its requirements.

Confirm supply in wallet

Starts the wallet requests for the reviewed supply. Read each request before accepting it.

Enter

The keyboard key used to activate a focused link or button.

ERC-20

A common Ethereum token standard that defines functions such as transfers and spending approvals.

ETH

Ether, Ethereum's native asset. It pays transaction fees on Ethereum.

Gas

The work needed to process a blockchain transaction. Fees use ETH on Ethereum and OP Mainnet, or AVAX on Avalanche, separately from the action token.

Health factorHealth-factor

A comparison of counted collateral to debt. Below 1, a position can be liquidated. Prices and interest can change this number.

HubHubs

The part of Aave V4 that manages shared liquidity and accounting. Connected Spokes use that liquidity under the Hub's limits.

Portfolio

The selected account's supplied positions and debt on the markets covered by this explorer.

PositionPositions

An account's supplied assets and debt within a market. One account can have separate positions in multiple Spokes.

Preview transaction

Checks the proposed action and shows its estimated effect before the main transaction is sent.

Protocol

The set of contracts and rules that runs a service such as Aave. The explorer is an interface for reading data and requesting actions from those contracts.

Refresh balances

Reloads the explorer to request current data. A recent transaction may take time to appear in indexed balances.

Review

Opens the action drawer for the selected route. Opening it does not move tokens.

SpokeSpokes

A market connected to Hub liquidity, with its own rules for user positions. Users supply and borrow through Spokes.

Supply

Moves the chosen token from ur wallet into the selected market after the transaction confirms.

TokenTokens

A digital asset recorded on a blockchain. Check the specific asset and network before entering an amount.

Token units

An amount of the token itself, such as 10 USDC or 0.5 WETH, rather than its estimated dollar value.

Token-spending approval

Permission for a contract to spend a particular token up to an allowance. Approval is a separate step from supplying or repaying.

TransactionTransactions

A signed request processed by the blockchain, such as supplying tokens or granting an approval. Review its receipt to check whether it succeeded.

View transaction

Opens the transaction receipt so u can check the submitted action and its result.

Wallet

An app or device that manages accounts and lets u approve transactions. Connecting a wallet is different from approving a payment or loan.

WETH

Wrapped Ether: ETH represented as an ERC-20 token. WETH and the ETH used to pay gas appear as separate balances.
