Swap USD Coin (USDC)

USDC is simpler than USDT in one way and harder in another. Simpler: Circle issues it on every network here, with 6 decimals everywhere, and its contract list is the one place to check. Harder: three of the four networks share the 0x… address format, so the network can never be read off the address. The table was checked on 14 October 2026 against Circle's list and the chains themselves; the minutes are the estimates this site uses.

Ethereum: the original, and the dearest

USDC began on Ethereum, and the Ethereum token is the one most exchanges mean by "USDC (ERC-20)". A transfer pays gas in ETH, and at a busy hour a token transfer costs several times a plain ETH transfer. The site waits 15 confirmations, about 3 minutes of 12-second slots plus processing.

Solana: a token account, not a balance

On Solana a token is a mint, and a wallet holds it in a separate token account tied to the wallet address. The first USDC that reaches a new wallet creates that account, which has a small minimum balance in SOL; the sender pays it. To send USDC out, the wallet needs SOL for the fee. The site waits 1 confirmation.

Polygon and Base: cheap, and easy to confuse with Ethereum

Both use 0x… addresses and the same private keys as Ethereum, so one wallet shows one address for all three. A USDC balance on Polygon needs POL to move; a balance on Base needs ETH held on Base, which is a separate balance from ETH on Ethereum. Polygon has an older bridged token, USDC.e, next to the native one; the Key facts give the native contract.

Which to choose

The receiver's network, if named. Otherwise the cost line: enter the amount for each network and read "You get". Ethereum is usually the most expensive payout; the other three are usually cheaper, and between them the difference is often small enough that the receiver's convenience should decide. Routes that start from USDC: USDC ERC-20 → USDT TRC-20, USDC Base → USDT TRC-20, USDC Solana → USDT BEP-20, USDC ERC-20 → BTC, USDC ERC-20 → SOL.

Three of the four networks on this page use one address format, and the fourth uses another. That split is the whole story of USDC addresses, and it decides which mistakes the form can catch and which it cannot.

The 0x… family

An Ethereum-style address is 20 bytes written as 40 hexadecimal characters after 0x. Polygon and Base use the same scheme, and a wallet derives the same address on all three from one key. That is convenient: a hardware wallet shows one address, and USDC sent to it on any of the three networks reaches a wallet you control. It is also where the money goes missing: an exchange's deposit address on Ethereum looks identical to its address on Base, and the exchange watches only the network its deposit page named. The mixed-case checksum (ERC-55) catches a wrong character; nothing in the string names the network.

Solana: base58 without a prefix

A Solana address is a 32-byte public key in base58: 32–44 characters, letters and digits, never 0, O, I or l. There is no prefix because there is no network choice — SOL and USDC on Solana live on one chain. The form rejects a 0x… string for a Solana payout and a base58 string for an EVM one, so a Solana address is the one case where the format check protects you against the wrong network.

What the form accepts

For a USDC payout the form takes a 0x… address of 42 characters on Ethereum, Polygon or Base, and a base58 address on Solana. It does not accept an ENS name, a contract address you meant as a wallet, or an address from a different network family. The deposit address it shows you is an ordinary address on the network you selected, payable from any wallet or exchange withdrawal on that network.

Who to give which

1. Your own wallet: the address from its Receive screen, with the network set to the one you chose in the form. On Solana, a new wallet needs no setup — the token account is created by the first incoming transfer.
2. An exchange: the address from its USDC deposit page for that network, exactly as shown. Read the network name on that page; it is the only place it is written.
3. Another person: ask for the network in words first, then the address.

Pay USDT to a different network is written for USDT, but its logic for the 0x… family applies to USDC on Ethereum, Polygon and Base unchanged.

A USDC transfer shows up on an explorer as a transaction with little or no native value and a token transfer line that carries the amount. The pattern is the same on all four networks; the names differ. All four explorers were read on 14 October 2026.

A deposit you sent

1. Copy the transaction hash (on Solana, the signature) from your wallet.
2. Open it on the explorer of the network you sent on. If it is not there after a minute, the wallet did not broadcast it; on Solana a transaction can also expire unprocessed when the network is busy and the wallet will usually say so.
3. Read the token line: USDC, the contract from the Key facts, the amount from the form.
4. Check the receiver: the deposit address the form showed. On Solana the explorer shows both the token account and its owner; the owner is the address that matters.
5. Watch the confirmations. The status page updates on its own at the count the site waits for.

A payout you received

The status page shows the payout hash when the payout is sent. Open it on the explorer of the payout network. The token line names your address as the receiver and "You get" as the amount; the payout network fee was already taken out. Your wallet shows the balance once its own node has seen the block, which on Solana, Polygon and Base is seconds and on Ethereum a minute or two.

Reading a Solana payout

Solscan lists the transaction's signature, slot, block time, the result (Success), the fee in SOL, and the token balance changes. If this was the first USDC your wallet ever received, there is one more line: the creation of your token account, with its minimum balance in SOL paid by the sender. That is normal and costs you nothing.

What the explorer cannot tell you

Whether the owner of a 0x… address watches Ethereum, Polygon or Base. The transfer confirmed on one of them; the explorer of that network shows it; the owner's balance is the only proof it was the right one. What a block explorer shows about a swap covers the same reading for every network on the site.

USDC's mistakes come in two families: the wrong network behind an 0x… address, and the wrong token behind the name USDC. The rest are the ordinary ones of any token transfer.

Native and bridged

Circle's native USDC on Polygon has existed since October 2023; before that, USDC on Polygon was a bridged copy, now called USDC.e, created by locking USDC on Ethereum. Both still exist in wallets and on exchange pages. They are different contracts with different issuers, and a swap that expects one cannot take the other. USDC native vs bridged explains how to tell them apart and how to get from one to the other.

The empty fee balance

A wallet that holds USDC and none of the network's coin can receive more USDC and cannot do anything else with it. On Base the fee coin is ETH held on Base — ETH on Ethereum in the same wallet does not count. On Solana the fee is in SOL, and a new wallet that has only ever received tokens has none. USDT TRC-20 → SOL or USDC ERC-20 → SOL puts the fee coin into a Solana wallet with two addresses.

Solana: the minimum balance of a token account

Every Solana account must hold a minimum balance in SOL proportional to its size (Solana documentation, 14 October 2026). A USDC token account is one such account; the first transfer to a new wallet creates it, and the sender's transaction pays the minimum. For a payout from this site that is handled on the payout side. If you ever close the token account in your wallet, the next USDC that arrives creates it again.

Less than the minimum

A deposit under the route's minimum cannot be processed, because the payout fee has to fit inside it. The minimum is under the amount field; Minimums, maximums and network fees on small swaps explains how it is set. For a payout on Ethereum it is the highest of the four networks.

USDC's history on the four networks here is a history of arrivals, and of one replacement. The dates come from Circle's own blog and from the Solana Foundation's news page, read on 14 October 2026; the present state from Circle's contract list on the same day.

Solana, 2020. USDC came to Solana as an SPL token, with Circle as the issuer from the start. That is why USDC on Solana has never had a native-versus-bridged question: there was no bridged version to replace.

Base, 2023. Base launched with a bridged USDC and Circle's native token arrived on 5 September 2023. The native contract is the one in the Key facts and the one this site uses; a bridged balance from Base's first weeks is a different token.

Polygon, 2023. The replacement that still confuses people. Polygon had bridged USDC for years; when Circle issued native USDC in October 2023, the bridged token kept its contract and was renamed USDC.e. Exchanges switched deposit pages at different times. Today both exist, and a wallet can hold both. The Key facts give the native contract; the USDC native vs bridged post covers the rest.

Moving between networks. Circle runs a cross-chain protocol, CCTP, that burns USDC on one network and mints the same amount on another; its current version is V2 (developers.circle.com, 14 October 2026). That is how USDC can be native on 38 networks without a bridge holding collateral. A swap on this site is a different thing — a deposit on one network and a payout on another, with the rate shown in the form — and the route USDC ERC-20 → USDC Polygon is the one cross-network USDC page here.

What has not changed. 6 decimals on every network, Circle as the issuer, a contract per network, and the rule that a balance stays on its network until something moves it. Circle can freeze the balance of an address on any network where it is the issuer; that too has been true throughout.

Two dollar tokens, two issuers, eight networks between them on this site, and only one network in common. For a sender the choice is rarely about the token — it is about where the receiver is and what the payout costs. The comparison was checked on 14 October 2026 against Circle's contract list, tether.to and the chains.

Where the receiver is. An exchange or a person on Solana, Polygon or Base wants USDC; one on TRON, BNB Smart Chain or TON wants USDT. On Ethereum either works and the fee is the same kind of gas. The route pages above are the common crossings: dollars on an EVM network or Solana turning into dollars on TRON, and back.

The fee you cannot see in the form. Sending the deposit costs the fee coin of its network, and the two tokens live on different coins: ETH, SOL, POL for USDC; TRX, ETH, BNB, GRAM for USDT. A wallet that holds one dollar token and none of its coin is stuck in either case.

Rate. The estimate between the two stays close to one to one. What you pay is the payout network fee, taken out of "You get" and shown before you send; a payout on TRON or Solana keeps it small, a payout on Ethereum does not.

Two issuers, one habit. Whichever token you move, check the contract against the issuer's list once and keep the address. Circle's list is at developers.circle.com; Tether's at tether.to. Both were current on 14 October 2026, and both change when networks are added or retired.
