Swap Ethena (ENA)

ENA is an ERC-20 token on Ethereum mainnet, which makes it the most ordinary kind of token there is — and puts it on the most expensive network on this site. Figures were checked on 14 October 2026 at ethereum.org, docs.ethena.fi and against the contract.

Slots: every 12 seconds

ethereum.org describes Ethereum's proof-of-stake protocol as dividing time into twelve-second slots, each with one validator chosen to propose a block. Unlike Bitcoin's irregular ten-minute average, the slot clock is fixed: a block is expected every twelve seconds, and an empty slot simply passes. Blocks are later finalised by validator votes over epochs, after which they cannot be reverted; for a swap the count that matters is blocks, not finality.

What a confirmation is, and how many

A transaction is in a block once a proposer includes it, and each later block adds one confirmation. The route data this site is built from waits for 4 confirmations on an ENA deposit — fewer than the 15 it waits for on ETH itself; both figures come from the provider snapshot the site is built from. Four blocks at twelve seconds plus processing gives the 2–6 minute estimate on the status page.

Gas, and why it matters more here

Every ERC-20 transfer is a call to the token's contract, and the sender pays gas in ETH at the current base fee plus a tip, regardless of how much ENA moves. The sending wallet must hold ETH; a wallet with ENA and no ETH cannot send. The payout fee — the site's cost of sending ENA to you — is shown in the form, taken out of "You get", and is the dearest payout fee on this site, because an Ethereum contract call costs more than a transfer on any other network here. That is also why the form's minimum for ENA is higher than for coins on cheap networks: the fee has to fit inside the amount. USDT network fees compared shows the gap in numbers.

ENA, USDe, sENA: three tokens, one family

Ethena's documentation describes the protocol as "a synthetic dollar protocol built on crypto rails" that issues USDe, a dollar-denominated token "backed with crypto assets and corresponding short futures positions". ENA is a different token: the docs' ENA page calls it "the governance token of the Ethena protocol", used to govern the composition of USDe's backing, new backing strategies, the allocation of protocol revenue and the membership of the Risk Committee. sENA is "the staked form of ENA", an ERC-4626 wrapper with a cooldown before ENA can be withdrawn. Each has its own contract on the key-addresses page. The form pays and accepts ENA only.

The expensive network changes one habit. On TRON or BNB Smart Chain a small swap is cheap enough not to think about. On Ethereum the payout fee is the same whether you move a little or a lot, so compare the "You get" figure for the amount you have in mind with what a larger amount would give before you send.

An Ethereum address is 0x followed by 40 hexadecimal characters, 42 in all, optionally with the mixed-case checksum of EIP-55. BNB Smart Chain, Base, Arbitrum and every other EVM chain use the same format and the same keys, so the string alone never says which network it is for. Checked on 14 October 2026.

What the form accepts

For an ENA payout the form takes a 42-character 0x address and checks the hex characters and, where present, the checksum case. It cannot see which network the wallet behind it is set to. There is no memo on Ethereum. The deposit address the form shows for an ENA deposit is an ordinary Ethereum address; send ENA to it from a wallet on Ethereum that holds ETH for gas.

Which address to give

1. Your own wallet: the address from its Receive screen, on Ethereum. Every Ethereum-style wallet starts on Ethereum, so this is the default. If ENA is not listed after the payout, add it by the contract 0x57e114B691Db790C35207b2e685D4A43181e6061.
2. An exchange: open the ENA deposit page and pick Ethereum (ERC-20) if there is a choice. Use the address it shows. Ethena's docs list ENA on many other networks through LayerZero — a single address for most Layer-2s, and separate ones on Solana, TON and zkSync — and an exchange may list ENA on one of them; the form pays on Ethereum only.
3. Another person: ask for their Ethereum address and confirm they mean Ethereum mainnet; read the first and last four characters back.

ENA on other networks is a different token

The key-addresses page lists ENA at 0x58538e6A46E07434d7E7375Bc268D3cb839C0133 on most Layer-2s and on BNB Smart Chain, and at other addresses on Solana, TON and zkSync. Those are bridged representations, carried by LayerZero, and they are not what the form pays or accepts. A deposit of ENA on Arbitrum or BNB Smart Chain to the Ethereum deposit address is not possible — the address exists on those chains, but the token sent there is a different contract on a different network, and the swap here only sees Ethereum.

The three contracts in a wallet

ENA, sENA and USDe all show as tokens of the same project, and wallets list them by symbol. Before sending a deposit, open the token's details and compare the contract with the ENA address above; sENA at 0x8bE3…B3b9 and USDe at 0x4c9E…68B3 are not ENA deposits. Before pasting a payout address, there is nothing to compare — the form pays ENA, and the receiving wallet lists it once it arrives.

Both legs of an ENA swap on this site are on Ethereum, and the status page links them to etherscan.io. The fields below are what an Etherscan page shows, read on 14 October 2026.

What an Etherscan transaction page shows

A token transfer opens with the hash, the status (success or fail), the block number with its timestamp and confirmation count, and the time the transaction was first seen. Then the sender, the contract interacted with — Ethena (ENA) at 0x57e1…6061 — and an "ERC-20 Tokens Transferred" line with the sending address, the receiving address and the amount in ENA. Below are the value in ETH sent alongside (zero for a token transfer), the transaction fee in ETH, the gas price in gwei and the gas used against the limit, and the base fee and priority fee the transaction paid. Etherscan's token page shows ENA with 18 decimals and a max total supply of 15,000,000,000, and notes that the token's displayed name, Ethena, differs from the contract's own name function, which returns ENA.

A deposit you sent

1. Copy the transaction hash from your wallet's activity list.
2. Open it on etherscan.io. Pending means it is in the mempool waiting for a block — on Ethereum, usually because the gas price offered is below what proposers are including, which a wallet's "speed up" fixes. Not found means the wallet did not broadcast it, or it was on another network when you pressed Send.
3. Check "ERC-20 Tokens Transferred": the token must be Ethena (ENA) at the contract above — not sENA, not USDe — the destination the deposit address from the form, the amount what you entered.
4. Watch the confirmations. The status page here updates when 4 are reached, about a minute after the block.

A payout you received

1. Open the payout hash from the status page.
2. Find your address as the receiver in the tokens-transferred line. The amount is "You get" from the form — the payout fee was already taken out.
3. If your wallet shows nothing, check that it is on Ethereum and add the token by contract. Your address page on etherscan.io lists the ENA balance under Token Holdings either way.
4. Keep the hash. It is the evidence that the payout happened and what support on either side will ask for.

Reading the contract's history

The ENA contract was deployed in block 19,371,662, timestamped 21:29 UTC on 5 March 2024 — found for this page by searching an Ethereum RPC for the first block in which the address holds code. Etherscan's contract tab shows the same creation transaction, the verified source and the read-only functions, including totalSupply, which returns 15,000,000,000 with 18 decimals. What a block explorer shows about a swap covers the general case; Reading a swap status page explains each stage on the status page.

ENA's mistakes come from three look-alike tokens, from one address format shared by many chains, and from Ethereum's gas. None of them is subtle once named.

sENA and USDe

Ethena's docs describe sENA as the staked form of ENA — an ERC-4626 wrapper that is received when ENA is deposited into the staking contract, with a cooldown before ENA can be withdrawn again. It is a separate contract, and a wallet shows it as a separate token. USDe is the protocol's dollar token at another contract again. The deposit address the form creates for ENA is watched for the ENA contract only; sENA or USDe sent there is a transfer of a different token to an address you do not control, and nothing converts it. Unstaking takes the cooldown the docs mention, so plan the swap after it, not before.

The wrong chain, with the right address

Because the same key gives the same 0x address on every EVM chain, and because Ethena deploys ENA on many of them, it is possible to send ENA on Arbitrum to the Ethereum deposit address and see the transaction succeed. It succeeded on Arbitrum. The deposit address exists there too, but the swap watches Ethereum, and the token on Arbitrum is a different contract. Whether the deposit can be recovered depends on who controls that address on Arbitrum — contact support with the hash and the chain. Sent USDT to the wrong network is the same situation with another token and its decision tree applies.

Gas: too little of it, or too cheap

Two different problems. A wallet with ENA and no ETH cannot send at all, and the fix is to move some ETH in. A wallet that sends with a gas price below the going rate produces a pending transaction that may wait a long time; the deposit still belongs to the swap and is counted at its fourth confirmation, but the rate is fixed only then, so the estimate has longer to drift. Most wallets offer a speed-up that resubmits with a higher fee. Floating rate: estimate vs payout explains what the wait costs.

Small amounts on an expensive network

The payout fee is the same for a small swap and a large one, and on Ethereum it is large in absolute terms. The form's minimum keeps the fee from eating the payout, and it is higher for ENA than for a coin on TRON or BNB Smart Chain for exactly that reason. Minimums, maximums and network fees on small swaps shows how to read it.

Two checks cover the table. The token's contract in your wallet is 0x57e1…6061, and the network — in the wallet, on the exchange's deposit page, on its withdrawal page — is Ethereum. "ENA" and "0x" on their own are not enough.

ENA's history on chain is short and its governance history is longer than this page needs. The dated facts below come from the Ethereum chain itself, from docs.ethena.fi and from ethereum.org, read on 14 October 2026; what Ethena's documentation does not date, this page does not date either.

The deployment. The contract at 0x57e1…6061 first holds code in block 19,371,662, which Ethereum timestamps at 21:29 UTC on 5 March 2024. Its totalSupply reads 15,000,000,000 with 18 decimals, and Etherscan shows the same as the max total supply. The date the token was first distributed to holders is widely reported as April 2024, but Ethena's documentation does not state it, so this page records only what the chain shows.

Governance. Ethena's ENA page says ENA governs the composition of USDe backing, new backing strategies, the allocation of protocol revenue and the membership and remit of the Risk Committee, "a standing body responsible for setting risk parameters across the protocol" whose membership is itself subject to governance. Votes run through the governance forum and on-chain voting, and sENA holders vote on proposals concerning ENA specifically. For a transfer none of this applies; it is what the token is for once it is in a wallet.

Other networks. The key-addresses page lists ENA on a long list of Layer-2s at one shared address, and on Solana, TON and zkSync at their own, all carried by LayerZero. Each listing is a reminder that "ENA" on a deposit page needs a network next to it before it means the token this site handles.

Ethereum itself. ethereum.org's twelve-second slot has been the clock since the proof-of-stake transition; nothing in the chain's recent upgrades changed how an ERC-20 transfer is sent, confirmed or counted.

What has not changed. The contract, the 18 decimals, the 0x address, the 15-billion cap on the contract, and the need for ETH to move it. An address that received ENA in 2024 holds it at the same address today.

ENA and USDe come from the same protocol and share a chain, an address format and an explorer. They are different tokens with different jobs, and the site handles only one of them. Checked on 14 October 2026 against docs.ethena.fi and the two contracts.

What ENA is for. Ethena's docs put it in one sentence: ENA is the governance token of the Ethena protocol. Holders vote on the composition of USDe's backing, on new backing strategies, on how protocol revenue is allocated and on who sits on the Risk Committee; staking ENA into sENA signals long-term alignment and carries a cooldown before withdrawal. None of that happens through a swap here — the form moves ENA between two addresses and nothing more.

What USDe is. A token designed to be worth a dollar, backed, in the docs' words, "with crypto assets and corresponding short futures positions" rather than by bank deposits. It is a stablecoin in use, a synthetic dollar in Ethena's vocabulary, and it is not on this site. Someone who wants a dollar token out of a swap chooses USDT or USDC on one of their networks; ENA can be swapped for either.

Why the distinction matters for a transfer. A wallet lists both by symbol, both are ERC-20s with 18 decimals on the same chain, and both cost the same ETH to move. The only thing that separates them at the moment of sending is the contract — which is why the deposit address for ENA is watched for the ENA contract alone, and why USDe sent there is not a deposit. The same holds for sENA: a staked position is a different token until it is unstaked.

Same address, same explorer. The address that holds ENA can hold USDe, and etherscan.io lists both under Token Holdings. A transaction page for either shows the same fields; only the contract in the "ERC-20 Tokens Transferred" line tells them apart.
